The precise language used in your paternity report is very important but, because it’s also very technical, it can sometimes be hard to understand. The report language is familiar to scientists, lawyers, and judges. To help with understanding your results, we’ve also shown you how they might say it on TV, instead of in a courtroom.
Your Report
IMPORTANT:
If you did an at-home peace-of-mind test, your report will not show the names of participants: participants are only identified by number and by their role in the test (for example, alleged father or child).
We include names of participants on the report only for witnessed, chain-of-custody tests.
Each paternity test report shows the following information:
- Conclusion
- Combined Paternity Index (CPI)
- Probability of Paternity
- Data table of DNA markers (or genetic systems)
The Conclusion states whether the possible father is EXCLUDED or is NOT EXCLUDED as the biological father (see explanations below). The data table lists the different DNA markers (or “genetic systems”) examined by scientists to create the CPI and Probability of Paternity.
Your Result
If the Conclusion reads, “is EXCLUDED as the biological father,” this means that he is NOT the father because the data in the table do not support a paternity relationship. When a possible father is EXCLUDED as the biological father, the Combined Paternity Index (CPI) is 0 and the Probability of Paternity is 0%.
If the Conclusion reads, “is NOT EXCLUDED as the biological father,” this means that he is most likely to BE the father because the data in the table strongly support a paternity relationship. When a possible father is NOT EXCLUDED, the Combined Paternity Index (CPI) is 100 (or larger) and the Probability of Paternity is typically 99.99% (or higher).
Why do TV personalities say “you are the father” while scientists say you are “not excluded as the biological father”?
Scientists use precise language, whereas TV personalities generalize for dramatic effect. DNA paternity testing uses powerful statistics to create a probability of paternity, and the highest probability possible is 99.99% (not 100%). Saying, “You ARE the father,” implies a 100% probability of paternity, which is technically incorrect.
So, just how powerful is a 99.99% probability of paternity?
A 99.99% probability of paternity is so powerful, that it’s routinely accepted as evidence in favor of paternity by genetic scientists, courtroom judges, and even the U.S. State Department. Although the scientific language is more technical than how they say it on TV, the bottom line is the same: a DNA paternity test probability of 99.99% is strong enough for a judge to confidently allow (or deny) child support, immigration, or even conviction in a criminal case. It’s also why a TV host feels confident enough to say, “You ARE the father.”

I have a question my ex did one over the mail and it came back 0%. Now im not the virgin mary so how is this possible
Identigene says
Thank you for your question. It is important to witness the collection of the samples when doing an at-home test. Were you able to be there when the samples were collected? Have in mind, mistakes can be made both unintentionally and intentionally. Our lab tests the relationship between the samples we receive, in no way can we verify a sample labeled “John Doe” actually came from John Doe. This is why witnessing is crucial to ensure accurate samples are received. I hope this helps answer your question. If you have any more questions or concerns, please call us at 1-888-404-GENE, Monday-Friday 9AM-6PM ET. Thank you for your comment!

barnisha says
OK I had a test done and the probability of paternity is 99.9% with one possible mutation was observed please explain to me more.
Admin says
Hi! It simply means that, taking into account the mutation, the analysts’ calculations put the probability of paternity for the tested man at 99.9%. We therefore consider that man to be the biological father of the child.
Alexandrea Purifoy says
I had a test done march 2014 can I still obtain those results? I tried getting them when I logged into my account but I kept getting an error report. Any assistance will b appreciated
Identigene says
Hi, Alexandrea. Please give us a direct call at 888-404-4363 for assistance
Ashley says
OK I don’t get how my home made results came back 0% but exp..dss818 child was 9,12 and father was9,11 relationship index was 10.48..so am lost is that mean does he have some d.n.a of his dad or what like d19s433 child was 29,33.2 and father was 29, relashinship index was 2.49… Like d351358 child was 15,17 and father was 15,16 and relationship was 0.82… All this numbers it don’t make since to me…n I kno I was loyal to this man…if this show no relationship then I have carried someone child who raped me…so with this being said please help me find out the truth behind my child father

Amelia says
My test came back with more than 6 matches and it was still 0%!!! How?! Could the results be inconclusive? Makes no sense. I’ve already emailed you guys and never heard anything back!!!
Identigene says
Hi, Amelia, and thanks for testing with us. It’s not unusual at all for a possible father and child to match at many genetic markers even if it turns out they’re unrelated. In fact, that’s very normal. Chances are good that you and I have several matches, since we’re human and we all have human DNA. Because a child gets 50% of their DNA from mom and 50% from dad, the child has to match their biological father at EVERY marker tested. Sometimes there may be one or even two mismatches allowed if there are genetic mutations, and those are taken into account by analysts as they determine the probability of paternity. With only six matches, that will always return a probability of paternity of 0% and the man tested is most definitely not the biological father. I’m sorry your emails weren’t answered…replies may have gone to your promotional or spam folder. If you have further questions, the best way to get hold of us is just to call: 800-344-9583.
kay says
Hi my test is exactly the same, am puzzled with it aswell.
J lady says
Hello Ashley,
Did you get an answer or get your issue resolved??? We’re you results actually correct? Considering your loyalty. I find my self in the same situation..
Brittney says
Ok I have a serious question. So on August 8th 2016 I got my first Untlsound it said I was 7 weeks and 6 days. I had sex on July 5th 2016. I had one DNA done it came back saying he was the father of the baby but the date are way off. How does that work?
Identigene says
Hi, Brittney. I can’t speak for the estimated gestational dates given by the ultrasound technician, but I can speak to the test results. It is absolutely impossible for a DNA test to “falsely” give a positive paternity result. It may be that the estimate on the ultrasound was simply off by a few days.
Kevin casey says
My man mom had two men she had sex with and I don’t looks him Ray belay one was 100 other was 97 only ho my dad
Identigene says
Hi, Kevin. Can you please rephrase your question? It doesn’t make sense. Thanks!
Centhy knights says
My child father did a dna test with out letting me no and it came back 0% and am 100% shure hes the father what should i do
Identigene says
Hi! If he had an at-home test done, then the results are not legally binding anyway. But if you really want to know if he is or isn’t the father, then you could request that he do a legal test, where the DNA collection is witnessed. Those results you can use in court, and because it’s a witnessed test, you can be sure the DNA he submitted is really his. You can learn more about it here: https://dnatesting.com/how-the-paternity-test-kit-works/paternity-test-for-child-support/
Jasmine says
My boyfried did a dna test on a baby that they are claiming is his , his brother is also accused of messing with the same person we did the dna and it came back 99.95 % does that mean he’s the biological father or is there a chance his brother can be the father ?
HomeDNA Identigene says
If his brother is another possible father, he needs to be tested also. It is possible to get a “false positive” result if the lab wasn’t notified that there is another possible father and that he is the brother of the man who was tested.
Richard says
I took a legal DNA test back in 2002, the results came to 83.7% why was there so much of a difference with mine than others?
HomeDNA Identigene says
Hi, Richard. The science has improved a lot in the last 17 years. So much so, that a result like yours would be considered inconclusive today. In order to get a positive result up to 99.9% or higher, we’ll test additional markers and/or add the mother’s DNA to the test in order to strengthen results.
Janell says
Good morning ,
My husband took a test about 4 years ago at the court house , the women and child were also there that day . When we got the test results in the mail it said 97.888 percent . I’m very confused on the number because he wasn’t excluded . Isn’t the percentage to low to say he’s not excluded ?
HomeDNA Identigene says
hi, Janell. that is considered an inconclusive result.
Austin says
Hey I have a question. My possible child and baby mom did a test three years ago with the other possible father. The results came back that he was excluded how ever the courts said that there is no way that he is her father. We are currently waiting on my results to come back but I dnt understand. Why would the courts say he’s not her father if the lab results came back saying that he is not excluded
HomeDNA Identigene says
Hi, Austin. Can you please clarify? Because the two statements you make are contradictory. First, you say the initial test said he was “excluded,” meaning he’s not the father. If that’s correct, then what the court said is true that there’s “no way that he is her father.” But at the end you say the lab results came back saying he is “not excluded” (is the father). So which is it? Thanks!
Dee says
I done a full-sibbling test on both my daughters to see of they both share the same father, the results was the probability of full siblingship is 0.6% what does this mean that that they do or dont share the same father?
Admin says
Hi, Dee. I don’t see your email address in our system, so I’m assuming you didn’t test with us, is that correct? Based on the information you gave, that tiny percentage of probability (less than 1%) most likely means that the girls are half-siblings and do not share the same biological father. Hope this helps!
Dee says
No i did not use your company as im from the uk but couldn’t get a straightforward answer to help me understand the results given till now thank you very much least i now know who my littles ones father is.
Admin says
You’re very welcome, Dee. Glad to help!
Leanne says
Hi I had Dna test done and came back o% but my daughter amelogenin says x and alleged father is xy but apparently there not a match what does this mean also some of there fingers are similar but had a 0 percent and excluded out of the biologically father
Admin says
Hi, Leanne! The amelogenin is the sex chromosome. Males have XY at that location and females have XX. On your paternity-test report, Your daughter’s will show as just X instead of XX, which is absolutely normal when there’s a duplicate figure in a report. She got one X from her biological mother and the other X from her biological father. The amelogenin is not used to determine paternity, only the sex of the participant. It is the other loci where the matches matter in terms of paternity. If even one number doesn’t match up with the man tested, then the lab does not consider the man tested to be the biological father and the probability of paternity will given as 0%. I’m not sure what you mean by their fingers are similar? However, looks alone are never an absolute determinant of paternity. I hope this helps!
Jane Sims says
My son took a dna test October 2015 and his dad took a separate test September 2016 are those results accurate
Admin says
Were the results different, Jane?
La says
Did u get to retake and what was the problem
Shane says
Quoted text from this page…
“If you did an at-home peace-of-mind test, your report will not show the names of participants: participants are only identified by number and by their role in the test (for example, alleged father or child).
We include names of participants on the report only for witnessed, chain-of-custody tests.”
On my “personal” analysis report it has the participants names right on the page!
This was not a chain-of-custody report I purchased. Even says it at the bottom…
Why would a piece of mind report include names?
And why does it use combined “relationship” index & probability of “relationship” instead of combined “paternity” index??
This is crazy. Not even sure what I purchased.
Identigene says
Hi, Shane. Before Identigene was purchased by our parent company DDC, names were included on peace-of-mind tests. But effective December, 2016, they no longer are. The reason, quite simply, is that DDC had a different process in place and just carried that process over to Identigene following the purchase. A “relationship index” is the same thing as a “paternity index” in the context of paternity testing. These minor differences don’t make test reports any less accurate.
Yesenia says
Hi if 99.8 is a result of DNA what that means he is the father?
Identigene says
Hi, Yesenia. Yes, it does.
Jennah says
My husband had a paternity test done and it came back 0% probability of paternity is this guaranteed or how accurate would it be if you were guaranteed that the man and child being tested was the correct one being swab?
Identigene says
Hi, Jennah. You can be sure the results of the paternity test are correct for the samples that were submitted, if you used an accredited lab like Identigene’s. We guarantee the accuracy of our results. With an at-home test, we have no way of knowing if your husband actually submitted his own DNA or someone else’s. If you’re not sure, you should probably test again, and this time do a legal test where DNA collection is supervised by an approved and impartial witness. Then you’ll know for sure if he submitted his own DNA for the at-home test. Identigene can arrange for a witnessed collection near you…just give us a call at 888-404-4363.
Anna says
Ok my husband did a test quite a few years back on a child he shares w/ his ex he says it was a low 90%. Doesn’t have the test results # ect from what I understand unless it is 98.99% atleast, he’s not the father correct? Dates of gestation ultra sound and birth records more than 2 weeks before their 1 night stand. Also can he get his test results w/o # ?
HomeDNA Identigene says
Hi, Anna. You weren’t specific about how long ago the test was, but it must have been quite a while ago since he was issued paternity-test results that weren’t either 99.9% or higher or 0%. Those test results are long gone. They are not kept on file for more than 1-5 years, for security reasons. If at all possible, he should do another test if all parties are willing.
Rhonda Vernon says
Hello. I did a dna test with someone that is my siblings uncle. The results showed index: 2.4 an probability: 70%. Does that show a direct relation between me an that person? It was an uncle/niece test that we did. Thank you
Identigene says
Hi Rhonda,
Thank you for your question. Anything under a 99% or over 0% is considered an inconclusive result. This means no concrete result was reached. Did your biological mother or any other first degree relatives test? Typically in an avuncular test, inconclusive results will happen because there was not enough DNA or other participants to help reach a solid “yes” or “no” answer. I hope this information helps. Please call us for any more questions regarding your test and results. You can reach us at 1-888-404-GENE, Monday-Friday 9AM-6PM ET. Thank you for your comment!
Thereasa says
With regards to the question of whether these two individuals are full or half siblings, they are 90342 times more likely to be half siblings with a probability of 99.99%. With regards to the question of whether they are half siblings or unrelated, they are 4 times more likely to be unrelated with a probability of 80.59%. A prior probability of 0.5 was assumed.
So what does this mean. Is it 100% that this is not my sibling …half or whole?
IDENTIGENE says
Hi, Thereasa. Please call our Client Support Center at 888-404-4363 for help understanding your results. You can also live-chat during business hours if you prefer at DNAtesting.com.
Step says
Uhmm I have a ? I’m a first time mother I took a text with my child’s father & the text came back 99.999999999% I just want to kno for sure that’s means his the father?
Identigene says
Hi! It means that yes, we consider the man tested to be the biological father.
crystal25 says
i have a question if you do a paternity test and the result was 99.38% and they said he is not excluded unless there is another party to be tested….what does that mean?
Identigene says
Hi Crystal25,
Thank you for your question. Typically, the statement refers to testing another possible alleged father, usually a first degree relative to the alleged father already tested. Was the biological mother included in the test? Have in mind, including the mother can strengthen results as well. If you have any more questions, please call our friendly client support at 1-888-404-GENE, Monday-Friday 9AM-6PM ET. Thank you for your comment!
Lara says
How important is it to include the mother in DNA test, or can not including the mother adversely affect the results?
IDENTIGENE says
Hi, Lara. In the vast majority of cases, we don’t need the mother’s DNA in order to get conclusive results. Nevertheless, each of our kits provides testing materials for the mother and we recommend she send in samples too, just in case they’re requested by the lab to confirm or strengthen results. NOT including the mother’s DNA will not adversely affect the results.
marquita says
Hi I had a DNA test done and it came out 0.5 what does that mean…
IDENTIGENE says
Hi, Marquita. Without seeing your report, it’s hard for me to comment. I’m going to assume (and this is just an educated guess), that the 0.5 number the lab you used gave you means that there is a 50% chance the man tested is the biological father. A reputable lab will not release a probability like this. Rather, it would show either a 0% probability of paternity for a negative result or 99% or higher for a positive result. I suggest you contact the lab you tested with and have them clarify.
Shantel says
I have a question I took a test with two guys at the same time I saw both take the test the lab was not informed one child was tested by two guys it came back 99.97 for one but it cannot be possible cause the time don’t add up for the guy and now I was informed the other guy is kin to me do you think I can test the guy again?
HomeDNA Identigene says
Yes.
Zelda says
When my child was a new born about 5 months his father decided to do a DNA test and not sure if he followed directions properly but I was not included in the test but I did pay for it. I tried to call and they asked me to do a test and I never got the swab in the mail. Now the father is telling me he never completed the test (obviously) and wants to do it again but I’m not paying for another test. They said the test was less than 99% and that’s why they needed my samples , now from my understanding this means more than 3 but less than 6 marks matched or somthing correct ? And I’m also wondering if this man was not related to the child at all would the results come back 0 percent or can DNA results be between 1 and 99 percent even though they are not related? Anyway I want to send my sample but this was 2 years ago not sure if they still even have the DNA on file.
Admin says
Hi, Zelda! Sounds like it’s time to start again from scratch, just to finally have peace of mind and absolute knowledge. In most cases, the mother’s DNA is not needed for conclusive results, but we recommend she test too, for the reasons you mentioned. A conclusive paternity test is one with results of 99% and higher or 0%. Anything in between is inconclusive. Without seeing your report, this is complete speculation; but it sounds as if your DNA was needed to push results over that 99% threshold, so the man tested may very well be the biological father. If even one marker didn’t match him at all, they would have come back with 0% paternity. Is the man willing to test again? That would be best.
wayne says
Hi I have had a DNA test done and they said I am the Adjudicated father what does that mean? And I found out that my cousin had sex with the mother multiple times right before she became pregnant does this mean because we have the same blood line that he could be the father and if so how do I get the court to find out? He has another child so his DNA is already in the system would that help?
Identigene says
Hi Wayne,
Did you test with IDENTIGENE? If not, you may want to consult with the company you tested through for more specific answers to your results. ON behalf of IDENTIGENE, we can inform you that cousins have significantly different DNA, even brothers with the same parents can be tested with enough differences in DNA to obtain results. We recommend testing any two individuals in question for paternity if they are related. I hope this information helps. To set up or order a test, please call our friendly client support at 1-888-404-GENE, Monday-Friday 9AM-6PM ET. You can also find our kit at your local CVS, Walmart and Rite-Aid locations. Thank you for your comment!
nicole says
Have 6year old and 1 year old different DNA strengths CPI one is 35,000,000 to 1 and other is 25,000,000 to 1 does age play a part in strength?
Identigene says
Hi Nicole,
Thank you for your question! The CPI statistic is a unique number generated between two people and their DNA. The CPI and the percentage of probability will match up. For example, if a person is excluded from paternity, the percentage will be 0% and the CPI will also be 0. When a person is considered the biological father, the percentage will be over 99% and the CPI will read as a number over 100. In a way, the CPI is a different way to report the percentage of probability. The strength can more easily be read in the percentage following the result statement.
I hope this information helps. If you have any more questions, please call us at 1-888-404-GENE, Monday-Friday 9AM-6PM ET. Thank you for your comment!
Antanisha Smith says
Can breast milk affect the results of a dna test
Admin says
Hi, Antanisha! We tell our customers not to eat or drink anything for one hour prior to collecting samples, even breast milk. If a baby has breast milk before their cheek is swabbed, there’s a chance the quality of the DNA sample could be affected, but it doesn’t change the DNA itself. If the sample’s degraded, the lab would ask for a new sample before doing the testing. So it doesn’t affect or change results.
Ike says
I did one on myself for for my son its been 4 days and i haven’t receive the results back. should i be worried
Identigene says
Hi Ike,
Has it been four days since you sent the samples? If so, have in mind the mailing frame is 5-7 days (if using our envelope) until it arrives in our lab. If you provided an email address, you will receive a notification to let you know testing has begun. It will take 2 full business days for testing AFTER samples arrive. I hope this information helps. If you have any more questions, please call us at 1-888-404-GENE, Monday-Friday 9AM-6PM ET. You can also check the status of your case by logging in online. Thank you for your comment!
salll says
I bought an at home kit from the drug store but do I still have to create an online account and pay the lab fee there?
Identigene says
Hi Salll,
In order to get results and get testing started, you will need to pay the additional $89 lab fee. Online registration and payment is a fairly new feature now available to you. However, we are more than happy to assist you set up your account and take the payment over the phone as well. You can reach us at 1-888-404-GENE, Monday-Friday 9AM-6PM ET.

Other was 567,800 CPI CAN THAT MEAN THE CHILED WHIT LOW CPI IS LOW CHANCE THAT SHE SLEEP WHIT MY FRIST COUSIN MY DAD HIS DAD IS BROTHERS THE TOO WHIT HI CPI LOOK LIKE ME THE OTHER LOOK MORE LIKE HIM BUT WE GOT 15 marks that Mach ????? Please help
Identigene says
Hi Joe,
Thank you for your comment! If there is any possibility of a first degree relative, such as a father or brother, we highly recommend having them test as well. Please call us at 1-888-404-GENE Monday-Friday 9AM-6PM ET for any more questions or concerns! Thank you.
octavia says
My daughter did a dna test against tge guy I thought was her father. It came back 5% that he is the father. Meaning 94% he is not. What does this mean? How is this possible
Identigene says
Hi Octavia,
Based on the results, it sounds like the alleged father was excluded from paternity. Were you able to witness the collection of the DNA samples as well as the sending off of the samples? Have in mind that mistakes can be made intentionally and unintentionally. It is important to witness the samples being collected as well as sent off in order to ensure the correct samples were received. We cannot verify a sample labeled “John Doe” is in fact from John Doe. If you have a question or concern, please call us at 1-888-404-GENE, Monday-Friday 9AM-6PM ET. Thank you for your comment!
Felicia says
My paternity test on my di-di twins came back as 99.99%. All their markers matched. Does that mean them identical? Would regular siblings share the exact same numbers on their alleles, everywhere?
Admin says
Paternity test results are not an indicator of whether or not your twins or identical or fraternal. If the man being tested is the biological father of both twins, the results will be 99.99% for the paternity test, even if the twins aren’t identical. If you did indeed swab each child separately and submitted both children’s samples, if each marker matches, then it can be assumed they are identical. Fraternal twins’ markers would have differences, since their genetic relationship is that of regular siblings.
cherlyn says
I would like to know if my brother and I take this DNA test will this verify if we are full brother and sister or half brother and sister? Our mother recently passed and the father is refusing to take the test so I was told since he is the son of this fella and first born, it would be another way of getting results. Will I get a true and accurate result this way? I do not think I could get a court order after all these years and it would probably be costly too. Please advise. Thank you CP
Identigene says
Hi Cherlyn,
We do offer a test for siblings, however, it is not the same kit as the paternity test found in super centers. In order to get that set up, we recommend calling our friendly client support team. We do also recommend to have the biological mother tested in order to increase the chances for a conclusive result. The sibling test is $399 and can include up to 5 people, usually first degree relatives. For more information please call us at 1-888-404-GENE, Monday-Friday 9AM-6PM ET. Thank you for your comment!
Ella says
I did a paternity test with my estranged husband. I have no memory of having intercourse with him near the time of my son’s conception. My son looks exactly like the man I was seeing at the time. The DNA test said that my estranged husband is the father, but the CPI is only 97.83. Also, my husband and I match on 14 points of the test. What does this mean?
Identigene says
Hi Ella,
Thank you for your comment! While looks are important, it is not accurate to base relationships solely from visual traits. Were you able to witness the collection and sending of the samples? Have in mind that mistakes can be made both intentionally and unintentionally. With your result being a 97.83%, it is considered an inconclusive result. Was the biological mother included in the test? If not, we recommend including the mother because she can help strengthen the result of the test. Is the other potential father a relative of your estranged husband? If so, this may be a reason to have both of them tested.
Human DNA is very similar, for this reason it is very common to see some matches with many others, not just your husband.
If you have any more questions or concerns, please call us at 1-888-404-GENE, Monday-Friday 9AM-6PM ET. Thank you for your comment!
Priscilla says
I did a paternity test on my husband and his daughter but the biological mother was not inculded because she does not know. But if the test comes back saying 98.37% I know it means its inconclusive but does it mean there is more of a chance that he is than that he isnt the father. We did it this way cause through court its more expensive?
Identigene says
Hi Priscilla,
Thank you for your patience! You are correct, with a 98.37% it is considered an inconclusive result. Typically this will happen because the mother did not participate. However, your result is leaning towards him being considered the father. The only way to conclude this for certain (or any result) is to include the mother or test anyone else that may be related to the alleged father if they may be a potential candidate for paternity as well. I hope this information helps, and please call us if the mother’s sample can be sent in. That is the easiest and best chance to obtain a conclusive result. You can reach us at 1-888-404-GENE, Monday-Friday 9AM-6PM ET. Thank you.
Sarah says
I seen on server websites that you all have giving wrong results or they have taking a test twice and gotten 2 different results. . My boyfriend took one without me knowing && it said he is not the father && I kno i wasn’t with anyone else. He said maybe he did it wrong cause he feels our lil girl is his
Identigene says
Hi Sarah,
Thank you for your comment. There have been cases where people do in fact take two tests and receive two different results. Have in mind that paternity fraud is real, and does happen. Mistakes can be made intentionally and unintentionally. You can visit this page, which will explain receiving different results from two labs: http://dnatesting.com/i-got-different-results-from-a-different-lab-how-is-that-possible/

my boyfriends mother did a test for him. it came back cri 0.0385 it says the probability of relatedness is 3.7% and the likelihood the alleged relative is not the biological relative is 26 to 1. this means they are not related right? because I still have the babies mother trying to tell me hes the dad
Identigene says
Hi Briane,
Based on the numbers you have given me, a 3.7% is considered an inconclusive result. This means that a solid “yes” or “no” could not be reported. Is there a possibility of another first degree relative being an alleged father? Was the mother included in the test? We highly recommend having the biological mother tested in order to increase the chance of a conclusive result. If you have any more questions or concerns, please call us at 1-888-404-GENE, Monday-Friday 9AM-6PM ET. Thank you for your comment!
Tara says
My son had sex with this girl and then 2-3 days later had sex with another guy (unprotected) now she has a child and we dont know which guy is the father. Can these DNA test tell which one is the father, and once you receive the results how do you read them. I have been looking online and I cant figure it out :( Thanks
Identigene says
Hi Tara,
Has the baby been born? If so, we can definitely do a paternity test which you can get from your local Walmart, Rite-Aid, CVS or independent drugstores. When you receive results for the test, we report a “conclusion statement” which will give you the result or whether the father is considered the father (not excluded) or is not the father (excluded). We do also offer pre-natal DNA testing, however it is a more intensive process and would need to be cleared by the doctor. If you have any more questions about either one of these tests or reading results, please call us at 1-888-404-GENE, Monday-Friday 9AM-6PM ET. Thank you for your comment!
aalysha says
Hi yesterday tested me, my baby, and a possible father and sent it in today. I made an account but I didn’t find out about the setup until after I sent it in will that mess up me getting the results.? Also there is another possible father of my child that I did not test will that mess up the results.
Identigene says
Hi Aalysha,
If you have sent in the order form and payment you will be fine. Whether you fill it out online or by mail will not affect your results delivery. You will still be able to log on and view your results if you provided a username and password on your order form. Is the other potential father related to the one you have sent in? If so we recommend testing both of them along with the mother. If not, you can always wait to see the outcome of your first alleged father test and you can always send in the second alleged father’s DNA within the first 30 days of testing and add him to the test. I hope this information helps. If you have any questions, please call us at 1-888-404=GENE, Monday-Friday 9AM-6PM ET. Thank you for your comment!
Tia says
I had the alleged father and my child take the test. She took the test and I witnessed it and I put it in the envelope. I then flew to meet the alleged father so he could take the test. 4 days later the alleged father took the test and I witnessed it and I put it in the envelope. I then mailed it myself 2 days after that. My question is; can xraying the DNA already in the box from the airlines cause a negative result? Can keeping the DNA too long in the envelope cause a negative result?
Identigene says
Hi Tia,
Thank you for your question! We are glad to hear you witnessed the sample collections from all parties. This can help prevent mistakes whether intentional or unintentional. DNA will not change from exposure to radiation from x-rays, so your samples are fine. DNA is also good for up to 6 months after the samples have been collected. I hope this helps answer your question. If you have any more questions or concerns, please call us at 1-888-404-GENE, Monday-Friday 9AM-6PM ET. Thank you for your comment!
Catherine says
My boyfriend used one of your DNA test on my daughter without me knowing. I know I have not been involved with anyone else. The results say that they match on several different markers, but it says it’s a 0 to 1 possibility that he is the father. How is that even possible? I’m pretty sure some of her genes come from me also. How would it change if the mother is added to the equation?
Identigene says
Hi Catherine,
Thank you for your question. In this case, we recommend the collection of the samples is witnessed to ensure the correct samples were sent in to our lab. Know mistakes can be made both intentional and unintentional. We cannot ensure a sample labeled “John Doe” is in fact John Doe’s DNA. This is why witnessing collections is important when there is any doubt of result outcome. Your child does get half the genes from each parent. This is why including the mother is always recommended, but never required. (unless the case requires her to obtain a conclusive result) With your result, you achieved a conclusive result, which means including the mother was not necessary to obtain a solid “yes” or “no” answer. If you have any more questions, please call us at 1-888-404-GENE, Monday -Friday 9AM-6PM ET. Thank you for your comment!
Chanice Baptiste says
My husband took a dna without the mother involvment. The test showed 0 to 1 and the probability was 0.00%. It also say that he is not the father. I will like to know with the mother involvment can the results change or will it remain the same.
Admin says
Hi, Chanice. In the overwhelming number of cases, the mother’s DNA is not necessary to get conclusive results. If your husband did, in fact, submit his own DNA as well as that of the child, then you can trust the results.
Megan says
My S/o and I sent in our samples around the 17th of December, still no results.. why?
Identigene says
Hi, Megan. If you used the prepaid mailer included in your kit, it can take up to 10 business days (not including weekends or holidays – like Christmas) for the envelope to reach our lab. So it’s probably still on its way. Once your samples arrive and testing begins, results are back in one business day, as indicated on the kit.
aalysha says
No they are not related. And I don’t know if I provided a username but I know I provided a password the username is my email address
Identigene says
Hi Aalysha,
Correct, the email address (if provided) would be your username. Have in mind you can send in samples for a second alleged father after the first one is tested. You have 30 days to add participants to an existing case. Thank you for your comment!
Justin says
I have a weird question…I heard that someone supposedly had a baby with their Uncle. Now what I want to know is if I were to make that person take a DNA test if you would be able to tell that they are related?
Identigene says
Hi Justin,
I am having some trouble understanding which relationship you would like to test. The one between the child’s mother and her uncle or the child and the alleged father. Whichever one it is, we do have tests available. Depending how many people are available for testing, we can suggest a test for you to take and order. In order to better help your situation, please give us a call at 1-888-404-GENE, Monday-Friday 9AM-6PM ET. We are more than happy to take your call and give you the best option for your case! Thank you for your comment and patience.
Robyn says
Hi. So back in 1988 my mother had paternity testing done on a couple men to determine my father. There was a ton of scandal and heartbreak surrounding this. I am now in my 30s and can continue not knowing. So i have begun the process all over thru identigene… my question is how do i find out who all was originally tested when the state did it and how can i get it f one again quickly ? My mother swears only 5men were tested and now one of the men says there are more than that… please help me identigene? There were only 7markers tested and the lab back then i researched and they have lost so many lawsuits due to false reports its sickening…
Identigene says
Hi Robyn,
I am understanding you did not do this test through IDENTIGENE originally. While we cannot comment on another lab’s process or results, we can recommend you call us to set up your test with us. Our turn around time is 2 full business days and we also have a rush option available if you need your results faster. We are a highly accredited lab, with highly trained professionals. You can see our accreditations here: http://dnatesting.com/paternity-test-laboratory/accreditations/

cath says
I had a DNA sibling test done on my daughter’s to try and see if they are full sisters or half. I included a sample from me too. The results came back at 89% and a conclusion that this would mean they are full sisters. I was under the impression that as my sample was included the percentage should have been higher? Thanks
Identigene says
Hi Cath,
Thank you for your comment! With an 89% result, it is considered an inconclusive. More than likely, this means that there was not enough DNA to give a stronger result. Are there any other first degree relatives willing to test? We highly recommend including more first degree relatives in order to obtain a conclusive result. Please call our friendly client support at 1-888-404-GENE, Monday-Friday 9AM-6PM ET so we may assist you and talk about more specific options. Thank you for your patience!
Rayon says
I did this test. But I wasn’t the one that sent it off. So I want to know if your test consider race. In terms of mix children. My son has an Asian mother and I am black. I don’t know if she switched the samples. So does the test considers race into it?
Identigene says
Hi Rayon,
It is important to mark the envelopes correctly. One of the requirements is ethnicity for each participant. If you are unsure of a possible switch within samples, we recommend letting our lab know by calling our friendly client support at 1-888-404-GENE, Monday-Friday 9AM-6PM ET. Thank you for your comment!
Tabitha says
My ex did a DNA test for our daughter but the results came back saying he was not the father. I was not there to witness him taking the test nor did they ask me to take the test. And I didn’t sleep with anybody else could the test results be 100%?
Identigene says
Hi Tabitha,
Thank you for your patience! We do highly recommend to witness the collection and sending of the samples to our lab. We also do not require the biological mother to test, it is however highly recommended. If there is any reason to believe the samples may have been tampered with, we highly recommend doing a court-admissible test. Mistakes can be made both intentionally or unintentionally, this is why it is important to have the collection witnessed. Our lab cannot verify if a sample labeled “John Doe” did in fact come from John Doe. If you continue having any questions or concerns, please call us at 1-888-404-GENE, Monday-Friday 9AM-6PM ET. Thank you for your comment!
lanika says
If a test comes back and it says 99.9% what do that means
Identigene says
Hi Lanika,
With a result of 99.99% probability, this means the tested alleged father is considered to be the biological father. This is the highest probability a DNA test can result in. If you have any more questions on your results, please call us at 1-888-404-GENE, Monday-Friday 9AM-6PM ET. Thank you for your comment!
Christina says
I was wondering. . . A home dna paternity test was done. The mother did not provide a sample. The child and posible father did, but The mother was the one who mailed it. Now we saw the sample go into the envelope. . . But is it possible the mom could of gotten another test behind our back, submitted her sample in place of the father? I ask because the child shows the x int the bottom box….except the posible father shows x/y ? Was the father’s sample checked to see if it was from a male or female?
Laura says
Hi
I have a question my daughter match 10 out of the 15 and its saying corresponding to a probability of paternity 0% assuming prior probability equals 0.5
combined relationship index 0 To 1
and the relationship index column has a dash mark with no number
also this test was done between father and childhe the father has a girlfriend I think that may have contaminated or messed with my daughters Test before mailing it to lab…and the father had an XYon the test what does that mean
Identigene says
Hi Laura,
Thank you for your patience! For someone to be considered a complete match, ALL markers must match, once a test reaches more than three mismatches, the result is found to be exclusive (or not related.) If you have doubts about the correct samples being sent it, we recommend doing a recollection and witnessing the DNA collection as well as the sending off of samples. Another option is having the test done as a court-admissible test, this means a third party will conduct and collect all samples diminishing chances for mistakes to be made. I hope this information helps, if you have any more questions, please call us at 1-888-404-GENE, Monday-Friday 9AM-6PM ET. Thank you for your comment!
dine says
My husband and my daughter took a blood dna test .MYSELF AS THE MOTHER DID NOT TESTED. THE TEST CAME BACK HE His indeed the father I wanted him to be the father but, I’m still doubt he his not because I got involved with pastor don’t remember if my husband and I have sex.now I wanted to test the other guy he refused he said he doesn’t want to mess up his reputation as pastor. I need help I’m going to deeply stressed
Identigene says
Hi Dine,
Thank you for your question. Unless the tested man that came back as the father has a twin brother or close family members as potential father, the chances of him not being the father are very slim. What was your percentage of probability? If it was anything above 99% that is one of the highest probabilities possible in DNA testing. We also recommend the correct samples were sent in, meaning you witnessed the collection and sending of the samples. If you have any more questions, we ask you to call us at 1-888-404-GENE, Monday-Friday 9AM-6PM ET. Thank you for your comment!
Darlene says
A friend of mine had paternity testing done for three children around 1990. One came back that there was a 99.9 % probability he is the father and one had a 0% probability. But the third came back as inconclusive with a 70% chance. After all this time he probably won’t retest but was just wondering with the advances what that meant back then.
Identigene says
Hi Darlene,
Thank you for your question! It sounds like two results were conclusive, and the other inconclusive. Getting a conclusive result means anything above 99% or below 0%. When there is a percentage in between 0-99% it is referred as an inconclusive result. This typically means there was not enough DNA to determine or establish a concrete relationship. This usually happens with the biological mother of the child was not included in the DNA test. Identigene recently lowered the paternity test lab fee to $89. If you would like more information or to order a test, please call us at 1-888-404-GENE, Monday-Friday 9AM-6PM ET. Thank you for your comment!

Malissie says
My son just had a baby she is 4 months old and he is in doubt of it being his i know to get an accurate result you need the biological mother of the baby. but if that is not possible can the biological mother of the father be tested along with the baby so that the results can be accubaby.so we don’t have to include the biological mother of the baby
Identigene says
Hi Malissie,
The biological mother of the child is not REQUIRED for testing, she is highly recommended to be included. However, we do understand there are circumstances when the mother cannot be tested and there are other alternatives incase the mother is needed for testing. When the biological mother is not included in testing, there is a chance the results may be inconclusive, however this chance is fairly rare. Have in mind, proper consent must be given to test the child from the legal guardian. I hope this information helps. If you have any more questions, please call us at 1-888-404-GENE, Monday-Friday 9AM-6PM ET. Thank you for your comment!
Ruby says
Hi I recently tested my daughter and cousin for sibling test the report said 28% inconclusive what does this mean? Thankyou
Identigene says
Hi Ruby,
I’m having some trouble understanding who was the unknown person tested. Typically, with an inconclusive result, it means there was not enough DNA to determine a concrete “yes” or “no” answer. Are there any other first-degree relatives willing to be included in the test? With a sibling test, up to 5 people can be included in testing and it is highly recommended to include as many first degree relatives as possible in order to minimize the possibility of an inconclusive result. Our friendly client support is more than happy to assist you in detail according to your specific case. Call us at 1-888-404-GENE, Monday-Friday 9AM-6PM ET. Thank you for your comment!
TAJ says
What does it mean when the CVS DNA says 200 .Does that mean he still the Father.???

kay bell says
good day, the Alleged father did a test on the twin girls, without the mother, the results came back PI 0 and prob 0.00%…she states there is no other prospect, is it because she was not on the test that it could have been miscinstrued…
there were 13 markers that matched and 9 that didn’t find traits
should a new test be done with all 4 or is it a waste of time?
Identigene says
Hi Kay Bell,
Typically the mother is only required to be tested when the results come back as inconclusive. This means the probability of relationship is above 0% but below 99%. With a solid 0%, your results are considered a conclusive. Were you able to witness the test? Sometimes mistakes can be made intentionally or unintentionally. We want you to be sure the correct samples were sent in for the person wanting to be tested. With markers, all of them must match to be a confirmed relationship for paternity. With any more than three “mis-matching” markers, the test is an exclusion for paternity. I hope this information helps. If you have any more case specific questions, please call us at 1-888-404-GENE, Monday-Friday 9AM-6PM ET. Thank you for your comment!
Sam says
I just recently did a DNA test with my ex and her new born daughter, we did test the mother and myself and i witnessed the samples being collected and personally mailed them in myself. The results came back with 0.00% chance of being the father, however 4 of the 15 genes tested of mine did match her daughter. Now im just curious as to if this is common to have a few matching genes, are some just that common or no? Also she recently tested another man who could be the father we are currently waiting on those results, im just curious as to if the 4 of the 15 matching genes is common when the child is said to not be mine?
Identigene says
Hi Sam,
Great question! With human DNA, it is common to see some “matches.” However in order for a genetic relationship to be established, all markers must have a match. This means all 15 must match with the child’s 15 markers. Anything more than 3 mismatching markers is considered to be an exclusion. I hope this helps answer your question. If you continue to have more questions or concerns, please call us at 1-888-404-GENE, Monday-Friday 9AM-6PM ET. Thank you for your comment!
Genet says
Hi I gat DNA and my mother also she take DNA test .So the resalt is 99.9999999% please can you take me what das mine.
Identigene says
Hi, Genet. I’m sorry, but I don’t understand the question?
Robert says
Hi I just done a paternity test and the results were 6 of 15 did not match what does this mean is there any chance we could be related?
Identigene says
Hi Robert,
In order for a relationship to be established between two participants, all markers need to have a match. With any more than 3 mismatching markers, the chances of being related is considered 0%. If you have any more questions, please call us at 1-888-404-GENE, Monday-Friday 9AM-6PM ET. Thank you for your comment!
Ruby says
Hi thank you for your reply, mother niece and daughter were tested and the combined likelihood ratio cpi was 0.40 we would love to know if the girls are just cousins or not unfortunately there isn’t anyone else available to contribute.
Identigene says
Hi Ruby,
Unfortunately our test cannot tell you if there is a relationship between cousins. There may be another way to test the unknown relationship through other first-degree relatives. Please call our friendly client support. We are more than happy to assist you with options on testing with those that are available to test. It may be easier to talk about specific details in your case over the phone. Call us at 1-888-404-GENE, Monday-Friday 9AM-6PM ET. Thank you for your comment!
Megan says
My boyfriend did a home DNA test, it said probability 0% but quite a few allies matched and in the PI part there are several number and only seven that are 0.00, and eight have numbers. My boyfriend’s brother lives with him in which they have different father, is it possible that the test showed probability 0% because he tested his bother instead? It looks like there is some type of relation between my the tested individual and my daughter. I wasn’t present at the time, but it seems that this is an attempt to not pay child support.
Meisha says
Megan,
I do apologize for the belated response. With the personal peace of mind tests we do not have a disinterested third party witness there during the collection; therefore we have no way to confirm whom the samples were collected from. We always encourage our customers to be present and witness all of the samples being collected, placed in the specimen envelopes, as well as accompanying the samples directly to the mailing facility. This will ensure everyone is secure in the fact that the correct samples were sent off.
As humans we share some common DNA so you will often see some DNA markers matching between the test participants. The relationship index must be a match for every DNA marker tested for there to be a relationship between the participants.
If you are not positive that the samples we tested were for the correct participants we do have a legal test we can recommend to you. Legal DNA testing requires that all parties go to a designated collection facility so that a Chain of Custody can be established. Chain of Custody is the process used to maintain and document the chronological history of the samples (who has control of the samples at what time). At the collection facility, you will be asked to sign consent papers, designate an address where you want the results sent, and provide personal information such as photo identification. This process prevents anyone from being able to provide incorrect samples.
Olivia says
My husband took a swab test in Dec as well as the mother and child. We are unclear about results. Mother, son, and alleged father had professionals take the swab and the ID’s were varified and copied as well. Father is in one state mom and child in different state. The test states that he is 99.99% the father however out of 15 only 9 Y’s matched between father and son. I thought a son and the father both Y line were identical. By reading the numbers the son got some of his X from his mother either line and some from the father X line or the Y for the match. If the son got his X from father and Y from mother Could this be explained further, please. These are the ones where the Y doesn’t match for father and son but the X will in some places.
Example: Mother Son Father
TH0 7 9.3 7 9.3 7 9
D5S818 12 13 11 12 10 11
D16S539 10 12 10 11 11 13
Pentax D 10 13 9 10 9 –
FGA 22 – 22 – 22 26
D19S433 13 14 12 14 12 13
Amelogenin X X X Y X Y
Meisha says
The results can be a little difficult to read and understand but here are a few examples that may help:
If it reads: is excluded as the biological, the Combined Parentage Index (CPI) is 0 and has a 0% of probability, this means that he cannot be the father because the analysis shows that they do not share a paternity relationship.
Or if it reads: is not excluded as the biological father, the Combined Parentage Index (CPI) would be 100 or higher and is greater than 99%, this means that he is considered to be the father because the analysis shows that they share a paternity relationship.
The DNA profiles in paternity testing consist of DNA markers (usually 15) that are used to determine if there is a biological match, the same “codis†markers used by the FBI for DNA evidence. Each Marker location shows 2 alleles (the numbers listed under each participant in the example below). Everyone receives one number from their biological mother and one number from their biological father. These markers are analyzed to verify matches between the alleged father and the child. If the markers between the alleged father and child match they are given a Parentage Index number that indicates how common that marker is among the population. If the marker is rare the number will be higher, if the marker is common the number will be lower. These numbers calculate to give the probability of paternity. The probability of paternity for inclusions must be higher than 99%. The probability of paternity for exclusions will show as 0%.
The “X” and “X , Y” shows gender. When there is a single “X” the gender is female, “X , Y” is male.

Cassie says
So my boyfriend recently found out his kids mom is pregnant and he might possibly be the father, however we are also thinking it was a set up because it could very well be my boyfriends fathers child too. Sounds crazy I know but his kids mom and his dad have been living together for many years now and very much act like a couple. There is another guy who could be a possibility but my boyfriend and his dad are the main two guys. My question is what if his dad doesn’t get a DNA test done and only my boyfriend does? They share the same DNA since they are father and son. He could possibly be raising his sibling rather then his child. They don’t speak so talking about the situation is totally out of the question, which leaves us with many questions unanswered.
Meisha says
This is a fairly common question. People are extremely concerned that results will be incorrect if the two alleged fathers in the case are related. The possibility of this causing problems with the results of a paternity test is higher but not by a lot.
Two people who are father and son still have very unique DNA profiles. It is extremely unlikely that two people who are first degree relatives would match the same child at all the markers tested for paternity.
In these situations we usually recommend both alleged fathers, the child in question, and the mother of the child to all participate. If only one alleged father agrees we still recommend the biological mother, and our lab will need to know there is a second alleged father that is a relative to the first alleged father.
I hope this information helps. If you have any additional questions or concerns please feel free to contact us 888-404-4363 and we will be happy to assist you.
row says
Hey I had a question, that I couldn’t dint on the internet. I don’t know if I worded it wrong or what, but here’s my question.
Is there a possibility that the mothers genetics is dominate over the fathers genetics in a child? Where in a two person paternity test where is would be a low percentage like 0.1% for example. Would that be a possibility still that the appointed father is the father to the child? Even though the test said he is not the biological father? It was a paternity test for hair samples. If that makes a difference.
Meisha says
The DNA profiles in paternity testing consist of DNA markers (usually 15) that are used to determine if there is a biological match, the same “codis†markers used by the FBI for DNA evidence. Each Marker location shows 2 alleles. Everyone receives one number from their biological mother and one number from their biological father, and each person is made up of exactly 50% of their mothers and 50% of their fathers DNA. These markers are analyzed to verify matches between the alleged father and the child. If the markers between the alleged father and child match they are given a Parentage Index number that indicates how common that marker is among the population. If the marker is rare the number will be higher, if the marker is common the number will be lower. These numbers calculate to give the probability of paternity. The probability of paternity for inclusions must be higher than 99%. The probability of paternity for exclusions will show as 0%.
The accuracy for a DNA test using a cheek cell sample or a hair sample is the same. Your DNA does not change between DNA from a hair samples and a cheek cell. Therefore we are able to obtain the same result using a cheek cell as you would a hair sample.

Marc says
My results came back as not the father. Is it possible that there wasn’t enough saliva on the swab? Me and the mother both did swab together and she believes that the test is wrong. And also, I have a lot of dead skin on inside my cheeks from peeling with my teeth , would that affect it as well?
Meisha says
Hello Marc,
If there is not enough DNA on the samples or if they are contaminated then it is not possible to provide results for a test. In the event there is an issue with the samples we would ask for a recollection.
If the mother participated along with yourself and the child she would have strengthened the results. Based on the samples and information sent to us to test with the results we provide are 100% accurate.
If you feel as though you would want to do a second test to be sure we would recommend doing the legal test. Legal DNA testing requires that all parties go to a designated collection facility so that a Chain of Custody can be established. Chain of Custody is the process used to maintain and document the chronological history of the samples (who has control of the samples at what time). At the collection facility, you will be asked to sign consent papers, designate an address where you want the results sent, and provide personal information such as photo identification. This process prevents anyone from being able to provide incorrect samples.

I did a paternity test with the alleged father and he got 10 out of 15 markers I know I wasn’t with anyone should I do a test including my self
Meisha says
Good afternoon Crystal,
The DNA profiles in paternity testing consist of DNA markers (usually 15) that are used to determine if there is a biological match, the same “codis†markers used by the FBI for DNA evidence. Each Marker location shows 2 alleles. Everyone receives one number from their biological mother and one number from their biological father.

If the markers between the alleged father and child match they are given a Parentage Index number that indicates how common that marker is among the population. If the marker is rare the number will be higher, if the marker is common the number will be lower. These numbers calculate to give the probability of paternity. The probability of paternity for inclusions must be higher than 99%. The probability of paternity for exclusions will show as 0%. If your report showed the alleged father is excluded as the biological father, doing a second test including the biological mother would not change the result.
We always encourage our customers to be present and witness all of the samples being collected, placed in the specimen envelopes, as well as accompanying the samples directly to the mailing facility. This will ensure everyone is secure in the fact that the correct samples were sent off.
The other option you have is to have a Legal DNA test. Legal DNA testing requires your samples to be collected by an uninterested third party. This is most easily accomplished by going to a collection facility. We have a database of DNA collection facilities nationwide, or we may also be able to assist in setting up the collection with a local doctor.
For a DNA test to be processed for legal purposes we also require identification for each person, including a birth certificate for anyone who is underage and does not have a current state or federal photo ID. A current picture of each participant is also required and is usually taken at the time of the collection appointment.
We also strongly recommend including a sample from the biological mother because there is a rare chance the results will come back inconclusive without her. Including the biological mother in the testing is optional. We can do the testing without her sample included, and we do provided conclusive results on a regular basis when only testing the alleged father and the child.
If you have any additional questions or concerns please feel free to contact us 888-404-4363 and we will be happy to assist you.
Mandy says
My current boyfriend took a DNA test and 15 of his marker match the 15 markers of the tested child. Mother was not included. Results were 99.98 that he was the father. But my question is his brother also had relations with the same girl (no the brothers are not twins) but is it possible the other brother could be the real father?
Meisha says
Good afternoon, Mandy.
This is a fairly common question. People are extremely concerned that results will be incorrect if the two alleged fathers in the case are related. The possibility of this causing problems with the results of a paternity test is higher but not by a lot.
Two people who are full brothers still have very unique DNA profiles. Half brothers would have even more separation since they only share one parent, and so on. It is extremely unlikely that two people who are only siblings would match the same child at all the markers tested for paternity, unless the siblings were identical twins.
As full brothers share more common DNA than two alleged fathers who are not related, it is always safe to do another test. In the event that two alleged brothers are full siblings we recommend doing a test with both of the alleged fathers, the child in question, and the biological mother. Testing all these participants will provide the strongest result for both tests.
I hope this information helps. If you have any additional questions or concerns please feel free to contact us 888-404-4363 and we will be happy to assist you.
Simone says
Hello,
I was just contacted by my money greedy son’s father. We had a test done on our son in Dec 2010 when the baby was a few weeks old. I knew my son was his but he had friends of his put doubts into his mind so he wanted a ‘peace of mind’ before he signed his birth certificate, which I had no problem with. The results were sent to him, so I never them. I do know my son is his though. He even signed the birth certificate shortly after. Today he messages me and after I refuse to agree on lowering his child support (He has not seen our son in almost 3 years) he then stated that he will be taking me for court ordered dna testing because “the test we used was recalled for being inaccurate”. I searched online and cound not find any info nor articles about this company’s paternity tests being recalled. Could you please shine some light on this for me? Thanks!
Meisha says
Hello Simone,
I am sorry to hear you are going through these difficulties, and we apologize for taking so long to respond. I can assure you that our kit has never been recalled, and we provide the most accurate testing available on the market today. We have worked extremely hard to put measures in place that prevent any mistakes from being made throughout the entire DNA testing process from beginning to end. This is why the accreditations we hold as a laboratory are so important.
Our goal is to provide an accurate, quality service to all of our customers. An extremely important part of the testing process is how the samples are handled and managed as they travel step by step through each stage of the testing. The strict standards and procedures we follow extend to every single part of the process from the moment the samples arrive at our laboratory to the release of the analysis report when the testing is completed.
If a judge has requested a court ordered DNA test the results will be the same as the report we provided as long as the same participants tested in both tests.
I hope this information helps. If you have any additional questions or concerns please feel free to contact us 888-404-4363 and we will be happy to assist you.

Nicole says
Hey,
My DNA test report states the “alleged father is not excluded as the biological father of the tested child” i know this means he most likey is the father due to the evidence at hand et, cpi and probabilty of paternity.
The thing is i was in my period and it was severly heavy when i was with the alleged father and when i was off my period i had intercourse with another man.
My son looks identical to the second man and looks nothing like or acts like the alleged father.
Is there any possible way one of the alleged fathers is a chimera?
Meisha says
Good afternoon Nicole,
We apologize that has taken so long to respond to your question on our website. Whenever circumstances exist that make one doubt the conclusion obtained from a “Personal†relationship test, it may be worth to consider a “Legal†test. The difference to a “Personal†test is that all samples are collected by a disinterested third party, rather than by the participants themselves, and this guarantees the maintenance of a chain-of-custody for the entire process, including the collection of the samples. Chimerism would not be expected to make an “Alleged Father†look like the father if in fact he is not the father.
You can read more information about Chimerism in this article, and the comments that follow:

Jordan says
Hi,
I had a non-invasive prenatal test done with only one alleged father and he matched all 14 DNA genetic markers. The company said they do not go by probability but my exclusion? I couldn’t get the other alleged father because he refused to participate. What are the chances that the other man could be the father? Please help
Meisha says
Thank you for contacting Identigene. We cannot speak for other companies or labs, but here are a few examples that may help:
If it reads: is excluded as the biological, the Combined Parentage Index (CPI) is 0 and has a 0% of probability, this means that he cannot be the father because the analysis shows that they do not share a paternity relationship.
Or if it reads: is not excluded as the biological father, the Combined Parentage Index (CPI) would be 100 or higher and is greater than 99%, this means that he is considered to be the father because the analysis shows that they share a paternity relationship.
The DNA profiles in paternity testing consist of DNA markers (usually 15) that are used to determine if there is a biological match, the same “codis†markers used by the FBI for DNA evidence. Each Marker location shows 2 alleles. Everyone receives one number from their biological mother and one number from their biological father. These markers are analyzed to verify matches between the alleged father and the child. If the markers between the alleged father and child match they are given a Parentage Index number that indicates how common that marker is among the population. If the marker is rare the number will be higher, if the marker is common the number will be lower. These numbers calculate to give the probability of paternity. The probability of paternity for inclusions must be higher than 99%.
The probability of paternity for exclusions will show as 0%.

Hello,
So I had a DNA test done for my daughter and her father. The test came back with 50%. Now my mouth was not swab, does this affect the results? I know i would be the other 50% as well.

A conclusive result is when a test is calculated with a probability of paternity of 0% or 99% – 99.99%, anything in between 0  99 % is inconclusive. So when the biological mother participants she helps to strengthen the test results.

Anna says
My father and I took a test it came back as 99.97% is this still accurate as 99.99%
Meisha says
Good afternoon Anna,
The tests we provide are 100% accurate based on the samples and information sent in to us to test with. The probability of paternity percentage is calculated using the DNA profiles from the alleged father and child in question. A percentage of 0.00% and a percentage between 99% – 99.99% is a conclusive result. Anything in between is inconclusive. So if the probability of paternity between your alleged father and yourself is 99.97%, that is a conclusive percentage. When a percentage is between 99% – 99.99% this means we do consider the alleged father to be the biological father of the child in question.
I hope this information helps. If you have any further questions or concerns please feel free to contact us at 888-404-4363.
Mandy says
My test said excluded as father but it was supposed to be an avuncular uncle test. Theres 15 markers (not counting the one xx and xy for my daughter) and it matched only 4 out of 15 of them. What might this mean?
Meisha says
Good afternoon Mandy,
If the participants sent in the samples under a paternity test (where the uncle’s samples were submitted as an alleged father) and we had no knowledge it was supposed to be an avuncular then the testing would have been completed as a paternity test. In paternity tests we do not test for any other type of relationship.
If you are needing the avuncular test it is $399 and results are typically available in 5 business days; this does depend on how your samples react to testing. You can order this test directly from us over the phone and we will send kit supplies out to each person for collection. To ensure that you select the correct test for your situation we recommend you contact us at your earliest convenience.
The test results for avuncular testing fall into one of four categories: strongly supported (conclusive), somewhat supported, inconclusive, or not supported.
I hope this information helps. If you have any additional questions or concerns, or are interested in an avuncular test please feel free to contact us 888-404-4363 and we will be happy to assist you.

Hi, i recently gotten my results back from my child alleged father.. my child was due to be born on aug 3rd but due to a c section cut he arrived july28th but aug 3rd is exactly 40wks frm the time the father and i 1st started having sex. about 7 out of 15 match up.. he was the only person i had been sexually active with since oct31/nov1 2013 until… please help me understand because the alleged father is very broken up about the whole ordeal.

Cheryl says
I recently had a sibling test done to determine a common father amongst myself and my 3 other siblings. The results came back and the Full Sibling percentages are 99.9999 (example) and the half sibling percentages came back at 99.99 (example). What does this mean? Does the higher percentage determine full sibling?
Meisha says
We would be more than happy to assist you with the calculations on your test report. This would be easiest to address by calling us at 888-404-4363 and talking to a dna consultant over the phone. This way we will be able to answer questions about your report specifically, including questions about the percentages from your sibling test. We look forward to hearing from you.
Lakin says
Hi, my brother just got the results of his test and the mother didn’t take her dna sample but it says 0% and 0 But 11 out of the 21 had the same/ one number correct…I was just wondering could he still possibly be the father? And do you think it would be a waste of money and time to take another test but with using mothers dna too? thanks

I was married to a man that was married before we met and had to kids with this first wife. They divorced and we got together and had a daughter. now one of his kids are asking if i would let my daughter take a dna test to see if they are full sister, would a dna test come back that or do they need the father to take one. as the daughter of the first marrage doesnt talk to her dad.?
Leslie Bryant says
Thank you for contacting Identigene. We do offer a sibling test. Since everyone gets half of their DNA from the mother and half from father, we can determine the type of relationship for siblings:
– Full vs. Half
– Full vs. unrelated
– Half vs. unrelated
The Sibling DNA test is $399, and results are typically available in 5 business days; this does depend on how your samples react to testing. You can order this test directly from us over the phone and we will send kit supplies out to each person for collection. To ensure that you select the correct test for your situation we recommend you contact us at your earliest convenience.
The test results for siblings will be one of four categories: strongly supported (conclusive), somewhat supported, inconclusive or not supported. We do strongly recommend including a sample from the biological mother (both mothers when relevant). There is a greater chance that the results will come back inconclusive without her.
I hope this information helps. If you have any additional questions or concerns, or are interested in a Sibling test please feel free to contact us 1-888-404-4363 Monday through Friday 9 a.m. to 6 p.m. and we will be happy to assist you.
meaky k. says
hello i read a dna result that said 1464 times more likely than any other unrelated person what does that mean? what percentage is that?
Meisha says
Good afternoon,
The combined relationship index means that the alleged father is that many more times likely to be the father compared to an untested, unrelated man. We would be more than happy to assist you with further explanation on your test results. This would be easiest to address by calling us at 888-404-4363 and talking to a dna consultant over the phone.

Hi. I would like to ask. If the John Doe is execluded as the biological father of Larry Doe, does it mean that John cannot be Larry’s father legally even though they are not related? As in, if John still wants to be Larry’s father, is it possible?
Leslie Bryant says
Thank you for contacting Identigene. If the alleged father was excluded as the biological father. He would have to legally adopt the child to have “legal” rights, however being a father is more than just biology. And what that looks like is different for each family.

Hello I’m going through something right now with my child father doing a home DNAhe said he did with our daughter 3 weeks ago he said he did the test without me there and the results came back 0% I’m not understandingthis because webeen together almost 7 years now had our first daughter almost 1 year ago next month n he really bugging out thinking our daughter is not his he even left her n neglect her he is the only man I’ve been with no other party now he even had help with his little sister setting up the test wich was brought to my attention
Pleas help me I’m file for a DNA Court order yes
Leslie Bryant says
Thank you for contacting Identigene. It sounds to me like you will need a Legal DNA test. This testing requires that all parties go to a designated collection facility so that a Chain of Custody can be established. Chain of Custody is the process used to maintain and document the chronological history of the samples (who has control of the samples at what time). At the collection facility, you will be asked to sign consent papers, designate an address where you want the results sent, and provide personal information such as photo identification. This process prevents anyone from being able to provide incorrect samples. This would be the only way both parties can be sure the test was done accurately.
Personal DNA testing is not legally admissible in court, because the DNA samples are collected in the privacy of your own home. There is no way to confirm whom the samples were collected from or if they were purposely contaminated. Which might of been the problem in the collection your boyfriend did.

I had a DNA test in 1997 for my daughter it was done through Identigene it came back 99.984% that my daughters father was her dad since my DNA is in the system already do they have a test for people that are adopted I was adopted and I know my biological mom but know nothing about my dad I wonder if any of his family DNA is in the data base
Leslie Bryant says
Thank you for contacting Identigene. Unfortunately, with privacy regulations and HIPPA requirements, we are not able to test anyone without their consent, or share any tested information. Our testing is limited to the samples provided to us and are only used for DNA identification and comparison in that single test alone. Even if a person was tested before the comparison process is limited to only the DNA test they were associated with.

Rob McCourt says
Please help.
20 years ago, I had a dna test and the results came back and said that I was 67 thousand times more likely to be the childs father. Now at that time we had a family member in medical science who said it wasn’t enough and that dna tests would typically says 69 million times more likely. Now to add the child support agency at that time were demanding money from me but after the dna test i received a letter from csa saying that I owed them nothing. Now being 20 years ago I have no records of any of this, But the problem is now this young girl is trying to find me through facebook and I don’t know what to say or do. Should I arrange another test or leave well alone. I’m confused now.
Leslie Bryant says
Thank you for contacting Identigene. DNA testing, as a science, has changed significantly over the past 20 years. What would of been inconclusive back then could be easily seen and conclusive now with advancements in technology. If you are wanting to understand if this person could be your child, I would recommend doing the test again with Identigene. Our 100% accurate results will give you the answers you are looking for. The most ideal would be a test that included the alleged father, child and mother.

Joe says
How important is the race/ethnicity description?
I am half Hispanic and half Caucasian what should I Identify as on the test question and how does this effect the results?
Meisha says
In cases where we cannot exclude a man from paternity, we provide a likelihood of paternity using allele frequency statistics derived from each of the major populations. At each system where the child and alleged parent share an allele, we calculate the likelihood that they share that allele because they are parent and child vs. whether that allele would be shared if the child’s parent is an untested person from the same racial population. Therefore, by providing the ethnicity of the alleged parent, we know what racial population to use as the random population to which the comparison should be made.
For example, if the child and alleged father share an allele 16 in common, we calculate the likelihood of that occurring if he were the biological father, vs. seeing the sharing of the 16 if a random person in that population were the father. So if allele 16 were very, very rare in the Caucasian population, then it is much more likely that they share the 16 because they are father and son, than if they share the 16 in common if a random person in the Caucasian population were the father of the child. Conversely, if allele 16 is very common, then it might be equally likely that they share the 16 in common because they are father/son than if the child’s father is a random person in the population.
In cases where the alleged parent is of mixed race, we use the most conservative allele frequency value from all races, which provides the most conservative paternity statistic.
Joe says
Thank you for your answer.
There was not a mixed race answer when filling out the test so I selected Hispanic.
Will this materially affect my results?
Is there a way I could make a note on the online invoice to let the tester know?
Meisha says
There should be an “other” option on your sample envelope with an empty box beside it. You can check “other” and write in your ethnicities in the box provided. If the lab has both ethnicities they can take both into consideration while testing. The information on the sample envelopes is the information we go off of for your case. We request the information be provided during online payment to ensure the information we are receiving is correct for your case.
Christian says
I did a test with you all. I’m confused about it though. Most of the numbers on the test of my child and the man I had the test done with are the same or very close. But it says he’s not the father. Why is that ? When I haven’t been anyone but him.
Meisha says
We always encourage our customers to be present and witness all of the samples being collected, placed in the specimen envelopes, as well as accompanying the samples directly to the mailing facility. This will ensure everyone is secure in the fact that the correct samples were sent off. With personal peace of mind tests we do not have a disinterested third party witness to ensure the correct participants DNA is being sent in to test with. Based on the samples and information we receive to test with the results are 100% accurate.
The DNA profiles in paternity testing consist of DNA markers (usually 15) that are used to determine if there is a biological match, the same “codis†markers used by the FBI for DNA evidence. Each Marker location shows 2 alleles. Everyone receives one number from their biological mother and one number from their biological father. These markers are analyzed to verify matches between the alleged father and the child. If the markers between the alleged father and child match they are given a Parentage Index number that indicates how common that marker is among the population. If the marker is rare the number will be higher, if the marker is common the number will be lower. These numbers calculate to give the probability of paternity. The probability of paternity for inclusions must be higher than 99%. The probability of paternity for exclusions will show as 0%.
In most cases you will see some matching alleles and that is because as humans we all share common DNA. In general, the possible father and child must match at every location (each genetic system we test). If a possible father does not match the child, then we can be 100% certain he is not the biological father of the child.

Tiffany says
HELLO MY BROTHER AND I JUST HAD DNA TESTING DONE my brothers results had 26 different tested alleles I only had 20 with higher PI what does this mean
Meisha says
Hello Tiffany,
We would be more than happy to assist you with understanding why some tests have more or less DNA markers tested than others, as well as any other questions you may have about your specific report. This would be easiest to address by calling us at 888-404-4363 and talking to a DNA consultant over the phone. We look forward to hearing from you.
Jennifer says
I did the home dna test with my boyfriend and baby, the results showed probablity of Relalionship: 0.00%,My daughter match 13 of the 15 with him, I understand that if 3 or more mismatches, the result is found to be exclusive or not related, But they have just 2 mismatches. I don’t really understand why the results are negative.
Meisha says

Ricardo Harry says
I have an alleged sister my dad admits to having unprotected sex with her mother one time when they were younger but he says that he is not her father and he refused to take a paternity test.My question is if my alleged sister and I took a paternity test would we get accurate results which will prove we are related.
Meisha says
Hello Ricardo,
We do offer a sibling test. Since everyone gets half of their DNA from the mother and half from father, we can determine the type of relationship for siblings:
– Full vs. Half
– Full vs. unrelated
– Half vs. unrelated
The Sibling DNA test is $399, and results are typically available in 5 business days; this does depend on how your samples react to testing. You can order this test directly from us over the phone and we will send kit supplies out to each person for collection. To ensure that you select the correct test for your situation we recommend you contact us at your earliest convenience.
The test results for siblings will be one of four categories: strongly supported (conclusive), somewhat supported, inconclusive or not supported. We do strongly recommend including a sample from the biological mother (both mothers when relevant). There is a greater chance that the results will come back inconclusive without her. The results will always be 100% accurate based on the samples and information sent to us to test with.
I hope this information helps. If you have any additional questions or concerns, or are interested in a Sibling test please feel free to contact us 888-404-4363 and we will be happy to assist you.
Kk says
I had a DNA test done and the results came saying the alleged father was 93.8% excluded. Does that mean he is not the father ? It wasn’t 99.9% so I’m confuse as to whether what the answer is.
Meisha says
Good afternoon KK,
The results can be a little difficult to read and understand but here are a few examples that may help:
ÂÂ
If it reads: is excluded as the biological, the Combined Parentage Index (CPI) is 0 and has a 0% of probability, this means that he cannot be the father because the analysis shows that they do not share a paternity relationship.
ÂÂ
Or if it reads: is not excluded as the biological father, the Combined Parentage Index (CPI) would be 100 or higher and is greater than 99%, this means that he is considered to be the father because the analysis shows that they share a paternity relationship.
The DNA profiles in paternity testing consist of DNA markers (usually 15) that are used to determine if there is a biological match, the same “codis†markers used by the FBI for DNA evidence.

pete says
The results for my test show a Combined Relationship Index: XX,XXX to 1, Seems like a very high ratio. However, this is not CPI, Combined Parentage Index, correct? What is the difference? And, what does this CRI ratio tell me?
Meisha says
Good afternoon Pete,
There is no difference in combined relationship index (CRI) and combined paternity index (CPI). The CPI is how many more times likely the tested alleged father is to be the biological father compared to an untested, unrelated man. The ration is xx,xxx to 1 as there is only 1 possibility of someone being the father. The higher the number means the stronger the results.

chris says
Make up your mind! Is inconclusive under 99.99%, or under 99%? All of you paternity testing facilities contradict yourselves constantly! Also, motherless tests shouldn’t even be done! The only matches that are for sure in a motherless test are when the child and alleged father have 2 exact numbers for a specific loci, or the child and alleged father have 1 exact number at a specific loci. All others that appear to match C and AF at a specific loci with 1 out of 2 numbers matching could be a DEFINITE MISMATCH! But this is a multibillion dollar a year scam, and none of you scumbags will admit to the many other problems that are assumed as well! Good luck on judgement day! Dress appropriately cuz I hear its pretty hot down there!
Meisha says
Hello Chris,
I’m sorry if you’ve experienced any confusion about “conclusive†vs. “inconclusive†tests.
The result for any “positive†paternity test is expressed as a probability, but it’s a very strong probability based on considerable scientific analysis and complex statistical models. Probabilities of 99% or greater are so reliable that such results are routinely accepted by courts, governments, and police forces worldwide as the standard for answering paternity questions.
In general, a 0% probability means “definitely not the father†and anything above 99.0% means “very likely to be the father.†Anything in between (greater than 0% but less than 99.0%) is usually considered inconclusive. In the U.S., most courts will accept 99.0% or above as proof of a paternity relationship (a notable exception is for immigration cases, which requires a 99.5% or higher probability).
You are correct that testing without mother could theoretically lead to a “false positive†result, which is why we test the mother for free and strongly recommend including the mother whenever possible (see http://dnatesting.com/including-the-mother/). Rest assured, however, that “false positives†are extremely rare, especially in cases where the father and child share multiple matches with uncommon alleles. Our laboratory analysts look deeply into each case and, if there’s any evidence that suggests even the possibility of a false positive, we request the mother’s samples before releasing a result.
It might help to look at it this way: a typical paternity test includes about 15 genetic markers (a.k.a. “loci” or “allelesâ€Â). Any two people in the world might randomly match for a handful of these markers and still not be related. If they have matching markers at ALL locations, it’s more likely the two are related. Probability in a paternity test depends not only on a match, but on the strength of the match (the more uncommon the number at a particular marker, the stronger the match). So, if two individuals match at all locations, and they have one (or possibly many) strong matches, it’s very strong evidence that they share a parent-child relationship–even if the mother isn’t included in the test. (By the way, there are many studies and data available about paternity probability and calculations; just search Amazon.com for “human genetics textbook†to find some of the best.)
If you feel your test results are not accurate because the mother was not included, please contact us and we’ll happily add the child’s biological mother to the test. (Please note that we test the mother for free when she’s included in the test upfront or within 30 days of receiving your results. If your case is older than 30 days, there may be a charge to include the mother and rerun the analysis.)
luz says
I did a dna and it came out 99.95 and that 5 it make the diffent in dna of paternity 99.95 is means they r siblings
Now, this is to any human. How similar are you to your parents? Or to your brothers or sisters? This is where the 99.95% comes in.You are 99.95% the same as your sibling.
explain that if the child n the father come 99.95% that means they r sibling a need a gd expliation

Stephan says
I got the same result on my home DNA text and I took it twice and still got 99.95 and a mutation was found and I suspected the mother of the child was sleeping with my father could that mean that he is the father ?
Identigene says
Most likely not.
Terry says
I had a DNA test done with Ancestry.com last year, the results came back I was 58% English, no Italian or Portuguese. My father is Italian & Portuguese. My mother is English and Swedish. My interest was peaked so I had a Y-DNATest done with ftdna and it said my fathers side was English and Norwegian.
When I was 14 my parents divorced. My two older brothers and my fraternal twin brother stayed mith my father. A few months after my mother left my father told all 4 of us, during a depressing time for him, my twin brother and I were not his children. I was of course shocked, hurt and confused. I never could find the right time to ask my mother about it until a few years after my father died, about 14 years later. She told me he was just upset and that he was indeed my father. I was 28 then.
My twin brother and I are now 51 and we want the know. Is the Y-DNA test the best test for us to have done? I think I can get all of us 4 boys tested. I really Dont want to get my mother involved unless I know for sure my older 2 brothers are only 1/2 brothers. What are my chances of getting conclusive results?
Meisha says
Good afternoon Terry,
If you are wanting to see if your brothers are your half siblings or full we would recommend a siblingship test. The Sibling DNA test is $399, and results are typically available in 5 business days; this does depend on how your samples react to testing. You can order this test directly from us over the phone and we will send kit supplies out to each person for collection. To ensure that you select the correct test for your situation we recommend you contact us at your earliest convenience.

Mark says
I have a 5 year old son that I have always wondered if he was mine. I took a home DNA test without the mother because she want agree to a test. When doing the test I accidentally placed my samples on top of the child’s samples before they were dry. Could this have contaminated them? Also my results came back 99.97% not excluded. I understand this means I am the father but I thought the results have to be 99.99% or 0%. The child looks nor acts anything like me and I was not around at the time of his conception which is why I’ve always wondered if he was mine. Could the fact that the mother wasn’t tested caused a false positive?
Meisha says
Hello Mark,
We do strongly recommend including a sample from the biological mother because there is a rare chance the results will come back inconclusive without her. Including the biological mother in the testing is optional. We can do the testing without her sample included, and we do provide conclusive results on a regular basis when only testing the alleged father and the child. So if the mother was needed for this test we would have contacted you to see if she was available to participate. This web link will provide you with additional information about why the biological mother is sometimes needed to complete testing: http://dnatesting.com/including-the-mother/.
Our lab does check for any issues with the samples sent in to us for testing. We detect if there are two different DNA samples on the same sample swab, as it will show two different DNA profiles. If your samples had contaminated the child’s samples we would have placed your case on hold and asked for a recollection, it is not possible to produce results with contaminated samples.
As far as the probability of paternity on your result, 99.97% is a conclusive percentage. When a percentage is 0% or 99.0%-99.99% it is a conclusive answer, anything in-between is not conclusive. If the percentage came back in between 0-99% that is when we ask for the biological mother to participate in the testing to strengthen the results.
I hope this information helps. If you have any further questions or concerns please feel free to contact us at 888-404-4363 and a DNA consultant will be happy to assist you.
Darlene says
I had a DNA test done for my daughter and her father. D16S539 was a mismatch and all other numbers match. The probability of paternity is 97%. They suggest that I be tested to be conclusive. My daughter have 5 single digit numbers, will those numbers automatically go to me the mother. What is the possibility of mutation occurring at the D16S539?
Meisha says

Ariella says
Hi so my alleged father passed away so I did a paternity test with his mother and the results came back as the probability of relatedness is 3.1% and the likelihood that she is my grandmother is 32 to 1. Does this mean she is in fact my grandmother because it didn’t come back 0%?

Anna says
Hi I tested only one of two possible fathers. He matched 8/24 markers. He was therefore excluded as fsther.
I have also had an uncle relationship test done between the child and this man to try to rule out him being a chimera. This came back at a possibility of 0.49% which is an exclusion. The child looks so much like him.
Is this enough to rule him out as the father?
The child looks nothing like the other man and the therefore assumed biological father. Is this even possible!
Meisha says
Hi Anna,
We certainly understand your question–and it’s a good one. Rest assured that, even though people may appear to “look†related (well call this “phenotypeâ€Â), the DNA analysis of their genetic profiles (we call this “genotypeâ€Â) is much more reliable. In fact, many people look alike but are not related, for example, friends who are mistaken for sisters or brothers, or “doubles†for actors in movies. Sometimes people who are related, like sisters or brothers, often don’t look alike–one sibling is “light†and the other “dark†in hair color, eye color, or skin color, for example. Both situations are very common, which is why DNA testing is so valuable–it gets past how we look (“phenotypeâ€Â) to analyze our actual genetic biology (“genotypeâ€Â).
If the biological father was excluded as you described, he would be definitely excluded from our point of view. Genetic chimerism (or “congenital chimerismâ€Â) is extremely rare (think “one in a million”) and, when it does exist, it’s indicated by different genetic profiles from the same person. If you’ve completed two tests with this individual and his genetic profile was the same on each test, that’s evidence that strongly suggests he isn’t a chimera.
Your best option is to test the other possible father–a strong match that includes him as the biological father would rule out all doubt about the other man. Please let us know if we can help you arrange for testing.
JPRamos says
i doubt about this child. because the child is really looked like this uncle. i saw his uncle’s picture when he was young probably same age as the child now. and surprisingly they are really look a like. can i determine if im the father of this child with only me and the child’s DNA to be sent. because im sure that this child’s uncle and the mother of the child will not participate. what is the % probability that the result will be concrete?
Meisha says
Good afternoon,
We can perform a DNA test with just an alleged father and child, based on the samples and DNA sent to us your results will be 100% accurate. However, when there are two alleged fathers with a first degree relationship the result can provide a false positive (if the alleged fathers are full brothers for example). If the alleged fathers are half siblings then the chances of a false positive or a lot less. Our recommendation would be to have both alleged fathers, the child in question, and the mother of the child all participate for your absolute strongest result. Otherwise, our lab would need to be informed before any testing is done that the alleged fathers are related and what the relationship is.
I hope this information helps. If you have any further questions or concerns please call us at 888-404-4363 and we will be happy to assist you.
Sam says
Hi
I have two children I would like to carry out a sibling test for.
They have the same mother and from previous parernity test results I assume the same father.
How accurate are the sibling tests?
Would half siblings show as full sisters by mistake?
It is not possible to test the father involved.
Thank you

We do offer a sibling test. Since everyone gets half of their DNA from the mother and half from father, we can determine the type of relationship for siblings:

Melony says
My husband had a DNA test performed in 2003 that stated he could not be excluded as the biological father but only 13 loci or genetic markers were tested. I have read that at least 15 to 16 loci or genetic markers should be tested for an accurate result. Is this true and if so should we have another test performed?
Meisha says
Good afternoon Melony,
The amount of genetic markers tested is determined by how many it takes to achieve a conclusive result. We usually test between 15-17, but again it depends on the DNA profiles being tested. If another test is done between the same participants the results will come back the exact same.
We would be more than happy to review your case and test results to help you better understand the information. Please feel free to give us a call at 888-404-4363 and a DNA consultant will assist you with any questions or concerns you may have.
Austin says
I took a DNA test for my daughter with her biological mother because I thought I was the father of the little girl but my family did not. Turns out I am not the father and the test came back 0% chance and it broke my heart. My girlfriend claims she was sexually assaulted by two twins at a party right before she got pregnant. One of the twins took a test and it came back as 66% chance and I do not understand what that means, As time goes by I am starting to think my girlfriend has cheated on me with somebody else and created what was suppose to be my daughter I need help I don’t understand what that 66% chance can mean
Meisha says
Good afternoon Austin,
If the test was done through Identigene, a result with a probability of paternity of 66% would mean that is an inconclusive results. A conclusive results is 0% or 99%-99.99%, anything in between is not conclusive. Below is a link that can provide you more information about inconclusive results.
If you have any other questions or concerns, or would like to discuss the results with a DNA consultant, please give us a call at 888-404-4363.

Ekala says
Hello I was just wounding if 99.99999998% is a percentage? And on the table Down the bottom it says probability of paternity = 99.999999981739400% I was wounding what it means?
Identigene says
Yes, it is a percentage of certainty. So it’s based on a scale of 100%.
Erin says
I’m the mother and personally took the samples from my son and his alleged father. On the results, 3 of my(mother) results returned with only one number and the relationship index read 0….this concerns me that my results made this a faulty test. Should I request to retest? Is it possible that my tests were contaminated or I didn’t do my own swabs correctly? Also, is it possible to have 2 or 3 relationship indexes read as 0 and the alleged father still be the biological father?
Identigene says
Hi, Erin. I apologize for the delayed response. If an alleged father and child have even one “parentage index” of 0.0, then the conclusion is that there is no parental relationship. As to your own test results, if you still have not received the answers you’re looking for, please contact us at 888-404-4363 during business hours. Thanks.
Jeff says
On old girlfriend claims her daughter is mine. But I have reservations. A few things I have read says she is not. My eyes are green, the mothers eyes are blue. The daughters eyes are brown. The mothers blood type is A- I am A+ and the daughter is O-. Also everyone of my kids have a few features that she doesn’t. A cleft in the chin and large eye teeth. With all of those difference. Is it possible she is mine?
Identigene says
Hi, Jeff. Eye color and the other physical traits you mentioned are not good indicators of relationship due to a wide number of factors. Blood type is a better indicator. However, that being said, the absolute foolproof way to determine paternity is through DNA testing. It’s very easy to test mom, child and potential dad using cheek swabs from an IDENTIGENE paternity test kit.
Marie roberts says
Already had DNA test 14 yrs a go .Recently child support in Britain changed .Hes disputing Paternity again after paying 14 yrs .It was 99.99 % .Its so wrong as we’ve been told we have to do another again .To what I know DNA won’t change just cause she’s older ?
Identigene says
Hi, Marie. Our DNA does not change as we get older. If the court mandates it, however, you may need to do another test. I suggest you contact an attorney for guidance. Good luck!
Cathy says
I got a DNA test done 20 years ago on the father n daughter it came back 86% what does this mean father said she is not my kid cat because of testing was not 100% only father n dougher was tested
Identigene says
Hi, Cathy. We recommend that you, your child, the alleged father and any other potential fathers be retested. It is especially important that you be tested as well this time.
Kalyn says
I sent in dna samples. Come to find out the potential father of my child did not swab his cheeks like he was supposed too. He said he swabbed his cheek with one, under his tongue with another swob and inside his bottom lip with the other swob. Will the dna test still be able to be done??
Identigene says
Hi, Kalyn! If there are any issues with the collected samples that would prevent an accurate DNA test, you will be contacted.
micaela says
I used the paternity test. The results came back as not the father but not all of the numbers were there. There was a big chunk of numbers missing from the alleged fathers test results and some missing from my son’s. And it came back as not the father. Could he still be the father even though the test said not the father?
Identigene says
Hi, Micaela! I suggest you contact the company from which you purchased the test and have them go over your results with you.
Identigene says
Hi! If you have any questions at all about the results of your test, I suggest you call and speak to a representative personally. They are experts and will be able to help.
Tiffany says
We just received the results from our DNA paternity test. The probability of relationship is 99.99%, and the Combined Relationship Index is 39.720 to 1 likely than if an untested, unrelated Hispanic man is the biological father. What does the Relationship Index mean in this instance? Why is it only being compared to Hispanic men? (Yes we put down Hispanic as the ethnicity for the potential father that was tested). The other potential father that was not tested is White.
Tiffany says
39,720 to 1

Fred says
What does a negative -12.31, D21S11 means ? out of 15, all 14 matches except this one that makes the CPI a negative number?
D21S11 is: Child is 30.31 and the father is only 18 with a PI of negative -12.31?
the results came saying the alleged father was not excluded.
Please clarify as how this negative number affects the result?
Thanks and regards

cherri dickson says
I did a DNA test with my fraternal twin to see if we have the same mother, but the test show that we are not brother and sister,dose that mean we don’t have the same mother,our mom died so we don’t have her DNA.I just wanted to know if we had the same mom,what do I need to do…

Hi, Cherri. We suggest you contact one of our friendly, knowledgeable client support specialists at 888-404-4363. They’ll be able to pull up your case and help you interpret the results you were given.
J says
I want a paternity test if it wants further dna/dna from another might be father would you have to pay again and can it say yes there is 2 fathers or will it just say that one is the father I know it sounds silly and you might not understand what im asking
Identigene says
Hi! The IDENTIGENE Paternity Test kit can be purchased at Walmart, Rite Aid and CVS, as well as right here on our site. Each kit includes enough cheek swabs to test three people. Although we recommend using one of those sets of swabs to test the mother, you can instead use the swabs to test the child + two potential fathers. When you are testing one child, there can be only one possible father. Hope this helps!
travis says
Do i receive a phone call with my results?
cengerman says
Hi, Travis. You can use the Results Login at DNAtesting.com to view, download, and print your paternity (and other test) results. You may also get results over the phone or request a mailed hard copy by calling us at 1-(888)404-4363, Monday- Friday, 9 a.m.- 6 p.m. ET.
Tiffany says
Hello I have a question my twin brother and I had a DNA done my father was indeed my dad but our results were different they tested more genes on my brothers dna does this mean he matches my father more
cengerman says
Hi, Tiffany. What a great question! The only way for your results to be exactly the same as your twin’s would be if you were identical. And since you’re fraternal, there will be variances between you. If the lab tested more markers on your brother’s test, that may have been done simply to get a more conclusive result on the test; it doesn’t mean he “matches your father more.” Both of you got 50% of your DNA from mom and 50% from dad. Hope this helps!
Bek says
I did two different tests. Both times I tested myself, my daughter, and a potential father. Both came back 0%. I just found out that my daughter has and had thrush for both tests. Would that cause the test to come back negative?
cengerman says
Hi, Bek! The only way thrush might affect DNA collection is that it could degrade the sample. If this were the case, the lab would have contacted you to ask for a recollection. In short, you would not have been given a 0% result due to the thrush.
Sonia says
so a test result of father not excluded with a CPI 64.216 and a probability of 99.99% does NOT mean that this person is actually the father of the child?
cengerman says
Hi, Sonia! When a father is not excluded with a probability of 99.99%, this means that he is considered to be the father because the analysis shows a shared paternity relationship. If you need additional help with understanding your test results, please contact our Client Support Center at 888-404-4363 during business hours.
curiousjanedoe says
My boyfriend and I took a test on a child from his previous relationship to find out if that is his child but we didn’t know until today when we got online that he could have set up and account or included his email address and a pin for results but we have mailed everything off already. So are we still able to get the results so we will know? Because we don’t wont to lose money behind this and don’t know when we will be able to get the kid again if another test is needed this was a lucky shot for us so I pray we can still call in with the info we put on the envelope for results.

Hi! Just give us a call at 888-404-4363 and one of our Client Support Representatives can help you, OK? No worries!
Basem Galal says
In a paternity test , combined relationship index is 26,656 to 1 and probability relationship is 99.99% and conclusion said ” not excluded as the biological father” how come although you said CRI must be 100 or larger to be the father. Please explain
IDENTIGENE says
Hi, Basem. In order to declare that someone is the father with 100% certainty, we would need to test the entire genome of an individual: absolutely all their DNA. This would be impractical and impossibly expensive to do. The PI (parentage index) is a calculated value generated for a single genetic marker or locus (chromosomal location or site of DNA ) and is associated with the statistical strength or weight of that locus in favor of or against parentage. In order for the potential father to be “not excluded” (considered the father), the combination of these PI numbers (CPI) must be 100 or more. Even if the CPI is well over 100, we would still only give a 99.9% probability, since not absolutely all genetic markers were tested. Hope this helps!
Basem Galal says
I’m asking about if combined relationship index is 26,656 to 1 & probability 99.99% is enough to make the man the father? Conclusion ” not excluded ” is right or false
IDENTIGENE says
Oh, I’m sorry, Basem. Our reports say that when a man tested is “not excluded,” that we consider him to be the biological father of the child, yes.
Basem Galal says
Please help me Doctor I know that ” not excluded” means the biological father i’ m asking about the number of combined relationship index 26,656 to 1 has a reference range to make the person father or not or it is not related to conclusion please reply ” i’ m not sure of the conclusion in my lab”
IDENTIGENE says
Hi, Basem. If you call one of our experts at 888-404-4363, they’ll be able to help explain results more easily by phone. Thanks!
Anonymous says
I have my results and on the testing the child and alleged father share a relationship index in all but 4 places and the results are saying that he is not the father and the probability of Relationship is 0.00%. How can they share a relationship Index in 13 places but not be related? Is it common to share a relationship index in some areas and not be related?
IDENTIGENE says
Hi! Yes, it is quite common to share a relationship index in some areas and not share a paternal relationship. Because 50% of DNA comes from mom and 50% of DNA comes from dad, each marker (location) tested should have one allele from each parent. If even just one of those markers doesn’t show the DNA from both parents, it can exclude the potential father from paternity. What we usually do in cases like that is test against the mother’s DNA too. Seeing as there were 4 places where the alleged father’s DNA was different, the lab gave a 0.00% relationship probability. Additionally, in all cases where a father is excluded, the lab retests to make sure. So you can be confident in the results you were given. If you want more info about your results, you are more than welcome to contact our experts in the Client Support Center at 888-404-4363. Hope this helps!
Anonymous says
ok so should I test against the mother or since there were 4 cases where it didn’t match, I can be sure that these results are true?
IDENTIGENE says
Usually they only ask for the mother’s DNA if the results are inconclusive. In this case, the mother’s DNA wouldn’t affect results or the lab would have asked for it. I’m sorry I wasn’t clearer on that point. You can absolutely trust the results you were given.
Adam says
Hi, when CRI is written 35,787 to 1 that means 35 only or 35 thousands?
IDENTIGENE says
Hi, Adam. It’s in thousands, in this case. What the number means is that if we tested 35,787 other men, you would be the only possibility as the biological father. The more relevant number is the probability of relationship percentage just underneath on the report. If you need more help analyzing results, our Client Support Team is happy to help you at 888-404-4363.
Bebe says
Hi hyd 5 years ago my friend I thought was the father took a paternity test with my child without me he had permission to do it and it came back 50% probability but now im thinking about my child father can it be that cause I didn’t do the test with him
IDENTIGENE says
Hi, Bebe!
Unless testing shows there is a probability of 99% or higher that we consider a man to be the biological father of a child or a 0% probability that he is, we consider results to be inconclusive. In cases like these the lab will often request that the mother provide a DNA sample if she didn’t the first time. It definitely strengthens results to include the mother’s DNA although it is most often not necessary. In your case, you may want to retest and include your sample as well. Each IDENTIGENE kit contains enough materials to test potential father, child, and mother. If you have more questions, feel free to contact our Client Support Center at 888-404-4363 (M-F, 9 AM to 5:30 PM Eastern Time). Hope this helps!
Bebe says
So can it be a probability that he are the father
IDENTIGENE says
With such limited information, Bebe, it’s impossible to say for sure. Again, I suggest you call us directly and gather as many details as you can before calling so that our experts can help you as much as possible.
Bebe says
Ok thanks
Krista says
My son and his ex gf did a paternity test with identigene, now the mother did not send in any samples, could this cause the test come back saying he is excluded as the father without her sample?
IDENTIGENE says
Hi, Krista. Participation of the mother is optional, although we always recommend she send hers in. The reason is there is a very small chance that results could be inconclusive without her DNA and the lab would have to ask her to provide a sample. If the lab results give a 0% probability of his being the father without having asked for the mother’s DNA to confirm those results, you can be confident that they are accurate.
Lynn G says
I tested my son and the alleged father. There are two possible fathers. But the alleged father drank a soda before swabbing then rinsed his mouth after reading he’s not to eat or drink anything for an hour before. The results came back, he is not the father. Should we test again?
IDENTIGENE says
Hi, Lynn. If his eating or drinking had affected the DNA, the lab would have detected it and asked for a new sample. In this case, it apparently had no effect since you were given conclusive results. You can trust the results you were given and don’t need to test again.
latasha says
hello
my question is this….I received my test results for the alleged father, child and I but it don’t say that all three samples was collected..only my son and I samples was showed as collected….
could this be a error for the results and the alleged father could actually be the biological father or it don’t matter and the results are conclusive?
IDENTIGENE says
Hi, Latasha. For questions about your own individual case, please contact our Client Support Team at 888-404-4363 (M-F, 9 AM to 5:30 PM Eastern). Thanks!
Rodrigo Torres says
Just got my results.
Results show: CPI 64,668 Probability of Paternity 99.998%.
Can I set aside my brother from being a potential father?
IDENTIGENE says
Hi! With that high probability, yes. Please call Client Support at 888-404-4363 so they can go over your test results with you and answer any remaining questions.
Kaitlyn D says
A full siblingship test was done on my two children. I am their biological mother and included my DNA sample with their test. Probability cam back with 99.98% that they are full siblings and their Combined Siblingship Index was over 7000. Just verifying it is a conclusive result and that they are definitely full siblings? Thank you!
IDENTIGENE says
Hi, Kaitlyn. Yes, ma’am. That is considered a conclusive result!
Lynn says
Hello, my sister baby father pass away. And his mother wanted a DNS test done. So the mother and the father of the deceased man took the test. The test came back that he is only 13% his child, or 13% of his Dna. My question is. Is it possible he is the father and the decease man father may not be his father after all? And it just match the decease man mother? The test was done 11 years ago and the question always boggled my mind.
IDENTIGENE says
Hi, Lynn. A test result of 13% relationship surprises us. We’ve never heard of such numbers given. Based on what you told us, you’re assuming the child’s deceased father really is the biological father. Are you sure about that? If so, it is possible that the deceased man’s father isn’t really his father. The bottom line is, with the limited amount of information you’ve given us, it’s difficult to give you a straight answer. Sorry!
Jennifer says
What if 2 children had 99.9 and one child was 99.7? Does this mean she is not his child?
IDENTIGENE says
Hi, Jennifer. No, not at all. Any results over 99%, we consider him to be the biological father.
Laporsha says
My boyfriend took a dna test that came back 79.99% and could not be excluded…… Could that be accurate or possible being the results were not 99.99 but below
IDENTIGENE says
In cases like this, it’s best to also test the mother’s DNA in order to strengthen results. In order to be definitively considered the father, results should be 99% probability or higher.
NICOLE says
I had a question. If i did a DNA test on two men and both came back 0 to 1, and I know those are the only two I have been with. What can be done if I paid for both of these test to be done and one has to be inaccurate because I witnessed both paternity test and I did my DNA in both?
IDENTIGENE says
Hi. It’s hard to say what’s going on. Especially when both tests came back negative. When a test is negative, we do a double-blind test to ensure the results are correct before releasing them. I suggest you give us a call at 888-404-4363 and an expert can go over your results with you.
selva kumar says
The alleged father, Mr.chandru, cannot be excluded as the biological father of the child, Baby of Miss.Ramya
Based on the analysis of the DNA loci listed above, the probability of paternity is 99.9991% when compared to
an untested, unrelated random individual of the population (assumes a prior probability of 0.5).
Could Explain me the above paragraph of the results, in simple language
IDENTIGENE says
Hi, Selva. It means that we consider the possible father who was tested as the biological father. The probability of paternity is 99.9991%, which is the highest level of probability possible.
selva kumar says
Hi IDENTIGENE,
Are you saying it is as Possible only, you are not telling as he is the Confirmed biological father? i don’t understand ,why you are not telling as 100 % sure ,he is the biological father of the child,the report showing as 99.9991%,why not 100 % it is not displaying.there is a difference between possible and Confirmed.Possible means he may be or may be not, i hope.am i correct ?
IDENTIGENE says
Hi, Selva. We can’t say 100% without also testing all other men in the world, basically. So that number is as certain as possible. The number of 99.9991% would be accepted by any court as absolute proof of paternity. The reason your results report says “not excluded as the father” instead of “is the father” is because we can’t give the 100% number. If you want further explanation of your results, feel free to contact us directly at 888-404-4363.
gary edwards says
Once i have completed the swap,and have placed them in the envelope.How long can the swaps sit in the envelopes before i send them off.
IDENTIGENE says
Hi, Gary. The samples are good for six months.
Zamzam Baku says
In a paternity test, if the alleged father’s DNA is submitted as the Child’s DNA ( as well) i.e. the laboratories would be testing the same copies of the DNA from the father, would the tests conclude that the DNA comes from the same individual? Or would the test conclude there is a perfect match? Can DNA from the same individual show differences?
IDENTIGENE says
Hi, Zamzam. There can be no perfect match between two individuals on a paternity test unless they are identical twins. The problem would definitely be detected at the lab level and they would ask for new samples.
Crystal says
I collected my son and my own swabs. My ex collected his own, but he had automotive Grease and such on his hands. I haven’t received the results back yet, but is there a chance that by him not washing his hands the test could come back inconclusive?
IDENTIGENE says
Hi, Crystal. Automotive grease wouldn’t alter DNA, but if it got on the tip of the swab it could contaminate the sample. The lab would catch this and ask for a new sample, so there’s no chance that it could affect the results you’re given. Hope this helps!
Janet says
My son took one of your DNA home test. He and the mother of the child in question all collected the samples and packaged them up at the same time and in front of each other. The results came back as 0.0 percent he is the father. I showed her the results and continues to say he is the father. Is there any way to get a 0.0 percent if he is the father. As a nurse I believe the test are correct based on the facts that they did the swabs all together and did everything as directed on your instructions.
IDENTIGENE says
Hi, Janet. Seeing as all participants swabbed in the same room and packaged them up at the same time, we can safely conclude that the samples all belong to who they say they do. When we get a 0.0% probability of paternity, we test again using a different technician, just to be absolutely sure. You can therefore trust that the report is correct for the samples we were given.
Michael says
31% ?? Father or not..how inconclusive:(
IDENTIGENE says
Hi, Michael. I’m assuming you didn’t test with us, since we don’t give out anything other than 99% or higher possibility or 0% probability for conclusive results. I suggest calling the company you tested with and ask for clarification.
Katrina says
Hello,
Is it possible to have false positive result if two alleged brothers are half siblings and only one was tested for paternity?
IDENTIGENE says
Hi, Katrina. With their being half siblings, a test shouldn’t give a false positive. That being said, we always want to know if two possible fathers are related and it’s best to test both of them, whenever possible.
Katrina says
Please help again! Would there be some mismatches if the man tested was the “half”-uncle instead of the father? I am thinking about this false positive result. I know it can happen with full brothers but what about with half brothers??
IDENTIGENE says
Hi, Katrina. You should always advise the lab prior to if there is another possible father who is related to the one being tested. That being said, a half-sibling relationship will most likely not provide a false positive result. You are more than welcome to contact us directly at 888-404-4363 (M-F, 9 AM to 5:30 PM Eastern Time) and discuss it with one of our experts. Thanks!
Josh says
Hello I had a CPI of 2030 which seems very low compared to everyone else. I was wondering if including the mother would have possibly changed the results? There was an observed mutation and 10 matching allele sizes and a 99.95% probability of paternity, does this mean he wont look like me?
IDENTIGENE says
Hi, Josh! As long as the CPI is over 100, results are considered conclusive. Including the mother wouldn’t change the results of positive paternity…it just might change the percentage of probability (in your case 99.96% instead of 99.95%). The markers we use for paternity testing are not those that determine physical appearance. Hope this helps!
Heather says
What does a score of 99.86% mean?
IDENTIGENE says
Hi, Heather! That number is the Probability of Relationship percentage or, more simply, the percentage of probability that the possible father being tested IS the father. So in this case, there’s a 99.86% probability that this participant is the biological father, which is considered conclusive. It can never be 100%, because to get that percentage we’d have to test his samples against every other man’s in the world.
Avery says
I Tested My Daughter And The Results Came Back 99.89 Non Excluded I Believe 14 Markers Outta 15 Matched , I Want Her Too be biologically Mine But I`m Having A Hard Time Excepting The Results Since It Wasn’t 99.99 .
The Mother Claims To Have Not Slept With Anybody Else , She Was Not Included In The Test ,
How Different Is 99.89 To 99.99 ?
Can I Rest Assured That I Am Her Biological Father With A Result Of Only 99.89 ?
What Are The Chances Of Another White Male Being The Father ?
This Is Really Stressing Me
Thanks
IDENTIGENE says
Hi, Avery. You can be confident with any result from an accredited DNA lab that shows 99% or higher. No worries!
Ryan says
If you repeat the test (and assuming there is no error during the collection and testing process), will the same Genetic Markers be tested and will the Probability of Relationship percentage be exactly the same every time (for example, 99.85%).
IDENTIGENE says
Hi, Ryan. Your answers are yes and yes!
Sarah Sorscher says
Your website claims 100% accuracy and states that your tests are validated. Can you direct me to a published article or other information describing what measures were used to validate the test and establish that it is in fact 100% accurate?
IDENTIGENE says
Thank you for your question. We would be pleased to share with you the results of our validation studies and will have one of our research scientists contact you directly.
Aimo says
what does 99.996 mean?
IDENTIGENE says
Hi, Aimo! I’m assuming you are talking about the probability of relationship number on your test report. That means that there is a 99.996% probability that the person tested is the biological father. That’s about as conclusive as you can get with a paternity test.
Monica says
How can a result be not excluded with an index percentage of 78.618 and to be the father the percentage has to be above 99.00
IDENTIGENE says
Hi, Monica. the 78,618 number you refer to is not a percentage. It means that his chances of being the father are 78,618 times more likely than any other man with the same ethnic background. The chances of his being the biological father is 99.99%. So we consider him to be the biological father. Hope this helps!
Hannah says
My test results say “not excluded as the father” however the percentage is only 99% not 99.9% and the CPI is less than 1000 at 886.
What exactly does this mean? In the glossary it outlines that it has to be above 99% and the CPI has to be greater than 1000 to be inclusive making the result 99.9%.
I need help interpreting these results to determine yes or no. Is this because the mother was not tested? and it is still not definite unless she is tested as well?
IDENTIGENE says
Hi, Hannah. The CPI needs to be 100 or higher, and not 1000 or higher. I think perhaps you misread the article in that spot? I’m not sure what glossary you’re referring to. We consider a result with a 99% or higher probability of paternity to be conclusive. If you tested with us, if the mother’s DNA was needed to strengthen the conclusiveness of the report, we would have asked for her sample. If you have any help interpreting your report (whether you tested with us or another company), please give us a call at 888-404-4363 (M-F, 9 AM to 5:30 PM Eastern Time).
KP says
Because my son and I live in New York State the samples had to be collected by a third party. We faced some difficulty obtaining the samples from the alleged father because he lives in South America. After having a friend in the father’s country locate a lawyer willing to do the collection, we proceeded with having the alleged father’s sample collected. We ran into a slight problem because the materials sent to the collector were in English and the alleged father and the collector only know Spanish. Being bilingual, I was able to send copies of the forms with my annotations in Spanish of how the forms should be filled out.
What would be really great would be that Identigene translate the forms in Spanish and other pertinent languages so that in the future other people with similar situations might not have such a difficult time getting the forms completed in a foreign country. Also, having the Test Results available in printed Spanish would be very helpful.
Luckily the test results were worth the wait! Thank you, Identigene.
IDENTIGENE says
Hi, KP. Thanks for taking the time to comment. We do have both collector reports in Spanish as well as Spanish-language test results. I’m not sure why these weren’t used in your case, and I apologize.
Renea says
I understand that witnessing the swabbing is important to getting accurate test results; but what are the chances of results coming back negative because of unintentional mistakes? And also, what are some things we should caution to avoid mistakes?
Admin says
Hi, Renea. What a great question! Unintentional mistakes rarely affect results themselves. Most customer mistakes are caught at the lab level and the lab will simply ask for a recollection of DNA samples. It’s more a nuisance to the customer than anything else, because the need for a recollection means they have to wait longer to get results. So it’s optimal to simply follow all directions carefully the first time. One mistake that can affect results is if the customer doesn’t inform the lab ahead of time that another possible father is a relative of the possible father being tested (his brother, uncle, father, etc.). It is essential that customers be honest with the lab in these situations. For more information about common mistakes customers make, check out this blog: http://dnatesting.com/how-do-dna-samples-for-paternity-testing-become-contaminated/
Sylvia says
With the DNA test is it possible to determine the gender of the person submitting the sample?
Admin says
Yes. Each test includes a gender marker.
Meesha says
How many genetic markers do you test? I had a test done at a facility and they said they will only test 15 because that is all that is needed. Is that correct?
Admin says
Hi, Meesha. We test as many markers as are needed to get conclusive results. In most cases it’s 16, but we definitely do more, if needed.
Meesha says
Why would you not test the full 23 everytime?
Admin says
The vast majority of cases for paternity don’t need it, so testing 23 markers routinely drives up costs for no reason. We can keep prices low by testing only what’s needed for conclusive results, but we absolutely test more markers if/when the genetic analysis requires the data.
shelly says
I know my second child’s father is different from my first, but the test came back 99.9 full siblings. But also said assumes prior probability equals 0.50. Does this mean they are half or they do have the same father? My second child looks identical to the other man, and his other children!
Admin says
Hi, Shelly. We think perhaps you’re not reading the report correctly. Did you test with IDENTIGENE? The email address listed for you here doesn’t match any cases in our files. It’s probably best if you call us directly at 888-404-4363 and we can more accurately answer your question than I could here with limited information. Thanks!
Bebe says
My boyfriends mom did a at home test on my baby while I was in hospital and when they cam back it was 0% change he is the father but the numbers are off by one or two and he was the only one I had been with I don’t understand the number please help me understand
Admin says
Hi, Bebe. Are you saying there are mismatches at one or two places? I’m trying to understand what you mean by “the numbers are off.” If there are mismatches at one or more markers, then yes, there should be a 0% probability of paternity.
Tim says
I had a paternity test taken before my baby was born the results was 98.7 does that mean I am not the father?
Admin says
Hi, Tim. You’ll have to ask the DNA lab you tested with and see what they say. But it looks as if you are the biological father.
Tim says
SO the 99.99% doesn’t apply in this case?
Admin says
Most courts accept 98% or higher, but I’m not sure why the company you used wasn’t able to give you a 99.99% number. I’m sure they could explain if you asked them.
Tim says
Ok , just making sure because their was another man involved
Tim says
I did ask them if was told anything in the 90’s would determine if was the father
Admin says
So unless the other possible father is a close relative of yours, you can most likely be confident in the results.
Sarah madrid says
Hi, I’m not sure if this is something you can answer or not. I did a home test through identigene for my son. My results came back as 99.99%, so thanks for helping me figure out his father. I was just wondering about the individual markers, my sons father has some areas with only one number and my son has 2 numbers, could this mean a possible birth defect?
Admin says
Hi, Sarah! No worries. All it means is that your son had two of the same gene at that particular marker. For example, most markers show two different numbers: 12,4. But when the marker is 12,12 only a single number is shown on the report: 12. This means your son got two of the same gene (one from each parent) at that particular location in his genetic profile.
Hope this helps!
Issac Fernandez says
What does CPI 64,450,093 means ? Probability paternity 99.999998% ?
Admin says
Hi, Issac. It means that the alleged father who was tested is 64,450,093 times more likely to be the father of the child tested than any other random, unrelated man with the same ethnic background. There is a 99.99% + chance that the man tested is the biological father of the child. We definitely consider this man to be the biological father of the child!
shonda says
Hi, I recently did a home Dna test between my child and boyfriend. The test came back 0%. The company I used only tests 16 markers. Is there still a possibility that he is the father? Also I read that certain things could “mask” Dna such as smoking drinking or eating prior to doing the test. How true is this?
Admin says
Hi, Shonda! Testing 16 markers is the standard. Most DNA labs only test additional ones if they think it can lead to more conclusive results (a higher probability of paternity). Smoking, eating, etc. doesn’t mask DNA as much as it can degrade it. If this is the case, the problem is caught at the lab level when testing begins, and the lab would ask for new samples. Testing would proceed with the new samples and then a report is issued. So, it shouldn’t affect results. Did you watch your child and boyfriend swab their own cheeks and put the samples in the envelopes? Did you all mail samples together? If you said no to any of these, there’s a possibility your boyfriend could have submitted someone else’s DNA as his own. Something to consider . . .
James says
I took a DNA test with my father who informed me recently that my Uncle might actually be my real dad and the results came back 0% possibility (and I saw him do the sample). Does this also exclude my Uncle before I pay another 89$? Please Help.
Admin says
Hi, James! No, it definitely does not exclude your uncle.
SAMUEL MPIANA says
Can you please explain this result to me in a simple way. I had done a DNA test and the result came this way. Does it mean that I am the father?? as we shared the majority of the markers, only 2 which are not identical.
Based on the DNA analysis, the alleged Father, (………), cannot be
conclusively excluded as the biological Father of the Child,( ……) because they share a majority of genetic markers. Of the genetic identity systems tested 13 of 15 match – the two exclusions may be due to mutation. The probability of the stated relationship is 0%
The possibility exists that a direct relative of the alleged Father (s Parent, Child or Sibling) could not be excluded as the biological Father. The probability of such an event is 97.983870967742%
Admin says
Hi, Samuel. If I’m reading this correctly, they are telling you that you are not the biological father of the child, but that there is a 97.98% probability that a close relative of the man tested IS the biological father. It could be your father, sibling, etc. I highly recommend you contact the lab with whom you tested directly for confirmation.
DYANNA says
WE DONE A TEST ON A CHILD THAT IS SUPPOSED TO BELONG TO MY HUSBAND AND THE RESULTS CAME BACK HE HAD A BETTER CHANCE THAN A UNTESTED MALE AND THE RESULTS WHERE 99.7%. DOES THAT MEAN THERE IS A CHANCE THE CHILD ISNT HIS? I WAS TOLD IT WAS SUPPOSED TO BE 99.9 AND ANYTHING UNDER WAS HE COULDN’T BE
Admin says
Hi, Dyanna. What you were told is not true. If these results were being used in court, your husband would be considered the biological father for sure. Anything above 99% is widely considered conclusive, although the goal is always 99.99%. Most likely if your DNA samples were included in testing, they would have strengthened the results even more. No worries! He’s the dad.
Ceecee says
I did a sibling DNA test on my son and his sister to prove they have the same dad, I also included swabs from myself but none from the mother of the little girl. It came back as 99.5% probability of half siblingship which means they are brother and sister correct? I don’t understand why it says the likelihood they share a same parent is 236 to 1, what does that mean, and why is it such a low number?
Admin says
Hi, Ceecee. Yes, with such a high probability of relationship, they would be considered brother and sister. The relationship index number just means that the 99.5% probability is 236 times more likely if the children share a parent than if an untested, unrelated person of the same race is the parent. That 236 to 1 ratio is determined based on statistical formulas that take into account both the genetic data and the race of the participants. The markers of the participants may be more common to the population at large within that race group, which is why the number is “low.” Whether the ratio is 1,000,000 to 1 or 236 to 1, it doesn’t change the most important fact, which is that the lab determined they are siblings. It’s really hard to explain this simply, but I hope this helps!
Stephanie says
Hey my name is Stephanie and my daughter is four months and me and her father took a home DNA test but i believe he cheated on the home DNA test cause the results came back zero percent paternity but when everyone see my daughter they say she look just like him and go take another DNA test what should I do
Admin says
Hi, Stephanie! First of all, please keep in mind that looks alone are not an absolute determinant of paternity and should never be considered proof. Unless everyone participating tests in the same room in each other’s presence, seals up the envelopes in each other’s presence, and drops the samples in the mailbox at the post office in each other’s presence, there is a possibility of fraud. If you suspect this happen, by all means retest. But this time complete each step in the process in each other’s presence. The other possibility is to arrange for an impartial witness in your area to check IDs, witness sample-collection, and take care of mailing. Results from a witnessed test are also court-admissible. If you want to go this route, call us at 888-404-4363 and we’ll make all the arrangements for you. Hope this helps!
William Ferris says
My dad is 73 and never new who his father was. A letter was found from my dads uncle (his mothers brother) with a picture of someone that looks just like my dad. I found his son who is 61 and lives across the country. Will a paternity test determine if they are truly brothers?
Admin says
Hi, William. With testing just the two men there is a high chance of getting inconclusive results, unfortunately. Ideally, we would also test both their mothers, which would greatly increase the chances of getting conclusive results. If this isn’t possible (and the men’s ages would suggest perhaps their mothers are deceased), then having other very close relations participate could also help. It is a little complicated to explain the possibilities in a response to a blog comment like this. I highly recommend you contact us directly and speak with one of our relationship experts: 888-404-4363. They will be able to assess the options based on information you give them and more accurately make a determination of whether your question can be answered. Thanks!
Brittany says
Hello I did a silibingship test and my results came back and said 96.3 and 26 to 1 what does this mean?
Admin says
Hi, Brittany. The results you mention suggest that there is a 96.3% probability that the relationship you tested for is positive and the chances of this relationship being positive versus if the test were conducted with a different unrelated participant is 26 to 1. But without having your test results in front of me, it’s impossible for me to say this with any certainty. Have you tried calling the lab where you tested? They are your best resource.
Brittany says
No I just tested my two sons to see if they share same father and my results said combined silbingship index 26 and probability of half siblings is 96.3% amelogenim for the both of them x and y soI googled to see what it meant and saw I can leave comments and decided to see if maybe you all could help me with the results
Admin says
Gotcha. Our opinion is that is a very positive probability of relationship, especially for a siblingship test, and your two sons share the same father.
Amy says
Hello, my question is this, I was told that a man who is deceased today was my real father, so I got together with that mans daughters, daughter. If he is my father, she would be my half sisters daughter……So, She and I did a swab test and the results were probability 0.2% I read your stuff and it says the aunt or uncle has to be a sibling of the father? I am not a sibling of the father I am the daughter of the father…so what do the results mean? Since there is not a 0.0 % probability are we indeed related? Thanks so much for answering!
Admin says
Hi, Amy! The relationship between you and the woman you tested with is such a distant one, genetically speaking, that I’m not surprised you got such a low probability of a biological relationship from the lab you used. When the alleged father isn’t available to test, it’s critical to involve as many of his closest relatives as possible, PLUS your own mother. It’s like putting together a jigsaw puzzle to determine a relationship…the more pieces, the better. If you tested with the man’s daughter (not his granddaughter, like you did) plus your own mother, your chances of getting conclusive results are much, much higher. If you want more options, please feel free to call us and speak with one of our relationship-testing experts: 888-404-4363.
Tay says
Hi , so I was wondering how I receive my test results. I went to make an online account but I was paying with money gram so it didn’t let me make an account. How will I be notified when my results are ready?
I’ve read you get an email & you can log in once your results are ready with ur email & password included on the paper you fill out and sent, would the password be my 6 digit code you guys had me create ?
Admin says
Yes on all counts, Tay. If you have any other questions, feel free to give us a call directly at 888-404-4363.
Martha says
Can you comment on the residual paternity index in cases of exclusions? I read somewhere that high residual PI may indicate that the true father is a relative of the alleged father.
Admin says
Hi, Martha! Yes, that’s definitely true. If the analysts suspect that the biological father may be related to the man who was actually tested, they indicate it on the results report.
kevin says
Friend took a blood test on a child mother was married test came back 98.9 I to was with this women and the child looks just like my two boys .he just took a swab test . but the Cort ordered child support on a 98.9 .
Admin says
Hi, Kevin. DNA is the same whether you collect it via a blood sample or a cheek swab. Without knowing the details of what happened in your case, it’s hard for me to comment on specifics, unfortunately. A 98% probability of paternity was a high enough percentage for this court to confirm results, apparently. But keep in mind that looks alone are never proof of paternity. Good luck!
Collin says
The mother, daughter and alleged father have very similar features with 6/15 of the same genetic markers. Is it possible that the mother and father could be half siblings (same father).
Admin says
The genetic markers that are compared for paternity testing do not code for physical appearance, and looks are never an absolute determinant for paternity. I’m not sure what you mean by “identical markers.” Do you mean that both alleles at each marker are the same for all three participants at 6 or 7 locations? For example, do all three participants show 13,15 at one locus? If so, that could be completely coincidental. What is essential for paternity is that the child, at EACH locus, have one number that matches the alleged father at the same locus and one that matches the mother (for example, if the child is 13,15: the 13 should match one of the mother’s numbers at the same locus and the 15 should match one of the father’s numbers at the same locus, or vice versa). From what you said it sounds as if only half have a match and that means a 0% probability of paternity. Now as to the real father being biologically related to the man being tested: If you used an accredited lab and analysts suspect that the biological father is related to the man tested, it is usually noted on the report.
Collin says
Example:
Mother=11,14
Daughter=11,14
Alleged father=11,14
All participants have the same alleles for 6-7 different markers.
Admin says
I double-checked with our lab director and she says that although that’s a little bit of a high number of matching markers for all participants, it could very well happen. She suggests that, if it helps your own peace of mind, that you have your own individual DNA profile done and compare that profile with the one used for this test. This would ensure that your profile was indeed used in this test and not a different male relative’s related to the mother.
Admin says
Another possibility is that participants could have mislabeled the sample envelopes: labeled the mother’s as the daughter’s and the daughter’s as the mother’s. Just something else to consider.
Marie says
The scenario: Man X allegedly has sex with his wife’s sister, Y, who, in any case, became pregnant by someone. This is kept secret. Years later, the daughter of X and the son of Y, who’d been raised as cousins, want to know if they’re related as half-siblings. Testing comes back with a 70% probability that share the same father.
What does this result mean? It’s unlike the testing of a man and his alleged offspring, so I’m confused. I know that 70% probability result in a test of a man’s DNA and the DNA of his alleged child means he’s “not excluded” but likely is not the father, but what about a scenario like the one I described?
Admin says
Hi, Marie. Was the DNA of either mother involved in the testing? I’m guessing their samples were not submitted. If they had been, there would probably have been more conclusive results. It’s also essential for this type of testing that the participants let the lab know ahead of time that the two mothers are related, because it affects the analysis. It’s not surprising, then, that ambiguous and non-conclusive results were given. Unless a certain threshold for percentage of relationship probability is met (say, 90% or higher), a lab cannot give “for sure” results. It would be advisable to consult with experts at the lab where you tested. At the very least they may recommend that the mothers add their DNA to the test and then re-do the analysis with the knowledge that the two women are full sisters. Good luck!
DJ says
I just took a DNA test of my 4 children with my ex wife, but only one of my results states 99.98% that I am the sibling or parent of this child. The other 3 test’s states that I’m not excluded but their test don’t state I’m the father nor does it have the 1.0 to 1.1 chance. Theirs say 99.99999993 and it have this large number of how many people it could be but I’m not excluded. So does this means I am also their father even though its not stated on their test? I’m confuse can you please let me know.
Admin says
Hi, DJ. I’d have to actually see your report to comment on the specifics of how it’s worded. But with probabilities of paternity such as you describe for all four children, it certainly sounds as if it can be confidently assumed you are the father of all four children. I highly recommend, for your own peace of mind, that you contact the lab you tested with and have them confirm for you.
Emily says
A woman is claiming to be my husband’s daughter. Her and his biological daughter (along with their mothers) took a sibling DNA test (mailed in to some company…don’t know name of it). The results: Combined Siblingship index: 20,853. …the probability of half siblingship is 99.995%. The likelihood they share the same biological father is 20,853 to 1. … They are both claiming the results say they are half-sisters based on 99.995% and I understand that but I don’t understand the following statement: The likelihood they share the same biological father is 20,853 to 1. … The timeline of my husband being with this woman and the birth of this child doesn’t add up and my husband swears she’s not his. The DNA test results do not say what company this is. How can he be the father out of 20+thousand men? Please help explain, we’d like answers.
Admin says
Hi, Emily. You can trust the results. The CRI of 20,853 to 1 just means that your husband is 20,853 times more likely to be the father than an untested, unrelated man of the same race.
Isaac says
I was wondering is there a way someone could be father after looking at the first 15 alleles. It was at 0%. When I look at the numbers, it looks like they mat got the information incorrectly.
Admin says
Hi, Isaac. A profile of 15 alleles plus the sex chromosome is standard for paternity testing. An accredited lab will test additional markers when necessary, but that’s relatively unusual.
Isaac says
The reason I ask she insists I am the father. She was not with anyone else. I don’t believe her anymore. Can I send the results?
Admin says
Yes. You are always welcome to have us look over your results. Just contact us via email and send the report as an attachment: info@identigene.com.
Crystal says
Hey My name Crystal I had a DNA test done it came out 5 % …what do that mean
Admin says
Hi, Crystal. Was it a paternity test? When you test with an accredited lab, the results are usually 99% or higher probability of paternity or 0%. So not sure where you’re getting that 5% number?
Brandy Fuller says
My husband took a test with a lady that his mother said was his aunt.. the results are as follows… what does this mean?
The DNA from the alleged relative was compared to the tested child. Based on testing results obtained from the analyses of the DNA loci listed, the probability of relatedness is 0.3%. The likelihood that the alleged relative is not the biological relative of the tested child is 319 to 1. This probability of relatedness was calculated by comparing to untested, unrelated, random individuals of the Caucasian population (assumes prior probability equals 0.50).
Admin says
Hi, Brandy. Just based on the information you’ve given me, it appears that your husband and his possible aunt are not biologically related. A .3% probability of relationship is extremely low.
Bee says
DNA can change once a person develops a mental illness. IF the child was conceived before the mental illness was developed and a test was done on the alleged father and the child which came back as not his, can his current mental illness play a factor in this if the lab that conducted the test had no knowledge of his mental illness.
Admin says
Hi, Bee. The answer is no. Mental illness does not affect the genetic markers used to determine paternity.

Allen says
Hi, I’ve read many of your responses which state any more than 3 mismatched markers would be considered an exclusion.
However, If 2 DNA tests were performed by 2 different companies with the same identical results and both tests showed 8 out of 15 mismatched markers resulting in a 0% probability of paternity and a PI of 0, is there ANY possibility that the results could be a false exclusion if the mother says both her and the child have chromosome mutations and duplications? Thank you!
Identigene says
Hi, Allen. Analysts take the possibility of mutations into account when doing their work and test more markers if they deem it necessary to get conclusive results, so you can trust the exclusion reports.
Vero says
Hi, I have a paternity test done before my baby’s born, but when I called they said the result is 50%, so they had to run again, because it can either be 0% or 99%, but when I asked what does 50% mean, they can’t answer. So I’m wondering does it mean it can possible be the father? Cuz if not, it will just show 0%?
Identigene says
Hi, Vero. Probability of paternity is based on statistics. The percentage is based on the chance of the man tested being the father versus a random man of the same ethnic background. 50% is definitely not conclusive, so testing more genetic markers becomes necessary.
Liz says
Hi, I have a question regarding the conclusion of my DNA test. Why does the CPI indicates 0 to 1 rather than just 0, and what does the “Prior Probability of 0.5” mean. Your assistance would be greatly appreciated.
Conclusion:
Combined Paternity Index: 0 to 1
Probability of Paternity: 0.0000% (Prior Probability = 0.5)
Identigene says
Hi, Liz. Here’s the answer from one of our geneticists:
A paternity exclusion states a CPI of 0 and a Probability of Paternity of 0%.
For inclusions, a prior probability of paternity is used to generate the Probability of Paternity. The prior probability is the non-genetic odds in favor of paternity (ranging from 0 to 1) and is sometimes adjusted by the Court. We use a 0.5 for the prior probability (considered a neutral position) which is commonly used by paternity laboratories. When the prior is 0.5 the Probability of Paternity is CPI / 1 + CPI.
Anonymous says
Can you compare DNA profiles on 2 separate tests to determine likelihood of paternity? I’m just trying to determine whether getting a new DNA test is worth it. The situation is such that the father of my child may have a child by another woman. He has came out and told me that the test he took with her child, his friend actually took the swab -there was no witnessing.
Identigene says
We would require new DNA samples. And to be sure there’s no fraud going on like there was in the one test, I highly recommend that it be a witnessed, legal test where are participants’ IDs are checked and DNA collection and submission are supervised. You can learn more about it here: http://dnatesting.com/how-the-paternity-test-kit-works/paternity-test-for-child-support/ or call us at 888-404-4363.
Michelle says
I have a question… I have not yet taken the test. However, I am hoping to get the test to send in. I was told who my dad is/was. He passed away before I could find him. I have contacted his children and we agree we want to know if we are indeed siblings. Because we are all in our 40’s-60’s, will the DNA test be able to tell us if we are indeed siblings. My mother is still living as well as my potential siblings mothers are. Would we need to include a swab from my mother as well as theirs to determine the likelihood of paternity? I am unsure if any of his siblings are still living or not as he passed away in 2005 at the age of 83.
Identigene says
Hi, Michelle. All mothers should definitely test as well, if they are all able and willing. I highly recommend that you contact us directly at 888-404-4363 to speak with one of our relationship-testing experts. They’ll be able to tell you in detail what your best options are and what the pricing would be.
Taffy says
Hie..had a DNA test done for my son and his fatherbut itcame back written excluded from being the biological father yet have never slept with anyone besides him what does that mean….
Identigene says
Hi, Taffy. It means that, according to the samples that were submitted for testing, this man is not considered to be the biological father of the child.
Arlita says
How many times are the samples tested? Paternity test done on my husband and a child that He’s believed was his for almost 5 years. The results came back 0%. I collected the samples myself as soon as they woke up in the morning that day. I’m just wondering how legit the answer is.
Identigene says
Hi, Arlita. We know results can be life-changing, so we run all tests twice. Since you did the samples yourself, you know that the DNA belongs to the right people and can trust the results absolutely.
Arlita says
Thank you so much! I appreciate you guys answering my question.
Identigene says
You’re very welcome! :-)
Jennifer Rodriguez says
I went through a different lab, and did 2 Paternity tests for myself and 2 other gentleman. Each test came back: Probability of Paternity: 0% and Combined Paternity Index: 0%…so in both cases, neither man is my biological father. My question is…On the first test (first man), the DNA Locus has a “Penta E” with comparable numbers to myself…the second test (second man) does not have a “Penta E” listed in the DNA Locus. I understand these men have been excluded…but, what exactly is the “Penta E”? And why does one test have it, but the other does not?
Identigene says
Hi, Jennifer. Penta E is the name of a locus (location in the DNA) used for relationship testing. Penta E was no doubt included in the commercial kit used to perform the paternity testing for one of the cases. It is possible that a different commercial kit manufactured by a different company was used for the second test and that kit did not include the Penta E locus (Penta E is the intellectual property of the first company). At any rate, the difference in nomenclature doesn’t affect test results one way or the other.
Steve gopal says
A mom two children and a dad has taken a 20 Marker DNA test. Why don’t the children marker results and PI don’t match? Is this an error The results for both children are 99.99% .
Identigene says
Hi, Steve. Without actually being able to look at your test results to see what exactly you’re talking about, it’s hard for me to answer your question. That being said, if the results for both children are 99.99% probability of paternity, that’s the most important part!
Steve gopal says

I just have a quick question can I send you The Dna result I think it is inaccurate because they are some mismatches in some markers. Please it would help me a lot thank you
Identigene says
I suggest you contact the lab you tested with and they can go over your test results with you.
Irene Lopez says
I had a test done to prove grandparents paternity as my son is not here to do so and the mother says her daughter is my sons,and it came back as prior probability 0.5%.it also says the probability I am her grandma is 25.5181%. I just want to know what this all means, I asked the DNA company they just said it is hard to tell. I just want to know if she is my granddaughter. I have spent so much time with her. Thank you
Identigene says
Hi, Irene. The test results you were given were inconclusive. Did the child’s mother test too? That could really help to strengthen results.
Irene Lopez says
No she did not test, I am going to see if she will. When tried to test her but the company who did her testing said it would not make a difference with her DNA it had to be from my son or even my sons father (grandfather) . Thank you
Becky says
I had a test done on my daughter and alleged father they have 10 marker matches and 5 that did not..it says probability 0..is this 100% accurate that he can in no possible way be the father
Identigene says
Hi, Becky. I answered you earlier. Did you not see it? Here’s what I said: H Since a child gets 50% of their DNA from each parent, there has to be a match at every marker in order for the man tested to be considered the biological father. With five mismatches, the man tested is not the father. The fact that there are some matches at other locations is not that unusual. I don’t know if you tested too or not, but you may also have the same gene at that location and she may have gotten it from you.
Ks says
Hello I did an at home DNA test with my child’s father and with myself and my child. The probability of paternity came back 99.99999% that he is her father. They tested 20 loci and came back with a CPI of 35,648,161. However there were two mismatches at the FGA (my numbers were 21,23 my daughters were 21,25 and her fathers were 24,26) and the other was at CSF1PO (my numbers were 10,11 my daughters were 10,12 and her fathers were 10,13). They stated that either scenario could be that she was not his child but a possible relative (which is impossible we don’t speak too or live by any of his family) or that she was his child but she had a double mutation in her genes. If we were given the probability still of paternity at 99.99999% is there any chance that he could not be her father??
Thank you in advance for your help!
Identigene says
Hello to you! If the lab is highly-accredited, then you can trust results. The likelihood of mutations is calculated into the probability of paternity in cases like these.
Angel Ennis says
I had a DNA test done about 5-8 years ago and lost the results it was on my son and who I believe is his father I didn’t include myself. I was wondering how could I get another copy and what the results mean cuz I was confused
Identigene says
Hi, Angel. When Identigene was purchased by our new owner (DDC) in December of last year, files for past reports were passed on, but only going back one year if it was a home test and up to 5 years if it was a legal test, so we won’t be able to provide you with a copy of your report. I’m so sorry about that!
Angel Ennis says
Ok I remember that the test had said .50% and half the genes matched between the both of them is this because I didn’t test myself?
Identigene says
Is it possible you’re not remembering the percentage correctly? Because we don’t issue paternity results with a low percentage of probability like that. It’s always 99% or higher, or 0%. If only half the genes matched between the possible father and child, then adding your DNA would not have made a difference toward strengthening results. And if it could have possibly made a difference, the lab would have asked you for your sample before issuing results.
Rich Coleman says
I had an DNA test done the mother did not get swab. the results said probability of paternity 95% does that means I’m the father
Identigene says
Hi, Rich. A 95% probability of paternity is not considered conclusive. I would contact the lab where you tested and see what can be done.
Rich Coleman says
Thanks because I’m confused . Because the results said non-excluded 95%.
My mom said that the 95% was to low. I figured it was because the mother didn’t get tested.
Identigene says
It could be, but it’s hard to say without seeing your report. You should really contact the lab where you tested for clarification.
John says
I have had 4 paternity DNA tests conducted. 3 for children from marriage, whose results were all 99.999999999% POP, and 1 from before the marriage who’s results were 99.992% POP. How can the two ends of the test result spectrum BOTH equal paternity? And doesn’t that imply that everyone who is tested and receives a POP of anywhere between 99.99 and 99.999999999 will be identified as the father? Why isn’t a match (99.999999999%) the standard? It’s easily achievable., in fact – isn’t that the result every known father-child test will result in, just like my children? And, doesn’t 99.99% indicates that this result is 10 Million times less likely to be the father, than the 99.999999999 result? I get that both are in the “pool” of potential fathers. One is very obviously the father, the other, not so much. Please explain?
Identigene says
Hi, John. A paternity test isn’t like a lab test, where you get a straight yes and no answer: Yes, you have diabetes or no, you don’t have diabetes. Probability of Paternity, as its name implies, is calculated based on statistics. Many factors go into the formula for arriving at the number, including the probability of having certain alleles at certain markers based on ethnic background. This is why there is variation in POP from person to person. Not everyone is going to get a 99.9999999% of probability. In fact, in some cases, the percentage calculated for paternity is in the low 90s,for example, and in those cases the mother’s DNA is needed to strengthen results. I’m not sure where you get the “10 million” number. Each paternity report includes a Combined Relationship Index (or Combined Paternity Index) number. This number shows the odds that an unrelated, untested man with the same ethnic background could be the biological father. Some examples might be 3,913,000 to 1 or 22,000 to 1, etc. A man who gets a 99.992% POP with his child is the father every bit as much as a man who gets 99.9999999% with a different child.
Kevin Parkison says
Is it possible for a Paternity test to be inconclusive? In other words, is it possible that the test can not be used to prove the parents?
Kevin says
To expand, I mean even if the parents are the ones in question.
Identigene says
Hi, Kevin. With today’s advanced technology, it’s extremely unlikely that an inconclusive result would ever be obtained if testing the possible father with the child in question. A standard 16 genetic markers are compared between father and child. If results are not conclusive, then either the mother’s DNA is requested or the lab tests additional markers until conclusive results can be obtained. Now, if there is another alleged father who is a close biological relative of the man being tested, the lab should be notified so that they can take that into account when doing their analysis.
John says
Thank you. I fully understand how DNA is tested and what the factors are and the use of mathematical predictive models. And I am fully aware that the mother needs to be included to get the numbers we are discussing. I’ve had non-mother included tests done as well. However, none of that addresses my question…which was “How can the two ends of the test result spectrum BOTH equal paternity?” Your response seems to indicate that If I take multiple successive paternity tests with my children and wife, then I could receive any number on the scale of 9’S between 99.99 and 99.999999999? I’m asking for clarity as to WHY and HOW, not what. I get all the what. I’m asking why and how the results of the exact same paternity test, given to the exact same like-kind known father-daughter-mother combinations can result in such extremes? NOT THAT it does, but why does it? I say because there are, as the CPI indicates a significant number of men who share the exact same DNA match at all the 9’s below 99.999999999, from 1 in millions – to 1 in thousands, and if that is true, then how can that person be declared the father – he’s no more that the first person to be tested of the thousands who have that exact same match. Thanks again.
Identigene says
I apologize if I’m not answering your questions in the way you want, John. It’s hard to have this kind of conversation in writing. Just to clarify, are you talking about getting different probabilities if you test with the same child twice?
John says
Yes, but I’m asking in context of HOW can I be the father at 99.99% POP with mother included, and also be the father at 99.999999999% POP with mother included. I fully understand the 99.999999999% POP with CPI to match 100,000,000. That is obviously a very high fidelity match, as with my known children, all receiving that match. So, if MY children receive 99.999999999% POP, then how can a child with a 99.99% POP also be my child? Why did that 4th child receive such a relatively low POP, unless she is not my child? What changed in the testing routine between the children to make 99.99% POP fatherhood and 99.999999999% POP also fatherhood? We took the exact same Paternity DNA test for all 4 children. CPI, I thought was also an indicator of the number of mathematical males in the gene pool who could potentially be the father at a specific POP? For instance 99.99% POP and 10,000 CPI would indicate that 1 out of every 10,000 men in the gene pool that I come from will have that exact same level of fidelity match (99.99%) with the child. Because I am a white Anglo Saxon male with lineage from Ireland, England, and Northern France – THE gene pool that established and populated America, and is still nearly 40% of all males in America – that’s around 40,000 men who will receive 99.99% POP and 10,000 CPI with this 4th child. What am I missing? What am I misinterpreting?
Identigene says
Remember that statistics drive the paternity index number at each locus, so if you match one child with a marker that has a high probability at that location for the general population, then it will be assigned a lower PI number for that location. If you match another child at that location with a gene that has a lower probability at that location for the general population with your ethnic background, then it will be assigned a high PI. That ultimately is what makes the difference between at 99.9999999% CPI and a 99.99% CPI. You need to keep in mind the bigger picture: you are the father of all these children, no matter the CPI for each. I hope this helps!
Trisha says
How many of the Alleles need to match in order for it to be listed as not excluded, and are we looking at the Y alleles only for a father/son match? And what if the envelopes were not correctly marked in which one was the fathers’ DNA as opposed to the childs’ DNA, does that make a difference?
Identigene says
Hi, Trisha. All alleles must match in order to get a conclusion of a biological father/son relationship. If the names on the sample envelopes were switched in a situation such as you describe, it doesn’t make a difference in the outcome, no.
BC says
I’m a grandmother who got a dna test on the alleged granddaughter. It came back genetic evidence does not support the biological relationship. the probability of relatedness is 4.1%. What does 4.1% mean?
Identigene says
Hi, BC. It means there’s a 4.1% probability that you’re biologically related, which is extremely low. You are not the child’s grandmother.
preet says
I wanted to know that dna test provide the information about the sexual relations with any third person or not
Identigene says
Hi, Preet. No, it does not.
preet says
Thank you i was confused in madical test and dna test
Crystal says
I did an DNA test on my fiancee and his assume son and I did the test and seal the envelope .. One problem I licked it now I put the sticks at the button
will that make a difference on this test …
I have to know
My fiancee is American African and his son is suppose to be American African and Caucasian
I am also American African
Identigene says
Hi, Crystal. It shouldn’t matter, no. A paternity test does not determine ethnicity, so that’s not a factor here. If the lab sees that there are two profiles on the swabs (or a female sample when the swab should be for a male), then testing is suspended right away and new samples are requested before results are issued. So, no worries!
Joshua says
I submitted a paternity test for my wife, daughter and myself. In the last locus index is the amelogenine. In my daughter’s it shows X Y…. Doesn’t that mean the DNA submitted is male? I believe I could have been duped by my wife and she used my son’s instead of my daughter’s.
Identigene says
Hi, Joshua. If it shows xy, then yes, it was a male sample.
Gavin says
Hi
I recently had a test with DDC and although the result is 99. 999999%, I have one question….
What is the difference in a mutation and an mismatch in allele?
I understand it’s nothing to worry about and I’m not…
I’m just curious and cannot find an easy to understand answer!!
Thanks in advance
Identigene says
Hi, Gavin. Great question! A mutation is a permanent change for a particular gene at a particular location that is different from the gene you would expect to see for a person of a designated ethnic background or in the general population. For a paternity test, there must be a match between possible father and child at all locations tested. Well, if the man tested or child has a mutation in one location, that could cause a mismatch (genes that don’t match) even if they are biologically related. All possible mutations are taken into account when doing the analysis, and so if there is a mismatch at a location, it doesn’t necessarily discount the man from being the father. The analyst may do more testing to confirm results one way or the other, if needed, when a mutation is present.
Gavin says
Thank you for your answer…. So, although it is a slight mismatch, it’s obviously nothing major with a result of 99.9999%!!!
Thank you for your response :)
Identigene says
No worries!
Tajanie says
Is there a way I can get a copy of my result with our names?? I need it to add him to my insurance.
Identigene says
Hi, Tajanie. Your results didn’t have names because it’s an at-home test and the participants’ identities cannot be verified. If you need results for insurance or legal reasons (inheritance, social security benefits, etc.), you need to do the test again and it needs to be a legal test where DNA collection and submission to the lab is supervised by an approved witness. You can learn more about it here: https://dnatesting.com/establishing-paternity-and-legal-paternity-testing/
Danielle says
My results read 99.9999999997….. does that means he is the father
Danielle says
We are also in the process of going to get swab by another lab through the courts,will it still say the same thing,
Identigene says
If the same DNA is submitted for your court-ordered test, it should say exactly the same thing, yes.
Identigene says
Yes, it does.
Carrie says
I did a grandparent/child relationship test. Results were 78.3% probability and 3.6 CRI….I know its not conclusive. It was a grandmother and male child and mothers dna…What does that mean?
Identigene says
Hi, Carrie. It means just what you said: that the DNA you all share could not yield conclusive results one way or the other.
Lisa says
I am having trouble making my son believe even after your test came back 99.998% that he is the father all due to this statement in the report…The probability that someone else is the father is also 50% (or 0.5). so he believes that there is a 50% chance that someone else could be the father too how do i explain this to him to make him believe because i do not understand this statement either
Identigene says
Hi, Lisa. Can you copy and paste the statement you mention? A 99.998% probability of paternity is very conclusive.
Hollywood says
Did I contaminate my swabs by placing them back into the original seals before placing them into the collection envelope?
Identigene says
Hi. The reason you shouldn’t put swabs back in the plastic packaging is because, if they’re not sent in to the lab immediately, the swabs could develop mold growth. If you sent them right away, they’re probably OK. If the lab determines swabs are contaminated in any way, testing is immediately suspended and the customer is asked for new samples, so results are not affected.
chasity says
We are having trouble understanding the test results. The possible father has passed away and we had his sister tested with my daughter and myself.. The combined relatedness index is 0.0491 and the probability of relatedness is 4.7%. The lady that read the results to us said that she has never seen the (probability of relatedness) come back like that. She said that should of came back 0%. What does this mean? Could his sister be my daughter’s aunt? Could he be her father? If so, what do we do next to figure it out?
Identigene says
Hi, Chasity. For an avuncular family relationship test, it’s not unusual at all to be given a probability of relatedness anywhere between 0% to 99%, so you were given incorrect information. Only with a straight paternity test will you get a definitive yes or no for relatedness with either a 99% or higher or 0% probability. The results you were given are inconclusive. If you tested again with a different lab, you would most likely get the same results. Whether or not a test like this is conclusive depends a lot on luck: which genes were shared. What you were told is that the chances of the sister being related to your daughter is 5%. It doesn’t mean it’s impossible, it’s just a low probability.
rogerd says
I have typed below the DNA Laboratory Report.
Conclusion:
“The DNA profile from Child is consistent with having come from an offspring of her Mother and Alleged father.
The DNA profile from Child in this nation’s population is 367,400 times more likely to be obtained if she is an offspring of her Mother and Alleged father than if she is an offspring of a random, unrelated man.”
Only these two statements are in the conclusion. My question is:
Are the two statements enough to say that the Alleged father is the biological father?
TAKE NOTE:
1. Combined Paternity Index either 99.9% or 0% IS NOT INDICATED in the report.
2. There is NO CONCLUSION stating either
“is not excluded as the biological father,” OR
“is excluded as the biological father,”
Please reply to this so it could help us with our existing problem.
Identigene says
Hi, Roger. Although it appears the lab where you tested is telling you the results for paternity are positive, they did not use the language commonly used in paternity-test reports from AABB-accredited labs. I would call and ask them about it.
STEPHANIE says
What does it mean when it says
“Based on testing results obtained from the analyses
of the DNA loci listed, the probability of relatedness is 99%. The likelihood that the alleged relative is the biological
relative of the tested child is 116 to 1”
Identigene says
Hi, Stephanie. It means that the man tested is considered the biological father of the child tested, with a probability of 99% (which is considered conclusive). The chances of another man with the same ethnic background being the father are 116 to 1.
Patricia says
I hope these test are accurate! I’m 110 percent certain that my daughters father is her father. I just been reading through the comments and people saying that they were certain and the results came back otherwise. We read the instructions tell me thoroughly. My grandmother witness us all take the test and she sent them in. I just would be so upset if the accuracy on these test are wrong because I really don’t want to take this man to court or they would put him on child support and I would never want to ruin his life because of a mistake with a dna test reading. He’s a great father the reason for this test is for his peace of mind. This has just been so strongly on my mind from reading comments of other users.
Identigene says
Hi, Patricia. The reason people do paternity tests in the first place is because they aren’t certain…not really. It’s always difficult when results aren’t what people expected. You have to remember that, once samples are at the lab, the testing process for at-home tests are exactly the same as for legal tests, which are accepted as proof of paternity or non-paternity by all courts. Our lab performs thousands of tests a year for courts all across the country and around the world. As long as the DNA samples are from the same people, customers who go on to do a legal test are always amazed to see that their DNA data and the conclusion is exactly the same for their legal test as it was for their at-home test. The science is sound.
Patricia says
That’s so great to know! Thanks for the clear of mind. Her father wanted just a clear of mind as he should. I shouldn’t trust comments because I don’t know the person and history. So I’m put in a better mind set from the information you’ve given me. I highly appreciate your fast response.
Identigene says
You’re very welcome!
Nini says
Hello mines came back as probable paternity as 99.99997 what does this mean because the father of my child think i tampered with the swabs.. omg so retarded…he said that 7 at the end is throwing him off…im so annoyed with this situation….cause he acting retarded as hell.
Identigene says
Hi, Nini. It means he’s the biological father. You can’t tamper with the swabs and end up with a positive probability of paternity.
John says
I just got my daughter’s DNA tested on MyHeritage.com.
I know for a fact I am nearly 100% European, mainly English and German. My wife is 100% Asian, mostly Vietnamese.
My daughter came back as 75% Vietnamese/Chinese, 15% Thai/Cambodian and 10% Filipino. In other words, 0% Euro. So for 14 years, I thought I was the father, but now I’m in shock. I always thought my daughter looked a bit Filipino, but I always though it was a mix of Euro and Asian that gave her that appearance.
Now the question is, is there a chance they mixed up her DNA with someone else? As you would expect, I’m highly disturbed by this result.
Identigene says
Hi, John. I can’t comment on the specifics of test results for a different company, I’m sure you understand. Gene-pool or ethnic percentages for an ancestry test are never a determinant of paternity because those are estimates and estimates only and are for entertainment purposes. If she is indeed your daughter, it may just be that her European genes weren’t picked up by the ancestry test’s algorithm. If you have doubts, the only way to know for sure is to do a straight paternity test which compares DNA profiles, which I highly recommend for you if only because it will give you peace of mind. I wish you and your daughter all the best.
Lynn says
I had an HLA test done in 1990 but was only able to test one potential father since the other was deceased. The results stated 82 – 88% probability the tested person is the father so the courts declared him the father. How sure is this that he is the father and not the deceased man?
Identigene says
Hi, Lynn. Today, that would be considered an inconclusive result.
Lynn says
Thank you for the information. It leaves me with quite the conundrum but after so many years I guess I won’t mess with it. I’d just like to know for medical history – depression, addiction and suicide are strong in the family of the deceased and my son has displayed serious deression and addiction issues – along with severe ADHD that is/was present in both potential fathers. It’s too bad I can’t be sneaky and obtain a samle from the living father.
Emily says
Tested father and daughter DNA test came back 99.999999998 what does the 8 mean at the end?
Identigene says
Hi, Emily. First of all, that’s such an infinitesimally-small number that it’s of no consequence, so no worries! Obtaining a probability of paternity is a matter of math and statistics. Analysts take the individual data points and make a calculation. If there’s one gene where the the strength of the match for the ethnic group of the persons tested isn’t as much as some of the others, then you can get a number other than 9 on the end. But it’s still a match, which is what really matters.
Anon says
I have a question only my daughter and the potential father were tested. Since she is X and he is XY all the numbers In the X Row should be the same since she doesn’t possess the Y right? Out of the 20 only 7 of those numbers match. I’m trying to figure it out as I didn’t take the test so unfortunately I can’t get the information from customer service it’s just not adding up to me
Identigene says
Hi, Anon. If you tested with us, the two sets of data for each genetic marker are not in any particular order and so the father’s genetic contribution for the child may not necessarily be in the X column. What matters is that there is a match with the father at each marker, regardless of position.
Derrick says
I had a dna done about 26 years ago result was 97.99% judge rule me the father. I been paying support every since I want to be release from this. Tell me can I be consider the father. She slept will my brother and a cousin.
Identigene says
Hi, Derrick. I’m not sure why you’re paying support for a child who is now an adult? At any rate, if you want to be released from any legal ruling, you need to consult a family-law attorney in your area.
Chaz says
My DNA Half-Sibling test came back with a ratio of 1.21 to 1. What does this mean? We’re not related? I thought it came back in percentage?
HomeDNA Identigene says
Hi, Chaz. I consulted with one of our PhDs, and this is her response to me:
“Sibships are a little different than paternity. They are reporting a likelihood of the relationship. Reports can only provide supporting evidence of the relationship. If she has a Likelihood of 1.21 to 1– this test is inconclusive and the probability would be around 53%. It is neither supportive or non-supportive of the relationship. Since it is inconclusive, some labs opt not to report a probability percentage because it can be confusing. i.e.. 80% likelihood sounds pretty good, but it really is not. If it had been our report we would have suggested to her on the report that she needs to test additional parties, such as a mother, to help the get more conclusive results.”
Takira says
i recently did a paternity test,when i called to check on the results,they said one of the envelopes weren’t labelled so are they sure they tested the right samples? because i saw the alleged father fill out his envelope.
HomeDNA Identigene says
Hi, Takira. You didn’t mention whether you tested with us or not. I can’t speak for other labs, but in our case, all sample envelopes in a kit have the same barcode, which is scanned throughout every step of the process. So there’s no chance of samples being mixed up.
Aprilsi says
I received my results and it reads “excluded”, which means he is not the father. It states that the This conclusion is based on the non-matching alleles observed at the loci listed above with a PI equal to 0.
How do you know if you did not swab your father’s mouth correctly? When you receive your results will it tell you it needs more DNA samples to give an accurate report or will a letter be mailed asking for a better sample?
My dad is 74 and has Parkinson’s for 20 plus years. My mother is deceased. For years I have always wondered if he was my dad so I swabbed both our mouths, his was a little dried but I swabbed each q-tip for 30 seconds each (just like the instructions said to do). I am not sure if a good sample of my dad was on each q-tip. I did not feel there was a good amount but then again I do. How can I find out if a good amount of sample was given for my dad? I did submit 4 q-tips so hopefully, there was plenty of DNA submitted and my results are accurate.
HomeDNA Identigene says
Hi, Aprilsi. If a report was issued, then it means there was enough DNA on the samples to complete testing. If there hadn’t been enough DNA, the lab would have suspended testing without giving results and asked for new samples.
Scott says
Your website states that for there to be a paternal relationship there has to be an allele matching between the alleged father and child on EVERY DNA marker that was tested. Well my test came back 99.99% probability of being the father.But one of the markers didn’t match. The report said there was a gene mutation. So how do they determine that high of a probability when there is one marker not matching?
HomeDNA Identigene says
Hi, Scott. The analysts take into account the prevalence of that genetic mutation within the ethnic group of the alleged father (or child) when making their calculations for paternity. So if it’s a mutation that’s widely seen in that population, it doesn’t count “against” the man being considered the biological father.
Scott says
Thank you for explaining that
HomeDNA Identigene says
You’re welcome. Anytime!
Scott says
I have one more question. Is an uncle to far removed to cause a false positive on the paternity test? I know a brother can cause a false positive but could an uncle?
I had my test done with DDC it came back 99.99% and a CPI of 19,000
Thank you
HomeDNA Identigene says
A child only shares 25% of their DNA with their uncle, so the chances of that making a difference in your test is extremely small. Ideally, the uncle would test also and tell the lab ahead of time about the biological relation between him and you.
Scott says
Thank you for the explanation
Diane says
Should these “alleys” listed in the results have to match number for number to determine the paternity? They don’t match but are pretty darn close, yet the results determine zero probability of tested being the father. Thank you.
HomeDNA Identigene says
Hi, Diane. The numbers are called alleles and represent the genetic information at that particular location on the gene. They’re not quantitative. For example, it cannot be said that if one person has a “4” on a locus and someone has a “5,” that their genetic information is “close.” It’s just not how it works. In order for a man to be considered the biological father, he and the child must match at every genetic location tested (usually 16-20 or more locations). There are exceptions made for genetic mutations, and those exceptions are taken into account when doing the analysis.
Tony says
If the other potential father is my brother and his sample is not included and they have to do “extra testing” how many markers are tested ? Will this give a definitive answer to paternity? How long does this test take?
HomeDNA Identigene says
Hi, Tony. There is no set amount of extra markers…whatever the lab needs is tested in order to get conclusive results. Ideally, both men would test. If that’s not possible, we can get conclusive results with one. If only one brother is tested, the mother should definitely include her DNA and it’s absolutely essential that the lab be notified ahead of time that there is another possible father and that he is the brother of the man being tested. This way, the lab can take this knowledge into account in its analysis and test additional markers, if necessary. Once all samples are received at the lab, results are posted in 1-2 business days.
Alanna says
Hi,
My dna test results says 99.9999999998%, what does that mean? I am asking because both potential fathers are 1st cousins, their mothers are sisters. Only one of them has been tested.
Also, at three different loci me, my daughter, and the alleged father all show the same allele size numbers. For example under one of the loci it says 13 for the first allele size and 14 for the second allele size, and that’s for all three of us.
HomeDNA Identigene says
Hi, Alanna. In short, the results mean there is a 99.999999998% probability that the man tested is the biological father of the child tested. The two possible fathers being first cousins is too distant a relationship to make a difference. As humans, we share a lot of the same DNA, so it’s not unusual at all for all three of you to have the same allele size at one or more locations. You and I would probably match at several, even though we’re unrelated. What makes the difference in a paternity test is if, barring any mutation, the possible father and child match one allele at every single genetic marker tested.
Jessica says
My friend did a paternity test and it came back 99.9993% however we still think its his bothers, only him and the baby were tested, not the mother or his brother. Is that a possibility, that his brother can be the father and because they are brothers we got a false positive?? Help please.
HomeDNA Identigene says
Hi, Jessica. Although the possibility is slim, it exists. This is why it’s absolutely essential in these types of cases to either: (1) test both men, or (2) test just the one brother, but let the lab know ahead of time that the other possible father is the brother of the man being tested. This way, the lab can take this info into account when performing their analysis and test additional markers, if necessary. The mother of the child should also be included in testing. I recommend that your friend test again.
Jessica says
Okay thank you. I did call the lab as well and they said it could absolutely be a possibility because only my friend and the baby were tested and nothing was noted that his brother was a possible father as well. And of course they recommended that the mother be tested as well to make sure the results are accurate. Thanks again
HomeDNA Identigene says
You’re welcome!
Hannah says
So 8 mismatches out of 20 markers tested means he IS EXCLUDED right?? It says he IS EXCLUDED on the report 0% CPI and 0% POP…..I just want to hear it, well in this case read it to get an extra confirmation…..
Did the testing through you guys with a third party and all I can say is if my sample hadn’t been included instead of 8 mismatches it would have been 6 as some of his alleles matched with the child’s but with my DNA included there were those 8 mismatches confirmed and I’m extremely pleased, I finally get to breath!
HomeDNA Identigene says
Hi, Hannah. From what you describe, the man tested is excluded. He is not the biological father.
Niece says
Hello I had a test done by child support twice for whatever reason they didn’t use the first test because they had been done by two different labs we both live in different states but anyway my daughter is identical in every way shape and form to the man tested the result of the 2nd test given says 0% probability and I know exactly who I slept with and when I don’t understand how that result is true and child support won’t redo the test all of my children look like their dads and I’ve always been 200% positive of my partners so why is this time any different how could she look like from skin color to hair texture color hair line features and all and my results be 0%
HomeDNA Identigene says
If the test was ordered by the state, then DNA collection was witnessed and you can absolutely trust those results because it’s highly unlikely that any fraud could have taken place. Physical traits are never absolute proof of paternity, which is why courts rely on DNA testing. It’s proven science that’s unbiased, but it doesn’t always give the results people hoped for or expected.
DeAnn says
will my dna test show if I have ever been pregnant? I have no children
HomeDNA Identigene says
No, it does not provide that kind of information.
Jessica says
Hi ,
My husband had a test done a few years back in court , but I’m not understanding the numbers ? The results came back 97.8888 percent but isn’t it suppose to be 99.9999? I honestly feel as if he should take another test . Do you think he should’ve been excluded ?
HomeDNA Identigene says
Hi, Jessica. You didn’t mention how many years back your husband tested, but it must be at least 5. With today’s technology, an inclusion should be at least 99.9%. A 97.8888% probability would be considered inconclusive, but keep in mind that it’s not an exclusion. If possible, he should do another test for peace of mind, if nothing else.
Rita says
Hi, My husband was tested by ya’ll a couple of weeks ago along with a woman who was told all her life that he was her biological father. The results showed 99.998% that my husband was her father. No big deal….BUT, my husband’s father was told all his life that he was adopted…So how can my husband be her father if his father was adopted by his father and they don’t have the same bloodline. We are all so confused. Is there a DNA test that can be performed to see if my husband and his siblings are or are not of the same bloodline (DNA) as their grandfather (that supposedly adopted their father) or are they of different DNA. Both my husband’s father, grandfather, grandmother are deceased. The only living relative on my husband’s father’s (sister) (grandfather’s side (daughter) that is from his lineage is a sister / daughter.
HomeDNA Identigene says
Hi, Rita. The paternity test showed that your husband is the young woman’s biological father. That’s all it said. It doesn’t have anything to do with long-term bloodline. Whether or not your father-in-law was adopted doesn’t have any bearing on the paternity test.
Calex says
What does it mean when it states “this genetic analysis excludes at least 99.99% of Hispanic men from paternity” I understand what this saying mean just not in this text- For example is my child of or not of Hispanic genes???
HomeDNA Identigene says
Hi, Calex. A paternity test does not specifically identify so-called “Hispanic genes” or “Black genes,” or anything related to race in the tested parties’ profiles. A calculation of paternity is made based on the racial identity stated by the customer. So if you stated you were Hispanic when ordering the test, the lab has based its findings on that information and says that there is a 99.99% probability you are the biological father compared to other unrelated, non-tested Hispanic males.
David says
Hello. I had to have a dna test against my two younger boys, requested by Department of Community Services on behalf of the childrens mother. So i done two separate test (1 test against each child), 4 days later DOCS called me and told me i was the father and said the result was 97.897%…. i then asked what the other percentage result was for the other child and they said it was exactly the same?? Im confused at all of it as i then asked for the paper copy of my DNA test results and the said they couldnt supply me with them because they misplaced them??? What does all this mean?
HomeDNA Identigene says
Hi, David. You need to start asking DOCS questions. If the situation is as you describe, you need to protect your rights.
> If they can’t locate the paper copies, will they pay to have the test done again? You are entitled to see the reports.
> Who did the DNA testing? With today’s technology, a reputable and legitimate laboratory would never issue inclusionary results with less than a 99% probability of paternity.
Do you have a family-law attorney or caseworker looking out for you, David? You really need one.
Sarah says
Hi, I received the results from my test yesterday and I have a feeling the swabs could have been contaminated unintentionally. I did my swab at night, sealed the envelope when I went to mail my sample the envelope had come unsealed. I taped it up, put it in a packing envelope and mailed it to my potential father who then mailed the results to the lab. Could this have affected the test in any way, as there are so many similarities between not only my potential father but his sister as well? Thank you

Hi, Sarah. If a swab is contaminated in any way, the lab would have caught it at the time of testing and requested new samples. Seeing as you didn’t have complete control over the swabs between your house and the lab, though, you have no way of knowing if the possible father submitted the swabs you sent him or someone else’s DNA. This is something to consider. If you think this might be a possibility, I suggest you retest, but this time do a legal test with court-admissible results. With this type of test, DNA collection is witnessed, so you can be sure the DNA submitted for testing is for the correct people.
