What do my paternity test results mean?

What Do My Results Mean?

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

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%. What Do My Results Mean? | DNAtesting.com 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). What Do My Results Mean? | DNAtesting.com

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.”

      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!

  1. 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!

  2. 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!

  3. 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!

  4. 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!

  5. 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!

  6. 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.

      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.

  8. 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!

  9. 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!

  10. 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.

  11. 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: https://dnatesting.com/i-got-different-results-from-a-different-lab-how-is-that-possible/

  12. briane says

    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!

  13. 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!

  14. 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!

  15. 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!

  16. 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!

  17. 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!

  18. 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.

  19. 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…

  20. 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!

    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.

  22. 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!

    • 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.

  23. 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?

    • Identigene says

      Hi Christina,
      Thank you for your patience! Our lab does test for gender. If the alleged father sample is tested to be a female sample, our lab will request a recollection to make sure all correct samples are collected. We highly recommend having the collection of the DNA witnessed as well as when the samples are sent off. To prevent mistakes, whether intentional or unintentional, we recommend having a court-admissible test done. Court-admissible tests require a disinterested third party to witness and administer the test. I hope this information helps.

  24. 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!

  25. 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!

  26. 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.

    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

      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!

    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!

    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!

  31. 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!

  32. 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!

  33. 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!

  34. 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.

  35. 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.

  36. 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.

    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.

  38. 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.

The probability of paternity for inclusions must be higher than 99%. The probability of paternity for exclusions will show as 0%.

      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.

  40. 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.

  41. 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.

    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:

    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?

      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.

    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.

      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.

      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.

    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?

      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.

  49. 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

    • Meisha says

      Hello Lakin,
      The DNA profiles in paternity testing consist of DNA markers 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.

      We do strongly recommend including a sample from the biological mother because there is a rare chance the results can 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 the percentage on a test comes back as 0.00% or 99% – 99.99% then that is a conclusive answer and we would not have needed the mother on that specific test.

      The web link below will provide you with additional information about why the biological mother is sometimes needed to complete testing. 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.

    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.

    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.

FROM THE BOTTOM OF MY HEART PLEASE HELP ME TO KNOW IF THE FATHER IN THIS DNA TEST RESULTs I HAVE PROVIDED IS ACCURATE the paper said he excluded. Is he really “EXLUDED” or “NOT-EXLUDED” or is he “THE FATHER” or “NOT THE FATHER” Thank you and hoping to hear back from you.

    GOD BLESS.

      Thank you for contacting Identigene. 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.

    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.

    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.

    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.

  58. 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.

  59. 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.

    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.

    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 https://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 “alleles”). 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.)

    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

    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.

      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 888-404-4363 and we will be happy to assist you.

    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: https://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.

    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?

      We would be more than happy to assist you with understanding your results. This would be easiest to address by calling us at 888-404-4363 and talking to a DNA consultant over the phone so we can look at your specific report. We look forward to hearing from you.

  71. 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%?

    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 “phenotype”), the DNA analysis of their genetic profiles (we call this “genotype”) 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 (“phenotype”) to analyze our actual genetic biology (“genotype”).

      If the biological father was excluded as you described, he would be definitely excluded from our point of view. Genetic chimerism (or “congenital chimerism”) 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.

    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.

    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

    • Meisha says

      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.

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, and the accuracy is 100% 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.
