After DNA samples arrive at the laboratory, IDENTIGENE paternity test results are released in two business days. And they may not always be what are expected!
Sometimes when results of DNA testing show 0% probability, meaning the alleged father is not the biological father, there are some loci (or markers) in the report that do match between the alleged father and child. Participants may not understand why this occurs in DNA testing if the two participants aren’t related, so here’s a quick overview of how this happens.
Basics of a DNA Paternity Test
In paternity testing we generate DNA profiles using Polymerase Chain Reaction (PCR) process. PCR is the process of taking a small piece of DNA and making many enlarged copies so it can be measured for a paternity test. In the DNA profile analysts look at 15 specific loci or markers (location on the DNA chromosome for a gene) which are then reported on the DNA test results. The profiles are compared for all participants to determine if the alleged father and child match at all 15 markers or locations. Because the child gets 50% of its DNA from the biological father and %50 from the mother, there must be a match at all loci for the alleged father to be considered the biological father. If there are any mismatches, then the alleged father will be excluded, even if there are a few matches.
Loci Matches on Paternity Tests
A few positive matches can happen in DNA paternity testing because there are specific markers that are common among the population. When you look at the profiles on a paternity test, and there are some matches, this does not necessarily mean the participants are related. Each matching loci between the alleged father and child is calculated into a paternity index which measures the strength of a genetic match. This indicates how common that marker is in the population. Sometimes markers are very common so people that are not related may match at certain locations.
As stated above, in order to be a biological parent there must be a match at each location (with the rare exception of one mutation, which is a change in a gene passed from parent to child). If a possible mutation is identified, additional markers will be tested.
This is why you may have some locations that match on a paternity test but paternity test results nevertheless indicate the alleged father is not the biological father.
Robin says
That whole thing with all the markers matching for them to be the father does not make sense. I just got a dna test done with my son and his father for court purposes and alot of the markers didnt match my dna. So shouldnt he still be the father when most of the markers match his? There were more markers that matches him then me. I feel that this paternity is not really 99.99% accurate because he is the only man i have been with since 2010 and our son is 8 months old. Please explain.

Shae says
Hello im currently going three the same thing here and now it made a problem bad for me. Me and the allaged father not even speaking to one another and i know for sure the whole year i was messing with him it was just us…
Jennifer says
My husband was tested years ago for a child, and he was determined to be the father. Problem is, his dad slept with her too and he was never tested. The test was done for child support reasons, so I’m sure it’s accurate. My question is, could the child be his fathers? I know I don’t have exact numbers or the test results, I’m just asking, generically, if there is a chance his dad could be the father?
Identigene says
Hi, Jennifer. It is most likely accurate, especially if the lab didn’t make a notation on the report that there is a possibility that a different man who is a close relation to the man being tested could be the father. This is why we always insist that, if a close biological relative of the man being tested could also be the father, that the lab be notified so that they can test additional genetic markers if necessary. If possible, it wouldn’t hurt to have the dad tested as well, since this is nagging at you.
patrick says
does 99.99998 mean im the father for sure?
HomeDNA Identigene says
Hi, Patrick. It means you are the father with a 99.99998% probability. So the chances of your not being the father are infinitesimally tiny. It can only be 100% probability if every man in the world with your ethnic background were also tested…which obviously isn’t possible.
Rihannah says
Actualy my doughter ws made a dna and the alerged father matches 8and the rest dont match and the other man was tested and all wea negative and now my doughter is 5 months and am hving dificulty so i wana know the father of my doughter can u help mi pliz coz the docter said she needs my blood to test and match wether the rest that didnt match are mine what can i do help mi pliz
Admin says
Hi, Rihanna. Is there a possibility that a third man could be the father? It does not seem from what you told me that either man tested is the father.
Kathy says
My son is now three yes old I was conceived on August 26 2012 and I got with my ex In August can’t remember what day it was I think it was on the 17 or 20 I had heard that if I was conceived on 26 the sperm can life up to 7 days until the sperm gets inside the egg right so it happen on the 20 if u count back 7 days I was already seeing him after my ex left I was sad I got with someone in September and later found out in October 1 I was 5 weeks and one day so is that mean that I was already a mouth in September :/ my son was born in May272013 and I did a DNA test with my ex and 9 didn’t match so it said that he wasn’t the farther I always had a feeling that the swap was tempered with someone he is the navy and he did the test over there in Japan I don’t know if the other guy is the farther cause he is in hiding right now but at first he had told me straight out then and there that he isn’t that he could be when I had told him in October that I was pregnant I wanted to know the truth was the Dan test tempered with I counted the mouth my son was born started with September and its 9 months I’m really confused here
Admin says
Hi, Kathy. When DNA collection is not witnessed by an impartial observer (third party), then it’s possible that a man could submit his buddy’s DNA instead of his own in order to influence the outcome of a paternity test. If you want to be absolutely sure the DNA submitted for testing is his and if you plan on using the results to ask or child support, the court can compel a man to take a legal test (one that’s witnessed). That might be your best option and it would certainly erase all doubt. Good luck!
Kk says
5 weeks pregnant as of oct 1st meant u conceived in September. They count your last menstrual cycle as conception date. You were technically only 3 weeks pregnant when you found out. Ask a doctor to help establish a more acurate time line and explain how they count your period even though you were not actually pregnant during that time.
Lynn says
I just got my sons DNA results back today and it said one of the markers didn’t match but it was 99% accurate . The DNA place asked if the other male was related to the man that was tested meaning are they brothers or 1st cousins. Does this mean the person who was tested isn’t the father?There was also a two week Gap in between both males when I conceived . I’m so confused please help.
Admin says
Hi, Lynn. Is there a possibility that someone else closely related to the man tested could be the father? If so, I highly recommend that he test too. Without having your test results in front of me, it’s impossible to comment on specifics. You should probably call the lab you tested with for clarification.
Jessica says
I do not have the test in front of me and granted it was 13 years ago but here is my story and hopefully u can Answer questions i have had for years… i was with my ex 14 plus years ago the night we well u know we ended up breaking up afterwards and aprox 2/3 weeks later i was raped…aprox when my son was a yr and a half i got on assistance that demanded paternity testing for the child i gave my exs name and stated the other possibility situation but was pretty certain it was my ex when i attempted a time line..my ex was in prison so they did his test there and they took me and my babys shortly my ex got out of jail…came over to my place looked at pics of baby and instantly said the baby was his pointed out simularities of him at that age…the test came back negative neither of us understood and were disappointed but the markers were like mom 29/28 dad 29/32 baby 29 or like 3 markers but still had more in common with his markers then with mine but still not the father…we moved on … twice my ex has came back into my life over the past 14 yrs and continued to say how he thought the test was wrong and still vould be his kid as my son continued to look more like him when he was that age…i have not seen my ex in 6/7 yrs but yet when i mive back to the town i met my ex in i have had ppl who do not know me or my son and ask me if he was my exs??? Due to simular looks was given a recent pic of my ex to compare too and besides my son having blue eyes and my ex having brown eyes and a slight difference of the nose (“its a blend of both ur noses”) they look the same the eye shape the chin the cheek bones and jaw line even the exact same hair color! The same “look” in poses in pictures..i thought for many years me “seeing my ex” in my son was in my head just hoping due to the other possibility but i moved on rationalizing those results and not the father bold print starring at my face but 14 yrs later the things ppl have said/asked me since i moved back has me once again questioning..should i request a new test could something have gone wrong could he actually be his father?? Or should i trust the result of that test and get over it like i have talked myself into so many times? I am willing to accept that my own thoughts on this may be in my head..but how do i get passed strangers seeing such close simularities with the 2 of them?
Admin says
Hi, Jessica. Looks are never an absolute determinant of paternity, especially when two people are the same ethnicity. For example, my niece looked exactly like I did at age 7, but she’s adopted and we don’t share a biological relationship. Sometimes people look similar when they’re not related. That being said, if this is really bugging you, then what’s the harm in doing another test, just to put your mind at ease? It sounds like your ex would be willing. Keep in mind your child is a teenager and you’ll need to explain the test to them.
jocely says
Hello Jessica,
I’m in a similar situation of yours. With me being the “child” I am curious. did you get another test done? Did you find some type of way to confirm if your ex is the father ?
Somorah says
So I got a DNA test n got the results back and it stated 99.97 so what does that mean?
Identigene says
Hi, Somorah. It quite simply means that there is a 99.97% probability that the man tested is the biological father of the child tested. That’s a very strong result that would hold up as proof of paternity in any court of law
Dee says
Hi i had a paternity test done the test came back matching all 15 markers,bt i(the mother) wasnt tested,,, does that mean he is the father ?
Identigene says
Hi, Dee. If the probability of paternity for the report you were given shows a 99% or higher probability of paternity (usually 99.9% or higher), then the lab would consider the man tested to be the biological father, yes. In most cases, the mother’s DNA is not needed for a straight paternity test, but in rarer instances it can confirm results. Hope this helps!
Angela says
Hello I am wondering about a test my daughter took with who I know is her father. The test was done from a mobile testing unit and came back matching 11 out of 15 loci with 1.0 % or over in all 11. I was not tested with them. My daughter has a chromosome disorder and is missing some chromosomes and some are ring chromosomes, there was no percentage of likeliness of paternity on the test results given to me. But after speaking with different doctors and some research I am finding out (based upon the numbers from the results) that it equals out to 98.7% chance of paternity. Could this be because of her chromosomes or maybe because I was not tested along with them? I have never met any males in his family and so I know it is not a relative and he was the only person I was with.
Identigene says
Hi, Angela. I asked one of our PhDs to answer your question, and this is what he said: “Chromosomal abnormalities typically do not affect the results of a paternity test. It would help to have the mother tested along with the alleged father and child. As it stands now, the test results appear to be an exclusion, but we could look at the test results if submitted. A 98.7% is below the minimal AABB threshold for an inclusion of paternity.”
martha herring says
My test result came back 0% possibility of paternity. My question is that there was 8 locus that did not match father and 10 matched with son , or appear to match not sure, but results had a number greater than 0, My concern with these numbers would he still not the father ?
Identigene says
Hi, Martha. With a 0% probability of paternity given, regardless of any individual numbers that may happen to match, the man tested is not considered to be the biological father of the child tested. Hope this helps!
Becky says
I just had a DNA test done for my daughter and alleged father ..he had 10 matching markers and 5 that didn’t match.it says that he is not the biological father ..is that 100% accurate
Identigene says
Hi, Becky. 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.
Becky says
Thank you for the reply.. I was tested as well just wasn’t understanding it all..also would alcohol and the fact the he took several shots of liquor minutes before the test have any effect on the test.
Identigene says
No. Drinking alcohol won’t change the DNA; it can only possibly affect the quality of the sample. Since a report was issued for your case, the samples were fine for testing.
Jill says
I’m also confused with this. The alleged father had 12 marching inclusions. And report states he can not be ruled out as the father. Does this mean since he marched 12 he is the father? Is it worth submitting another swab from the father I think is. If he has a higher inclusion rate than he also can’t be excluded either? It it common to send another sample of the first swab showed can’t be excluded???l. Is there possible the new swab will match more than 12??
HomeDNA Identigene says
Hi, Jill. If the report states he cannot be excluded, then he is considered the biological father of the child, with whatever probability of paternity and paternity index data were given. That being said, 12 is a low number of genetic locations for a paternity test.
Sarah says
Hi, I did an at home paternity test about 5 years ago on my child. The alleged father lived in a different state so we had his shipped to his home. We only tested the child and the alleged father, due to not having the money at the time to test me as well. The conclusion said 0% probability, however they tested 15 different strands of Loci and only 3 were not a match. They were, however very close in numbers- child: 12/18 father: 16/17, child:10/11 father: 12/13, and child: 22.2/26 father: 22/23
This has been bothering me for years now because after he got the results he just said “hope this puts your mind at ease, especially knowing that I paid for it and did it and it has come back negative now”, then he goes and blocks me all every social media site. Could it be possible that he had a sibling do the test for him and that is why those three markers came back so close to each other? Or should I try to do a test on myself now so I can see which markers are a match to me? Will that still work, since it was over 5 years ago? I am trying to decide if I need spend the money on another test or if I should just except that he is not that father.
Any help is appreciated.
Thanks.
Identigene says
Hi, Sarah. Since the DNA collection wasn’t witnessed either by you or by an approved DNA collector, there is a possibility the man tested could have submitted someone else’s DNA as his own, yes. I suggest you test again (the court may compel him to if he refuses), and this time pay a little extra to get a test with legal, court-admissible results. An independent and approved DNA collector supervises all aspects of DNA collection, including mailing, checks IDs, takes participants’ pictures, etc. so that there is no chance of fraud. If you want more info about legal testing, give us a call at 800-344-9583.
Kim says
I just had a paternity test done and only 13 loci were tested between the father and the child and out of that 13 10 were a match and 3 wasn’t , I wasn’t tested either as the mother , the alleged father was excluded as being his biological father. Could you explain this to me please
Identigene says
Hi, Kim. First of all, a respected, accredited lab will test at least 16 loci. It only takes one mismatch for a man to be excluded as the biological father. The fact that he matched the child at 10 out of 13 is not that unusual.
London says
My daughter is also 5 months well was 4 at the time and we didn’t wait an hour and she had a bottle and he also smokes cigarettes
Identigene says
The age of the baby doesn’t affect the test. If the samples had been contaminated by formula or cigarette residue, the lab would have suspended testing and asked for new samples. Since a report was issued for you, then the samples were OK.
London says
Out of 20 locus 14 were matches, 3 only have 3 or 2 alleles and 3 were not matching but we’re close in numbers, I wasn’t tested as the mother and I don’t know if he did the test right and my daughter are right before taking it
Identigene says
Hi, London. Having many loci that match is not unusual, even if the father and child are not biologically related. As for numbers being “close,” the numerical values don’t mean anything…they’re just for identification purposes. If the correct samples were submitted, you can be confident the results are correct.
Karissa says
Hi we had a test done and the company we went with tested 20 locis and two of them FGA And CSF1PO were not a match. But they said the probability of paternity was still 99.999999% that on those two genes there was more than likely a genetic mutation of the genes. Is this correct? Does this still mean he is the biological father??
Identigene says
Hi, Karissa. Without seeing your actual test report with the PI (paternal index) at each locus, I can only take a best guess. It is common to have a mutation at one locus and less common to have two. However, it’s still possible to get a 99.999999% probability of paternity when calculated for the mutations. So if the lab is accredited and well-regarded, you can trust the results. And yes, with this high probability of paternity, he is considered to be the biological father. Hope this helps!
Tamiyah says
If I was 6 moths pregnant April 1st, 2016, can you tell me what day I conceived? Wouldn’t it be October? My due date was July 15th and July 22, 2017. Also in the DNA testing result, say the mother has more matches than the allegened father but the allegened father has some matching markers, can you please explain to how a person is not the father when they have matching. More than 9 matches to be a little more specific.
Tamiyah says
2016*^
Identigene says
Please consult a doctor about your conception date. As for your other question, it is not unusual at all for there to be markers matching, even if the man tested is not the father. You and I probably have markers matching…it’s the way genetics work. But for a man to be considered the biological father, all markers must match.
Tamiyah says
If I had my child July 17, 2016 and my due dates were July 15, 2016 and July 22, 2016, does that mean that I conceived in October? I was with an ex in October but started talking to my boyfriend in November. April 1, 2016 I had found out that I was 6 months pregnant. So I don’t know if it could be by my ex or boyfriend. Me and my ex took a DNA test at home. I had all markers matching and he had more that 10 markers matching. After he took me and my son swab he left. Is it possible he let someone else take the test that’s related to him? He made me and my son do 3 swabs when there was 4 swabs for each person. Are the names supposed to be on the results paper with a DNA workers signature? What he showed me was a paper with just the results. No name, date, or signature was on the paper. Is there a possibility it could be fake?
Identigene says
Hi, Tamiyah. Without seeing the report you were shown, it’s hard to say if it was faked. If you did an at-home test, there’s no way we can guarantee that the DNA we tested belongs to who the participants say it does. So there are no names or signatures on those reports: participants are simply assigned names. There should be a date, however. When customers choose to do a legal, witnessed test, the report has names and signatures.
Stuart says
Hi I’m Stuart. I took paternity test which out of 12, listed only 3 matched for me, 6 matched for the mom and 3 didn’t match neither of us. The result of the test stated that I am 99.99998% chance of being the biological father. I am very confused about the results because after studying how to read the results, I perceived that the child had to receive a number to match from each parent. Not only do I only match 3 of 12, at times, the mom matched neither number as well. How did the result indicate that I am the father and how is it that the mom nor myself does not match some systems? Please give me a logical answer.
Identigene says
Hi, Stuart. Chances are good that you’re not interpreting the data correctly, but without seeing the report myself, I really cannot comment. You should contact the lab where you tested for clarification.
Lizha says
Hi I’m lizha, I’m married have 2 kids, my daughter look like my husband,my son look like another person. But that person live with us more than 4 years, but he always blackmailing me and he said, my son is his son. But I never physically relationship with him, if I not how can is possibly and he blackmailing and 100% he said it’s his son, if I go patternaty test, if positive what can I do? Because I think may be he gave some unconscious drug and he used physically but I don’t know anything please tell me what I do for this problem?thanks
Identigene says
Hi, Lizha. Physical looks are NEVER an absolute determinant of paternity. It is very possible (and it sounds like it’s likely), that your husband is the father of both children. It just happens that only one displays more of his looks. I look nothing like my mother, but that doesn’t mean she’s not my biological mother! You may want to contact a lawyer to see if it’s advisable to do testing, since this man is blackmailing you.
Andrea T. says
Are sibling DNA tests as accurate as paternity DNA tests? My sister and I had a sibling test done to determine if we both share the same father. Only 13 of 20 markers were a match so we were listed as half siblings and not full. If we get 50% of our DNA from our mother and 50% from our father, should those numbers not have been higher?
Identigene says
Hi, Andrea. The results of a paternity test always trump those from a relationship test, like a sibling test. You and a full sibling only share 50% of the same DNA, so the numbers you gave are not unusual.
Teresa says
I had a test done and it came back 13 out of 15 matched. He had drank alcohol right before the swab test and was doing drugs as well. Would that have altered the test? I would hate to get his hopes up again. He has been sober for many years now. Should we do it again??
Identigene says
Hi, Teresa. Alcohol and drugs don’t change the DNA itself, but if he drank right before testing it could affect the quality of his DNA sample. If that happens, the lab suspends testing without issuing results until new samples can be obtained. Since you were issued results, the quality of his DNA wasn’t an issue.
Courtney says
Hi, I recently got results back from a paternity test and it showed that my son matched all markers with me and 8/15 with his alleged father…. I don’t understand it, he was the only man I was with and my son is the spitting image of this man! His eye shape, nose, ears and build seem to match his alleged father they both even have a weird cow lick in there hair just on different sides… I know you say appearance is never accurate for determining paternity but I’m just struggling to understand it all.
Identigene says
Hi, Courtney. Are you absolutely sure he submitted his own DNA? Did you witness the entire process from swabbing to mailing? If not, there’s always a chance he could have submitted someone else’s DNA instead of his. You may want to consider testing again, but this time doing a legal paternity test where all steps are supervised by an impartial witness. That way, you can be sure the DNA is his. Results from this test are court-admissible too, which is a bonus. You’re welcome to contact us and we can make all the arrangements for you: 800-344-9583.
Courtney says
Well that’s the thing it was legal test, but I will be having it redone and I will be there to witness it this time. If it comes back the same then I just don’t know, they look so alike it’s not even funny
Courtney says
I’ve also noticed that when you swap ‘mothers’ dna Results for ‘childs’ results that it then only comes up with 3 mismatches to the father….. I am still very confused though :/
Curious says
Hi Courtney…. How did the second test go? Curious because I have a similar situation with my alleged father and I…
lesley says
why are there 4 swabs
Identigene says
Hi, Lesley. We want to make sure that the lab has enough DNA to run the test twice to confirm results.
c says
I am wondering -if a DNA test came back 99.9% chance that the man is the father – but im still having doubts is it a good idea to test the other male as well? or is there just no way ?
Identigene says
Hi, C. That’s an extremely conclusive result and no need to doubt.
lili says
4 mismatches out of 20 loci. can this still get positive result?
Identigene says
Hi, Lili. Since a positive paternity result despite a mismatch is caused by a genetic mutation, having four mismatches makes it extremely unlikely to get a positive result.
LostIn NY says
Is it possible for a child to look like one man but have another man DNA? A DNA test was done in family court. The man that took the test is light skinned and so am I but my son looks identical to my boyfriend at the time. He is dark skinned with the same birthmark as the man daughter. Is it possible for a child to have DNA from one man but look like the other? I need to know.
Identigene says
Hi! Since you did a legal witnessed test, you can be sure that the results were for the light-skinned man. The man who was tested may simply have genes for darker skin in his background also.
Jen says
Hi therei had a maternity test done with two separate companies one came back 99.99 positive and other came bk from a different Company as 99.999988 are they both positive results the first company tested 22 loci and the second only uses 16 je
Identigene says
Yes, those are both positive conclusive results.
Jen says
Ok thankyou why would one be 99.999988 and other be 99.99 I thought they had to be 99.99 isnt 99.999988 lower I’m confused
Jen says
Oh and also one of paternity index’s had a 0.76 is that still a match??
Identigene says
No, they’re essentially the same number. One is just specified to six numbers after the decimal and the other is not. No worries!
Jen says
Awww great so I can be confident they are both positive results I only used mine and my sons dna didn’t use the dad’s as needed a maternity test done would I need to use dad’s dna to make the result any more accurste
Identigene says
Jen, are you trying to use maternity test results for paternity purposes? You can’t do that. The only thing a maternity test tells you is whether or not the child belongs to the mother. In order to determine paternity, the dad needs to test with the child.
Jen says
Noo I don’t mean that I’ve already had a paternity test done with the dad came back positive u had a maternity test for my own personal reasons and that cake back 99.999988 I was wondering if I had actually added the dada dna also to my maternity test would have the outcome been more conclusive as in would have I had a higher result
Identigene says
That really depends on your individual data.
Jen says
I don’t understand what u mean?? Could you explain further
Identigene says
Just like the mother’s participation can often strengthen a paternity test, the biological father’s participation may also strengthen the results of a maternity test, but not always. It depends on your DNA profile and the genes you inherited from each parent. Your results are as conclusive as they can possibly be…unless every woman in the world with your ethnic background is also tested, the results of your maternity test can never be 100%.
Jen says
I see thankyou for explaining so my results are a very high probability then?? So with a maternity test are the results still accurate even without the dad’s dna samples, Just wanted to double check as these dna tests are hard to understand
Identigene says
Yes, they can be hard to understand. It’s because we are required to use legal language. Your results are an extremely high probability and are still accurate even without the dad’s DNA samples, yes. This article on the website for our parent company (DDC) might help you understand results better: https://dnacenter.com/blog/understanding-paternity-test-results/
Katie says
Hello my son had 2 dna test now both dna numbers on both test are completely different. Does this mean one of the men have got someone else to do the dna testing. I spoken to the lab and explained everything she wouldn’t help I could have access he had all the details not me I wanted to find out why it took 3 weeks for a dna to be done when it was only meant to take 7 days. I Evan asked for online access he wouldn’t give it me it took me a year to get the test off him. I wanted to find out if he replaced the dna swaps in between the test as we both done it in front of each other but he posted it off. So I explain to the lab about the numbers on the tests I said does that mean he got someone else to do the dna she said yes you need to talk to him your self which I can’t because he blocked me. so does that mean he tampered with the testing ? Thanks
Identigene says
Hi, Katie. If I understand you correctly, your son’s profiles were different on the tests? If the data that is supposed to be your son’s is different for the two tests, then yes, it can safely be assumed that somehow the test was tampered with.
Katie says
Yes both profiles is different that what I thought he tampered with it. I will go through the courts now for one. Think he done this to get out begin a father thanks again.
Identigene says
You’re welcome, and good luck!
Christina says
So I’m not sure who the father is of my daughter and neither men want to take the test. I have one who insist she is his and another who just don’t want to know. I have done a paternity test with one of the men before from my other kid. Can I test mine and my daughters DNA and then compare the numbers to old DNA results to the fathers to see if they match?
Identigene says
Hi, Christina. It really does require the analysis of an expert to determine for sure.
Amanda says
What does 9 out of 15 markers mean?
Identigene says
Hi, Amanda. I need more context to be able to answer your question. Are you trying to say, what does it mean if 9 out of 15 markers match in a paternity test?
Amb says
Hi, I just got a copy of my paternity test results and the alleged father matches on 12 markers, but does not match on 14 markers. I understand that In order for the father to be a match, it has to be the same on all markers. My question is, would it make a difference if we were to do a legal test that includes the mother versus the at Home kit like we just did? Or should I rest assured that this an accurate result? Thank you!
Identigene says
Hi, Amb. That’s a great question! The testing process in the lab is exactly the same for a home test as it for a legal test. What’s different is how the DNA was collected. If you’re absolutely, perfectly positive that the alleged father submitted his own DNA (and not someone else’s) for the home test, then the results for a legal test will be exactly the same, whether the mother participates or not. If you were issued results by the first lab, then the mother’s DNA was not necessary to obtain conclusive results.
Jenn says
Hi there not sure if my other message came through on one of the paternity index it was 0.76 why was this number so low compared to the rest
Identigene says
Hi, Jenn. The paternity index number for a particular gene locus is determined statistically, based on ethnicity. So it may just be that, for that particular gene, the strength of the match isn’t as high as the others. No worries!
Jennifer says
Ahh i see :) so even though its 0.76 its still a match?? Wat number would it be if it wasnt a match
Identigene says
It would be 0.0
Jenn says
Aww great thankyou so 0.76 is a match
Identigene says
Correct.
Kate says
Hi, my son’s paternity test result show that only 7 out of 21 loci match. Is it possible that the rest are inherited from the mother?
Identigene says
Hi, Kate. A child inherits 50% of their DNA from mom and 50% from dad, so there is a maternal and paternal match at each and every locus.
Anne says
my husband and his brother had a Y chromosome test done and it came back with 7 out of 22 matched. He was told that they do not have the same father is there a chance that his fathers brother could be his biological father.
Identigene says
Hi, Anne. If your husband’s father and his father’s brother have the same biological father, then they would have the same Y chromosome and the result would be the same, so most likely no. From what you said, it sounds like your husband and his brother have different biological fathers and are half-siblings.
Hopeful says
I had my daughter 24 years ago. When I was pregnant with her, I told the man who I thought was the father that I’d been with someone else close to the alleged conception date. We’d split up briefly and I’d gone and seen my ex during that time. But the “father” I thought was hers after all these years, the man I was truly convinced was her dad, the man I married, has now taken the Ancestry Dna test and so has my daughter. She is not showing up as a match. He isn’t showing on hers. She doesn’t know anything yet. We told her his was just taking a long time for results. Is there ANY way that could happen if he was her bio father? Could there still be a possibility he is her dad? Should we not trust that and do a true paternity test? This is ruining our lives.
Identigene says
Hi, Hopeful. Yes…do an actual paternity test to be sure.
Hopeful says
Hi again. Thank you for the response. Would that be a “yes” to all three questions?
Identigene says
Yes to all three questions.
kimmie says
two brothers and only one would take the test. the test came back and 17 out of 20 numbers matched. does this mean hes my childs uncle? with that many matching number is it a strong possibility its the brothers?
Identigene says
Hi, Kimmie. The calculation for relationship is more complicated than simply “matching numbers,” especially when it comes to determining who is the father when the two alleged fathers are brother. Did you let the lab know ahead of time of the other possible father who would not test? I would contact them and ask some questions.
Mashila says
What is the difference between taking a blood sample ( pin prick) as opposed to taking a mouth swab? Which is more reliable? Even if it was witnessed by a legal party, for child support cases.
Identigene says
Hi, Mashila. DNA is the same, regardless of how it is collected. Most labs now use cheek swabs because the robots used for DNA extraction are made for them, and also because it’s painless and easy for the customer and doesn’t require a medical professional’s help. You can learn more about it here: https://dnatesting.com/using-buccal-swabs-vs-blood-samples/
Candace says
Hi there! Just had a test done and the results state the alleged father has 0% chance to be the biological father. I’ve never been with anyone else. How can this be!? Can the test be wrong? Thanks
Identigene says
Hi, Candace. You didn’t mention whether or not you tested with us, but be assured that if you used an accredited lab like ours, then the results are accurate for the samples the lab was given. The lab has no way of verifying whether or not the sample submitted for the alleged father is actually his or if he may have swabbed his buddy and sent that sample in as his own. For an at-home test, the burden is on the customer to ensure they witness all swabbing as well as the mailing of the samples. If you suspect the man tested may have committed some kind of fraud, you may want to consider doing a legal paternity test where DNA collection is witnessed, IDs are checked, etc. If you’d like to go that route, you’re welcome to call us at 800-344-9583.
sky54128 says
Took a non invasive prenatal paternity test with DDC in 2015. Results came bake with probability of paternity > 99,9 %. I still doubt. Why there are not more 9s behind the comma? Shoud I trust?
Identigene says
Hi, Sky. Whether the probability of paternity is 99.99 or 99.99999, it really doesn’t make a difference. They are all conclusive results. A calculation is made to determine that percentage, and the number of 9’s after the decimal depends on the individual strength of the data at each marker. No worries!
sky54128 says
Thx for your Answer!
Identigene says
You’re welcome!
Sara says
Can a person look like someone but not be there child just because they look like the person doesn’t that mean that’s their child right asking for a friend she’s kind of confused about who she’s been with but she says the one that looks like her daughter is not the father but the other man doesn’t look like her daughter and she says he is the father so what does she do
Identigene says
Hi, Sara. Physical appearance is never an absolute determinant of paternity. Only DNA can establish that. There are many children who share a biological relationship with their parents but don’t look like one of them or both of them. Some look like little carbon copies of a parent. It really just depends on the genetic lottery and what the child happens to exhibit.
Jayden says
i got dna test results today from the mother, it says probability is 50%. they test 26 markers and quiet a few do not match. i was tested, child and mother.
there is a comment at the bottom which says, the biological faither is Either the alledged father or number 2 somebody who is entirely unrelated.
it goes not to say
before considering the dna evidence probability is 50% either way.
i can send you the results
Identigene says
Hi, Jayden. I’m assuming you are the alleged father? It sounds as if you should have chosen a different lab to do your testing. With you, the mother, and the child testing, there’s no excuse for returning a 50% probability of paternity.
Julia says
Hello,
18 years ago my husband was told he was the father of his ex’s child. She was known to get around and was even sleeping with his cousin. They ended up getting 3 DNA tests. One was positive, one was negative, and one was inconclusive. I would never believe this story if I hadn’t seen the reports myself. My question is how is this possible? And they were all done by the same lab which was testing for child support purposes.
Identigene says
Hi, Julia. To clarify, are you saying they did three DNA tests with the same exact participants for each test?
Angelic says
What if the father dna and son dna are on the same swab ?
Identigene says
Hi, Angelic. The lab will see that there are two DNA profiles on one swab and ask for a new sample.
Joy says
I have 6 out of 7 paternal markers that match from an accredited DNA lab. This makes the alleged father exempt from being my paternal father. I also sent a sample to ancestry (at the same time – I sent the dna sample). Ancestry’s result placed me directly related to my “exempted father’s” family line. It shows that his parent’s relatives are my relatives. Since it became quite a mystery, my daughter sent her sample to ancestry too. She purposefully sent it without making any connections to me. She came up directly under my line as my daughter and under the same family line as well. The only conclusion I have been able to come up with is that I’m in that family line and perhaps my uncle is my biological donator rather than the man I knew as my father, the man who raised me. My mother was quite permisques back in the day…so maybe? What are your thoughts?
Identigene says
Without seeing your data, I can only make an educated guess, Joy. Your biological father may very well be someone closely related to your exempted father.
Joy says
Thank you – it’s the only conclusion I can come up with
Joy says
Not sure the first part of my message was clear. I meant to say out of 15 markers 6 were not a match but 7 were a match, making the alleged father exempt.
Oliver says
Hi my name is Oliver, my sister and her ex did a home dna test for their 2year old daughter, but i believe they switched the swab of the father with the swab from my sisters son (different fathers) will the results come back positive? Being as though they share the same mom and are in fact related?
HomeDNA Identigene says
Hi, Oliver. For paternity testing, the sex chromosome is included, so the lab would have caught that a sample that is supposed to be for a female child actually belongs to a male. Testing would have been suspended and the lab would have asked questions. So, no!
Catherine says
I went to a facility that the alleged father located. I believe there to be fraudulent activity on his and the lab ladys behalf. How would ingonabiut proving these claims?
Mark says
Hi if the lab tested 19 locations and the mother has XX chromosomes and the fathers have XY. And the baby is a boy has XY doesn’t that mean that the mother has double the chance of giving the baby an X chromosome since 38 possible from the mother and 19 possible from the father. If you do the math isn’t the mother got a higher chance since 2>1 and 38>19. Since the baby is a boy then the mother can’t give the baby any Y chromosomes. If you have 19 markers being tested then doesn’t the father only need 9 or 10 matches out of 19 since if you do the math you see that 12X is not equal to 12Y on the chart. So it looks like that you don’t know how to read your own DNA test results cause the mother may match at all 19 locations but the Father has less chances of providing an X, the mother has a 2 times better chance so by the results looking like the father provided about 47% or 53% the real results taking into consideration that the 2 is greater then 1 rule like 38 is greater then 19 rule so it would conclude that the father would only need 9 out of 19 matches to be the Father. If you put a 0% probability of the father being the father with this many matches and you have ruled out that the alleged Father was actually the Father with 100% cause all he needed was 1/2 chromosomes to come from him but you say all the markers have to match but that’s not how the math works or how u get 1/2 from mother and half from Father. How do u justify that a mother can’t give the baby y chromosomes?
Suresh says
Hi IdentiGene ,
There are two Possible fathers involved for Paternity.
Me (Alleged Father 1),My Wife and my child had been tested for 24 Markers Paternity Test. All of my child Markers are inherited from Mother and AF 1.
Test results are The alleged father can not be excluded as being the biological father of the child with Probability of Paternity is >99.99999999% and Combined Paternity Index 38,164,564,715.
There was 2nd test done with Alleged Father 2,Mother and Child had been tested for Paternity test. 15 Markers were not matching out of 24 Markers .
Test results are The alleged father is excluded as being the biological father of the child with Probability of Paternity is 0% and Combined Paternity Index 0.
My Question here is who is the Father of the Child? Whether Alleged Father 1 or Alleged Father 2?
I am the alleged Father 1. Do I need to do some other tests to prove my Paternity. Please help me.
HomeDNA Identigene says
Alleged Father 1 is considered the biological father.
Paige says
Hi,
I just received test results back for 2 children for the same alleged father.
The first one came back positive 20/20 markers matched with 99.9998%.
Second test: 12/20 markers matched. With 0%. 12 matched, 8 didn’t.
Is this correct, the mother think the test may be wrong because the baby is only 4months and was slobbing alot, and this may have affected the test.
Also, the mother wasn’t tested just the kids and the alleged father. I’m looking at both results, being the kids are siblings shouldn’t one or the other allele number match between to the two kids? I’m asking because on 3 lines the kids Allele doesn’t have a match for an allele between the two kids
HomeDNA Identigene says
Hi, Paige. A test result cannot be “wrong” because the baby was slobbing a lot. Slobbing wouldn’t change DNA, but it could contaminate the swab. Since results were issued, this wasn’t a problem. Half siblings share 25% of their DNA only; including the mother’s DNA would not make a difference for an exclusion.
Paige says
I’m going to ask again, because I’m not sure if I gave enough information.
Hi,

Second test: 12/20 markers matched. With 0%. 12 matched, 8 didn’t.
Is this correct, I think the test may be wrong because the baby is only 4 months and was slobbing alot, and this may have affected the test, because he is the father of both, and I’m the mother.
Also, the I(mother) wasn’t tested just the kids and the alleged father. I’m looking at both results, being the kids are siblings shouldn’t one or the other allele number match between to the two kids? I’m asking because on 3 lines the kids Allele doesn’t have a match for an allele between the two kids for a mother match. Also, some numbers are missing, and I read that usually mean the same number so I assumed that, when I do that and match things against my daughter and son they don’t match ( the other allele should be for me, being my daughter matched the father at 99%, the other allele on the 20 lines for my son should match one of those numbers from my daughter report if I’m interpreting correctly? Trying to make sure dad didn’t swab a random boy for the test.
HomeDNA Identigene says
Hi, Paige. You should not expect a match at every locus for the children. Even if they were siblings, they only share 50% of the same DNA. Numbers are not “missing” on the report. If, for example, it shows just one “11” at a particular locus, that means that the two alleles there are the same (or 11,11). “Slobbing” doesn’t affect the test and you can be sure the results are correct for the samples we were provided. Since this is a home test, the burden is on the customer so ensure that samples for the correct people are submitted. If you didn’t supervise everyone’s collection you have no way of knowing whether or not “dad” submitted someone else’s DNA. If you still have doubts, you may want to test again, but do a court-admissible test with witnessed DNA collection to prevent fraud. I will say this: If the exact same DNA is submitted for the legal test that was submitted for the home test, you can expect to see the exact same results again.
kathleen says
my dna came back without my father being the sperm donor… is it possible to check with close cousins or family in my dna groups to figure out who he may be? Would I be looking at 1st cousins or something else..just trying to narrow it down. Both parents have passed so I am in limbo.
HomeDNA Identigene says
Hi, Kathleen. The best way to do that is probably through an ancestry DNA service that shows possible family members.
Ruby says
Help a confused mother, she had sex last week in February and ending of first week in match she had sex with another man, 7 days after the first man. Ending of match she noticed she was pregnant and keeps the baby, DNA was carried out this year with the first man and he has 0% match with the boy not even one match, how true is this that the man will not have single match even if he’s not the father. Mind you he went ahead of the mother to do his own test both party are not there when test was carried out
HomeDNA Identigene says
Hi, Ruby. Without seeing the report myself I cannot comment on specifics. It is possible, of course, to not have a single match but it is out of the ordinary.
Ruby says
Please how can I contact u with the paternity result

Our number is 800-344-9583.
Deonbrel says
Hello, my son was tested with a home test about a year ago. I do not believe that everything was properly done. I was there to witness, but some things stroked me as odd & the alleged father’s family performed the test. The results are confusing as well, yet the alleged father was considered not the father of my son. They have many similar markers. Can you review the results for me & discuss this matter?
HomeDNA Identigene says
Hi, Deonbrel. You shouldn’t post it publicly, but you’re welcome to contact us privately via Messenger on our Facebook page: https://www.facebook.com/HomeDNAIdentigene/
Scott says
I believe my identical twin brother isnt the father of his alledged child. He doenst want to do the test but his ex girlfriend, mother of the child is willing to participate. Me being identical twin, can I submit my DNA and it will show if my brother is the biological father? And can the test be less than 99.9%
HomeDNA Identigene says
Hi, Scott. Technically, because you are identical twins, you could in theory submit your DNA. A good lab would always return results of 99.9% or higher for an inclusion or 0% for an exclusion.
Steven M says
We all took the test. The mother lied on the test and reported that she was of a different race. She’s Mexican and reported Asian. I’m Mexican.
The results shows a 99% probability of a match.
Is lying about ones race influence the accuracy of the test? Could this not be my child?
HomeDNA Identigene says
Hi, Steven. It could affect the probability percentage, but not the final conclusion.
phumelele says
hi all i tested with the alleged father the result came negative all 13 of the makers they match with him only 3 didnt match different is only 1 number apart
and his the only guy i slept with
please assist
HomeDNA Identigene says
Hi, Phumelele. The allele length being only one number apart doesn’t matter. What matters is that there were three genetic markers without a match. With the exception of a mutation, a child’s data must match the alleged father’s at every single location. As for his matching your child at 13 markers, that’s not unusual at all even though they’re not biologically-related. As humans, we share quite a bit of the same DNA. You and I probably match at a lot of locations too. The key for paternity is to have those matches at every location.
Nancy says
Hi I had a question,
My husband did a dna test with mother and child. The results came back 0% on both of paternity index and probability. But my question is that 7 of the markers texted were a match, the mother of child is now claiming his brother is the father is there any way to tell from his brother (my husband) results that their is a possibility? They are half brothers same mother different fathers
HomeDNA Identigene says
Hi, Nancy. It is not unusual at all for a possible father and a child to match at many markers even if they’re not related. You and I probably match at several markers just by virtue of the fact that we’re human and share 99.9% of the same DNA. The fact that there were matches doesn’t mean anything in terms of whether or not his half-brother might be the father.
Miranda says
On a recent DNA test that was done. They are saying the alleged father is excluded but there is a 99% chance he is the biological father. However the mother and the father share some of the same numbers on the loci. So is there a chance there could be a different biological father
HomeDNA Identigene says
Hi, Miranda. Something’s not right with what you’ve described. If a man were excluded on a test, then there would be a 0% probability he is the biological father, not 99%.
Smith says
Hi my partner has two kids, he has had a dna as his brother was to ment of slept with his kids mother also, so he done a dna he stated on one child’s records his brother cud also be the father and her likelyhood ratio was 12.08 million but the other child he forgot to put down his brother could also be the father and her ratio is only 1.02 Milloon witch is a big differcent so say he did put down the 2nd child could also be his brother witch this indicate what the likelihood ratio is so low??
HomeDNA Identigene says
That could be why, but it most likely is just an indication of the strength of the matches. 1.02 million is still a very strong combined paternity index. He may want to retest nevertheless. It is ALWAYS important to let the lab know ahead of time if the other possible father is a close relation.
Janet says
My daughter had a paternity test done and the results turned out negative. The ex boyfriend was tested and also negative and the boyfriend after was also negative. These were tested with all three participants present. She is adamant that the older guy is the father. He went for the blood to be drawn at another pathologist office in another town. She was with this older man (24 years her senior) in October 2009. On the 18 November 2009 was already 6 weeks 4 days pregnant according to first scan.
After 9 years of support he demanded a paternity test and this came back negative. He is now 58 years old. She is determined that he is the father. He went for the blood to be drawn at another pathologist office in another town. Can his age have anything to do with it. She has requested that they go for another test where all parties are present. He does not wish to have anything to do with the child that is why he arranged to go to another place for the test. To date has not answered about another test. Can anyone give any light or advice please. We have read some articles about gene mutation but have no knowledge or understanding about this.
We honestly don’t know what to make of this and the child suffers cos she wishes to know who her father is.
HomeDNA Identigene says
Hi, Janet. Age of the alleged father does not affect a paternity test whatsoever. Any genetic mutations that may exist are taken into account by analysts as they prepare their report.
K Y says
Hello read an article how marijuana can change your genetic profile in sperm, so my question is if it was possible that heavy marijuana use can influence a paternity test?
HomeDNA Identigene says
No, it doesn’t affect a paternity test in any way.
Jay says
Hi, I their are two sisters who claim to be my fathers kids. They had a DNA test done with my father’s aunt because he is deceased. The test I had done when my Dad was alive came back 99.99% the test they did with my aunt came back 99.95%. The test also states “a brother could be the biological father” but I’ve heard it had to be 99.97% or higher? Is this true? I’m trying to prevent paternity fraud if so.
HomeDNA Identigene says
Hi, Jay. When a test for paternity is performed indirectly, such as an aunt/uncle (avuncular) test, the threshold for probability of paternity is lower than for a straight paternity test. 99.5% is actually quite a high probability of relationship for an avuncular test. As for the statement that a brother could be the biological father, it might be advisable to start asking questions within your family and perform additional testing if that’s possible. But from what you say, it certainly appears that you have half-sisters or cousins.
Jay says
And if we were tested with our Moms, would it show a 99.99%? One alleged half sibling is 5million to 1 on the “sibling index” and another one is “91,00 to 1” on sibling index. But both show 99.99%. How is that?
HomeDNA Identigene says
Including moms can definitely strengthen results. The “combined relationship index” is a reflection of how common or uncommon a specific set of genetic datapoints is for the locus tested. For example, if the vWA locus is 17/20, the analyst does calculations for how common that dataset is for a Hispanic male and assign it a relationship index of 14.84, because it’s rare. For a Caucasian male, it might be more common, so it’s given a 0.93 relationship index. All the relationship-index numbers are multiplied together to get the combined relationship index ratio (in one sib’s case it was 5 million to 1 and for the other it was 91,000 to 1).
The CPIs are different because the two siblings’ DNA have differences…they’re not exactly the same. The sib with the 5 million to 1 CPI had more uncommon datasets than the other sib’s, which is why the CPI is so much higher. The probabilities of paternity can be the same, even if the CPIs are different.
It’s really, really hard to explain this part of the science in layman’s terms (and in writing!), but I hope it was helpful.
Christine says
Hi.
I did a prenatal paternity test at DDC. I watched the man, Who I do not think is the father, take the test at the midwifes Office . while taking the blood test myself. Unfortunately, there was not enough DNA from the fetus in my sample so they needed a new. It was sent, and short after we got the result. he is excluded as the father. the letter says:
“Paternity determination was performed using 1661 SNP (Single Nucleotide Polymorphism) informative loci out of 2,304 tested loci to generate a probability of paternity”
What does that mean? Is this a lot? How accurate is this test? I
HomeDNA Identigene says
Hi, Christine. DNA Diagnostics Center (DDC) is our parent company and we absolutely stand behind the accuracy of the test. What that statement means is that there are a total of 2,304 genetic markers that can be used to determine probability of paternity for a prenatal test. The analysts were able to establish a probability of paternity using 1,661.
Jaide says
Hello so my daughter was tested through DSS and for my results but says that he is 0% the father but there are some markers that match and the picture I seen didn’t look like my kids alleged father but he has a half brother or cousin that his friends and family say went for him because he didn’t want to pay child support but the girl he has a son with sent me screen shots that he wants to do another DNA test but DSS didn’t ask him to retake the DNA test they just gone compare it to the last one he used but there are about 8 markers that match his and was wondering if the report can be read to prove that my daughter has some relation to who took the test like if it was his cousin or half brother is there way to see results to see cause if it’s his half brother and they have the same dad i don’t know just don’t know how to read it ?
HomeDNA Identigene says
Hi, Jaide.
As human beings, we can expect many of our same markers to match, whether we’re biologically-related or not. The key with paternity testing is that ALL markers tested must match between a man and child for him to be considered the biological father. They might not match at one genetic marker due to a natural mutation, but analysts take that into account when generating results. It’s pretty difficult to commit identity fraud when doing a legal paternity test where everything is witnessed. Your best recourse is to contact a family-law attorney to see if you have any other options. Good luck!
Brittany says
I did a sibling test with my two kids & the alleged fathers daughter. My son came back 99% with a combined index of 90k. My daughter came back 99% with a combined index of only 27k. I was under the impression that daughters shared more dna with their fathers and was shocked that my son and their half sister shared more dna. How do you get a 99% from a combined index of only 27K. Should I be concerned that my daughter has a different dad?
HomeDNA Identigene says
Hi, Brittany. The 99% refers to the probability of relationship between the siblings only. That is the question that was asked and answered for the test and it is unrelated your daughter’s data if she were compared to her biological father.
Brittany says
So if they are 90% positive the siblings are related that indicates they share the same father for sure?
HomeDNA Identigene says
If the result for a sibling test shows a 90% probability of relationship, then yes, that is considered conclusive.
Sarah says
Out of the 15 marker main loci if 3 didn’t match but 12 markers did does that mean he is the father or not I’m a bit confused cause 12 markers is a lot to share with a person and not be related
HomeDNA Identigene says
Hi, Sarah. As humans, we share 99.9% of the same DNA. So having so many loci match is not uncommon at all. In fact, you and I would match at quite a few of these also, no doubt. What we look for in a paternity test is whether all of them are a match. Since a child gets 50% from bio mom and 50% from bio dad, it makes sense. Sometimes there may be one or even two mismatches between a biological father and child, due to genetic mutations. This possibility is taken into account when performing the analysis. It sounds like, in your case, it was an exclusion (meaning he’s not the father), since there were three mismatches.
robyn lee says
I had a DNA test done all out two boxes matched and they said he’s not the father should I have the test redone
HomeDNA Identigene says
Hi, Robyn. Unless there’s a genetic mutation, all genetic locations need to have a match for the man tested to be considered the biological father of the child tested. If only two matched, that’s not enough, and it’s an exclusion.
Sam says
A paternity test is about to be carried out on Mr. A (Father) and 1-6 (Children)
Their mother had an affair with Mr. A grown up son (Mr. B her step-son) for many years
If she had a Child or 2 for Mr. B during that time,
And the test is down between Mr. A and the 1-6 Children
Will the result be 99.998% for the child/children that belong to Mr. B?
Should we inform the lab that the mother had an affair with Mr. B her step-son?
or will DNA single out the child/children belonging to Mr. B
Please i need a detailed Responds.
Thanks
HomeDNA Identigene says
Hi, Sam. You definitely need to tell the lab ahead of time of the possibility that the step-son of the man being tested may be the father of one or more of the children. That way, the lab can take this information into account when doing its analysis and test additional genetic markers too, if necessary.
Bethany says
I had a DNA test done on my son about a month ago and his (alleged father) had his dna test done several weeks later, both test were done through the child support office but my sons test was takin in Tennessee & his (alleged father’s) was done in Ohio. The test result came back through the mail with a 0.00% chance. But I do not believe the test results are correct, I am about 99% positive that this man is my sons father & I want the test done again. We have court for child support coming up next week. Is there a chance that the lab got the test results wrong? I seriously believe that this man is my sons father and I want to have the test done again with both my son and his ( alleged father) in the same state this time. Is there a possibility that the test was wrong and the court will let them retake the test with both in the same state at the same time? I just need to have the test redone one more time for piece of mind I guess.

Hi, Bethany. Whether or not you do another paternity test for your own peace of mind is up to you. It doesn’t matter where DNA was collected for your test…whether it was in separate places or the same place. The samples were reunited at one lab, which performed the testing. Since this was a court-ordered test and not a home test, you can be assured that the DNA submitted for testing was for the participants who were supposed to be tested: your son and the possible father and you can trust that the results are correct. Sometimes, especially in cases of child support, results aren’t what some people expect or hope for, but DNA relationship testing is legitimate science, which is why the courts trust it.

Hi, had testing done 19 yrs ago… They matched up in 10 out of 12 different fields. So he was not the father. Don’t have results anymore and can’t locate them, however it was 98.4% something like that , and .06% of population could be father not sure the exact lingo used but that’s the exact gist of it. However I was told later that it could have been a mutation being that 98% is almost 99% and yes she has his teeth lips eye shape and deep dimples but she is lighter than both of us. What do these results sound like to you. It was not 0% or 99% but they did say he was not the father… They matched all but 2 fields in the test and yes I tested as well.

Hi, Gladys. Without the exact data, it’s hard to comment. The technology is so much improved now…can they not test again?

Hi, I haven’t used Identigene, but I’m looking into more information. I recently had 2 different men tested. (Before any judgement is passed) I’m not a saint I had a bad breakup and mad a bad decision. I’ve slept with my ExBF March 27 and had a one nightstand March 31. When I found out I was pregnant the doctor gave me a conception date of March 31. However, I recently had the Other man tested which came inconclusive. Although, I should add this lab messed up our test 3 times. I was informed AFTER the results that our results may have been contaminated and we needed to retest! I test my Ex as well and his came back inconclusive. Now BOTH men had matching indications to my child. And the baby looks like both men! Is there any product we can do to have all 4 of us tested. I haven’t did the retest with the other man yet. I’m not too sure on that labs credibility. I was informed they are under staffed and mainly focusing on COVID-19 testing! We just want this charade over with and neither alleged fathers trust the lab we recently used. Which is a shame because they’re a certified accredited well known lab.

We were also informed of 4 maternal mutations. I’m not even sure what that means.

Hi, we’ve recently did a retest using a different lab and it showed the ‘one night stand’ is my child’s father. I also, want to note: we did Legal Paternity testing BOTH times and their facilities. We watched each other samples be collected and sealed. I do not have a Facebook at this time. Yet, we are all four doing another test with your company (Identigene) because we are all on edge. We just want to make triple sure these results come back the same.

I have a question about if the alleged father of a child is barely spending time with him or paying child support. Should he not be able to see the child till he pays or what? Because my boyfriend is giving me money when he can. He is also being more of a father to my son then the other one is. My son even calls my boyfriend dada so i don’t know what to do about the whole thing. And the one that my son calls daddy came into his life in September of last year. But before that his alleged father waited till he was 4 1/2 moths old for a test to be done.

Hi, Emily. This is a question best answered by a family-law attorney or social worker where you live.
