We sometimes receive inquiries from customers questioning if it’s possible for one participant in a paternity test to switch samples, either with themselves or someone else, or if they could have changed the DNA somehow by eating before collecting DNA. If this happens to you, it is considered paternity fraud, and you may not get the accurate results you are looking for. Here are some sample scenarios.
Paternity Fraud: Mom submits her DNA as the alleged father’s
One question we encountered recently was a concerned possible father who thought maybe the mother of the child could have swabbed herself in his place to force the results to show not excluded, meaning he is considered to be the biological father.
In all paternity testing cases our laboratory also includes the amelogenin gene to verify the sex of all participants. This helps to verify the alleged father being tested is male and the mother is female. We can also verify the sex of the child. This means mom could not swab herself and submit her sample as the alleged father without our laboratory experts discovering that. If this does occur we place the paternity test on hold and contact the participants to ask them to re-swab the correct participants.
Another sign that the mother swabbed in the alleged father’s place would be the mother and father would show as identical DNA, which is not possible. This would also be a red flag and cause the paternity testing to come to a stop. When testing is suspended, participants are contacted and asked for new samples.
Paternity Fraud: Switching samples with someone else
Another question we sometimes get asked is whether the alleged father could have switched his own samples with someone else. If you purchase the home DNA collection kit for paternity testing purposes, the results you receive are not court admissible. This is because the laboratory cannot verify whose samples they have actually received. If the participants do not collect the samples together and mail them off together, there is always a risk that someone could switch their samples with someone else.
If you are in a situation where you doubt the reliability of the other person to be honest about submitting their own sample, we always recommend a legal paternity test collection. To prevent any doubt of someone committing paternity fraud, all participants should go to a third-party collection facility to have their DNA collected by an approved witness. This collector verifies ID and take photos of each participant. The collector then sends the samples to the lab for testing to establish a chain-of-custody to verify samples could not have been tampered with.
Paternity Fraud: Eating or drinking before DNA collection
Another question we get is whether someone can alter their DNA by eating or drinking something before they swab their mouth. The answer is no. You cannot alter your DNA by putting anything in your mouth. If you have had a bone marrow transplant recently, that affect results. Anything like that should be discussed with the facility doing the paternity testing.
We do ask that you don’t eat or drink anything for about an hour before collecting the DNA samples, to keep food or anything else off the swabs. Eating or drinking before the collection can cause remnants to get on the swab with the DNA. The worst this will do is create a situation where we can’t get a profile at all. If a profile is obtained, then the food or drink did nothing. If we can’t get a profile, we ask for a recollection at no charge.

The Bottom Line
When doing an at-home paternity test for peace-of-mind purposes, we highly recommend that all participants watch each other collect DNA samples, put them in envelopes, and then go together to the post office to drop them off. If that’s not possible or if you suspect that one of the participants may want to commit a fraudulent act, then do the wise thing: Pay a little extra for a legal paternity test from our parent company, DNA Diagnostics Center (DDC) and have the whole process supervised by an approved witness. Results are court-admissible too!

Hope says
The alleged father has done a DNA test with another child at another facility. Can I submit my swab and my child’s swab with the results of his test and compare it?
Meisha says
Good afternoon Hope,
We do offer an individual DNA profile test. This would show the single participants alleles that you could compare with the results from the first test.
However, to get the strongest and best result we would highly recommend doing a paternity test with the alleged father, child in question, and the biological mother of the child.
Please contact us at 888-404-4363 at your earliest convenience so that we can assist you with your testing needs.
Rochelle Youngblood says
I have an question if two different girls get the same dude tested but on both of there dna result his dna pattern shows up different how is that possible would that be an lab error being that dna don’t change since its the same dude?
Admin says
Hi, Rochelle. If everything’s on the up and up and testing was done at accredited labs, the profiles would be EXACTLY the same. Since most of the testing is performed by robots, the chances of lab error are extremely small. It’s much more likely that the man submitted someone else’s DNA as his own for one (or even both) tests.
Rochelle Youngblood says
Hey again. I know an home dna is for the mom baby and father but do you think if we used both of the girls to see if their sisters would it work. I just dont want to go thru the father again and he might pull the same thing again?
Admin says
I’d wait on buying the kit. We can’t test just sisters and their mother to see if they’re related. We need someone on the father’s side of the family. Contact us directly at 888-404-4363 and one of our experts can walk you through what’s needed.
Cassie says
Hello my name’s Cassie and I have a CPS case open With my 6th month old daughter and they ordered a paternity test. The man who I thought was the father went down n took the test they set up… Results came back saying he isn’t the father… Is there any chance he could of forged the test or results??
HomeDNA Identigene says
Hi, Cassie. If it was court-ordered test, there’s no way for him to forge the test or monkey with results.
Demi says
Hi, I’m demi and I’ve recently had a DNA test result done regarding my partner and my son. The results came back positive that the man who I thought to be my sons baby actually is. But I didn’t get tested as the mother can this be a negative if I redone the test? As I am hoping he is the biological farther thank you kindly
Identigene says
Hi, Demi. Your participating in the test would not have changed the outcome in this case, no.
Kimberly says
I need. one done on my baby daddy drae. bivens. and Terrance Washington
IDENTIGENE says
Hi, Kimberly! Give us a call at 888-404-4363 and we’ll be happy to help you test with us.
Jade says
Hello, I did a test about 3 years ago om my daughter and potential father. Im so convinved he got one of his parents to do the test for hom as he was certain he didnt want anything to do with her. Is this possible and would u be able to tell? Also if this did accure would u be able to tell that the person was related to my daughter just not her father? Hope that makes sense. Thankyou.
IDENTIGENE says
Hi, Jade. The short answer is yes, the lab can pick up on if it’s a close relative such as a grandparent. Oftentimes if the lab suspects that the person being tested is a relative (just not the biological father), they will have customer service contact the client or they will make a note of it on the paternity report.
Mikoyia says
Can DNA also tell age
Admin says
No, paternity testing does not tell age.
Wilbert says
Hi my kids mother had me take a DNA test. 1year later I looked at the results again and again, the name says Labcore. So I googled the name and what I got back was that their documents are fake and fraud. Please tell me how do I get to the bottom of this?
Admin says
Hi, Wilbert. You probably want to contact a family-law attorney to see what can be done.
Etirous Thompson says
I am 100 per cent sure my son is his son tests came back said no
Is there some way he sent someone else in his place undetected?
Admin says
Hi! Was it a legal test that was witnessed? If so, IDs are checked to ensure the right person is being tested. If he collected DNA at home with no one else to witness, he could have sent in someone else’s sample instead of his own.
Amber says
I had a test done three years ago but lost results how long are the results kept can I get a copy still?
Admin says
Hi, Amber. Give our Client Support Team a direct call at 888-404-4363 and they’ll be happy to help you.
Tanya says
Why do the DNA results come out negative when I know he is the dad and I have done 3 DNA one came out positive and the other 2 negative?
Identigene says
Hi, Tanya. Were any of these paternity tests “legal” tests? Meaning the DNA collection and sample-mailing was witnessed by an approved and impartial DNA Collector? Because unless all participants supervise each other during testing and mailing, there’s a chance that some fraud could occur. For example, the alleged dad could send someone else’s DNA in to the lab instead of his own. If that’s the case, of course the results will be negative.
Cameron says
I am pretty sure that I am not the father But the results came back positive I was wondering if the mother swabs the baby’s mouth twice on different sides and we are the same sex if there is also could come back positive
HomeDNA Identigene says
Hi, Cameron. No, that’s not possible. If she had done that, the DNA profiles for child and the father would have shown as being exactly the same (since they were for the same person).
David says
Hello just wondering after doing paternity test and sent them to the lab . Can the lab take bribes from the other alleged father ? to lie on test results ? Random question and it’s about all the labs in the uk ?
HomeDNA Identigene says
No.
shamega says
Me an the father of my child did a home DNA test an I thank him an his girlfriend changed some thing because she don’t like me an another reason I say this is because I didn’t get any thing bye mail are by phone telling me he wasn’t the father
Meisha says
Good afternoon Shamega,
We only mail based on request, and we do not call out for results for privacy and security purposes.
We would be more than happy to assist you with your case, and getting you the results. This would be easiest to address by calling us at 888-404-4363 and talking to a DNA consultant over the phone. We look forward to hearing from you.
Tony says
Is it possible for the alleged father to have instead of stabbing his own cheek swabbing the child’s cheek twice for a false positive result and if so would you be able to tell if that happened reason for asking I believe my.girlfriends ex has done this and do not believe he is the father ( and I am not )
Meisha says
Hello Tony,
When our lab does the testing on the samples received for your case we do make sure that we are testing two participants DNA. If the same persons DNA was on both the child’s samples and the alleged father we would not be able to complete the testing. In the case the same persons DNA comes in for both participants we would have to place your case on hold and ask for a recollection, it is not possible to produce results with the same persons DNA for both alleged father and child.
I hope this information helps. If you have any further questions or concerns please feel free to call us at 888-404-4363 and a DNA consultant will be happy to assist you!
george says
Is it possible for you to tell if the mothers dna was used in place of the alleged fathers for a positive result ?
Meisha says
Good afternoon George,
Yes, our lab would be able to tell if the mothers DNA was sent in under the alleged father. This is because we check gender on all DNA samples sent in to us for testing. Since an alleged father cannot be female, we would ask for a recollection from the correct participant. It would not be possible to produce results (no matter the outcome) with an alleged fathers samples being from a female participant (whether it is the mother of the child, the alleged fathers sister, etc.).
I hope this information helps. If you have any further questions or concerns, please give us a call at 888-404-4363.
Nally says
Is it possible that the mothers DNA was tested as the daughter DNA? A mix up in the envelopes! I believe an error was made!! I’m gonna get to the bottom of this
Meisha says
Good afternoon Nally,
As a mother and daughter are both female we have no way of identifying who’s is who’s other than going off the information sent in to us to test with. If there was a sample switch then there would be a possibility of our lab catching it, but that is not for certain since again, both participants are female. If the lab was not made aware of a possible sample switch before the testing was done, and the results were released, then the results are 100% accurate based on what was sent to us to test with (including mixed up samples). Our recommendation would be to either; do another personal paternity test with all participants present to witness all the samples being collected, placed in the specimen envelopes, and being dropped at the mailing facility, or; we do offer a legal DNA test where all participants must be collected by a disinterested third party collector. This process prevents anyone from being able to provide incorrect samples, and to avoid any sample mix ups.
I hope this information helps. If you have any further questions or concerns, please contact us at 888-404-4363. Thank you.
Jhon says
I have a question, is it possible to have one number different on my dna profile, than my biologicals parents on any system. I explain my question. Say my dad has 13,12 and my mom has 13,15 on the system Penta D. Can i have 13,18 on the same system. Is it possible that i have number they dont have in that system?
Identigene says
Hi, Jhon. Yes, it could just be that you have a mutation at that locus. If you were to do a paternity test, that possibility would be taken into account when calculating probability of relationship.
Tiffany says
My friend has a son and there’s this guy taking her to court for paternity but he believes she has a daughter there was a court order for her that guy and the baby to go to the lab for testing but the baby is a boy not a girl and on the court order it has a girls name what would happen in this case when they go to the lab
Meisha says
Hello Tiffany,
Unfortunately this is not a question we can answer as we are not able to provide legal advice. We would recommend that your friend contacts the court house to explain the situation and see what they have to say. Paternity tests are tested, and results released, based on the samples and information provided to the lab. It is up to the judge if they would accept the results for a male child when their information states the child is female. Your friend can also consult with an attorney for further information about the case.
If you have any further questions or concerns, please feel free to contact us at 888-404-4363. Thank you.
Tom says
If a test is done by two different fathers will the babies results be identical on the two different test done by two different men
Meisha says
Good afternoon Tom,
If a child participates in a DNA paternity test with two alleged fathers, it is not possible for the results to be identical unless the alleged fathers are identical twins, as they would have the same DNA. If the alleged fathers are not identical twins then the results could not be the same. Based on the DNA profiles between the alleged father and child, the results will either come back as we do consider a relationship (“is not excluded” with a probability of paternity of 99%-99.99%) or there would be no paternal relationship (“is excluded” with a probability of paternity of 0%).
I hope this information helps. If you would like further assistance on understanding the paternity test results please feel free to contact us at 888-404-4363. Thank you.
sergio says
how accurate are over the counter paternity tests? i found out my daughter is not mine biologically. her mother took a test with the alleged biological father that was bought from a drug store and it came back 99.99% that he was the father. i am skeptical of this and want to know what the margin for era is and is there any possibliltlity that the test could be wrong?
Meisha says
Good afternoon Sergio,
We provide the most accurate testing available on the market today. The results we provide are 100% accurate based on the samples and information sent to us to test with. We follow very strict guidelines in the lab, and are accredited with several different organizations (see below). Any test completed with us will produce the same results as another company, as long as exact same participants are testing.
If the test was done with a different company, we would recommend contacting that company directly to speak with them about their processes.
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.

Janet says
A girl from my brothers past came forward and told him that her 10 year old kid is his. They took a dna test and she refused to give him the results. Now several years later (after finding out that him and his wife have a lot of money) she posted online the results. It looks like he really is the dad but there is something off about the results. First the kids name is wrong. The mom put her maiden name as the kids last name. And also the kids birthday is wrong. Off by several months. Could the lab have just made a mistake on the birthday? Or could the test be fake? it really looks real but Inaccurate info just seems to be something that a lab wouldn’t do. And don’t they have to use the lagal name?
Identigene says
Hi, Janet. Here’s what you can do. If this is a legitimate report, your brother’s name would be on the case.
1. He needs to email a screenshot of what the mother posted online to info@identigene.com or fax it to 801-462-1403.
2. He then needs to follow up that email or fax with a phone call to one of our Client Support Representatives at 888-404-4363. We cannot discuss the case with him via email.
If the test was done with IDENTIGENE and it’s a legitimate case, then we would be able to verify it with him.
Now to the other part of your question. Please keep in mind that personal information that appears on the report (child having the mother’s maiden name, child’s birthday) is information that the mother gave us and not a mistake by the lab. Because the test was a personal one and not a legal one, she was not obligated to submit a legal name. Hope this helps and good luck!
Sarah says
I recently took a paternity test for my son and the alleged father the test came back saying he is not the father when I know he was the only man I been with I told him the test came back inconclusive because he has threaten to hurt me and take my son from me if he wasn’t his I know he is telling the truth because he had done so with my daughter I recently made him take another one and will be sending it in tomorrow but before I do so is there any way that I can get a test saying he is I can’t afford to loose my son please I am begging IDC if I have to pay extra money to do so.
Identigene says
Hello, Sarah. We are obligated by law to give the correct results of the test. If you feel threatened in any way, you should contact law enforcement in your area! If you have more questions, please contact our client support team at 888-404-4363 during business hours. We wish you all the best!
Janet says
Thanks for your reply last month. We found out the test was fake. She bought it online and had my brothers name put on it. So it is possible to fake a dna test
Identigene says
Hi, Janet. This is where doing a legal paternity test really comes in handy! With a legal paternity test, a third party supervises all steps of the testing to ensure samples are attributed to the right people.
Francisco Silva says
You say the mom could not swab herself and submit her sample as the alleged father without laboratory experts discovering that. You say that this does occur, you would place the paternity test on hold and contact the participants to ask them to re-swab the correct participants.
My question is: how would you contact the participants? Would you do it by phone or e-mail? I assume you would contact whoever sent in the sample. Please let me know what step you would follow. I think that fraud may have occurred.
Identigene says
You are correct, Francisco. We would contact the person who submitted the sample. If you have further questions, please contact client support at 888-404-4363. Thanks!
Tytiana says
So me and my daughter got swabbed court orders. But the baby daddy was in jail when this took place no one went to swab him matter fact he didn’t know anything about it he didn’t even get test results or anything test came back negative the papers show that the DNA was in fact two years old but from my understanding they was supposed to use fresh DNA and Ik for a fact he’s the dad didn’t separate til I was about 2 months into my pregnancy
Tonya says
Would a DNA sample be considered valid for testing if a cheek swab is done on a sleeping child?
Would it matter if one participant provides a sample in the morning and the other participant provides a sample in the evening?
Please advise. Thank you.
cengerman says
Hi, Tonya! DNA stays the same whether we are asleep or awake and whether samples are taken in the morning or evening. An important thing to remember here is that samples may become contaminated if a participant eats, drinks, smokes, chews gum, etc. during the hour before samples are collected. So be sure that participants don’t put anything in their mouths for a full 60 minutes before swabbing. If a sample is contaminated, the lab will catch it and ask for a recollect, so there’s no danger of it affecting your test results. Hope this helps!
Tonya says
Thank you so much for your response. Yes, it was very helpful.
cengerman says
Great! If there’s anything else we can do for you, don’t hesitate to call.
julie says
My partner has recently had 2 DNA tests that have ruled him out being the biological father to a girl claiming to be his daughter after 30 years, she is asking her doctor to perform a 3rd blood test as she is convinced medication she is taking for chrones disease affected results.. is this possible?
IDENTIGENE says
Hi, Julie. Medication for Crohn’s Disease will not affect DNA test results. Even if medication did somehow degrade a DNA sample, a good lab would catch the problem and ask questions rather than give a definitive result. If two DNA tests have excluded your partner as the biological father, then this girl should probably start researching other possibilities.
mumneeds help says
My friend is having a boy and doesnt want the father involved hes very nasty work (private long story) so has told him he not the dad. Only way he’ll walk away is to see on paper hes not the father.. if she asked her friend to swab her lil boy and partner for a positive result making it look like hes the dad and the ex isnt. And just change names.. Could she get in trouble for this ??
IDENTIGENE says
Hi there! Yes, your friend can get into big trouble should this ever go to court. What she wants to do is definitely paternity fraud. With something as important as establishing paternity, it’s best for all parties to be completely honest.
mumneeds help says
Okay i will tell her this.. even if its a non legal home testing kit ? Would this still get her in trouble ? As iv read that that test isnt aloud in court anyway.. due to if someone did mess with it
IDENTIGENE says
Knowing someone is the father and telling them otherwise is nevertheless a lie, if not legal fraud. It could come back to haunt her later. She may want to contact an attorney to see what her options are.
mumneeds help says
Okay thank u, have told her this but of course shes just worried for her baby. Last question please.. there is a ‘piece of mind’ dna test is that right ? I think she said thats the one not counted by the law as like i said above some people mix samples up so its only the legal test thats taken by law as fraud. I dont know her decision but want to get as many facts for her as poss. Thank you
IDENTIGENE says
There is no way that a legal test can be falsified (and therefore fraudulent) because every step of the process is supervised by an approved, disinterested third party (called a Collector). This Collector checks ID of adults and takes photos of all participants. The collector does sample collection and mails those samples directly to the lab. This eliminates the possibility of switching samples and so this is why results from a legal test are court-admissible. Your last question is a legal one that we suggest you consult an attorney about; we do not give legal advice. I’m sure you understand. Good luck!
Guglielmo says
I’m Italian, i’ve recently had a Dna Test done with my mother my father my brother and me.
The result was that my brother and I are biological children of our parents.
Is it possible that a false positive result has occurred?
I fear that my parents cheated on this test, even if it was a legal test from a University in Italy.
Is it possible that the laboratorists have voluntarily switched dna samples under my parents request and have submitted into analysis another family’s samples With the same sex genes?
hope you can answer me,
Goodbye!
IDENTIGENE says
Hi, Guglielmo. If the test was conducted under the supervision of an impartial third party (which you indicated was done as a legal test), then the results are most likely correct. It is highly unlikely that a reputable lab would voluntarily switch samples.
Edith says
My husband had a paternity test done recently because a woman claims her daughter might be his from 18 yrs ago but there is a.potential 2nd person. Nothing about this seems right as he says he had worn a condom & didn’t break. Also, why now. She knows mutual people. Could of been 10-15 yrs ago. Well he took the test & it says he is the father. We live in different states & she picked & paid for.the testing. There was no chain of command. Is there any way the testing could have been manipulated to show him as being the father?
IDENTIGENE says
Hi, Edith. In most cases of paternity fraud, results show someone is NOT the father. In this case, he most likely is since a positive result is nearly impossible to achieve by manipulating samples. That being said, has your husband seen the results himself? Your husband, as a participant, has a right to see them. If the test was done with us, he can contact our Client Support Center at 888-404-4363 (M-F, 9 AM to 5:30 PM Eastern Time) to get the information for himself.
Peaches says
Hello. My friend has doubts as to whether he is the father or not. I suggested the at home test. However, both mother and child currently reside in a different state. Is it possible to have her do the swabbing done one her end and mailed separately? Or does it have to be mailed at the same time…same package?
IDENTIGENE says
Hi!
The personal DNA Paternity Test kit can be purchased at your local Wal-Mart, Rite Aid and CVS pharmacies. The kit includes all supplies necessary to submit samples for 1 possible father, 1 child, and the biological mother (optional). You can send the collection materials to the person who lives in another state so they can collect their samples, or they can simply buy their own kit to collect their samples.
You can either have the other person send the samples to you so that you can send all of the samples in at the same time, or they can be sent in to us separately. If samples are going to be sent in to our lab from separate locations, we recommend that you call us to pre-pay for the testing so that we can give you a case number to write on all of the specimen envelopes. This will help to ensure that all of the samples are linked to the same case when they arrive at our lab. You can also order a Personal DNA Paternity Test Kit directly from us over the phone and we will send kit supplies to each person directly.
If you have any additional questions or concerns or are interested in purchasing a kit directly from us, please feel free to contact us 888-404-4363 and we will be happy to assist you.
Edward says
I recently did a dna test and the results is that I’m not the child’s father but the mother insists I am and wants another one done. I paid for the test on all three of us and now she claims that since she didn’t get her copy in the mail it’s a fraud. Can the results protect me from any claims? If she takes me to court? Or by any other means? I sent her a copy via text message and still she doesn’t believe it.
IDENTIGENE says
Hi, Edward. “Peace-of-mind” paternity test results are not court-admissible. However, because the mother was a participant she can request a copy from us since she wants to see an original. She needs to call 888-404-4363 (M-F 9 AM to 5:30 PM Eastern) and a Client Support Representative will assist her. Should this go to court, they will most likely ask you to test again by doing a legal paternity test. With this type of testing, an impartial third-party collector checks IDs, supervises collections and then mails them in too. This ensures all participants are who they say they are and therefore the results are court-admissible. Good luck!
advice please says
Hello, can u tell the age from the dna sample ? Think my ex switched my new born son sample with his toddler also a boy. would this come up in result ?
IDENTIGENE says
Hi! Our testing does not determine age. We can only test based on the samples submitted. If you think there was fraud going on, it might be advisable to test again with new samples. You can all test in the same room together and submit the samples together to ensure the correct participants are being swabbed. If your ex lives in another state or doesn’t agree to this, for an additional fee you can have a legal test done whereby an impartial third-party collector checks IDs, supervises collections and submits the samples. If you’d like to arrange a legal test, call us at 888-404-4363 (M-F, 9 AM to 5:30 PM Eastern). Hope this helps!
Kunle says
I did a mouth swab sample and the instruction on the kit says i have to swab each side of the cheek for some seconds. I followed the instruction and then went ahead to swab each cheek side a second time after like 15 mins interval of the first swabs. My question now is, could swabbing each side twice at an interval of 15mins compromise the sample?
IDENTIGENE says
Hi! If you swabbed the same person with the same swab, no problem.
Anthony says
I am 41 years old and been on the hunt for my real father since I found out that the man I thought was my father wasn’t.
About 20 years ago, I met up with him for the first time. He gave me his number and address where he and family was living. Of course, I went and met everyone but he didn’t because she didn’t take finding out about me, his first son, well at all so she wouldn’t let him come down to see me. Then, after awhile visiting and never seeing him discouraged me from going back. But I also figured he would come look for me once he noticed I stop visiting. He didn’t so I still waited BUT also tried to forget and couldn’t… can’t.
Now, I found him again and he acts as if I never existed with doubts… After months of hunting for him and talking to family, we got to talk and agreed on getting DNA tested… It’s been about 5 months since and no luck.. He doesn’t answer his phone, and doesn’t call back… I’m already thinking about trying to take this to Family Court… Should I, or better yet, can I being that I’m 41 years old????
Or what should I do??
This is life top of my list, #1…. to do
IDENTIGENE says
Hi, Anthony. I’m sorry…what a sad story! Unfortunately we cannot give legal advice. I suggest you contact an attorney to see what your options are, if any. Much good luck to you!
Kash says
My boyfriend took ur at home test but when the girl sent the results nothin looked right his name was nowhere on the results and we didn’t even see any logo saying where the results came from…… if she swabbed her brother in place of him would the results still read 99%
IDENTIGENE says
Hi, Kash. Since your boyfriend was a participant in the test, he has the right to obtain results himself. He should call 888-404-4363 and Client Support will be happy to help.
Liz says
If someone takes a DNA test and swaps there brothers DNA instead of the fathers DNA will the results come back positive because there related to the baby?
Identigene says
Hi, Liz. What usually happens (if the man being tested really IS the father) is that the lab would give a 0% probability of paternity (because the man tested is not the father) but mention on the lab report that the biological father is most likely someone closely related to the man who was tested. If you have any concerns whatsoever that fraud could occur when doing a home test, it’s worth the extra money to get a witnessed legal test, which prevents such fraud. Plus, results from a legal test are court-admissible.
rachael says
Hi my question is I happen to have done the wrong thing I done something with a guy and about a week later I ended up doing with his son I ended up getting pregnant….. my question is if there was to be a test done can you tell which is the father? The second guy has kids and my child looks like his kids the first guy has kids and my child doesn’t look like his kids so how likely is the second guy the father of my child thanks I’m very disappointed in myself as for my child is the one to suffer later on in life!!!
IDENTIGENE says
Hi, Rachel. I’m sorry…yours is a difficult situation, but it’s not as unusual as you might think. First of all, you can’t go by looks to determine paternity, especially since the two possible dads are father and son. We can definitely determine which one is the biological father, however. One paternity test kit has enough materials to test three people; in your case we would need DNA samples from the child and both alleged fathers. Because two possible fathers are being tested, you would need to pay the $89 lab fee twice (a total of $178) Be sure to indicate on the order form what the relationship is between the two alleged fathers, so that the lab can factor that relationship in when analyzing results. If you have additional questions, be sure to contact our Client Support Center at 888-404-4363. They can also help set up the test for you.
Paul says
My darther boyfriend showed the cop a Dna test that said he was the father and got the baby my problem with the paper is that there is a state case number, they have never been to court and he is not even on the birth certificate , we now have my grand darther because the two of them are unfit to raise her I do not believe that he is the father and I have not been able to get any information on this state case number . They have never been to court and the child protective services have no papers about this dna tests .l need help thank you sincerely Paul
IDENTIGENE says
Hi, Paul. I’m so sorry about your situation. You definitely should contact a lawyer about the legality of what the alleged father is trying to do, as well as the test papers he showed the police. Good luck!
Summer says
OK my sister, slept with two brothers around the same time and got pregnant. Both brothers have the same mom and different dads. One of the brothers bought an at home DNA testing kit from a drug store. And swabbed himself and the baby and sent it off. The results came back that he was the father. However the child looks a lot like his brother, is it possible the kit can identify him as the father and not the brother simply because they are related? Should they have swabbed himself the baby and his brother for proper results?
IDENTIGENE says
Hi, Summer. If the result came back 99% or higher probability of paternity from an accredited lab, those results can be relied upon. You can never use physical appearance as any kind of indication of paternity. After all, it’s not unusual for a child to look like an uncle, grandfather, cousin, etc.
Yolanda says
I and my son took a DNA test 1 1/2 years ago and the father I listed just took the test Nov 5th of this year. I’m just getting the test result back after 1 1/2, we took it while he was incarcerated. Well, it came back he is not the father. I didn’t know much about paternity testing, so I did some research on my own. I looked up sample test results online and read about them. Well, on our results I noticed where there is a match, 0.00 was the result of the parentage index. I believe I counted 7 to 8 matches but they were not calculated towards the parentage index. I don’t feel like going back and forward with his father, whom I know is the father. I would just like some clarity as to why would there be matches and the matches not be calculated into the parentage index?
IDENTIGENE says
Hi, Yolanda. This is a great question! Were you also a participant in the test? This can make a difference in why a parentage index might be 0.00 if there’s a match. Without having your results in front of me, I cannot give you any definitive answers. Please contact our Client Support Team at 888-404-4363 (M-F, 9 AM to 5:30 PM Eastern) and they will be happy to go over your results with you. Thanks!
Bee says
My child father recently had a test done behind my back but i found out the results they said he isnt the father but he is the only person i had sex with when i conceived we was together the whole time how is that possible something isnt right . i didnt have sex with anyone else and thats the honest truth …
IDENTIGENE says
Hi, Bee. Unless everyone tests in the same room at the same time, it’s hard for you to know if the possible father did indeed submit his own DNA sample. He could possibly have submitted someone else’s and claimed it was his. If he lives locally, you can ask for a retest and witness the cheek swabbing and mailing, so you can be sure the DNA samples are his. If you need results for legal purposes such as child support, you must do a legal DNA test. You can learn more about it here: http://dnatesting.com/what-do-you-mean-by-legal-paternity/
Emma says
My child’s paternal grandfather is asking for a DNA test to prove my child is not his. His son is actually the father of my child and no one knows this. If I do not let the lab know the situation and the grandfather is tested as usual then what r the results most likely to be? Is it going to show that there is a relationship there?
IDENTIGENE says
Hi, Emma. In this situation involving a father and son, it’s critical that you let the lab know that there is a possibility either one of them could be the father of the child. Even if you’re 100% sure it’s the son’s. To get more detailed answers to your questions, feel free to call our experts at 888-404-4363 (M-F, 9 AM to 5:30 PM Eastern).
sheree says
I the father took a Dna test but I ask my mother and my sister to test my suppose to be baby, because I wasn’t around at the time . If one of them swab there own mouth instead of the baby mouth will that results be accurate . They know I desperately want a child so I want to know will that be possible
IDENTIGENE says
If they swabbed their own mouths, the result will be negative. Neither your mother or your sister shares any DNA with your baby’s father. The baby would, however, if the alleged father being tested is the biological dad. Hope this helps!
sheree says
So knowing the baby mother didn’t take the test just me the father of the child did , can any mix up with the test happen , knowing that me and my mom and sister have the same genes
IDENTIGENE says
You, your mom and your sister share genes, but you don’t have all the same genes. You suspect one of them may have swabbed themselves and sent that DNA in as the baby’s? If that happened, the results will definitely be negative. The only way to be absolutely sure the right samples were tested is to all be in the same room when the samples are swabbed, or you can pay a little extra for a legal test, where the whole process is supervised by a third party.
IDENTIGENE says
By the way, if the baby is a boy and your aunt or mother submitted their own samples as his, then the lab will catch it because they test the sex chromosome as well. They will know something is up if they expect to test a boy but determine the DNA profile is a female’s.
jami says
when I went for a dna test that my twins father wanted they took pictures and sent them to him the same day and were really rude to me. and there was no proof yet that they were his could I get the testing place in trouble? and I have not received copies of the results when he has already received them. this was all done about a month and a half ago. he received his in 7 days.
IDENTIGENE says
Hi! If you both have legal custody, then the father had a right to get a DNA test done on the children without your permission. If he doesn’t have legal custody, then he can’t. As the mother, you have a right to see the results.
Mel says
Hello,
I did a DNA paternity test from another company. I was present when the alleged father swab his cheek and I was the one that send everything in the mail. Results came that he was excluded as the father. I started reading bad reviews about that company that people got wrong results. So I did a maternity test with Identigene since the alleged father was excluded he did not wanted to do another test. I wanted to make sure mine and the babie’s alleles matched the first test and they do they are exactly the same. I guess it’s just my nerves that I really want this to be correct. Should I trust this test??my baby does look like the alleged father that was tested but maybe it’s just me!!
IDENTIGENE says
Hi, Mel! I can’t speak for what the other company’s processes are, unfortunately, and therefore have no way of telling you for certain that you can trust the results you were given. I do know that if you test for paternity with us, if we get a negative result, the test is run again by a different technician in order to confirm that result. If there is child support at stake, the possible father can be compelled by the courts to take another test. This would be a legal test where the entire collection and submission process is supervised by a disinterested third party. Hope this helps!
Suzanne Gulley says
What about a case where the mother and presumed father share many markers in common w each other? Could a false positive result from this? Thanks
IDENTIGENE says
Hi, Suzanne. It’s not unusual for there to be markers with common alleles between mother and father. In fact, you and I may share one or more markers in common too. Our scientists look at the whole panel of markers when determining paternity and consider the whole, rather than the few. This is kind of a long way of saying no, a false positive cannot result from this. Thanks for a great question!
Steve says
I am wondering that if my first cousin (male) by my fathers brother has a daughter that he denies and says she is mine, If I have a paternity test with his daughter and her mother will I be excluded. He refuses to have a paternity test. Or will I be possible match because we are first cousins.
IDENTIGENE says
Hi, Steve. The relationship is distant enough that it will probably not be an issue. That being said, you definitely want to include the mother’s sample and make note on the order form that the other possible father is your uncle. This way, the lab will know and take that knowledge into account when giving you your results. Hope this helps! If you have any other questions, feel free to contact us directly at 888-404-4363 (M-F from 9 AM to 5:30 PM Eastern). Hope this helps!
Steve says
The other possible father is my 1st cousin not my uncle. He is the son of my fathers older brother. Does this make a difference?
IDENTIGENE says
Oh I see. Sorry I misunderstood. If the other possible father is your first cousin, that’s an even more distant relationship than your uncle, genetically. I still suggest you make note of it in your testing paperwork so the lab is aware. Good luck!
Cathy says
I need to find out if my father has a son..
My mother is deceased and my father’s alleged son mother is deceased.
Will I get a accurate result as to the two of us being siblings, also my father is deceased .
IDENTIGENE says
Hi, Cathy. What you would need to do is related vs. unrelated testing for a half-siblingship relationship. With so many people involved having passed away, and you and your possible brother having different mothers, it definitely increases the likelihood that you would get an inconclusive result. Because it’s difficult in this type of written back-and-forth to find solutions for you, I suggest you contact us directly at 888-404-4363 (M-F, 9 AM to 5:30 PM Eastern) to talk to one of our experts. They can help figure out your possibilities and give you more details about what you could do, as well as pricing. Good luck!
mahendra says
Hi, i just want to know that the blood samples dna test of my aunty, her 9 years old son and my self will result positive that i am the father of the child as we are relatives….
IDENTIGENE says
Hi, Mahendra. Since the mother of the child tested too, the results shouldn’t be affected by the fact that you and your aunt are related.
patricia says
Hi,my name is Patricia,i just want to know that is it possible for DNA result to be tempered,my sister took the father of his children to court for maintenance,the guy ask for DNA tests,then result came back by email but the guy told the lady in court that he want the result in black and white not by email,so they didn’t open that email and the officer gave them another date.they went back to maintenance court after a 3weeks,they got the result in paper as he requested,only to find out that the result were negative.and my sister insisted that the children are his.can you please advise me on what to do in this situation.
IDENTIGENE says
Hi, Patricia. That does sound like a difficult situation indeed! I’m assuming that since the court is basing important decisions on a DNA test that your sister and the possible father did a legal test? Usually that’s the only kind whose results are court-admissible. With a legal test, an impartial third-party checks IDs, witnesses all cheek-swabbing, and takes charge of mailing samples to the lab. This ensures no one can commit fraud. Did your sister do this kind of test? If she did, then the results were probably accurate.
Melissa says
Hello just got a dna test through a reputable company. My question is they only tested my daughter and her alleged father. They found that he is 99.999999% her father. I am wondering if this could be a false positive considering they didn’t test me.
IDENTIGENE says
Hi, Melissa. The number you gave is the highest percentage possible for paternity. So if you tested with a reputable company, you can trust the results. They would only ask for your DNA if it was needed to confirm results.
concerned dad says
three years ago we were setting up a test to be done to see if a child was mine. my girlfriend and I were told that a dna test was done with the females current boyfriend and that the child was his and that’s why they were back together. than told that we can stop worrying now since the results were in. and to enjoy our lives and an apology for all the commotion everything caused… now last month I received a court ordered dna test for this child. if it is mine is this accountable in court?
IDENTIGENE says
Hi there! Whatever the result shows in the court-ordered test is the one that’s binding, yes. What the consequences are of those test results (financial or otherwise) is determined on a state-by-state basis. All the best to you!
Monica says
The alle gated father took a paternity test with my daughter but didn’t send it I front of me. I know he is not the father can a profile dan test be compare to the previous results?
IDENTIGENE says
Hi, Monica. It’s always best if everyone can be in the same room when testing to prevent the possibility of fraud. If you need results for legal purposes, then collection and submission would need to be witnessed by an impartial third party. If the alleged father is not a legal guardian and did not get your consent for your daughter to be tested, you may want to contact a lawyer. I suggest doing a new test, if the alleged father is willing.
Kymberly P. says
I did a DNA test with the man I thought to be my child’s father and the results came back that he wasn’t the father . my question is can the test result be wrong since my child was swabbed sleeping ??
IDENTIGENE says
Hi, Kymberly. Whether the child was awake or asleep doesn’t change the DNA.
Adam says
Took a test on a child that is 9 years old and it came back not to be mine with Identigene… very devastating… So we took a court appointed one and she came back mine. Explain this!
IDENTIGENE says
Hi, Adam. Whenever the lab gets a 0% probability result, a different technician does the test again to ensure the results were correct, because we understand this type of report can be very devastating, as you mentioned. What we see most often when a legal test shows a different result from an at-home test is that one of the participants submitted someone else’s DNA instead of their own. I’m really sorry this happened, but when we process test samples we take it on good faith that everyone participating has submitted their own DNA. If you have other questions, by all means give our experts a call at 888-404-4363.
Ashley says
My boyfriend was tested to confirm that he is the father of his ex’s son. The results came back excluding him, but he is sure the baby is his. Is it possible that the mother swabbed a child that is not hers or that she swabbed another woman instead of herself, maybe her sister? Would the test catch if it was the baby and the baby’s maternal aunt (pretending to be the mom)? Or would it still show him to be the father? What if she swabbed herself but also swabbed someone else’s baby? Would the test know she isn’t the mom?
IDENTIGENE says
Hi, Ashley. If the baby’s maternal aunt were swabbed, the lab would be able to tell that something is amiss, yes, and ask questions. When we receive samples for an at-home, peace-of-mind test, we take it on good faith that everyone who participates is who they say they are and sends in their own DNA samples. Unless everyone swabs in the same room, puts the swabs in the envelope with each other watching and drops the envelope in a mailbox all together, there’s always a chance that someone committed fraud. If your boyfriend still has doubts, he should ask for a legal test (yes, we do those also!), wherein all sample collections and mailing are supervised by an impartial witness. This way, there’s no chance of fraud. If you’re interested, give us a call at 888-404-4363.
Kim says
If a person switch the father swabs with the child swabs that’s being tested… Will the results show up negative? Meaning, if I place the father swabs in the child’s envelope and the child’s swabs in the one for the father, could the results come back negative?
IDENTIGENE says
Hi, Kim! If the only two people being tested are the alleged father and child, the lab will not be able to tell that samples were switched, unless the child in question is a girl and/or if the mother also participates. A paternity test looks for a 50% genetic match between the alleged father and child. If those matches all exist, it doesn’t matter if envelopes were mislabeled…the results are still that there is a father/son relationship. Likewise, if there is one or more mismatch between the samples, we would consider the alleged father not to be the biological one. Hope this helps!
joshua barnes says
Can chewing gum effect the result of a DNA test?
Admin says
Hi, Josh. It can degrade the quality of the DNA sample but doesn’t change the DNA itself. If the sample is degraded, the lab will ask for a new sample and wait to test till they can use the new sample.
Moore says
My child is from a previous relationship so she does not have the same father as all three of my other children. Their father signed her birth certificate and is now asking to have a DNA test done on my oldest in order to get out of paying child support. Even though he knows he could never be her father. Can he really ask for a paternity test?
Admin says
My understanding is that any man on a birth certificate can petition the court for the right to do a paternity test. What the consequences of that paternity test are depends on the state. In some, the court will order the man on the birth certificate to continue paying child support even if a DNA test determines he’s not the biological father. They do this in order to protect the well-being of the child. If a man signs the birth certificate or an acknowledgment of paternity document (knowing he’s not the biological father), then he’s agreeing to consider that child his own and accepts legal responsibility. I suggest you contact an attorney to see what the courts in your state do under these circumstances.
Cathy says
My husband wants to be the father of my daughter. He’s raised her for 16 years. She heard that he wasn’t her father and wants a DNA test. Her real dad is long gone and wants nothing to do with her. If they take a DNA test and we swab her half brother in place of her dad will it come back as a positive? There is a lot more to the story as to why we want to keep her from the truth. It would ruin her life, and my husband too.
Admin says
Hi, Cathy. What a tough situation! No, it would not come back as 99.9% probability of paternity since her half brother is not her father. You may want to think very long and hard about doing something fraudulent . . . it may come back to bite you and make the situation worse. Just a thought!
Cathy says
I have thought of every situation possible. My heart breaks for both my daughter and my husband. He truly loves her as his own and always has since she was 8 months old. If I swab her brother what would the results come back as? It would show they were related.
Admin says
It could, Cathy, but no guarantee that it would happen since he’s only a half-brother. If the lab suspected a biological relationship based on the analysis of the samples, that would be noted in the report, yes.
Admin says
I know you know this, Cathy. But being a good father has very little to do with genetics and everything to do with the love and nurturing he has shown her for her entire life. Do you think she’s mature enough to understand that kind of reasoning?
Erika says
Can there be a false positive with alleged father and child because if human chimer???? Based on two possible fathers?
Admin says
In the extremely rare case of chimerism, someone who actually is the biological father would generally show as not being the biological father.
Michelle says
What if your mouth or your child’s mouth was not swobbed correctly, can it effect the results?
Admin says
Hi, Michelle! Sometimes it can. But if it did, it would be caught at the lab level and testing would cease. The lab would then ask for new samples before completing testing. So it wouldn’t affect your results. Hope this helps!
Chris says
I purchased the test from CVS. My wife and I have three children a 4 year old boy (my son), a two year old girl (our daughter) and a new born (that we are unsure of). After purchasing the test I swabbed my cheek. Then she did the babies. Later that night she said I put the swabs in the wrong envelope. So she went and got another test. I’m nervous something is up because she desperately wants me to be the father.
After getting the second test we tossed the first one in the garbage. I did the swabs again on myself and let her do the others to the baby. But I didn’t watch or monitor. I also didn’t monitor what she put in the package when we over nighted it.
Could she get DNA from my sons cup, food, something he sucked on or anything like that? I’m nervous that she somehow could get the DNA of my 4 year old son and then the test would come back 100% for the baby.
I understand I can pay for a legal dna test and have it monitor (which i may end up doing) but i just paid $200+ for this test so I’m just wanting to make sure I know if she could fake this somehow or if its not possible.
Admin says
Hi, Chris. Unless you witnessed her swabbing the baby, putting those swabs in the sample envelopes and also witnessed them being dropped off at the post office, there’s a chance the samples may have been tampered with. We only test epithelial cells, gathered from the cheek, so if she tried to somehow collect DNA from a cup, the lab would know and alert that something’s wrong. They would also be able to tell if there are two people’s profile on one swab. If you’re really worried, then, as you say, a legal test may be your best option. If that’s what you decide to do, we can easily set up a witnessed collection in your area. Give us a call at 888-404-4363. Good luck!
Chris says
Hi my results just came in. It says that I am 99% the father.
I’m very excited but to be honest still worried.
Please let me know if there is anyway my wife could have gathered my 4 year old sons DNA other than directly swabbing him. I know she didn’t do this he would tell me. But if she could get the DNA from a toy or cup or something.
Also, my results show ‘AMEL x,y’ this means the samples were from two males correct?
My only other concern would be that she sent in another test that was actually her and my daughter
which would say 99% but its really a test for mother and daughter.
Admin says
Hi, Chris. In my previous comment I addressed your issue with getting DNA from a toy and/or cup. Next to AMEL, there should be an XY for the child and an XY for you, yes. If your wife had submitted her DNA instead of yours or your daughter’s DNA instead of your son’s, then the report would show this discrepancy, yes. Seeing as both profiles on your report are males, I can say, “Congratulations, Dad!” Take care and enjoy your family.
Chris says
Hi again final question. Could my wife have taken the first 3 swabs I did and then had me do another 3 swabs basically testing myself? or would that show up that its just testing DNA of me and not me & the baby.
Admin says
Nope. She couldn’t. Because then the profile for you and the profile for your son would be exactly the same and the lab would have alerted you that something’s wrong. The only two people in the world who have identical DNA profiles are identical twins.
Guglielmo says
Hello,
Is it possible to get a false positive result in a paternity and maternity testing , mixing up the DNA of (for example mother and father ) and comparing them with the son?
I think a light mixup between my father and my mother DNA has occurred.
Thank you!!!
Admin says
Hi, Guglielmo! We check the sex chromosome for each participant, so a mix-up is not possible. Had someone’s DNA sample been labeled as being a woman’s when it was supposed to be a man’s, the lab would catch it immediately, talk to the customer about it, and most likely ask for new samples.
Zachary C. Miller Sr. says
A few years back, I purchased a DNA home test, for me and my son. I followed the instructions, step by step and mailed it in. Upon receiving the results, instead of getting a flat 0 or 99.9%, I received a 56.4%…..and that really confused me. So, I called the lab and asked how this was possible. Their response, was that there was a 56% chance, that I was his father? What does that mean or better yet, how is that possible. The mother wasn’t present during testing, it was just my son and I. Any help with this matter, would be greatly appreciated.
Admin says
Hi, Zachary. If that happened at our lab, we would ask for DNA from the mother to help strengthen results. Did the lab not do that? If the mother’s not available or willing to test, we’ll test additional loci to see if that helps provide a more conclusive result. You may want to ask the lab you tested with about it or just test again. If you have additional questions, you’re welcome to ask them here or call 888-404-4363 to speak with one of our experts directly.
Guglielmo says
Hello,
I wanted to ask another question If it is possible.
The allele call in a DNA sequencing (electropherogram) is done by the software, so it is computerized, or it is done by the laboratorist?
If a laboratorist does not include an allele in the final report , he cannot carry on with the testing or yes?
The software decides whether a alleged allele is a real allele or not?
Thank you so much !!!
Admin says
Hi, Guglielmo! Under the management of lab technicians, all testing proper is performed by robots and software produces data, yes. All our processes have been validated and, as a highly- accredited lab, there are safeguards in place at all times to ensure accuracy. There must be 16 loci generated for each test (plus additional, if they were requested) in order for DNA analysts to then assess and generate a report.
Diane says
Hi
May daughter wad sent for a dna test twice once with blood and one with spit swabs im in SA. The test results for the spit came back negative showing that he is not the father. He is a twin. The next test wad done with someone who cant but wants to be the father. Came back negative the thing that confused me is that the dna samples on the test results for her came back different on each test done at two separate times how id that possible no one here can answer me could it be that the father by conception date and burth date had a false negative due to that I dont know how to count it or tally it or what not I do know that I have spent alot of money on this how can she have two different sets of dna please advise me on how what and why
Thank you
Admin says
Hi, Diane. The child’s DNA sample profile should be exactly the same, no matter how many tests are run. Are these accredited labs you are using? Either errors were made along the way or it’s possible some type of fraud has occurred. You may want to consider hiring a family-law attorney. Good luck!
Wilbert Murray says
Thanks
Andrew says
I was given a DNA test for a child and I am the father. A year later I got a letter in the mail saying I was the father of another child. And I didn’t give them my DNA for this one. Can they just keep my DNA like that and just use it when ever?
Admin says
Hi, Andrew. Were these tests ordered by the court? Who was the letter from? I suggest you contact a family law attorney to see what’s going on.
Guglielmo says
Hello again,
I have 2 more important questions, can you answer both of them please?
First one: a 1:12 mixture ratio must be considered a real mixture ?
For example the main peak is 2000 rfu tall and it is followed by a 140 rfu signal. Is that a real mixture?
Second one: why If a signal peak exceeds a certain height then often there are smaller peaks after it ?
It seems to me that If a main peak exceeds a certain height the following signals are higher than If the main peak is shorter and not that Tall.
Thank you so much for your Patience.
Guglielmo
Admin says
Well hi there, Guglielmo. As a relationship-testing lab, we do not deal with mixtures. We highly recommend you use this book as a reference to help answer your questions or contact a forensics lab: https://www.amazon.com/Forensic-DNA-Typing-Second-Technology/dp/0121479528
Brittany says
Is it possible that the alleged father swobbed himself and his sister (same mother and father) instead of my daughter but said it was her and got back positive results?
Admin says
Hi, Brittany. No, that’s not possible because he’s not her father.
Brittany says
I know he isnt the father but he wont accept it i was already 2 weeks and she even looks and have every feature from the other guy
Admin says
Well, unfortunately you can’t make him accept the results, but they are what they are.
Brittany says
The results said she was his how is that possible?
Admin says
It’s impossible to “fake” a positive result, so he must really be the biological father then.
Brittany says
I was already pregnant before i met him
Admin says
I’m sorry…I don’t know what else to tell you. Positive paternity-test results can only be obtained if the actual biological father of the child was tested.
Luke says
Hi , I recently had a swabbed DNA test for a test to see if my daughter was actually mine , turns out I wasent her biological father but when my daughter had her test someone come to the house an only swabbed for at least one an half mins ..then I had mine done by my GP an he swabbed each side of my mouth for a good 5 mins maybe more .. is ther any chance it could of got contaminated in anyway , I know people say looks doesn’t make the child yours but this child looks like me an my family members it’s crazy an hard to get over … any advice is welcome thanks in advance
Admin says
Hi, Luke. If you used an accredited lab, you can trust the test results. If there hadn’t been enough DNA on the child’s swab to get a good enough sample, the lab would have asked for a new sample from her. Improper swabbing doesn’t affect test results, because DNA doesn’t change if it’s contaminated…it just might affect the quality of the sample. But in your case, it sounds like it didn’t. I’m sorry you’re disappointed in the results…that’s always rough.
Arnold says
my sister and I had a dna test …my dads sample was collected in the states ..I and my sister s sample were collected here(ghana) by an authorized physician at the same time . ..the dna test was done …the results come back negative (0.0) that my sister isnt a biogical child of our father mine was positive thou..my mothers has claimed that my dad is the biological father of my sister ….she has sworn to my dad and family members letting us know shes been honest. ..my sister and I both have the same birth mark on our dad ….is there a possibility that the results may be positive when its done the second time.
Admin says
Hi, Arnold. Seeing as your sister’s and your samples were collected through an authorized physician and your results matched your father’s, it seems unlikely that there was anything amiss with the testing samples and you can trust the results. As for the birthmark, it depends on what it is…some are common in the population at large and you therefore can’t make the assumption that you got it from him. Is there also a possibility that your sister’s biological father is related to your dad? Some things to consider…
Tiffany says
Hi is the child is a girl and 2 of there swabs the suppose father swabs got mixed togather what will happen
Admin says
Hi, Tiffany. Our lab tests for gender, so if the swabs are mixed up then the lab will pick it up right away. If swabs are contaminated by having two separate people’s DNA on the swab, then the lab will ask for a new sample collection. Hope this helps!
Ray says
Hello, I have a son that has dark skin and Brown eyes. Myself and his mother have blue… can this be right or should I take a paternity test? We both are light skin people.
Identigene says
Hi, Ray. If you are both carriers for the dominant brown-eyed trait, then yes, it is entirely possible for your child to be brown-eyed even though you both have blue eyes. The same goes for the dark skin. Of course, a paternity test would resolve your doubts once and for all, so if you have reason to suspect you are not the biological father, it wouldn’t hurt to do one.
Annandi says
Good day,
Can the DNA test results be sent by email? Is it a good thing to do?
The alleged father and son did the test, the wife is not the biological mother of the child. But the test results got sent to her by email. How possible is that?
The results came out saying the “alleged father” is not the biological father.
Identigene says
Hi, Annandi. For specifics about a case, you’ll need to contact us directly at 888-404-4363. Thanks!
Markia says
Hello I wanted to know have you had any cases where the baby looks like the potential father but he denies it and the paternity ended up saying that he is not the father
Identigene says
Hi, Markia! Looks are never an absolute determinant of paternity – only a DNA test can make that determination. A lot of people share similar physical characteristics even if they’re unrelated.
Kadie says
My fiance has an ex girlfriend who claims to have a child that he is the father of. His mother talked to her mother and her mother said she was never pregnant. This girl still claims there is a baby and has sent pictures. We are going to get a court ordered DNA test. If the so called mother was in fact lying about the baby is there any legal action we could take against her?
Identigene says
Hi, Kadie. We are not legal experts in that area, so that is a great question for a family-law attorney. I wish you all the best!
Emily says
Long story short I have 2 kids from a previous marriage, my last is not. The possible father and I did a store bought DNA test and after we swabbed everyone he took the stuff and said he sent it off. He changed the passwords to get the results, but the paper he gave me says he is the father, however it is not signed by anyone at the bottom. I had to do a DNA test on my last child to get my divorce to prove he is not my ex-husbands. When I look at the results for my sons numbers they are not the same numbers from the paper I was given. Shouldn’t my sons numbers from his column be the same on both test?
Identigene says
Hi, Emily. Yes, your son’s profile should be exactly the same. Something is up! I recommended contacting a family-law attorney and insist on having him do a legal, witnessed test. When you pay a little extra for this service, results are court-admissible and paternity fraud is impossible. Good luck!
Yanara says
Hello Goodnight. The paternity test could be done with samples of the alleged father and child
Identigene says
Hi, Yanara. The answer is yes.
Kia says
I just got the results for the DNA test but there’s no name of the father or child on your why isn’t the names on the DNA test kia
Identigene says
Hi, Kia. There aren’t names on the at-home test because we cannot verify if the participants really are who they say they are. We do list the participants’ roles in the test, however, so you can tell them apart: for example, “alleged father” and “child.” When the test is a “legal” one, meaning that an approved DNA collector checks participants’ IDs, witnesses collections and submits samples to the lab, then the test report contains names.
Kandi says
Hi my father is incarcerated and for 20 some odd years he has and also my mother said he is my father we took a dna test at home and he sent cotton swabs in a envelope from the prison and I feel like the results were wrong because I look just like his mom. Could this be a a error on his part
Identigene says
Hi, Kandi. If you used an accredited, well-regarded lab for testing (like Identigene), then you can be sure the test results were correct for the samples the lab was given. Unless a prison official witnessed him collecting his own DNA in the prison, there is always a chance he may have submitted someone else’s DNA instead of his own. Something to consider…
Safari Redmond says
Hi. I have bought the Identigene Dna paternity test with the $89 lab fee. Once i get the results will the names of the child and father be on the test? I did the test for my boyfriend and his child with DDC and we didnt get results with their names which doesnt show anyone that there is proof.
Identigene says
We only put names on legal tests where DNA collection is supervised by an impartial witness. This is because, with home tests, we have no way of verifying if participants are really who they say they are on the paperwork. The testing process is exactly the same, and the numbers assigned to the samples are bar-coded and tracked all the way through, so you can still be sure results are for the right people. There just aren’t any names on the reports.
Jerry says
My girlfriend had a DNA text done with her ex is there any way they could have swab him and his other kid instead of the one in question and her it cam back 99.0 jw
Identigene says
If the two children are the same sex, then yes, that kind of fraud is possible. If test participants have reason to worry about the honesty of the others, then they should insist on getting a legal, witnessed DNA test done: https://dnatesting.com/how-the-paternity-test-kit-works/paternity-test-for-child-support/
Brandy Herring says
Could a mother swab her son and daughter to show the son being the father to get a positive result?
Identigene says
Hi, Brandy. The answer is no, because – although siblings do share some DNA – siblings don’t share a father/daughter relationship, and the testing would show that.
Daniell says
The alleged father of my baby came over and we all swabbed our own cheeks. He then took the samples and didn’t mail them until a week later. He had plenty of time to tamper with it. Is it possible that he could of swabbed his son who has the same exact name and replaced his sons DNA with his’? If he was the father and he swabbed his son instead of himself can my daughter and his son share dna or would it come back 0% since both kids have different moms.
Identigene says
Hi, Daniell. If the alleged father did that, then it would come back 0%. When doing paternity-testing at home, it’s advisable to do EVERYTHING together, even mailing. And this is why. You have no way of knowing whether or not he tampered with them.
Jevon says
The alleged father sent me(alleged child) a copy of the dna results. Was wondering if there was a way he could have altered the results on the pdf before forwarding them to me
Identigene says
Hi, Jevon. I’m assuming this is a home test and not a legal, witnessed test, correct? If so, unless you see the original, that is always a possibility. If you need results for legal reasons, insist on a new test and have it be a legal one. Feel free to give us a call for more info, OK?
NK says
I live in New York. From the beginning, I asked for the court to grant me a DNA test and they did. I paid and was scheduled for DNA test in North Carolina by the court, I paid for a two-way where the Mother, Child and Dad are tested, the decree had said that the test should be done at the same time at the same facility in no more than 20 miles from the minor’s residence, the closest would be at a particular location.
I showed up at the facility for a different lab (not yours) , an hour earlier before the appointment time, Thursday 19th at 2pm.
At 2pm the nurse called me in and asked me if I had to wait on or deliver my sample and I said I will have to wait on the child and her mom. By 3pm they had not showed up and again the nurse asked me – I said call them- she tried to call and there was no response and so I did not deliver my sample given that they had not showed up at the facility. In my knowledge, I believed they had not taken or delivered a sample.
In October, 9 the lab employee calls me to advise them if I still want to go ahead or cancel the case?
I said,
“don’t! Another court case is Dec. 10, 2015, they’ll either have to come and do the test. Because, they did not oblige by the court rules, the court decreed that they have to take a DNA test which they did not.”
Then the employee said, “I will keep on hold.. please keep me posted.”
Then when I asked about the refund that’s when she revealed that the child and mom had already delivered theirs.
I said
“All along I knew they had not delivered, because they missed an appointment when I was there. Unless you’re making me get suspicious. When did they take it? Was supposed to be a two way, did you follow the instructions? Up to this time I knew that they had never taken it. Then why did you ask me to cancel in October when they had taken it?”
So that’s when she gave me an appointment to a New York office.
Well, after two weeks the results turned out to be positive and the court looked at it. But because of all the confusion and dilemma in delivering the samples, I was not comfortable and asked for another DNA test which I was not granted by the court, no child custody no rights to see the child other than Skype. Do you see anything fishy/falsity in this case? Now they are asking for child support.
Identigene says
Hi, NK. We really cannot comment on other labs’ processes and whether or not anything seems fishy, since we don’t know all the details of the case. You may want to contact a family-law attorney to get their opinion. Good luck!
Araceli says
My now husband has an ex who he has a child with already and now she had a new baby and she is claiming the new baby is his as well ( I doubt it ) but is it possible for her to use her daughter’s ( which is also his daughter) dna test for the baby just to get a positive result and use it against him? Or are you able to identity if someone did that
Identigene says
Hi, Araceli. Is the new baby a boy or a girl? If it’s a boy, then the lab would catch if she’s using her daughter’s DNA instead of the new baby’s. If it’s a girl, then the lab wouldn’t be able to tell whose it is. I recommend that he do a legal paternity test wherein the DNA collection is witnessed by an impartial party. He just needs to call our parent company, DDC, at 800-681-7162 to set that up.
Beth says
Baby has an extremely abusive dad. He is forcing dna to get custody. Is it possible to scrap my mom and rub it in baby cheeks to throw off dna to protect child
Identigene says
Hi, Beth. No, that is fraud. If there is abuse in the case, the best way to protect your child is to hire an attorney.
cindy says
I want to know if what is the result of avuncular dna testing.. the sample came from mother, son and aunt(sister of allege father)… will the 90% result the highest result for this kind of dna testing?. is there any chance that a dna sample came from mother, son and aunt will give a result of 99.99% or 98%?
Identigene says
Hi, Cindy. 90% or higher is considered conclusive for this type of relationship test. Super-high probability of relationship is unusual, especially when testing a male child with an aunt. If the test were with a male child and the full biological brother of the alleged father, then the result could be 99.99%. This is because a Y-STR test would show whether or not the male child has inherited the same Y chromosome that is passed down from father to son in families.
cindy says
with a 90% avuncular dna test result , is there any chances that the child is a son from the cousin of the aunt?.. .
Identigene says
No. They wouldn’t share enough DNA for the probability to be that high.
Gail says
Can a dna test be only 1 marker off if sister and brother have two different fathers one being a black man the other white mom is white?
Identigene says
I’m sorry. I don’t understand your question. Can you please clarify? Thanks.
Armanda says
So if I get my DNA done and my sister has her done. Will that tell us if we have the same mother and father.
Identigene says
Hi, Armanda. Whether or not you get conclusive results depends greatly on the genes you and your alleged sister happen to share, so I can’t give you a straight yes or no answer. If the father isn’t available to test, it’s much better if the mother can contribute her DNA. You’re welcome to give us a call and talk to one of our experts about your options: 800-681-7162.
Amanda says
Im married have kids when I was pregnant one guy live with us. I thought my kids was my husband. He said that’s his kid. He trying to separate me from husband and kids. And he filed case against me. If I was in unconscious stage may be if he used physically myself. May I have possible chance of pregnancy? Or if I go dna test I don’t know how is the result come? Negative it will be fine. If positive I don’t know what I do. I don’t like to leave my husband or my kids from me. I beg u please give some advice for me. How I handle this situation, court order said I need to take dna test. I wish the result come negative please msg me.
Identigene says
Hi, Amanda. If the court order says to do the DNA test, you should do it.
Mitzy says
So my daughters dad asked for a DNA he already went to the lab to get his done I just have to take the baby but my question is I live in Las Vegas , and my daughter has my last name if it comes back that he is the dad which he is would I have to change her last name
Identigene says
Hi, Mitzy. That’s a question best answered by a family-law attorney in your area.
James says
Years ago I was tested for a child while I was incarcerated. The child’s sample was taken in the free-world, while I had blood drawn at the prison hospital. The test excluded me as the father, but the mother (now deceased) told me that she was trying to save me from having to pay back child support when I got out, so at the place where her daughter’s sample was taken she allowed the collector of the sample to take her other (similar aged) daughter’s sample who she knew had no possibility of being my child. It sounded believable because small children often times don’t have photo ID, and I would think that the process would be set at the Department Of Health And Human Services, then the mother would go to the hospital to get the blood drawn/mouth swabbed,,and the nurse would simply gather the sample from whoever the mother said is to be tested. A picture was included with the documents I got, but not sure this was taken by the nurse. The child is an adult now, but still hasn’t had paternity proven which supports that what her mother told me may have been true. What can I do legally to find out the truth of whether I’m the biological father or not? Thank you!
Identigene says
Hi, James. If the adult child agrees to testing, then you can test with her. If she doesn’t agree, your best option is to contact a family-law attorney and see if you have grounds for a court ordered test.
Nathan says
Hi ! I think my ex used her older sons DNA to match with his sisters instead of mine to hers. Can I sue ???? It came back positive. But I want another test done.
Identigene says
Hi, Nathan. Testing a brother with his sister would not yield a positive determination of paternity. After all, he’s not her father!
Kay says
Can swabs be taken of mother and father only ? Will mother share dna with father of child unborn
Identigene says
Hi, Kay. Unless the mother and father are biologically related, the amount of DNA they share would be very small and no more than what you see in the general population. I’m a bit confused at your situation. Is the child unborn or born?
Cur says
The alleged father has done a DNA test with another child with you. Can I submit my swab and my child’s swab with the results of his test and compare it? Or if you already have mine and the child’s swab, is it possible for you to use those without sending anything else in?
Identigene says
Hi, Cur. What is your role in the test? Mother for another child with the same alleged father? If so, we would need him to resubmit his DNA. For security reasons, we do not keep data on file for long if it was a home test.
Cur says
I am the mother. If I have his dna test with me, is it possible to compare his alleles from that one to a paternity test I did with another child and potential father which came back as an exclusion? He would be the only other possibility but I’m having a hard time believing the exclusion based on how much she resembles the guy who was excluded. I know looks don’t determine paternity but my other two kids are twins and even people will say the two who look alike and the “oddball” don’t even look related, but they all have the same father according to the exclusion of our paternity test. I’m just trying to get peace of mind and not hurt anyone if I don’t need to.
Identigene says
The only way to be absolutely sure is to do another paternity test with the man in question. Even if there are a couple of mismatches when you compare the data yourself, they could be mutations and he may still be considered the biological father. Professional analysis is the way to go.
Cur says
What if I compare and they match everywhere? Because I have done that and the child at each marker received an allele from me and from the alleged father compared to his other test. The only thing I am curious about is why are there a couple different markers on his paternity test compared to ours? For example: Penta E is on his, not on ours. But every marker that was the same matched.
I also just posted another comment because I did not see my other one posted yet until now. Thank you for responding.
Identigene says
It could just be that one of the labs tested an additional marker, perhaps for conclusivity reasons. I consulted with one of our PhDs about your other question, just to make sure I was giving you correct info. If there was a match between the alleged father and the child at every single one of the SAME loci, then you can make the assumption that he most likely is the biological father. However, to be on the safe side, you should have the data looked at by a DNA lab.
Lisa says
I have a question. If I am the one ordering the paternity test; who else is able to obtain those results? Can they be viewed by others? Example the other person being tested? Or do I forward those results to the individual. By the way its not for legal purposes and child being tested is over 18…
Identigene says
Hi, Lisa. Because it’s a non-legal test, only the decision-maker in the case has access to results. He/she is the one who provides an email address and password and is able to see the online report. The decision-maker is welcome to download the report and share it.
Steve says
I have two questions..first your laboratory states they run every test twice(at least for test resulting in exclusion) for assurance in accuracy of results. Is this dual testing done just for legal paternity test? Or is it for all test including home paternity test? And second question is your lab is accredited with aabb and other agencies…but does that apply to home DNA test? Because according to aabb it does not…just trying to understand how your home paternity test is treated the same as legal test in lab
Identigene says
Hi, Steve. Great questions all. Our extraction and analyses processes are exactly the same for at-home tests as for legal ones. We do run every postnatal test twice, both for inclusions and exclusions. The main process difference between at-home and legal is in how the DNA is collected. Although our lab itself maintains a full battery of accreditations, the at-home test cannot be accredited by the AABB, since the identification of participants cannot be verified. Hope this helps! You can see our accreditations here: https://dnacenter.com/about-ddc/accreditations/
Peace says
I have just had my son’s paternity results which were recommended by the child maintenance options. I went to my GP with my son whilst I understand my son’s father went to his GP to have our samples taken. What baffles me is that the results came back stating he is not the father which is not true because I know and my son’s father also knows he is the father although he has challenged this as he did not want to pay child support. I was in a relationship with him alone at the time I conceived and have never entered into another relationship since we separated over 10 years ago. I am so sad and I need answers as to why the result is negative as I trusted that the GPs would verify the tue identification of each sample giver. I also trust the testing company as they appear to have a good reputation.
What could have gone wrong here? What can I do next? Can I challenge the test results and how do I go about this?
HomeDNA Identigene says
Hello, Peace. You didn’t mention whether the test was set up as a legal test. Do you know if it was? With that, the testing materials would come directly from the laboratory and IDs must be checked. None of the steps in this process is voluntary…each is a must.
Tiffany says
Hi, when I was younger there was a DNA test done between two potential fathers, one of them went in the same day with me and my mother, we’ll call him Jake, and the other went in a month later, John (he was the one who demanded the test) Well the DNA results came back as Jake 50% and John 90%. How is that even possible.
HomeDNA Identigene says
Hi, Tiffany.You didn’t mention how long ago the test was, but it had to be quite a while ago. Accredited labs no longer give results like this for paternity tests. Now, the technology is so good that it’s either 99% or higher or 0% probability of paternity. Neither of the results you gave would be considered conclusive now. Even if you weren’t related to Jake at all, it wouldn’t be unusual to show some percentage, since as humans we share a lot of the same DNA. I’m curious if the lab’s conclusion was that John is your bio father or neither of them.
Latrell'e says
Is there any way my sons step mother could have swabbed another child with the the same swab for my son, to yield a negative result be cause there’s a lot of numbers that are the exact same and some are only off by a couple of numbers so I just thought I’d ask because my son looks so much like the man who took the test and not the other man that I have yet tested and these rwom men look nothing alike.
HomeDNA Identigene says
Hi, Latrell’e. Physical resemblance is usually a matter of opinion and is never an absolute determinant of paternity. The fact that some numbers are the same is not unusual at all. In fact, you and I probably share some of the same numbers at the same genetic locations even though we’re not related. What does have to happen in order for a test to show a positive paternity probability is for there to be a match between the man tested and the child tested at every location. If you did an at-home test and didn’t witness the stepmother swabbing the child yourself, then there is a possibility of fraud. You may want to consider testing again, but this time doing a legal test with court-admissible results. With this type of test, IDs are checked.
Joe says
Hello if my daughter’s mother took the wrong child in for r DNA testing on purpose so that it would come back as I am not the dad what can happen to her? Because I have a funny feeling that my ex took her six-year-old in instead of my 5 year old for the DNA test and What can happen to her if she was found to have done that
HomeDNA Identigene says
Hi, Joe. Was this a legal, witnessed test with court-admissible results? Because that makes a difference.
Laurie says
My husband had a home paternity swab test done back in early 2002. I have searched high and low for the results we received and have misplaced the box with all the paperwork we dealt with due to the situation. I believe that the name of the lab was Identigene, and was wondering if this is the correct lab that did the test, could my husband somehow get a copy of the report showing he was not the father of the child in question. We feel we must prove ourselves to this young adult that we did have the test done because she has been told otherwise.
HomeDNA Identigene says
Hi, Laurie. Yes, it was likely us. For security reasons, results of paternity tests are kept on file for only a limited amount of time both online and in our records. This is why we make reports downloadable PDFs, so customers can save them externally for their own permanent records. I’m afraid we can’t help you, since the test was so long ago, and you’ll need to do another.
Steven says
What would happen if the potential father and baby’s samples were mixed, e.g. baby’s were marked as father and father’s were marked as baby? Would this result in a negative finding of paternity? Or if the man is the father would it still show up as a match?
HomeDNA Identigene says
We don’t test for age, so if the baby is a male, we would not be able to tell which is the alleged father and which is the child. Either way, we could still establish a paternity relationship, of course. If the baby is a female but the samples are marked as being for the alleged father, the lab suspends testing and reaches out to the person responsible for testing in order to get clarification before proceeding.
David says
When I tested myself with my two kids I accidentally placed the swabs from both children into the same envelope. I then removed the two from my daughter and left my son’s in that same envelope. I placed my daughters swabs into a new envelope and sent them in. Is it possible that the test could have been incorrect because of this cross contamination? The results did show that one was mail and one female so I’m assuming you guys figured it out and that their accurate results. I just want to know if I should retest because of this.
HomeDNA Identigene says
Hi, David. Our scientists can tell if there are two people’s profiles on one swab. If any cross-contamination had occurred, testing would have been suspended immediately and the lab would request new samples. Since you were issued results, contamination wasn’t an issue.
Alice says
Dna paternity test was done on my granddaughter by a man who was potentially the father, but he was not on the birth certificate and is in no way the legal parent or guardian. He and his mother bought a test and did it without the mother’s knowledge or consent. How were they able to do that if her consent is required? Isn’t it a HIPAA violation for them to obtain her genetic information without the legal right to that information? Turns out he was not the father biologically either. There was no court order either. It was a home test done without her even knowing.
HomeDNA Identigene says
Hi, Alice. For a home paternity test, there’s no way to verify whose DNA the possible father submitted for testing, which is why our company doesn’t include names on at-home reports and also why results of these types of tests are not court-admissible. In other words, there is no way of knowing if this man submitted DNA for the child in question or for a different person. The man definitely wouldn’t have been able to get a legal (witnessed) paternity test with court-admissible results performed, however. For this type of test, identities are verified along with verification that the man has legal authority to test the child.
Alice says
I dont care if it is used in court or if you put her name on the report. Genetic testing requires parental consent. Your website even says the mother has to consent. Are there consent forms that were submitted for the testing to be performed? I am assuming he had to sign something.
HomeDNA Identigene says
It does matter if results are court-admissible. As I mentioned, we have no way of knowing if the DNA he submitted as your child’s really is your child’s, and so for home-testing, the burden is on the customer to ensure he has all necessary consents. For court testing, the burden is on the lab.
Maiky says
Hi, I have a few questions regarding a paternity test that I had done with my child.
1. Is the cheek swap test accurate?
2. I had done a paternity test which resulted positive of me being the father. However, I (father) basically gave my baby a kiss in the mouth 20 mins prior of doing the paternity test. Could that kiss, that I gave my baby affect the accuracy of the test in terms of it being positive because I believe by me giving the baby a kiss I understand “think” that my Dna was present at the time. Or, because it was a Swap does it mean it was not affected by my giving the kiss to my baby?
3. Is 99.97% considered a high positive with a Cpi of 4,635?
4. In the sample they collected the swap of only me (father) and baby.
HomeDNA Identigene says
Hi, Maiky.
1. Yes, DNA is the same whether it’s collected for testing from a blood sample or a cheek swab
2. The baby’s sample was not affected by your giving the baby a kiss
3. Had you done a legal test with court-admissible results, the results you were given would be considered conclusive by the court
4. The mother’s DNA is not usually necessary to obtaining conclusive results in a paternity test, which is definitely true in your case
Hope this helps!
Mika says
Can someone else call to ask for a hard copy of the results if they have the case number? Or only the person who sat up the account
HomeDNA Identigene says
Hi, Mika. Only participants in the test can request a hard copy.
Melody says
If a grandfather and grandson were tested ( because the father was unavailable) and the first test came back that there was no chance that the baby was the unavailable fathers. Then they were told that they tested the the grandfather as the father and had to retest. The second test came back that the unavailable father was the father. Wouldn’t the first test show some family markers.
HomeDNA Identigene says
Hi, Melody. Without your report in front of me, it’s hard to comment on the specifics of the “family markers” you mention. Chances are very good that the grandson and grandfather share a lot of the same DNA, but that’s not the question the lab was asked to answer. The question the lab was asked to answer was, is this man (who was actually the grandfather) the biological father of the child? And the answer to that question is no.
