True, False Road Sign

Questions About Participant Sample Fraud

We continuously receive inquiries from customers questioning if it’s possible for one participant of paternity testing to switch samples, either with themselves or someone else, or if they could have changed the DNA somehow by eating before collecting DNA.

A paternity test can take an emotional toll on some. So let’s address this question one scenario at a time.

Mom submits her DNA as the alleged fathers sample for Paternity Testing

True or False Paternity Test Samples

One question we encountered recently was a concerned alleged 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 would 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 fathers 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.

Alleged Father Switches his sample with someone else for a Paternity Test

Another question I often 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 can not verify whose sample 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. This is where all participants go to a third party collection facility to have their DNA collected by a third party. The collector will verify 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.

Eating or Drinking before DNA collection in Paternity Testing

One last situation I want to discuss is the question of whether someone can alter their DNA by eating or drinking something before they swab their mouth. The answer is no. You can not alter your DNA with putting anything in your mouth. If you have had a bone marrow transplant recently, that may come into account. 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, and this is 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 need to recollect samples for the participant for re-testing. The first recollection is always at no charge to the customer here at IDENTIGENE.

  1. Hello. My husband got custody of his son from a previous marriage a few years back. When this happened his ex-wife told him that the boy was not his biological son. She suffers from mental illness so no one believed her at the time. Some things have come up and we started wondering if she was telling the truth. We did the dna test on my husband and stepson and I got an email saying the results are inconclusive. Shes not that involved and honestly my husband does not want to involve her so getting a swab from her is not possible. We haven’t gotten the percentage back yet but if we retested is there a chance that anything could change? Thank you.

    • Hi Nikki,

      If restested, the results would most likely not change. The only reason the results would change would be if the mother could be included like you indicated. When the mother is included, it is highly unlikely that results come back inconclusive, meaning you will usually get a yes or no answer. It sounds as if this is not an option at the time though. One other small possibility is that the DNA collected for the child and the father may have not been a full profile–say the whole DNA profile was not included because enough DNA was not collected. Although this is probably not the case, you could call about the specific case and we could further advise you about the possibility of getting a more conclusive result. Our friendly client support staff would be happy to help you with this. Our office is open Monday-Friday, 9 a.m.-8 p.m. ET at 1-888-404-GENE.

  2. My sister in law is wanting to do a home DNA test. She’s wanting to know, for her daughter. If we can swab her daughter herself, and I because she believes my uncle may be her father. We would swab him but last I know he moved out of state an I haven’t spoken with him. So is there anyway I could be the replacement.for him?

    • Hi BVanessa,

      In order to establish paternity, we will need the alleged father’s DNA or first degree relative (parent or sibling) DNA of the alleged father. We suggest having your sister-in-law contact us and we can help her decide which testing will work best with who is available for testing. Our phone number is 1-888-404-4363 and we are open Monday-Friday ET.

  3. My mother is deceased, If I have dna results from when I tested my son, which shows my dna on there also and I have my father swab for his dna, could my mothers dna be determined from that?

    • Hi Lola,

      We may be able to help you with what you need. It would be best if we could talk to you to better understand what you need and the best way we can get you that information. Please contact us at 1-888-404-4363. Thanks!

  4. Hi.
    So I have a case to where my child’s father paid someone else to go antake the DNA for him. I know100% that rhis man is my little girls dad. They tool a picture of this man an ot was not Chris. My ex. Its a little hard to see bc its black an white but you could see our picture juat as clear as day. Also the sigurtures did not match up. I do have a lawyer. I want all 4 parties to go in at once an do the testing together so I can make sure he don’t try an pull this stunt again. An why is cheating on a DNA no against the law? Can my lawyer his lawyer. My self an him with our child take this test togther?
    Thanks Joanna

    • Hi Joanna,

      It sounds as if you had a legal test done, but the alleged father may have found a way out of getting an accurate test if he had someone else go take the test for him. With IDENTIGENE, the collector does receive notification of whose sample is to be collected. The collector will verify that the name we provide them with matches the name on the ID and that the photo on the ID matches the person who is there for testing. Obviously, there are illegal ways people can get around this and to answer your question, it is illegal to cheat on a legal DNA test. We would suggest speaking with your lawyer for further advice and to decide what your best option from here is.

  5. Ok I have a question 5 yrs ago I had a baby I slept with two men, I did the identige test with one of the guys and it came back that he wasn’t the father…. I strongly disagree with the results because the dates don’t match up with the other guy . Also the night before we took the test in the morning he had drank alcohol . Can alcohol give in accurate results??? Or it doesn’t matter ?

    • Hi Ashley,

      Although timing is sometimes a good indication of who the father could be, it’s not always reliable. The results you received from your Identigene paternity test are 100% accurate as long as we received his correct sample to our lab, and not someone else. In regards to your concerns about alcohol contaminating the samples, you need not worry. Any food or drink that is found on the sample simply inhibits the labs ability to extract DNA–it does not change the DNA. If we do find that the contamination doesn’t give us enough DNA for testing, we will contact the participants to recollect the samples. If you have any other questions or concerns please feel free to ask or you can call us at 1-888-4004-4363. Thank you!

  6. I wanted to know do the dna results reads the race and gender of everybody OR just the parents ? Does dna shows if the child a male OR female ?

    • Hi Tasha,

      We test for gender on each participant, so yes it does show if the child is male or female. Please let us know if you have any other questions. Thanks!

  7. If the alleged father doesn’t want to take the test but his mother is willing to would take the test. Would the results still come out the same

    • IDENTIGNE’s in-store, retail kit is for paternity determining only. Without the father’s DNA, we cannot establish paternity in a paternity test. This means if the mother and the child swabbed in a paternity test, we would contact the participants to collect from the father. If the father was unwilling to test however, you could call IDENTIGENE at 1-888-404-4363, to set up a family reconstruction test. In this test, the mother, child and member/s of the father’s family test to determine a relationship.

  8. Can the test results say there is zero percent he is not the father be wrong because the mother wasn’t tested with them and the child inheirted most of their genes from the mother??

    • Hi Nichole,

      No, if the probability of relationship is zero percent, he is not the father, even if the mother was not tested. If we are unable to come to a conclusion to if he is or is not the father, you would have received an “inconclusive” result. This simply means we were unable to get solid results to if he was or was not the father. A zero probability of paternity means the father’s DNA did not match the child’s at most locations on the DNA. All humans have some similar DNA, so the two probably had some matches, but this does not mean he is the father. In addition to your question about the child inheriting most of his DNA from his father, the child inherits half of his or her genes from her father and half from her mother. If you have more questions about your specific test, please call IDENTIGENE at 1-888-404-4363, and they would be happy to explain your results further. Thank you!

  9. Can Listerine affect the results of a DNA test?

    • Hi Brandon,

      No, Listerine will not affect DNA test results. There is a possibility that it may inhibit our labs ability to extract DNA from the sample, but if your test results were released, this means that we were able to extract enough DNA for testing. If however, we aren’t able to gather enough DNA due to contamination from things like Listerine or food or drink, we contact the participant about recollecting the sample. If you have any further questions, please contact our friendly client support at 1-888-404-4363. Thank you.

  10. If I use an at home DNA test and swap my dna for the possible fathers would it come up that he is the father? Because I used my dna?

    • Hi Kristen,

      No, he would not come up as the father. We check each sample for gender. Our lab will detect if the mother used the father’s swabs. Hope this answers your question.

  11. I know we have to follow instructions carefully but what happens if the alleged father is swabbed for both himself and child? Does it show up as a match or how would we know of this error of simply not being careful and paying attention?

    • Hi Natasia,

      If the father’s samples were sent in as both the father and child samples, we would detect that the DNA profiles came from the same person–we would not interpret it as a positive paternity test. In this case, we would contact you for re-collection. Unfortunately, recollection extends the length of the process because we will need to send out new swabs for the child and then you will need to send them back in. If you are concerned that this has happened, we recommend contacting our friendly customer support staff and inform them so they are able to expedite the process and get the new sample swabs to you faster. 1-888-404-4363. Hope this helps!

  12. My 1 year old was swabbed and was hiding a piece of roast beef from hours before in his cheek (it was extracted with the collection swab). Would this have an effect on results?

    • Hello TJ,
      It is important the participants do not eat, drink, brush teeth, or smoke for at least one hour before the test. In your case, there is a possibility that the samples could be contaminated with food, drink, blood or even from smoking, but we will be able to detect any contamination once the testing begins. The DNA itself cannot be changed by contamination, so if the samples are not contaminated by food, the lab will be able to process the testing and produce an accurate result.

      In the event that the samples are contaminated, we will contact you and will send a free recollection kit in the mail. I hope this information is helpful. Let me know if you have any more questions and I will be more than happy to help.

  13. I stumbled across your website while looking for answers to a question that somewhat baffles me about DNA test. I am writing in the hope that you can clarify something for me or perhaps point me in the right direction towards finding an answer.

    Essentially, I met and lived with a wonderful woman 28 years ago. She left quite suddenly and I later discovered that she was pregnant. I looked for her and the child for nearly 27 years. Several months ago, I found them. She had a son. She initially told me that he was not mine but the three of us agreed to get a DNA test for paternity. Two days before we got the result, she told me that she had lied to me and the child was mine and that she lied because she was married and her husband didnt know but that since we had done the test it was going to come out anyway.

    On a Tuesday night the DNA testing lab in San Antonio told me verbally (i understand that they are not supposed to) that the test showed that he was my son.

    The next day (Wednesday) the lab called me and told me they were having difficulty extracting my DNA from from swab that was provided to them by Quest Laboratories in Pittsburgh. Two swabs were provided to them and the kit was sent from San Antonio to Pittsburgh and back to San Antonio via fed ex. They also told me that had a “mutant finding” which was most likely because they could not get enough of my DNA. They also said that they were going to run the test again that night.

    The following morning at 9am, they provided me with a computerized output that showed I was not the father. Sounds all very Jerry Springerish, but I assure you this is how it happened.

    My question to you is does sound viable? is it possible to go from a verbal positive to a paper negative without some questionable act having occurred somewhere during the process?

    On a further note, the mother believes wholeheartedly that the results are wrong. Even though she is still married to the man who raised the child. They are all still a family and therefore have no basis or agenda to lie and tell me he is mine.

    Based on what I’ve said, can you offer any insight to me?

    • Hi Patrick,

      In the IDENTIGENE lab, results can only come back as one of the following: Yes(not excluded), No (excluded) or Inconclusive. Inconclusive means that no conclusion can be reached regarding your test, due to one or more possible reasons.

      We apologize, but because you tested with another company, we are unable to help you interpret your results. Have you tried contacting the lab/s who processed and tested your samples? They may be able to give further details on what happened or clarify your testing situation. It is important that you test with an accredited lab so that you are sure your results are accurate. As an highly accredited lab, we would be happy to help you with testing. Please call our client support line at 888-404-4363 if you would like to set up a paternity test. Thank you!

  14. I know I slept with 2 men , they both came back not the father …I was around 98% sure it was one and no then the other and no …ok REALLY ???? now the thing is the one I really was sure , well his parents are first cousins …. can that compromise the DNA test ???? oh please help me because nothing I mean nothing is making sense right now !!!!!!

    • Thank you for your question. Having a first cousin relationship will not compromise the DNA paternity test, as each person’s DNA profile is different, with the exception of identical twins. Our first question in a situation like yours is whether or not you witnessed the alleged fathers swab themselves and the child. Did you see them seal the envelope and did you take the envelope to the post office yourself immediately after the collection? Our test analyzes the DNA provided by the participants. A home DNA test relies on each participant to provide their DNA. It also trusts that once the swabs are enclosed in the mailing envelope, they are not tampered with by any other party. Our best advice is to contact us and to arrange for a legal collection at 1-888-404-4363. During a legal collection, an IDENTIGENE collector verifies identities of participants, witnesses the swabbing and mails the specimens to the labortory, this eliminates any chance of participant fraud or dishonesty.
      If you have any other questions or concerns, we would be happy to assist you. Please contact our client support staff at 1-888-404-4363. Thanks!

  15. The allies showed 11 out of 15 matched showing a 0.00 percent chance of my son being my husbands…..but im not in denial something happened here something must have because he was my ONLY sexual partner…..Im not in denial im serious. My other son showed up 99.999% I dont understand….So we just sent another test in this time I swabbed my mouth as well……what could be happening?

    • Michelle,

      Have you contacted our client support staff at 1-888-404-4363? They are open 9 a.m. to 8 p.m. EST M-F. Our recommendation would be to make sure that you follow the instructions carefully, witness the swabbing of each participant and follow the swabs to the mailing facility to ensure honesty. After you have done this, you can feel certain the results will yield an accurate answer. Social Media (DNA Testing Blog Staff) does not have access to your results. We recommend calling client support to discuss your case further. Thank you!

  16. Question: If during the DNA collection process your son was tested when in fact it should have been collected from your daughter, would that in anyway change the results of the test????

    • Dear Just Wondering,
      Are you trying to find out the paternity of your daughter? If so, yes, we need the daughter’s DNA to compare with the alleged father’s DNA. Also, whoever is listed on the specimen envelope should be who is swabbed. IDENTIGENE trusts each participant is who they say they are when we run the test. If you have further questions, please call client support at 888-404-4363. Thank you.

  17. When doing a dna test. Is it allowed for the father to do the test before the date set prior to the dna testing date.

    • Amy,
      Are you referring to a legal collection from IDENTIGENE or your state government? For a peace of mind test by IDENTIGENE, there aren’t any set dates. It is a home convenience DNA Paternity Test. If we set up a legal collection, IDENTIGENE will arrange collection times/places for each of the participants and a collector will witness the tests. Please let us know so that we can try and help you. You can call us at 1-888-404-4363

  18. I believe that my friends identigene test was messed up in the lab process because it is 100% impossible for him ot be the father of a child that is not his. when you sent back your results it said that he was the father which studies shown have found to be biologically untrue due to the information given. here is what happened.
    intercourse took place once mid february with protection and the mother told him that she was pregnant after that he had nothing to do with her. it turned out that she was actually pregnant in june when he was no where near or around her. and she just had the baby in april. how could he possibly be the father like your results said if he has proof that nowhere near here in june and he has proof of it by family and friends? was the test misdone or did something go wrong in the lab? also his test results were turned back in extrememly late saying he was the father which is false because during the time of pregnancy he was not near her and she pretended to be pregnant in februaury to break him and his girlfriend up and when she really did get pregnant she strung him along because he was already involved in her lies. could you resubmit for free? because those results were completely off and makes others not want to deal with the product at all due to falsitivity.

  19. i believe that my friends identigene test was messed up in the lab process because it is 100% impossible for him ot be the father of a child that is not his. when you sent back your results it said that he was the father which studies shown have found to be biologically untrue due to the information given. here is the story;

    • Dear Concerned,
      I am sorry that you are doubting your friend’s test results. This case seems to come down to the two people intimately involved as well as trust and honesty. We stand by our results being 100% accurate. Your friend is welcome to test with another DNA paternity test company but we would recommend upgrading the test to a legal collection where the identification is verified as well as the entire process is witnessed and the collector mails the samples to the lab. This takes all question out of the testing. Identigene can perform a legal collection if your friend and the mother agree to a retest. However, Identigene will not perform the test for free. They would have to pay the legal collection and lab processing fees.

      For a test to come back positive, it means that the DNA of the alleged father matched the child’s DNA. If the test from start to finish (opening the kit to mailing the envelopes) wasn’t witnessed by the alleged father, it is possible that the mother knowingly swabbed the true biological father and switched the swabs at the time of sealing the envelope. There have been cases of paternity fraud where mothers “pick” who is they want to be the child’s father, regardless of DNA, and manipulate the samples for the peace of mind test.

      The only way to confirm would be to complete a legal DNA test. This takes all possibilities of fraud out of the equation because a collector conducts the testing and mails the samples to our lab.

      Best to you and thank you for contacting Identigene.

  20. hi ive dun a dna test with u b4 n the test came backhat the lad we tested wasnt my childs father! but my childs the image of him youd think they wer twins when they are together. how is this possible?

    • LouLou, I would suggest you contact Identigene client support at 1-888-404-4363 to speak with a client support representative. Identigene stands by their results and if they concluded he was not the father, than the DNA submitted didn’t match at enough places for us to determine biological paternity. If you think that there is a possibility of participant dishonesty, meaning the alleged father didn’t really swab himself but swabbed someone else to alter the outcome of the DNA paternity test, then Identigene would recommend a legal collection where the collection is witnessed and the identities of each participant are verified and documented. Please let us know if you have additional questions. Thank you.

  21. if i done a dna test with my uncle which is my grandpas brother could it come back a false positive because we are kin.. there is a possibilty he is my dad?

    • Barbara,
      I would advise that you contact client support at 888-404-4363 to discuss your case #. If I understand your comment, you are asking if your great-uncle could be your dad. The paternity test would determine whether or not the alleged father swabbed is your biological father based on submitted DNA. Because he is your grandpa’s brother shouldn’t matter. Again, I would advise you speak with client support. Thank you for contacting Identigene.

  22. My question is if i sent both mine and the childs dna samples off together, is there still away my samples could’ve been switched by accident?

    • Dear Dewayne,
      Did you follow package instructions and place each participants swabs in their own envelope and seal them? Usually when a participant swabs him/herself, they don’t move on to the next participant’s swabbing until one is entirely complete (3 swabs placed in one collection envelope, sealed and participant information complete on the front side of the envelope). This omits the chance for user error. If you have concerns about your collection process, please contact our client support staff at 888-404-4363. Best and thanks for contacting Identigene.

  23. Can having lots of dental work, and shaving of the bone of where back tooth extracted,and having the gum packed effect the result of a dna swab test.

    • Dear Angela,
      No. Dental work will not affect DNA. The buccal swab included in our kit takes cells from a person’s cheek. DNA is your unique genetic make-up. Dental work will not alter your blood. Hope this helps.

  24. Well I took this test and it stated my son’s father wasn’t the father when I was only wit home and I had my boyfriend tak a text as well bc him n I wasn’t together no were around the time I got pregnant cld it b possible if my boyfriend mother switch swabs out wit my sons swab bc my baby daddy n I were devistated bc he n I new we weren’t with anyone else during thur time I got pregnant please help me

    • Renae,
      If the test wasn’t witnessed by you or a third party, it is possible that fraud could be involved. We would recommend that you retest with a legal collection, one that will be upheld in court and witnessed. You can arrange for a test through our client support office. The number is 888-404-4363. They will work out a processing charge for you, taking in consideration you have already done a home test with us.

  25. Hello my aunt is trying to do a paternity test with my son. Is that even legal without parent consent?

  26. If you take a dna home kit test, and you have a son, but his dna came back as female. Is it possible that the test was tampered with?

    • Hi Tiona,
      I am forwarding your question to client support. I will get back with you shortly. Thanks.

    • Dear Tiona,
      Yes, it is possible, but it would happen before it arrived at the lab. A person could try and alter the results by swabbing someone of another gender instead of who was identified on the paperwork. When this happens we place the case on hold and recollect samples.

  27. i have taken my ex partner to court to find out if her son is my child her bf has been given permission by the courts to take on responsibility for the dna testing and samples the court suggested a reputable company they use my ex and her partner asked to use whozthedaddy.com im worried if they use a home testing kit the could tamper with the samples either mine or my potential sons by using someone elses is this possible and would it get found out i would appreciate an answer as soon as possible thankyou

    • Dear Mark,
      Since the results need to be court admissible, I would recommend using the Identigene home DNA paternity test found at CVS, Walgreens, DuaneReade, USA Drug, RiteAid and Walmart. Please call our customer service department to arrange for a legal collection so that the samples are witnessed, proper identity is confirmed, chain of custody forms are completed and the collector mails the samples. You are valid in worrying about samples being tampered with if the collection is not witnessed by a third party. If you have questions, please contact client support at 888-404-4363. Thanks.

  28. OK I TOOK A PATERNITY TEST WITH 3 OF MY SIBLINGS AT THE SAME TIME AND MY TEST CAME BACK THAT I WASN’T HIS CHILD BUT EVERYWHERE I GO SOMEONE SAYS THAT I LOOK JUST LIKE HIM AND I HAVE A FEELING THAT MY TEST GOT SWITCHED WITH ONE OF MY SIBLINGS THAT LOOKS NOTHING LIKE MY FATHER IS IT POSSIBLE THAT THE LAB SWITCHED OUR TEST ON ACCIDENT

    • Hi Brea,
      Our laboratory follows very strict guidelines set by our accreditations that prevent this from happening. I would recommend if you do not trust the results to have a separate paternity test done with just the alleged father and yourself to ease your uncertainty.

  29. Is it possible that you let another person take the paternity test with her and she was bound to prove he wasnt the father and switched the babies swabs with the mothers is there any way you guys are able to tell?

    • Jenna, the only way to know a test is 100% honest, is to have Identigene arrange for a 3rd party witness. That person handles the chain of custody paperwork, verifies identification, witnesses the swabs and handles the mailing. We call this a “legal collection”. This type of DNA paternity testing is court admissible. If someone purchases our kit and completes a “peace of mind” test (no formal, appointed witness by Identigene) we can only trust what is documented by the legal parent. We have to trust that each person swabbing is who they say they are and they do not try and manipulate the test in any way. Our test only examines DNA. We wouldn’t be able to tell if “John Doe” swabbed his neighbor but signed the paperwork and said it was his DNA. Same thing with the child. Again, our “Peace of Mind” test (not witnessed) relies on the honesty of the testing participants. A witnessed collection and mailing is the only way someone can be 100% sure that the testing participants are who they say they are and the results weren’t tampered with after swabbing.

  30. is it possible that if a guy wanted to do a DNA test for father and son and instead sent 2 full blood brothers in instead of alleged father and son it would come back a match as father and son instead of brothers?

    • Dear Wondering,
      No. The brothers would not match as a paternity. We only calculate for paternity. We do not calculate for any other biological relationship.

  31. I def want a retest now that i know that my ex boyfriends mother took the swab i swabbed my son with & swabbed his spoon he was eating off of ……. she payed for the test so its in her name but i was wondering how i could do a retest if she doesnt agree to do one. the alleged father has agreed to do it over & is allowing me to do mine & my sons swab with my relatives. so is there any way i can have our retest swabs sent to my house & have the allegeds dads sent to his house?? how do i go about this? we dont want to do a legal test collection. i have agreed to video tape the whole thing & put it into a city mail box……i just refuse to bring my son around them until we retest && get the results back.

    • Dear Feelingbetrayed,
      First, swabbing the spoon should not compromise the DNA on your son’s swab, even if food got on the swab. The swabs are designed to grab DNA from the cheek. If you swabbed your son’s cheek, the DNA from his cheek would remain on the swab despite contact with food from a spoon. Have you received a results statement yet from IDENTIGENE? Did it come back with a determination of paternity? Excluded or Not Excluded? Please contact client support with your particular case number. They will be able to look up your case number, results statement and give advice for next steps. The number is 888-404-GENE. I will go ahead and send your email address to them to contact you via email as well.

      Thank you for contacting IDENTIGENE.

  32. My sons ex-girlfriend does not want him to be the father but agreed to do the test. She claimed she swabed the baby when we were out of the room. I think she swabed herself after she refused to do it again in front of us. I lightly swabed the spoon the baby ate from hoping to get some dna. Possible, or wasting my money?

    • Hi Suzie,
      If this is an IDENTIGENE test, our test requires cheek cells. The kit contains three sets of three swabs. Our lab will be able to detect a double profile (mom’s DNA on same swab as baby). This would result in an inconclusive result and require a retest. I would recommend contacting IDENTIGENE before sending in the swabs and upgrading to a legal test collection. This will increase the cost, however, given your situation of possible paternity fraud, it would be worth it. IDENTIGENE can arrange for a collector to witness the testing. This way, everyone knows the swabs are honest. The collector will also mail the swabs so that noone can tamper with the swabs. Please visit http://www.dnatesting.com/dna-testing/legal-paternity-testing.php for more information on legal collection.

  33. i recently took this test to see if someone was my father. the test came back that he is not. is there anyway this could be wrong or what if he swabbed him mouth incorrectly?

    • If the person who swabbed themselves really swabbed themself, then you can feel confident about your results. Swabbing incorrectly (eating, drinking before or not swabbing long enough) would produce inconclusive results and we would alert the customer. Since you received a result, we were able to grab enough DNA off of the swab for the test.

  34. Hello,
    I recently went through a dna test with my daughter and the alleged father, the results came back close relative match, I know he’s the only one I’d slept with??? So could this mean he sent in a brother or cousin???

  35. I want to do a dna test on my son but im worried I will get the wrong results b/c the 2possible fathers are brothers but I can only test 1brother. What can I do to get accurate results without paying alot of money? THANKS

    • Hi Krystal,
      You can still do a DNA Paternity Test unless the brothers are identical twins. Our recommendations would be for you, child, and alleged father to be tested. When you send in the paperwork for your test, please contact the lab (888-404-GENE) ahead of time and make sure they know the situation (two potential fathers that are brothers). The cost of the test is $30 at a major drugstrore and then an additional $129 lab processing fee. Our results are 100% accurate.

  36. There may be a possibility that my father isn’t my father but that his brother is. We are about to do a dna test what will the test result show if he is indeed my uncle instead of my father?

    • Hi Misty,
      Unless your dad’s brother is his identical twin, the DNA paternity test will determine whether or not he is your biological father. If he isn’t your father, you should test your uncle.

  37. i dont wont to pay for another test dont have the money

  38. does it matter if i drink something before the test was done and the gut that might be my dad brush his teeth after he ate?,cause he is not my dad and we look alot alike and his son we look like twins when we were babys

    • Hi Kimberly,
      Eating or drinking an hour before swabbing can contaminate the swabs. If that were to happen the lab would not have been able to extract a profile at all. Because they were able to get a profile this indicates there was not contamination and the DNA was just fine. Eating and drinking before swabbing will not change your DNA in any way.

  39. My spouse and daughter had dna test done.the mother and child went that morning and my husband went that afternoon.we are not sure what really happen that day.it came out to be my husband.does it matter if they test at different times

    • Hello Mary,

      No, it does not matter if they are tested at different times. If they were collected by a third party collector this ensures the samples that are sent to the laboratory are the samples from the correct participants. If they were not collected at a collection facility and collected their own samples and you are not confident with the results, I would recommend doing a legal paternity test which will include having the participants all collected by a third party collector. The collector will collect the samples, verify ID, and take photos in most cases. They ship the samples to the laboratory to establish a chain of custody.

      I hope this helps. Please let us know if you have any other questions.

  40. I got my Dna results and it excluded the accused man as the father. When I was looking at the dates our mouths were swabbed his date was incorrect…is that cause for concern

    • Michelle,
      Thank you for contacting us. Can you please specify what you mean when you say “the dates our mouths were swabbed his date was incorrect”? Was this a legal collection? Or did you or the alleged father fill out the collection envelopes and send in? You can always contact our customer service department at 888-404-GENE with questions.

  41. Today, my news came of my Avuncular DNA Test with my alleged bio-aunt. The problem I have is my bio-mother did not test with us and now I am left to ask would the test be more accurate if she had tested with us. I am unable to test the alleged father due to him being deceased…..nobody really explained this test to me accept at the lab they said it would be either 0 or 99% with my alleged aunt…I could DNA test a full brother per my bio-mother, or two alleged half sisters…can you bring some insight on this to me…I already made a costly investment and the results are only 15.3% with alleged Aunt. Should I have included my bio-mother for a more accurate result in this Avuncular DNA Test?

    • Hi Shauna,

      Including your biological mother when testing an avuncular would help with the tests conclusion. DNA testing is very accurate, its the probability of a biological relationship that can increase or decrease when including your mother in the testing. I would recommend contacting the laboratory that completed the testing to see if they can include your mother’s DNA and re-calculate for additional cost (Cheaper than starting over).

      With Avuncular testing it’s not likely to get a 99% probability of a biological relationship like you get with paternity testing. Also, you want to make sure the aunt/uncle you test with is a full sibling to the alleged father. Half siblings of the alleged father are a bit to distant to give a definitive answer.

      • I recently took a dna test n it came back o% but hes his twin also the place we went too seemed like they didn’t know what they were doing they only stabbed one cheek can u get enough dna with swabbing one cheek?

        • Hi Jessica,

          If you tested with IDENTIGENE, it is important that you notify us if there is more than one possible father that are closely related. In the case of twins, if they are identical, they will have the same DNA profiles, but if they are fraternal they will different but very similar DNA profiles. In answer to your second question, yes, swabbing one cheek will yield enough DNA to use for testing. It is not necessary to swab both cheeks. If you have more specific questions about your test and you tested with IDENTIGENE, please call us at 1-888-404-4363.
