Man taking paternity test

How do DNA samples for paternity testing become contaminated?

Paternity Testing

When samples for paternity testing are sent to the IDENTIGENE laboratory, the DNA carried within the cheek swabs could become contaminated a few different ways. How can you avoid this from happening? Here are a few tips. Paternity test DNA collection When you collect the DNA samples for a paternity test, there are a few rules you want to follow: First, don’t eat or drink, smoke, brush your teeth, etc. for at least one hour before doing the cheek swab collections. The food/drink or any other matter can mask the DNA making it unusable for paternity tests. Although re-collections are completed one time at no cost to you, it can take more time before you get your paternity test results. You don’t want to have to wait any longer than you have to…right? Collection of the DNA samples for the  paternity test Swabs may become contaminated by contact with anther person’s DNA, maybe by someone who is collecting the sample. This can happen by someone inadvertently handling the tips of the swab, or dropping the swab. According to Dr. Donna Housley, the IDENTIGENE  lab director, “Sometimes the swabs are contaminated because people mix up the envelopes and put swabs from 2 different people in the same envelope, this is quite common. Also if a person has ever had a bone marrow transplant or a recent blood transfusion the profile could come back contaminated because we see two profiles from one individual when we amplify the DNA.” When submitting DNA samples for paternity testing, avoid the original plastic packaging  

DNA Collection

Something else you want to avoid is placing the DNA collection swabs back into the plastic wrapper it originally arrived in. You want to place the samples directly into the paper envelope provided in the IDENTIGENE DNA collection kit. Keep in mind the collection envelopes may become wet because, unfortunately, saliva does affix itself to the cheek cells that are needed to extract the DNA. If this does happen, you will want to lay the sample envelope down on a clean counter and let them air dry at room temperature. Sometimes when wet sample envelopes are mailed, they rip and this could contaminate all of the samples, including samples of other participants. DNA sample collection to help make your paternity test easy Follow these tips and all of the other instructions included inside of the IDENTIGENE DNA collection kit and your samples will most likely arrive at our laboratory ready for paternity testing, and you will receive your paternity test results on time.

    I did a test through you guys back in 2008 and my test results was 99.6% and a combined parentage index of 2,816 and before it was sent my girlfriend let our son who was a slobbing 2 month oldput his wet hands on the sample, Is there any way the DNA test could have been given the wrong numbers, My oldest son was 4 yrs old and was the test subject but my 2 month old grab the swab with his slobbing wet hands, You think I need to redo that DNA test because my son is being hid for over 2 1/2 yrs and im paying 600+ in child support…

      If there were mixed profiles on the DNA samples the laboratory would have seen that. There would have been two sets of DNA. Because the profiles were clean (we know this because you were given a result) I would say they are accurate. However, if you are having doubts I would recommend having another test completed for verification.

  2. Carla says

    I did a paternity test through court and while doing this the person drop the swab before putting it in the mouth of the guy that might be the father. Could the swab get contaminated because I want to know how accurate is this DNA testing?

    • says

      If a sample is contaminated in anyway, the laboratory would not be able to extract a profile. This would mean the laboratory would need to recollect the sample. If a recollection was not required, this is a good indication that the sample was not contaminated and the lab was able to extract a good profile for comparison.

  3. liz says

    If my child and myself had drank a fruit punch drink before having DNA test will that contaminate the DNA test ?? As we were not told not to drink anything before testing, so we finished our drnks and enter the place for testing. Was not asked by tech if we had anything to eat or drink within the hour.

    • says

      HI Liz,

      If the laboratory was able to extract a profile that means the DNA was not contaminated in anyway. Anything you eat or drink will not change the DNA in any way. If anything it would “destroy” the DNA so a profile would not be found. If a DNA profile was extracted than the DNA was not contaminated. I hope this does help.

  4. Shelby says

    So my husband and my son took a paternity test, just for his peace of mind. I know for sure he is the father. But they used an online test with mouth swabs, and if he put his swabs in the envelope while they were still wet, could that mess up the results at all? Thanks.

    • says

      Hi Shelby,

      No, that will not hurt them at all. Worse case the swabs will touch to create a double profile. If that does happen we recollect at no charge to you! Feel free to contact our client support team any time to check on the status of your case to help put your mind at ease.

  5. Meesh says

    Hi Amber, if I brushed my teeth a hour before and me nd my baby father ate atleast 25 mins before our paternity test and my baby ate an hour before the test and our results came back negative becux 6 out of 7 paternity index did not have a percent but the other 3 read : 2.29 , 1.34 and 2.44 might we did something wrong at all? Oh and on 2 or 3 that paternity index him and his father had matched atleast one number together in all 3 could we have effected the test? Should we take another test through a different company to see?

    • says

      Hi Meesha,

      In order for the alleged father to be the biological father he must match each location. There may be a few loci matches, and that simply means those specific numbers at those specific locations are common among the population, it does not indicate a biological relationship. As far as eating or drinking before collecting the DNA, we do ask that you don’t do that for at least an hour before swabbing to help reduce the risk of food particles mixing in with sample. This is to reduce the risk of contamination. However, if their was an issue with that the lab would not have been able to get a profile at all and we would have asked you to recollect the samples. Food and other items will NOT change your DNA. Because the lab did get profiles this tells me the DNA was just fine. At this point I would recommend testing any other potential fathers to help determine the biological father.

  6. Meesh says

    I’m sorry I meant 6 out of 9 had no percent but 3 did have a percent . BUT… 3 out of the 6 that had no percent , him and his dad DID have atleast one match in all 3

  7. meesha says

    hi Amber ,

    ok im almost certain that my boyfriend is the father of my child and our results came back that he is not . But we ate and brushed our teeths a half hour prior to the testing and i was wondering if that could screw up the strength of the test i knw it doesnt change dna but can it be the reason y some markers wherent found and on some if the markers my boyfriend and my son did match a number but they didnt get any percent . i dont know what happened but do you think we should retake it at a different lab?

    • says

      Hi Meesha,

      I really hope my last response answered your question, however, if it did not please feel free to contact client support at 888-404-4363. We would be happy to answer any further questions.

  8. scott says

    My wife and I ran the test awhile back and it came back that I was definitely the father. But as I looked back on the whole thing, it bothers me that my wife waited a few days before mailing it. So I wondered if she didnt perhaps buy another test kit and allow the real father to use a different envelope and submit it with the childs swabs, and throw away mine.

    My question is, do your test kits have all the envelopes/swabs marked the same within a kit? If you do, my mind would be put to rest.

    Thanks!

    • says

      Hi Scott,

      If she was to do something like that, there is no way to tell. You can contact our client support team and request a copy of your own signed envelope to see what was mailed in. When something like this happens I recommend doing a legally collected DNA test. This is where all participants are collected at a collection facility and the collector sends us the samples to establish a chain of custody. This will ensure they are not tampered with by any of the participants.

  9. Melissa says

    Hello I know for a fact my sons dad is his dad..but my sons family on his dad side did a in home test through universal genectics and they sai hed the results came back that he is excluded from being the father. They only matched 5 out of 16 markers and o% pi ..how can that happen if he is the only Guy i was with..

    • says

      HI Melissa,

      You would want to determine if it was a personally collected DNA test. If so, they are not court admissible because the lab can not verify whose sample was actually submitted. If you are sure he is the only possibility I would recommend that you suggest another test with your samples submitted as well, where you witness the collection yourself, or you may want to consider a legal paternity test. That is where all participants are collected at a facility and the collector submits the samples to the lab for testing. This will ensure that the samples were not tampered with by any of the participants, and they also verify ID to determine whose samples are actually being submitted. I really hope this helps and if you have any other questions please let us know.

  10. Jeri says

    Hello

    After collecting the samples from my fiance and his son I noticed small wet stains on both of the envelopes. We made sure we collected the samples in the morning before they ate, drank or brushed their teeth but now I’m concerned the qtips can be contaminated…? Also, my husband is 100% Jamaican and his son’s mother is African-American; will the results verify if the son is also of Jamaican descent?

    • says

      Hi Jeri,

      Because saliva comes along with the cheek cells when using the buccal swabs, the envelope may get damp, and that is just fine. We recommend letting them dry at room temperature.

      When calculating probability of paternity we do take into consideration the ethnicity of the alleged father and the mother, however, we do not ask for ethnicity of the child. The Child’s ethnicity will not affect the results of the paternity test.

  11. Jeri says

    Hi Amber…sorry if I didn’t explain very well….the two wet envelopes were laying on top of each other. Will this effect the results and possibly show him as the father if he is not since the two wet swabs possibly came in contact with each other thru the envelopes? Also the mother was not tested…just the father and son. Sorry for the confusion..

    • says

      Hi Jeri,

      The DNA profiles should be just fine. IF they came in contact with each other the profiles would most likely come out with either two profiles, or identical profiles. In either case we would recollect samples at no charge!

  12. Bren says

    Hi Amber,

    I have recently taken my 2 month old baby for DNA testing with her father and results came back as him not being the father. My baby had a blood transfusion when she was born but dont recall what it was for. Could that have any effect of the results? I know he was the only one. What can I do? Thank you

    • says

      Hi Bren,

      It is rare that a blood transfusion would affect the DNA profile of your child. A bone marrow transplant is much more likely to affect the DNA profile obtained. In the rare instance that a transfusion does affect the results, it would usually result in what would appear to the laboratory as a contaminated profile and a recollection would be requested. It is unlikely to see a completely different profile. Also if the mother is tested along with the child, as is always recommended, it would be apparent if the incorrect profile for the child was obtained. We would always request the mother’s sample in such a case.

  13. Bren says

    Amber,

    Thank you for your response. In fact my daughter had a blood transfusion for really low platelets. But her father has a son and my baby nd his have same features. I know its his baby but the results thru us off big time. What should I do? Call the Determigene for another test nd do we have to pay again? When we ordered the test we werent asked about blood transfusion or bone marrow transplant until the day of thr testing

    • says

      If you want peace of mind with another test I would recommend it. Keep in mind the blood transfusion would most likely not affect the results, however, sometimes peace of mind goes a long way. I would recommend waiting about 6 months from the time of the transfusion to take the test to really put your mind at ease. You will most likely need to pay for another test, however, you can contact the laboratory that completed the testing to see what they can do for you.

  14. Debbie says

    Hi Amber,

    We had a paternity test done at a hospital. My son was very fidgety and I had to hold his mouth open and while the lady was swabbing his mouth the swab touched my hand.The lady looked at me and then just kept talking so I didn’t think to say anything wish I would have now. The test came back that the guy I believed to be the father was not but when I calculate the dates he was the only guy I was with at that time. Is it possible that my hand touching the swab could of contaminated it?

    • KD says

      Dear Debbie,
      We can only speak for the Identigene test and our laboratory. If you take the Identigene test, we recommend you test mother, child and alleged father. We also ask for three swabs from each person. We do this because of the situation you described. If the DNA sample from your child’s cheek swab wasn’t consistent on the three swabs, we would have your DNA to compare it to or if a double profile was present (your DNA and another’s DNA on one swab) the lab would recollect at that point, just to be safe. If ever Identigene suspects contamination or doesn’t get enough DNA for our test, we would contact the customer and ask to recollect at no additional charge. You can purchase our kit at any major drugstore.

  15. ER says

    My daughter and her alleged father was tested it was determine he wasn’t the father I strongly feel he is because he was the only one I was involve with.The DNA specialist tested her with a candy could that have affect the test should I have a better to have a bllod test.

    • KD says

      ER,
      We can only speak for the Identigene test. We recommend a cheek swab from each party – mom, child and alleged father. The inside of the cheek’s DNA is the same as blood DNA. I would recommend you retest using cheek DNA. Our kit can be found at major drugstores.

  16. Samantha says

    I just got the results to my DNA test & was wondering what if on accident I put NY daughters swabs in my envelope and mine in hers would that effect the results ? Im pretty sure I didnt do that but just in case I was curious. And another thing I was wondering is how do you determine if the gene is mutated I think was the word?

    • says

      Hi Samantha,

      If the results are “not excluded” meaning he is considered to be the biological father then they were certainly not swapped. This is because the child and alleged father match and the mother and alleged father would not. On any exclusions we always check for a mother/child swap to confirm findings. As for mutations If there is only a single mismatch and it is off by only a single repeat unit (allele number) between the child and AF, and the remaining markers are consistent with paternity, we say that the locus is consistent with a mutation event.

  17. Kaye says

    I mailed off the DNA swabs last week, as I was getting the package ready I noticed that the alleged father swabbed the child in question on 9/11/11. He was swabbed the day I mailed it 2/9/12. (We lost the box and found it when we moved.) Also, I noticed that he placed the child’s swabs back in the original plastic wrap. So, my question is will the test be a total flop, since the sample is 5 months old and then placed in plastic? Clearly, he did not read the directions. I did, therefore, his sample was good.

    • says

      Hello Kaye,

      Once the samples are taken they are good for about 6 months. We don’t want the samples placed back into the original plastic, but if they were kept at room temperature we may be able to get a good profile. You can choose to send them in or purchase a new kit. If you do submit the samples and we are not able to extract a good profile we will ask for a recollection at no charge to you one time. We will even send you new supplies. This will keep you from having to purchase a new kit.
      I hope this answers your question, please contact us again if you have any other questions.

  18. Ali says

    Hi my husband and my daughter took a swab DNA test. Although my husband did not eat drink or smoke for an hour before the test some food from his teeth got on the test swab. Will that matter when I get my results back?

    • KD says

      Hi Ali,
      Eating or drinking can contaminate the swabs. If that were to happen the lab would not have been able to extract a profile at all and would contact you for a retest. If you haven’t been contacted, this indicates there was not contamination and the DNA was just fine.

  19. kim says

    Hello, I conceived around may 19th and slept with my partner twice around the time from 20th onwards but chheated with another man in this same time. We carried out two paternity tests which both came back negative. My partner done the swabs infront oof me so unlikey they were tampered with but I highyly doubt the second company, was a random company online who sent me a pack of swabs aand a pack to the alleged father. I sent my swabs which they received 2 days later but didn’t receive the males. So they told me for the test to be carried out either me or the male had to pay 30 for more swabs to be sent out but I suggested I would just send him my spare swabs ( cause the packs are pre made so I had the alleged fathers left over ) they went along with it and I let them know I had sent the swabs to the alleged fatherr special delivery and the company would receive them within 3 days. 2 days later they emailed saying they received the first set the male had sent as he hadn’t even had a chance to send the second sample. The first were sent first class and took 12 days to get there, aare they messing us about and not even a lagit company? Something has to have went wrong as there is no one else, I’m at my whits end and driving me mad reading all this info online. Please help!

    • KD says

      Dear Kim,
      It does sound like you are having a hard time. I would suggest you call the company you used for your DNA paternity test and get some answers. We can only speak for Identigene. You can call our customer service department if you are interested in retesting using the Identigene test. 888-404-GENE

  20. chae says

    i had my baby tested on march 20 we recieved the results of negative on march 26..my question to you is if my 6 week old baby was drinking lactose sensitive formula mixed with barley flakes and the bottle taken out and the swabs taken a second later. could that possibly contaminate the test and give a false result….

    • KD says

      Hi Chae,
      Food can contaminate the buccal swab and block DNA from being extracted by our laboratory, however, if we were able to pull DNA (we were in your case since you received a results statement) from the swab then we will provide results. If the food would have truly contaminated the swab, Identigene wouldv’e contacted you and requested you to reswab at no additional charge. Food DOES NOT change DNA. It can only prohibit us from getting it off the swab.

  21. lil lady says

    My sex partner and I did a home testing kit,he just collected my baby’s saliva and the results came back negative,ive been wit him since April 24,2011 and found out I was prego June 28,2011,could he b the father

    • KD says

      Hi Lil Lady,
      I’m sorry but I do not understand your question. I’m assuming there is more than one alleged father since you took a paternity test. When you say it came back negative, are you referring to the DNA paternity test results? Did you use an Identigene test? I would call our client support to talk specifically about your results statement. They can be reached at 888-404-GENE.

  22. doubtful says

    Is it possible that an alleged father who is also swabbing himself and the child could contaminate the child’s swan, resulting in false results?

    • KD says

      Hi Doubtful,
      It is always possible for someone to swab someone other than themselves or the child involved if they are not being supervised during a “peace of mind” DNA paternity test. If you have doubts, I would highly recommend doing a legal collection. Identigene can set this up. Please call 888-404-GENE. In a legal collection, Identigene sets up a collector to witness the tests and mails the samples into the lab. This process still utilizes the same kit sold in drugstores.

      • Wondering says

        Hi My Husband had this problem as well with a peace of mind kit 5 years ago. He swabbed the child and So did the mother. The DNA came back positive 99.9999354%. Wondering if there is a possibility of contamination or wrong result? Having doubts and was wondering if he gets a court based test it would change at all?

        • KD says

          Dear Wondering,
          Thanks for your question. There is a possibility that the samples could be contaminated with food or drink, but we are able to detect any contamination once the testing begins. If this happens, we would stop testing and contact you about re-collecting the samples. It is highly unlikely that anyone else could be the child’s father with the probability of relationship result as 99.99%, as this is the highest result possible. Having a legal or court admissible test will not change the results as the only difference between our peace of mind test and legal test is that a collector is present to handle the paperwork, witness the collection and mail the test to our laboratory. If, however, you have any doubts about where the samples came from (whose samples they are), it would be best to witness the sample collection as well as accompanying the samples directly to the mailing facility. IDENTIGENE provides the most accurate testing available on the market today. We have worked extremely hard to put measures in place that prevent any mistake from being made throughout the entire DNA testing process from beginning to end. If you have any other questions feel free to contact us at 1-888-404-(GENE) 4363.

  23. concerned dad says

    i recently did a dna test with my ex girlfriend. she refused to do the dna test around me so i let her do it at her house. she swabbed herself and the baby but i have doubts that she swabbed herself twice instead of swabbing her son. will i be able to tell if she did this?

  24. mothers love says

    i think my daughter swab her son and touch the fathers swabs together. the test came out he was the father could this be wrong

    • KD says

      Dear Mother’s Love,
      If IDENTIGENE supplied “excluded” or “not excluded” on the test results, they pulled consistant DNA from each party (mom, child, alleged father) and were able to conclude a result. If there was a double profile on a swab (dad and child’s DNA both on the same swab), they would have tried the other swabs or contacted the involved parties for a retest. Now, if the mother swabbed someone other than the alleged father on all three swabs, or switched the swabs, our test wouldn’t be able to detect this. Our “peace of mind” testing relies on all parties being honest and who they say they are. If you are still doubtful, you could always call IDENTIGENE and set up a “legal collection” where we hire a collector to witness the swabbing and mail in the swabs, as well as collect proper identification and paperwork, which eliminates the chances for customer paternity fraud.

  25. Destiny says

    I took the est a month ago an twenty minutes before we took it we ate mc donalds m daughter even ate some. Im prety sure he is the father an my results came out wrong??? I would like some retesting swabbs if that is possible.

    • KD says

      Destiny,
      Please contact customer service about your test. Did you get a results statement? Did it provide you with an “excluded” or “not excluded” result? Eating before the test can’t change the DNA it can only block it from getting on the swab. I will pass along your email address to client support. I would advise contacting them to discuss your test results. Thank you! 888-404-4363

  26. Quinetta n says

    i took a test with you all a month ago my daughter was only a few weeks old. Would that have anything to do with the outcome of the results? Also can you explain the matching to me so I can understand how it work. How accurate are the results ?

    • KD says

      Dear Quinetta. Please contact our customer service department, 888-404-4363, with your case # and they can go over your results statement. Your child’s age should not have any effect on the outcome of the test. We compare the biological father’s DNA with her DNA to get the probability of paternity.

  27. jay says

    I put the dna swabs back in the plastic bags and then the envelope for mailing. Will this effect the accuracy of the test?

    • KD says

      Hi Jay,
      It will not effect the accuracy. If anything at all it may contaminate the DNA which means we can not get a profile and would need to recollect. If a profile is obtained then the DNA was not contaminated and was a good sample. Thank you for contacting us with your question.

  28. kim says

    Typically how long does it take for you to receive the samples once they are mailed because its been five days and i mailed it from tx to identigene?

    • KD says

      Dear Kim, I would allow 4 business days for receipt to Salt Lake City, Utah if you used the envelope included in the kit. When did you mail the samples? Did you mail it on Friday, Dec. 14?

  29. JJordan says

    I was wondering if my child’s cheek was swabbed for less than the 20 seconds will that affect the results. Also will there be a delay due to the holiday season? I sent the swabs on Dec 26th from CA.

    • KD says

      Hello JJordan,
      If our laboratory cannot pull DNA from the three swabs used on your child, they will contact you. Our laboratory was closed on Jan. 1 but open the other days (except weekends). Depending on your mailing method (express, overnight, priority or standard mail) will determine how soon your results will be available. Once they reach us, it is only 2 business days for lab turnaround. Please contact us at 888-404-4363 if you have any questions.

  30. tracie cardwell says

    My son had a DNA test last year when the child was 8 months but he had smoked before he went in could that affect the results he did have six matches and everyone says she’s the double of my youngest son .

    • KD says

      Dear Tracie,
      No, smoking will not affect his DNA. If you are still in doubt, you could have him participate in a second DNA test to confirm the results.

  31. Julie says

    Hi, I expect strongly that my daughter is not my biological daughter. I ordered a swab test online and had one sent to my ex, the first test she claims she did not receive.. She received the second and I came back that my daughter and my dna was a match! But u know my ex is still in contact with the man I think is the father.. I think she may have filled out my details but swabbed his mouth! Could it be possible the dna got mixed in the lab if they were both labelled with my name?

    • KD says

      Dear Julie,
      If the test wasn’t witnessed, a DNA laboratory can only assume the participants are honest. If you have questions, you should consider retesting with a legal collection, where the swabbing is witnessed and the collector mails the samples to the lab. This removes the chance for dishonesty.

    • KD says

      Carlos,
      No, if the cheek was swabbed according to package instructions, our laboratory should be able to grab DNA from the 3 buccal swabs. Thank you. Any additional questions, please contact client support at 888-404-4363. Best to you.

  33. Deedy says

    I know who my daughter’s father is b/c I wasn’t sexually active w/ anyone, but him the time of my conception & prior to conceiving my daughter I wasn’t sexually activefor 7 months. However my daughter’s father have doubts b/c we live in 2 different states. He had me purchase an identegene paternity testing kit from walgreens & swab my mouth & my daughter’s mouth & then send it thru the mail to his him. We did this 2 days ago. When he receive the kit he’s suppose to swab himself& send it in
    I wanted to know if this would effect our results b/c we swabbed at different times?
    I also want to know if my daughter sucking a pacifier would contaminate her swabs? My daughter is only 3weeks old & she suck a pacifier.
    Nnn
    Another questio

    • KD says

      Dear Deedy,
      Thank you for contacting Identigene. Swabbing at different times won’t effect the results, however, do you have any measures in place that will ensure that the father swabs himself and not another person? Since you aren’t there to witness the collection, we would recommend you have someone that you trust witness the swabbing and mailing.

      Your daughter sucking a pacifier will not affect the DNA. Hope this helps. Best!

  34. shunikia brown says

    Hi I Recently Took a at Home Dna Test the results came back in.said my son match 20 out of 24 of the boy alleles but it still said he wasnt the father. can you explain to me whats going on? im so confused

    • KD says

      Shunikia,
      It just means that the DNA had 20 matches. A child inherits genes from the mother and the father and if the father was the biological father, the child and father would match at each allele. According to genetics, a child MUST have one matching number to the father in each “locus” or allele. In some cases, there are natural mutations where the child has a slightly higher or lower value than the father but these are rare. Each Marker location shows 2 alleles.

      Everyone receives one number from their biological mother and one number from their biological father. These markers are analyzed to verify matches between the alleged father and the child. If the markers between the alleged father and child match they are given a Parentage Index number that indicates how common that marker is among the population. If the marker is rare the number will be higher, if the marker is common the number will be lower. These numbers calculate to give the probability of paternity. The probability of paternity for inclusions must be higher than 99%. The probability of paternity for exclusions will show as 0%.

      If you are still confused, please call our client support staff and they can talk you through it. The number is 1-888-404-4363. Thank you.

  35. tammie mccann says

    My question is: If swab DNA test was done. And child was not swabbed til 7monthslater. They keep fathers DNA for that long.. Would test be accurate or not…. Heard can keep only 6months.

    • KD says

      Tammie,
      We recommend sending in all the participants swabs before 6 months, but if a person hasn’t sent in the samples, we ask they still send in the specimens associated with the test and our lab will attempt to run the test as normal. If for some reason they cannot pull DNA from any of the swabs, they will contact the customer for a retest and we will send additional swabs. Hope that answers your question. If you want to talk with client support, please feel free to contact them at 1-888-404-4363. Thank you.

  36. Margaret says

    Hi… I was wondering if swabs can be contaminated if a person travels from one country to another does the testing then puts the swabs in the envelopes , drives back and sends the swabs by mail? For example: going to and from mexico to the united states? And how long does it take for results because the person the did the testing said it took her 2weeks to get the results.

    • KD says

      Dear Margaret,
      First, no traveling will not change DNA. Second, results can be delayed for several reasons. The main reason is mail method (choosing to use our postage paid envelope will take longer than sending overnight, two-day or priority mail). Once we receive the swabs, it usually takes 2 business days to process results. This can also be delayed if the paperwork is incomplete or filled out incorrectly; the samples are bad and we need to run the second or third swab for a participant; the mother doesn’t swab and the results are inconclusive and we have to request the mother’s DNA sample. Hope this helps. Thanks for contacting Identigene.

  37. michelle bond says

    I have a question how can it be possible for me and my son to take a paternity test while the absent dad was in jail but durning that time he nevr took at test he told me that but the result came back he was the father how is that possible .

    • KD says

      Michelle,
      I apologize but I am not clear on the situation. For a paternity test, Identigene requires the alleged father and child to swab. The mother is recommended. Unless we had a swab from the alleged father, Identigene would not be able to complete a DNA Paternity Test. Please contact client support if you have additional questions. 1-888-404-4363 M-F 8 a.m. to 9 p.m. ET. Thank you.

  38. daniela says

    My son looks so much like the father when he was a baby we did a dna test and it end up been negative so my queation is how can someone look so much as someone and not be it

    • KD says

      Daniela,
      Physical resemblances are a matter of opinion. For example, “You look just like your mother” might be the opinion of one family member and then another would disagree and say, “No, she looks just like her father.” The opposite often occurs when parents have children that look nothing like them. This is where the comments come from that reference the “milk man” or “switched at birth”. DNA testing is the only way to confirm biological relationships accurately. If you doubt the paternity test results, you can always retest with another company or purchase a legal collection which will require an assigned third party to witness and mail the swabs. Thanks for contacting Identigene.

  42. Daren says

    Hi. I am looking to test the alleged father of my adopted son. I have one, 15 month old buccal swab which has been stored in a vial at room temperature, but he dropped another buccal swab off today for good measure. My mother threw one away and kept the other, without double checking which one was which, so now I do not know how old the buccal swab is – it could be 15 months old, or it could be one day old. I see in the kit paperwork it asks the date of collection, of which i now do not know. Will it matter if I just right down the date of the more current one? Will the lab need to know, for scientific analysis, the exact date of collection? This is strictly for informational perposes and not legal. Getting another buccal swab is not possible as he does not wish to be bothered further.

    • KD says

      Daren, If your sample is older than 6 months, the sample may not have enough DNA to provide a conclusive result, but we can always try. As for the collection date, you can put down the date you swabbed your son and then put a written note of the alleged father’s swabbing scenario. You can also contact client support and let them know about your situation. They can make a note on your case. Client support’s number is 1-888-404-(GENE) 4363. Good luck! Thanks for trusting IDENTIGENE!

    • KD says

      Shay, IDENTIGENE recommends that you send off your DNA within 6 months of collection. If your samples are older than 6 months, we ask that you contact our client support staff so that they are aware of your situation. If the laboratory cannot pull DNA from the swabs, they will contact you for a retest. If you need to store your samples, please make sure they are stored in a safe, dry space within their sealed specimen envelopes. If you have any other questions, please feel free to contact us at 1-888-404-(GENE) 4363.

    • KD says

      Kamuai, It is unlikely that the results would be tainted. A common misconception is that we use the saliva for testing, when actually we test the cheek cells. If in the rare case that the samples did mix, we are able to detect if there are multiple DNA profiles on one sample. If we find that the sample has more than one DNA profile on a given sample, we will contact you and offer a free recollection kit which we will send to you in the mail. Hopes this helps! If you have any other questions feel free to contact us at 1-888-404-(GENE) 4363.

  43. Iris Morales says

    Can a paternity test – dna sample be contaminated if it was done incorrectly… say rubbed it too long inside the cheek –to the point where they inside of cheek bled?

    • breanna says

      IDENTIGENE provides simple instructions with each DNA paternity test kit. We advise participants to wait one hour before swabbing after they eat or drink (which includes breastfeeding). One misconception is that eating and drinking can alter DNA results. The only thing contaminents like foods or liquids can do is block the swab from grabbing the DNA off of the cheek. If this happens, we will contact the participants for a retest. As far as blood, blood cells and cheek cells contain a person’s DNA. The DNA is not different; it is a unique genetic fingerprint for that individual.

      We hope this information is helpful. Let us know if you have any more questions and we will be more than happy to help. 1-888-404-4363 Thank you!

  44. Alice says

    My child me and dad was swobbed. My child and I were swobbed together. But the dad was swobbed from prison. The results came back he wasn’t her father. When I asked him how was he swabbed he said from mouth but he said she sat the swob on a table and she only used one could this have contaminated the test

    • breanna says

      Alice,
      First, please contact our client support staff at 1-888-404-4363 with your case number and they can confirm the amount of swabs we received from each participant. We run each “excluded” test twice so we would have required at least two swabs before submitting a result. We look forward to speaking with you soon. Thank you.

  45. wondering says

    Can a sample be tampered with if a tips are doused under a faucet of water, then the fathers sample swabbed by the mother?Is the fathers DNA tested to make sure he is male? Can water affect the test?

    • breanna says

      Wondering,

      Yes, a sample can be contaminated if two DNA profiles are collected on one sample, however, we will be able to detect any contamination once the testing begins. We can detect if there are two different DNA samples on the same sample swab because it will show two different DNA profiles. The DNA itself cannot be changed however, so if the samples are not contaminated, the lab will be able to process the testing and produce an accurate result.
      In the event that the samples are contaminated, we do offer a free recollection kit which we will send out to you in the mail.

      We also test each sample for gender and compare it to what was indicated on the sample envelope. If there are any discrepancies between the two, our client support staff will contact you. Hope this helps to answer your questions. Please contact our client support staff if you have any further questions regarding your test at 1-888-404-4363. Thank you!

  46. Marissa says

    We all took a paternity test but not even 5 minutes before the test we ate a banana not knowing it could mess with the results. Could the paternity test come back wrong because of that?

    • KD says

      Dear Marissa,
      No, eating or drinking before a test will not change or alter the DNA in any way. The only problem that could result would be that the food blocks us from collecting DNA from the swab. This is why we ask for three seperate swabs from each participant. It is unlikely that all three would be affected by the banana. If you have further questions, please contact our client support staff at 1-888-404-4363. Thank you.

  47. Randy B says

    My wife demanded that I do my sample in front of her while sitting in my office. I did this to appease here not thinking much of it at the time.

    I left the room for about 10 minutes and when I came back I swore the ziplock envelopes were in a different order then how i left them. So with this I opened the enveloped in question”potential other father” swabs, washed the father swabs under hot water, dried them, then re-swabbed them with my DNA and re-sealed them. Tests came back as my children. Am I just being too worried here, could any of the other mans DNA remained after washing to cause a false result? Thank you for the answer.

    Randy

    • breanna says

      Hi Randy,

      There is a possibility that samples can be contaminated but we will be able to detect any contamination once the testing begins. Our testing will detect if there are two different DNA samples on the same sample swab because it will show two different DNA profiles. The DNA itself cannot be changed however, so if the samples are not contaminated, the lab will be able to process the testing and produce an accurate result.

      If however you are still concerned, we would recommend a legal test. A legal test will eliminate any doubt about what samples were sent in for testing as legal tests require a third-party collector to handle the paperwork, witness the collection and mail the test to our laboratory. Feel free to give us a call at 888-404-4363 with any further questions you may have. Thank you.

      • Identigene says

        Hi Mr Holmes,
        Thank you for your comment. In order to have a complete match, all the markers must match. If there are more than 3 “mismatches” the alleged father is then excluded as a potential match. Please have in mind that our highly trained and educated team does a thorough analysis on the DNA samples received. If you have any more questions or concerns, please call us at 1-888-404-GENE, Monday-Friday 9AM-6MP ET. Thank you for your comment!

    • breanna says

      Hi Kristen,

      If you sent your swabs using the pre-paid envelope included in your test kit, it takes 7-10 business days, depending on where you send them from, to receive the samples at our lab. Once we receive samples it takes two business days to process and get results. Another thing to be aware of is that we don’t accept mail on the weekends or on holidays. This week we are closed on Thursday and Friday for the Thanksgiving holiday. You are more than welcome to call our client support staff to check the status of your samples and if we have received them (1-888-404-4363). If you listed an email on your order form, you will receive an email notifying you when we receive your samples and when testing is complete.

    I Recently Had A DNA Test Done For My Daughter And The Alleged Father Came Back NOT The Father Of My Daughter, I Really Beleive That The Test Is Wrong Or Rigged I Know It Sounds Crazy But He And I Both Know He Is The Father The Day I Coneived Adds Up To The Day I Had My daughter. He Had His Test Done A Week Before Me And My Daughter Were Tested And I Never Received The Results Of The DNA But He Did!! Then I Got A Paper In The Mail For NonCooperation Saying I Never Showed Up For My DNA Test!! Should I Get Another Test Done??

    • breanna says

      Hi Mya,

      If you didn’t have a legal paternity test, there is a possibility of participant fraud, meaning the samples sent in may not be from the correct people. We would recommend having a legal paternity test done. In a legal paternity test, a designated collector will verify photo ID, collect a photo from participant, witness sample collection and mail the samples directly to our lab. This option gives participants peace of mind that we have received the correct samples and that the samples have not been tampered with. If you would like to learn more about a legal paternity test, please call our friendly client support staff at 1-888-404-4363. Thank you!

  49. amy says

    what is percentage that a false negative could occur. I was with same for 3 plus years and they excluded him as the father for prenatal dna test now he hates me. I received blood transfusion one month before and they have agreed to rerun tests but they didnt say if they found 2 dna profiles in my blood they just sent me test results as fact. This is confusing and I dont know what to do. When I talked to them they didnt say they had anything on file about contaminated anything. Also we went together and nothing was tampered with when taking samples we were never apart and watched each other the whole time all the way to going in store to mail

    • breanna says

      Hi Amy,

      This doesn’t sound like a test that IDENTIGENE performs, as we don’t collect blood samples. We recommend contacting the lab that conducted the test to ask about the possibility of a false negative and any other questions you may have about your specific test. They would likely be able to tell you if your blood transfusion could effect the results. Best of luck to you!

    • breanna says

      Hi Tonio,

    In the nineties when u had to go to the lab and swap yourself and had to be recalled back because they forgot to swap mom ( 2weeks) in the mean time what are the odds of having a incorrect test. It said my husband of now wasnt the father but the kid looks alot like him. From hair nose lips… etc.

    • breanna says

      Hi Amber,

      I’m sorry, but we’re unable to advise you on the accuracy of your previous test, as it wasn’t with IDENTIGENE. We recommend contacting the lab that conducted the test and ask about their accreditations, safeguards and controls for testing.

      If you feel you would like to take another paternity test, IDENTIGENE offers a home test which can be bought at CVS, Rite Aide, Walgreens or Walmart for $29.99. Once you buy your kit you can collect all samples by swabbing each participants cheeks and send in your $129 lab fee. Once the samples have arrived to our lab, testing takes 2 days. You can get your test results online with a secure username and password, call in and receive them by phone, or request a hard copy be mailed to you–or a combination of these. If you have any further questions about our test, you can contact us at 1-888-404-4363.

    hi could you advise me how 5 of my dna profiles are present in a childs dna profile how they can be 100% certain i am not her biological father, i was told that 10 out of the 15 were not there but surely if there were 5 there that cant rule me out 100 percent can it

    • breanna says

      Hi Robert,

      This is a good question, and one that we get somewhat frequently.

      All of the human race have very similar DNA, so it is inherent that there will be some matching DNA among all individuals. With paternity testing, in order to establish a paternal or maternal relationship, the child must have matches at all locations from each side–one from the mother and one from the father. This is simply because a child inherits half of it’s genetic information from both parents. The exception to needing all locations to match is genetic mutations which happen, but rarely. In the case of genetic mutations, there can be mismatches at one or at most, two locations. Our genetic scientists can determine the likelihood of a genetic mutation by doing further testing.

      In your case, it looks like the child inherited similar DNA, which matched yours at only 5 locations. This means that there is no paternal relationship as the child should match your DNA at all locations except in the case that there is possibly a genetic mutation or two.

      Hopefully this helps you understand a little more on this subject. If you have any further questions, please feel free to contact our friendly client support staff at 1-888-404-4363. Thank you.

  53. Leo says

    Hi, I took the home test with the mother and child. The results came back as not a match. The mother feels that I may not have swabbed the child well enough for an accurate reading or that contamination changed the result. I don’t believe that but I’m not an expert. Are either of these situations even possible? Thank You.

    • breanna says

      Hi Leo,

      If you tested with IDENTIGENE, no, neither of these situations is possible–let me tell you why. At IDENTIGENE we have many controls in place to help monitor possible problems with testing and also to safeguard against potential paternity testing fraud.

      In both cases, not having enough DNA for testing and any kind of contamination, would result in our lab contacting the participants for a recollection of samples. In regards to not having enough DNA for testing, our lab halt testing as not enough DNA was available to complete testing, thus your account would be on hold until we received those recollected samples. Though contamination of samples is rare, but possible, it will not effect or change DNA. Contamination simply inhibits the ability to extract enough DNA for testing, thus resulting in a recollection of samples before testing can be done and a result is released.

      If you want to learn more about this, you are welcome to contact one of our friendly client support staff members and they would be happy to answer your questions. Their phone number is 1-888-404-4363. Thanks!

  54. alie says

    My daughter has vitiligo (skin disorders), which i understand is caused by immune disorders. i did a test and it came out as 7 out of 15 did not match. i am not convinced about this result. i am also thinking that i may have mixed her samples in the same envelope. please help clarify this for me. if i need to re-do the test or maybe include the mum for more accurate results.

    • breanna says

      Hi Alie,

      Your daughters skin and immune disorder will not affect or change her DNA or your paternity test results. If however, you are concerned that you have mixed more than one sample on her collection swabs or through some other means, you don’t need to worry. We test to make sure that we receive samples with only one individual’s DNA. This means when the sample swabs come to our lab, we test to make sure there is 2 alleles (each person has 2 alleles) and not 4 alleles, which would signal that we have 2 DNA profiles for the sample/s. If we do receive samples with more than one set of DNA, we call the participants to recollect the sample/s. In answer to your second question, if you have received a conclusive (yes/no) answer to your paternity question, including the mother will not change the results. We encourage the mother to include her sample so that we can come to a conclusive (yes/no) question. Most of the time we can identify the answer without the mother, but having the mom helps if results are uncertain as to the answer.

  55. Shakeya Willams says

    If the mother is not swabbed and no sample sent in for her and just the child and alleged father is swabbed and sample sent in can this have an effect on the results?

    • Identigene says

      Hi Shakeya,

      We always recommend sending in samples for the mother. Without the mother’s samples, there is a possibility of getting inconclusive results, or in other words, we are unable to release a yes or no answer to your paternity question because there is not enough DNA to come to a conclusion of paternity. That being said, however, many tests are able to contain enough DNA information to come to a conclusion.

      If only the father and son sent in their samples and you have received a conclusive (yes/no) answer in your results, this means that we were able to determine the paternity just using those samples. If our lab can’t give a conclusive answer because there is not enough DNA information to clearly distinguish if he is the father or not, we will contact the participants to see if the mother is available for testing. It is very rare that if all three participants test, that results will come back inconclusive. If you have any other questions regarding this please feel free to contact our friendly client support team at 1-888-404-4363. Thank you!

  56. Casey says

    I recently had a test done but only swabbed the man and my baby. Could the results come back different if I too swabbed? Also he was smoking pot inbetween swabs..could this have messed anything up?

    • Identigene says

      Hi Casey,

      We encourage the mother to be included in the testing. Sometimes the lab does not have enough DNA between the father and the child to come to a conclusive answer (yes or no) that he is or is not the father. When you include the mother’s samples, this will allow the lab to see what part the child’s DNA is definitely from the mother and which is left to the father. That being said, we still do get conclusive answers without the mother. If we find that a test comes back inconclusive, meaning we can’t say for sure if he is or is not the child’s father, we will contact the participants on the test to see if the mother is available to send her sample in as well.

      Regarding your question about contamination because of smoking, this cannot change the results of your test. Though rare, contamination of the sample can happen through eating, drinking, smoking or other means within the hour before you take the test. This does not mean that it can change the actual DNA, but simply masks the amount of DNA we can extract and use for testing. Sometimes we won’t have enough to conduct the test. At that point, we if do not have enough DNA for testing, we will contact the participants for a recollection of the sample.

      If you have any other questions, please feel free to contact us at 1-888-404-GENE (4363) M-F 9 a.m.- 8 p.m. ET.

      Hi Lex,

      Identigene is a highly accredited lab which means we adhere to the highest laboratory standards available today. In addition to abiding by our accreditation’s standards, we have many self-made procedures and polices to ensure 100% accurate testing. you can read about our accreditations here: http://www.dnatesting.com/dna-laboratory/dna-testing-laboratory-accreditations

      In regards to probability accuracy, currently, the highest probability of paternity that any lab can produce is 99.99%. This percentage means that there is a 99.99% chance that the alleged father being tested is the father. Anything that is 99% or above is accepted by courts of law and for legal purposes. Theoretically speaking, to get 100% probability of paternity, every male on earth would need to be tested in order to rule him out as the father. As you see this is nearly impossible.

      If you have any additional questions refarding our test or accuracy, please contact us at 1-888-404-GENE(4363), we would love to speak with you!

  57. mika says

    Two questions

    1: smoking right before the test can mess it up?

    2: Say the “father” tests two different kids. Will his dna number results be the same on both tests?

    • Identigene says

      Hi Mika,

      Eating, drinking or smoking before swabbing for samples cannot change the end results of your paternity test or change or alter DNA. Though rare, contamination of the sample can happen through eating, drinking, smoking or other means within the hour before you take the test. This does not mean that it can change the actual DNA, but simply masks the amount of DNA we can extract and use for testing. Sometimes we won’t have enough to conduct the test. At that point, we if do not have enough DNA for testing, we will contact the participants for a recollection of the sample.

      If the father tests for paternity for two children, the allele values (the numbers listed under “Alleged Father”) will not change. Each child however may inherit different allele values from the father. For example, say the father’s allele value on Genetic System “CSF1PO” is “9,11”. One child may inherit allele value 9 whereas the other may inherit 11. (See example below) Because the father and mother will not always pass the exact same allele to every child they have, the Relationship Index will also change.

      CHILD A
      Genetic System/ Biological Mother/ Child/ Alleged Father
      CSF1PO/ 10,12/ 11,12/ 9,11

      As you can see from the example above, Child A has inherited an allele value of 12 from his mother and an allele value of 11 from the father.

      CHILD B
      Genetic System/ Biological Mother/ Child/ Alleged Father
      CSF1PO/ 10,12/ 9,10/ 9,11/

      In this example, Child B has inherited an allele value of 10 from his mother and an allele value of 9 from the father. Each child can inherit different allele values from each parent. If each parent always passed on the same allele values to all of their children, they would have identical DNA.

      If you need more clarification on these questions, please feel free to contact us at 1-888-404-GENE(4363) M-F 9 a.m.- 8 p.m. ET. Thank you!

    • Identigene says

      Hi Ashley,

      Any way you take a paternity test, whether that’s by swabbing for cheek cells or blood, they are both accurate and reliable forms of testing. The difference between the two is that getting cheek cells is less invasive and painless when compared to using blood for testing, DNA in your cheek cells and your blood is the same. If the result came back as 94% probability of paternity, we do not consider that to be a conclusive result. This means that there is not a conclusive yes or no answer for paternity, sometimes this is because the mother didn’t test. Usually when the biological mother tests, you have a higher possibility of getting a conclusive yes or no answer. If they tested with Identigene, there is usually a paragraph below the conclusion section explaining more about the results. Another possibility is that there is an alleged father who is closely related to the tested alleged father. They will have more similar DNA than that of another unrelated alleged father so if there is any way that the close relative of the alleged father could be the father he should also be tested and the laboratory notified.

      As for your question about contamination, there is no way to fake or falsify a positive paternity test. However, in your case, it doesn’t look like the results came back conclusive. If you have any other questions, you are welcome to contact us at 1-888-404-4363 M-F 9 a.m- 8 p.m. ET. Thanks!

    My friend is trying to get a sample from her boyfriend without him knowing. If she would get his spit bottle that has chewing tobacco in with the salvia to get a sample. If she’s does that will that make the test false or even work?

    • Identigene says

      Hi Yvonne,

      We have other means of testing non-standard samples, or samples not obtained by using a buccal swab. These are the swabs included in our retail kits. Non-standard samples do cost more to process. The sample that you mention may not yield a high amount of DNA because it could be potentially contaminated because of the tobacco. In order to submit a non-standard sample, your friend will need to contact us.

      In regards to getting a sample from her boyfriend without his acknowledgement, we discourage this as we have found that it is beneficial for all parties to be involved. If the boyfriend has custody of the child, he will be able to obtain results of testing if he knows a test was done, even if he was not included on the test.

      Please call us at 1-888-404-4363 to learn more about non-standard samples.

    I took a home test and forgot to mail it and left the kit in my car for 3weeks in the middle of winter. Could that effect the results?

    • Identigene says

      Hi Curious Momma,

      This will not effect the results of your test. Buccal swab samples are generally okay to be stored for up to 6 months before processing. We do recommend that you store them in a dry place store in their sample envelopes. If we find that the samples do not yield enough DNA for testing or if there was contamination, we will contact the participants to get a recollection of the sample at no cost to you. If you have any other concerns, please feel free to contact us at 1-888-404-GENE, Monday- Friday, ET. Thank you!

  61. Amber says

    Did a test with you a couple of months ago and the alleged father only swabbed himself and the baby and I did not swab myself. He took the test with him and mailed it off and also took the extra swabs with him that wasn’t used. Is it possible that he could have used the extra swabs on hisself and switched them with the child’s? The result came back he was the father, but I don’t think he is. On the results everything was the same ?!

    • Identigene says

      Hi Amber,

      Because of our laboratory accrediation guidelines and our self made policies and procedures we check for the same DNA profiles within the same test. This means that if the alleged father used the third set of swabs for the mother or the child, we would detect that there were two supposed different profiles that are the same, but should be different. If this happens we would contact the participant and get new samples. We also check for the gender of each sample, mean an alleged father’s DNA could not pass for a mother’s sample and vice versa. If you would like to contact us further or have us look into your specific case, please contact us at 1-888-404-4363 and we would be happy to help you with any other questions you may have. Thanks for choosing Identigene!

  62. srenee says

    My boyfriend took a legal standard DNA test today at a facility with the child in question. Two flags pop up to me and because I was not there I am not to know the possibility of contamination or if there should be an alarm in the first place. First they drank orange juice five before the appointment not the recommended hour before. Second when he mentioned this to the worker she had my boyfriend go wash his mouth out with water or drink it either one. Before he could stop the child, the child too picked up the same cup and drank from it and the worker proceeded to test them. Would this all have voided the possibility of an accurate reading and they should’ve been retested at a later schedule?

    • Identigene says

      Hi SRenee,

      Contamination by food or drink will not effect the outcome or the final results of a paternity test. When a sample is contaminated, it simply doesn’t allow us to gather enough DNA for testing, it masks the DNA. The DNA itself cannot change. If we find that there is not enough DNA for tesing we would contact the participants and arrange for a recollection of the samples. The recommended hour to wait is to avoid recollection and delay of results. If you have any further questions, please feel free to contact us at 1-888-404-4363, Monday-Friday 9 a.m.-8 p.m. ET. Thank you for your question.

  63. Missy says

    If there are 2 potential fathers and they are of completely different races (eg. middle eastern vs. Caucasian) is it necessary to have both potential fathers tested for paternity?

    • Identigene says

      Hi Missy,

      This is based on personal preference, but you may be able to save a little money by starting out testing one alleged father. For example, you could start the process by testing the most likely alleged father and child. If the result comes back positive you can stop the process and save money you would have spent on additional testing. If the result comes back that he is not the father, you can add an additional alleged father to the case for only $89 if he is added to the test within 30 days of starting/opening the test. This will help you avoid paying for two separate tests. You can also test both alleged fathers from the beginning. This will cost you $159 (cost of kit and lab processing for father and child)+ $89 (lab processing for additional participant). If you have additional questions, please feel free to contact us at 1-888-404-4363. Thank you!

    • Identigene says

      Hi Jane,

      As long as the race description accurately represents the child and father’s race, you have no need to worry about the results accuracy as they will be accurate. If however, they indicated the wrong race description, the lab should be notified of the change as there are different equations used for difference race descriptions. Please have him contact us at 1-888-404-GENE if this is the case. Thank you!

    • Identigene says

      Hi Keyna,

      Yes, the sample will still be useable. To avoid contamination or molding of the sample, do not placed used swabs in the plastic, but in the sample envelope in a dry cool place until you are ready to send the samples in. Samples are generally good for up to 6 months.

  64. Tylerrr says

    If I had sex with a girl in September 6 and the baby was born in may would he be mine the baby came out on time and everything she doesn’t think he’s mine but Iwant to know what you think

    • Identigene says

      Hi Tyler,

      There are many things that can hint at the paternity of a child. Timing and physical characteristics of the child are two of the most common. However, those methods are not reliable. The only true way to know for sure is through a DNA paternity test.

      We suggest you ask the mother if a simple DNA paternity test can be conducted. The test is painless and simple. All you need to do is buy the Identigene kit at your local drugstore or supercenter (CVS, Rite Aid, Walgreens or Walmart). The next step is to swab the father and child and mother for cheek cells. You will then fill out the necessary paperwork and send that along with the samples to our lab. Once the samples arrive to our lab, testing takes 2 business days and results are available online.

      If you need more information on our test, please feel free to visit DNAtesing.com or contact us via phone at 1-888-404-GENE. Thank you!

  65. Sam says

    If the suspected father spat into a test tube and I left it in a fridge and after 2 months i dipped the swab into the saliva and received a negative result would that be accurate? I ovulated on the night we conceived and my baby looks like his twin and nothing like the other man who I had sex with 2 days before my period it doesn’t make sense.

    • Identigene says

      Hi Sam,

      If you received a yes or no answer on your Identigene test result sheet, this means that there was enough DNA for testing and your results will be accurate as long as the we received samples from the correct or intended participants. This meaning that someone one did not falsify samples or send us someone else’s sample.

      Although the child’s physical characteristics and timing of conception may hint at the paternity of a child, the best and only reliable way to know for sure is a DNA paternity test. If the test with the suspected father came back negative (not the child’s father) it would be best to test the other possible father.

      If you have other questions, please give us a call at 1-888-404-GENE, Monday- Friday, 9 a.m.- 8 p.m. ET.

  66. coya says

    If the child and father was swab and the numbers are similar and some are missing can it be contaminated or alter to ready that he is not the biological father

    • Identigene says

      Hi Coya,

      If you have received a conclusive result, either a yes (not excluded) or a no (excluded), our lab did not find a need to recollect due to contamination of the samples. Our highly accredited lab is 100% accurate based on the samples we receive and would notify you if samples need to be recollected. If you are still questioning the results, we recommend doing a legal paternity test, where a third party will witness, collect and send the swabs. You may also ask yourself if you were able to witness the collection and sending off of the samples to avoid tampering.

      Hopefully this helps in answering your question. If you continue to have questions or need more assistance our friendly client support staff would be happy to assist you. You can call us at 1-888-404-GENE, Monday- Friday, 9 a.m.-8 p.m. ET. Thank you for your comment!

  67. ashley says

    We completed a test and put the swabs in their envelopes and then into the mail envelope before they were dry…could they have touched and combined to cause an 89% chance that he is the father??? This baby looks nothing like our daughter or anyone in his family. We are ok with her being his but something doesn’t feel right and knowing the test were still wet when put together bothers me. I didn’t have them at opposite ends either. Both swabs were on the same side of the envelope touching but were inside their own envelope but the outside of both were wet when put immediately into the main one to mail. Should we do another test?

    • Identigene says

      Hi Ashley,

      This is a great question and is fairly common. Although, there is a very slight possibility that DNA could be added or mixed to samples in the scenario you mentioned, we have many procedures that ensure that this will not effect results and another test will not produce different results.

      For example, each sample or swab is tested to make sure that there is not more than one DNA profile, this means that if we find more than one DNA profile on a given sample, we will call the participants to recollect. In addition, we test for gender on each sample, this means that the mother and father’s samples could not be confused and the same goes for the father and a female child or the mother and a male child.

      As for the 89% probability of paternity, was the biological mother included in the test? It sounds as if the results you received were most likely “inconclusive” meaning no concrete yes or no answer was obtained. The mother helps us to determine the allele values that the child had to inherit from the father. When we take the mother’s DNA out of the equation, it is easy for us to see what is left over and has to be inherited from the father. Chances are that if the mother was not included in the test, the test could come back inconclusive.

      We suggest you contact our client support staff to talk to them more about your inconclusive result to see if there is anything that can be done to get a conclusive result. We can be reached at 1-888-404-GENE, Monday- Friday, 9 a.m.- 8 p.m. ET. Thank you for your comment!

    Hi could my boyfriend’s ex had swabbed my boyfriend’s swab sticks and also the babys swab sticks with my boyfriend’s dna and the test comming back that he is the father?

    • Identigene says

      Hi Black Beauty,

      No, our laboratory checks each set of samples to make sure none of the samples have the same DNA profile. If we find that two people have the same DNA profile, we will contact the participants to recollect the samples. Thanks for your question!

  69. maryj says

    Hi im coulerd and my babies father is white im very dark skinned but my baby has everything of his father the eyes the color even the same birthmark at the same spot there is actually nothing of me and I only been with him but the test results come back negative we did a blood test,me he and rthe baby . And on the paper I received stand that we are coulerd and he is Caucasian please answer me I wnt too do a dna test now.

    • Identigene says

      Hi Maryj,

      Although physical characteristics can hint at the paternity of a child, the only sure way of knowing is by, like you said, having a paternity test done. It does sound like you had a paternity test done previously, were you able to watch the father getting his blood drawn? It is important that the test is done with the correct participants. You can see that if someone was to falsify their samples, the test wouldn’t accurately represent the answer to the question you are wanting to know.

      We suggest either buying an at home paternity kit from your local CVS, Rite Aid, Walgreens or Walmart near the pharmacy and watching the sample being collected and accompany it to the mail so you know that all participants are honest or having a legal paternity test. These two tests are tested the same in our laboratory, the difference is that a legal paternity test is witnessed, collected and mailed by a third-party collector. A legal paternity test establishes a chain-of-custody and is able to be used in court if needed.

    • Identigene says

      Hi Robert,

      This is a great and very common question! Dropping the swab may result in a possible contamination, however, it is unknown if contamination did occur before actually sending in your swabs for testing. Our lab does test for contamination with any samples received. Contamination does not change DNA or results. However, if our lab is unable to use the samples you provided due to any contamination, we would then contact you and ask for a recollection.
      I hope this helped answer your question. You can also contact our friendly client support staff if you have more questions or concerns. You can reach them at 1-888-404-GENE, Monday- Friday, 9 a.m.-8 p.m. ET.

          Hi Robert,
          Receiving a conclusive result from our lab, yes (not excluded) or no (excluded), mean that there was no contamination. Our lab does test for contamination, and would have notified you if there was a need for a recollection of your swabs. I hope this helped answer your question.

            Hi Justin,
            Our lab will release results when there was a clean and sufficient amount of DNA extracted. Our lab would contact you if your samples were contaminated and ask for a recollection at that point. If you obtained a conclusive result, yes (not excluded) or no (excluded), there was no contamination on your samples. I hope this information is helpful.

            I was told that if I get results back no matter what they said that there would not be any contamination . and this is saying that if I get a conclusive result there was no contamination. is there only conclusive results. can you explain

          • Identigene says

            Hi Justin,
            Getting a result back does mean that our lab found no contamination which is why we were able to release a firm result. There is such thing as an inconclusive result. Inconclusive results occur when there was no concrete answer reached, whether it is a yes (not excluded) or a no (excluded). This typically will happen when the father and child have similar markers among a population, however, including the mother will help yield a conclusive result in that case. Our lab will not release results when there is contamination present, they cannot test contaminated samples. Our lab would notify you in case of contamination. If you have any more questions please call our friendly client support at 1-888-404-GENE, Monday-Friday 9AM-8PM ET. Thank you for your comment!

            sorry but one more question to better understand, if I get a result back no matter what the result say does it mean that there was no contamination.

          • Identigene says

            Hi Justin,
            If you received a result, like the following examples:
            “John Doe is excluded as the biological…” or ” John Doe is not excluded as the biological…” your samples were not contaminated because our lab was able to reach a conclusive result. If your result reads that it was inconclusive, there is a small chance your sample was contaminated, however, our lab would have contacted you in this case. I hope this information helps. If you have any more questions please call our client support at 1-888-404-GENE, Monday-Friday 9AM-8PM ET. Thank you for your comment!

            My results said I was not excluded. . But my numbers weren’t 99.99%… it was 97.50 and I was told that any thing under 99.9 was inconclusive. can you explain.

          • Identigene says

            HI Mark,
            Typically when results aren’t higher than your 97.50%, it means the DNA was not able to yield a stronger result on its own. This can happen because the mother was not included in testing to strengthen the result. If this is the case, you are welcome to include the mother. Testing with the mother has no additional charge. Please contact our client support for more case specific details. There we can advise you how to obtain a stronger result. I hope this information helps. You can reach us at 1-888-404-GENE, Monday-Friday 9AM-8PM ET. Thank you for your comment!

      • says

        I am sorry, but can you explain this sentence to me( it is unknown if contamination did occur before actually sending in your swabs for testing.) and can you explain what conclusive means. thank you.

        • Identigene says

          Hi Robert,
          When a swab is contaminated it means that the swab contained other material(s) besides the DNA, which interferes with testing and results. Whether a participant had eaten something prior to collection or a swab was dropped on the ground, until we can test the swabs here in our lab there is no way to know if the swabs were contaminated, for the human eye cannot detect DNA contamination.

          A conclusive result means that a definite or concrete answer to your paternity question was achieved. We were able to give a yes (not excluded) or a no (excluded).

          I hope that this helped answer your questions. If you have further questions or would like to discuss your results, please give our friendly client support team a call. You can reach us at 1-888-404-GENE, Monday- Friday, 9 a.m.-8 p.m. ET.

      Hi Ken Mcclintock,
      Thank you for your question! The preferred collection method for DNA samples industry wide is a cheek cell sample which is taken by swabbing the inside of the cheek in the mouth using a special swab that we provide in our kits. This is the easiest sample to work with and any other type of sample will be considered a special specimen. All special specimens require an additional fee of $400 to process and we cannot guarantee that we will be able to produce results with a special specimen. We also require a consent signature for all participants being tested. Since the children you are looking to collect are adults, they would need to provide consent to have the specimens tested.

      You will need to contact us at 1-888-404-GENE, Monday- Friday, 9 a.m.-8 p.m. ET for an approval to send the specimen into us. All special specimens must be pre-approved before they will be accepted. I hope this answers your question. Feel free to call our friendly client support, we would be happy to assist you!

    • Identigene says

      Hi Chris,

      Contamination may occur to the sample when it comes in contact with an area that does not consist of DNA from the participant. I understand that the swab was bitten by the participant being tested. In this case you should be fine, but there is still a small chance for contamination. This is why we recommend not eating or drinking before the collection of DNA on the swab. However, contamination cannot be seen by the human eye and our lab does test for it. In the event that there were to be some issue with your swab, we would contact you and send a recollection kit at no charge to acquire a clean sample. I hope this helped answer your question. Please feel free to contact our friendly client support if you have any more questions! You can reach us at 1-888-404-GENE Monday- Friday 9 a.m.- 8 p.m. ET. Thank you for your comment and patience!

    How soon after collecting the samples do they have to be mailed in? Do they have to be mailed in within a certain time length after collecting it? I just bought my test today and wanted to go ahead and get it do it. But it may be 2 weeks before I can send it in due to payment issues… Can I send it in then pay for it before I get my results? Or do you have to send everything together at the same time payment and all???

    • Identigene says

      Hi Courtney,
      Once the sample swabs are sealed up in the specimen envelope they will generally be good for about 6 months. If you need to hold on to the samples for any amount of time or reason, just make sure to store the specimen envelopes with the samples sealed up inside them in a safe, dry place and they will be just fine. The cells on the swabs only have a shelf life of 6 months. In order for our lab to begin testing, payment will need to be included whether you pre-pay over the phone or include it in a money order/cashier’s check when sending in your samples.

      I hope this helped answer your questions. If you have any more questions or when you choose to pay over the phone, you may contact our friendly client support at 1-888-404-GENE, Monday-Friday 9AM-8PM ET. Thank you for your comment!

      Hi Abbey,
      Thank you for your question! IDENTIGENE provides the most accurate testing available on the market today. We have worked extremely hard to put measures in place that prevent any mistakes from being made throughout the entire DNA testing process from beginning to end. This is why the accreditation we hold as a laboratory are so important. We are 100% accurate based on the samples we receive, retesting would not change the results once you have received a conclusive answer to paternity. You may also see more information on our accreditation in the link below.

      Our goal is to provide quality service and accurate results to all of our customers. The strict standards and procedures we follow extend to every single part of the process from the moment the samples arrive at our laboratory to the release of the analysis report when the testing is completed.

      An extremely important part of the process is how the samples are handled and managed as they travel step by step through each stage of the testing. Were you able to witness the collection, swabbing and sending of all the participants? If this is something that you were not able to be there for all participants collection process, we recommend a legal collection test. In the legal case, we have a third party witness, collect and send the samples to our lab, leaving no room for tampering the swabs.

      I hope this helped in addressing your concern. If you have any more questions please give our friendly client support a call. You can reach us at 1-888-404-GENE, Monday- Friday 9AM-8PM ET. Thank you for your comment!

        On the results there is no ethnicity listed for my child, it is blank. The father is listed as black and me as Caucasian which makes my child biracial. Will this have any effect of the accuracy of the results? Thank you!

        Abbey Autry

        • Identigene says

          HI Abbey,
          Thank you for your patience! We only require the ethnicity of the alleged father and the biological mother. Since we are determining paternity for the child, it would be difficult to say what ethnicity the child is without being certain who the biological father is. Leaving the child’s ethnicity blank will not affect the results. If your results did not exclude the alleged father, then the child would be of mixed ethnicity like you had stated. Knowing the ethnicity of the participants only helps with testing, and it would not define the accuracy or determining of the results. I hope this helped answer your question. If you continue to have questions, feel free to contact our friendly client support at, 1-888-404-GENE, Monday- Friday 9AM-8PM ET. Thank you for your comment!

    We took samples and then realized that they needed to be dry before placing in th envelopes can this give a false reading since they were next to the alleged fathers swabs whom s were also wet.

    • Identigene says

      Hi Debbie,
      Thank you for your patience! The swabs will be fine if they were all pertaining to the same participant. If the samples were possibly contaminated with another participant’s profile, we would most likely need a recollection. There is a chance the swabs will be fine and no contamination was done, however it is impossible to determine that with the human eye. Our lab does test for contamination, whether it is from food, beverage, or another person. Our lab would inform you and send a recollection kit at no charge to obtain the clean samples from each participant. If you would like us to send you additional swabs to collect the samples once again, you may call us at 1-888-404-GENE, Monday – Friday 9AM-8PM ET. Our friendly client support would be more than happy to assist you in sending more swabs. I hope this helped answer your question! Thank you for your comment!

    I have got my results back an they used his dna from 2008 and its 2014 can the results be right? my daughter ate some candy before taking the test can it make the test come back false?

    • Identigene says

      Hi Reka,
      Thank you for your patience in our getting back to you! Even with the 6 years that have passed in between the tests, DNA will have remained the same. DNA does not change over time, and as long as the same person was tested in both occasions, the same results will be obtained from 2008 if testing against the same participants in 2014.

      It is important the participants do not eat, drink, brush teeth, or smoke for at least one hour before the test. 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, the lab will be able to process the testing and produce an accurate result.

      In the event that the samples are contaminated, we do offer a free recollection kit which we will send out to you in the mail. I hope this information is helpful. If you continue to have any more questions, please feel free to call our friendly client support at 1-888-404-GENE, Monday-Friday 9AM-8PM ET. Thank you for your comment!

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 however, so if the samples are not contaminated, the lab will be able to process the testing and produce an accurate result.

      In the event that the samples are contaminated, we do offer a free recollection kit which we will send out to you in the mail. I hope this information is helpful. If you have any more questions, please feel free to call our friendly client support. You can reach us at 1-888-404-GENE, Monday- Friday 9AM-8PM ET. Thank you for your comment!

    What if you accidentally get saliva on the swab, and then swab the cheek over the saliva, will you still be able to determine paternity with the saliva?

    • Identigene says

      Hi Jessica,
      Great question! Some people do not carry enough or any DNA in their saliva, which is why the preferred method of collection is by swabbing the cheek for cheek cells. Were you able to swab the remaining 2 swabs in the cheek of the participant? If so, our lab will gather all the DNA from those swabs. Typically, we have the 3 swabs from every participant in case one swab does not yield enough DNA. Our lab will use all 3 if necessary to extract the DNA that is needed. In the case that the swabs did not yield enough DNA, our lab would ask for a recollection at no charge. If this does occur, we would get in contact with you and send the supplied needed. If you obtain a conclusive result, a concrete answer to paternity, our lab was able to determine paternity and recollection was not needed. I hope this information is helpful. If you have any other questions, please feel to call our friendly client support at 1-888-404-GENE, Monday- Friday 9AM-8PM ET. Thank you for your comment!

  75. Charles T. Miller says

    Can you perform a test on a sample taken from a glass, cigaret, or drink can, etc. We need to test a subject that will not submit to a mouth swab.

    • Identigene says

      Hi Charles,
      Thank you for your question! The preferred collection method for DNA samples industry wide is a cheek cell sample which is taken by swabbing the inside of the cheek in the mouth using a special swab that we provide in our kits. This is the easiest sample to work with and any other type of sample will be considered a special specimen. All special specimens require an additional fee of $400 to process and we cannot guarantee that we will be able to produce results with a special specimen. We also require a consent signature for all participants being tested. You will need to contact our friendly client support at 1-888-404-4363, Monday-Friday 9AM-8PM ET, for an approval to send the specimen into us. All special specimens must be pre-approved before they will be accepted. I hope this answers your question. Feel free to call us at 1-888-404-4363 with any further questions you may have and we will be more than happy to assist you! Thank you for your comment!

    if mother, and child was tested 8 months before the father, will that be an accurate test?

    • Identigene says

      Hi Edythe,
      Thank you for your patience! Are you referring to the swab collection time frame? Typically, we recommend to wait no more than 6 months to send in the kit once the participants have been swabbed. If the swabs were sent in after the shelf life expired, our lab would determine if a recollection was necessary if they could not extract enough DNA. If the swabs were able to yield enough DNA, testing would continue and results would still be 100% accurate based on the samples we received.

      In the case a recollection is necessary, we would contact you and advise the need for a recollection and send the additional supplies for no extra cost. Please also feel free to call our friendly client support at 1-888-404-GENE, Monday-Friday 9AM-8PM ET, we are more than happy to assist you. Thank you for your comment!

  77. ashley says

    My son was about 5 months when we did dna testing he drank a bottle before we did the swabs and the patential father also brushed his teeth can this affect the results?

    • Identigene says

      Hi Ashley,
      Great question! We do recommend to not eat or drink anything an hour prior to swab collection since there is a chance of possible contamination. If the samples are contaminated, our lab would contact you to let you know they are in need of a recollection in order to obtain a clean sample. We offer these recollections free of charge if they are necessary. If you receive a result from the samples you sent in, no recollection was necessary and our lab was able to extract a clean sample from each participant. I hope this information helps. You can always contact us at 1-888-404-GENE, Monday-Friday 9AM-8PM ET. Thank you for your comment!

  78. michelle baer says

    when a dna test is done do you have a certiin amount of time to send it in or does it have to send it in right away

    • Identigene says

      Hi Michelle,
      I understand you are asking how long the swabs will last after the DNA has been collected? If this is the case, swabs have a shelf life of 6 months after the DNA has been collected. Any time after that, we will recommend to recollect the DNA from the participants. I hope this information helps answer your question. You can always reach us at 1-888-404-GENE, Monday-Friday 9AM-8PM ET. Thank you for your comment!

  79. samantha says

    I had a DNA test done the father chewed tobacco right before we toke the test would that mess with the results

    • Identigene says

      Hi Samantha,
      We do recommend not to consume anything one hour prior to DNA collection because the DNA may become contaminated. If this is the case and the drug did contaminate the sample, we would not test with the DNA that was provided. We would ask for a recollection to obtain a clean sample before going through testing. If the tobacco did not affect the sample, we will release a result since the DNA was unaffected. In the case that a recollection is needed, it is free of charge and we will come in contact with you. I hope this information is helpful. If you have anymore questions, please call our client support at 1-888-404-GENE, Monday-Friday 9AM-8PM ET. Thank you for your comment!

      Hi SW,
      did you use our envelope to send in your samples? If so, our envelope can take anywhere from 5-10 mailing days to arrive in our lab. Upon our receiving your samples, we will send you an email to advise you we have processed your kit. I hope this information is helpful. If you have any other questions, please feel free to contact our friendly client support at 1-888-404-GENE, Monday-Friday 9AM-8PM ET. Thank you for your comment!

  81. misti says

    My step daughters mother wanted another paternity test done, and my husband agreed. But we think she switched hers and her daughters swabs. How will this affect the test? Will it come out negative because the childs mother is the one being looked at with the fathers or will the test compare mother(child in this case) and father as well?

    • Identigene says

      Hi Misti,
      Great question! If you have a concern of some swabs possibly being switched, we recommend you contact our client support and advise them of this possible switch. There, our lab can take extra precaution in testing and look for a possible switch. For better assurance, you may consider a recollection if you are not sure the samples were switched. For more information and case details, please call our friendly client support at 1-888-404-GENE, Monday-Friday 9AM-8PM ET. Thank you for your comment!

    • Identigene says

      Hi Mark,
      There are instances when you may receive samples that result as inconclusive. This may be because the sample was weak or there is not enough DNA to test to obtain a strong result. Typically, this occurs when the mother is needed to test. I hope this information is helpful. If you have more questions about inconclusive results, please call our friendly client support at 1-888-404-GENE, Monday-Friday 9AM-8PM ET. Thank you for your comment!

  82. says

    I was told that any thing under 99% was inconclusive. and I was told that if your results say that you are not excluded as the father, it was a conclusive result. my results was 97.50 but it said that I was not excluded as the father. can you explain witch won it is.

    • Identigene says

      Hi Jim,
      Anything below the 99% percentage, DNA can suggest a conclusion. 97.50% is still a fairly strong conclusion which is most likely why our scientists could leave the suggestion that you are not excluded. Did the mother test with you? If she did not, this may be why your results are not as strong up to the 99% mark. The mother will help to strengthen that result if she were to be included. I hope this information helps! If you have anymore questions please feel free to call our friendly client support at 1-888-404-GENE, Monday-Friday 9AM-8PM ET. Thank you for your comment!

      Hi Marvin,
      I understand you received a negative result meaning there was no relation between you and your alleged nephews? Unfortunately without any other available participants, IDENTIGENE cannot test any further. I recommend contacting the consulate office/embassy for further information on what you can do to settle a Visa at this point.

  83. says

    I recently had dna done for a possible bio daughter and myself. The reason being is that back in the 70″s they changed info. I have been searching in adoption sights for over 25 years. She has been searching for the same amount of time. The girl that tested with me seemed to share a parallel life. She looked like the Father and her children look like me. So we went forward with dna at 23 and me. It came back as a 0% match when everyone see’s the resemblance. 23 and me has a good rep or have there been problems in this area? I broke down and hired a private searcher. She came up with 3 possible matches one of them being the girl I just tested with. Hmmm. Can you help?????.

  84. Kay Landry says

    Hello my sons alleged father did a test behind my back and it came out to be he wasn’t the father. I read the results and it says they have 12 out of the 17 different tests they look for how come he is not the father ? And also he smoked before the test was done and I was not tested could that throw the test off ??? Please help

    • Identigene says

      Hi Kay,
      Thank you for your question! Seeing as humans share 99% of DNA, it is not uncommon to see some matches within two unrelated people. In order to be considered the biological father, ALL of the markers must match. Once 3 or more mismatches are found, a man can be excluded from paternity.
      Our lab does test for contamination when we receive the samples. We do recommend no consumption of any sort an hour prior before collection, however, we do understand that it may happen in some situations which is why our lab will test for contamination within a sample. If contamination is found, our lab will contact you and ask for a recollection. However, if the samples were found to be clean, we will continue testing and produce a result whether it is a concrete yes (not excluded) or no (excluded). I hope this helps answer your questions. If you continue to have any more questions or concerns, please call our friendly client support at 1-888-404-GENE, Monday-Friday 9AM-8PM ET. Thank you for your comment!

    Hello my ex girlfriend and I and her now boyfriend where going to test for a 3 yr old girl. I was just informed by a friend they did the test already and the boyfriend swab the girl and then used the same swab. What will this test show so I can tell my lawyer. Thank you for your time.

    • Identigene says

      Hi Dave,
      Thank you for your question! I am understanding you suspicion the collection process was done incorrectly, and the child’s swab was used by the man testing for the alleged father as his DNA? If this is the case, our lab will test to see if we have 3 DIFFERENT profiles, if our lab sees the the child’s DNA came back the same as another participant’s, we would contact the participants and ask for a recollection in order to obtain the correct sample. Our lab will not test the same DNA with each other. I hope this information is helpful, if you have any more questions, please call our friendly client support at 1-888-404-GENE, Monday-Friday 9AM-8PM ET. Thank you for your comment!

    Hello I have DNA results stating that I’m excluded as the father of a child. I followed the collection procedures to the letter, the samples was not contaminated in any way but the mother swears that I’m the father. Is there any way by which those results can be wrong? This was done through another testing facility in 2008. Should I do another test or should I just go by the results I have?. Oh by the way this was just an information test not a legally binding test.

    • Identigene says

      Hi Dexter,
      Thank you for your message. IDENTIGENE is a certified and accredited lab. We hold accreditation from AABB, NYSDOH, LAB, you can see our accreditation certificates on our website by following this link:

      http://www.dnatesting.com/dna-laboratory/dna-testing-laboratory-accreditations

      The at-home paternity test will not uphold in court since it was not collected or done by a third party. The at-home test is designed for the convenience of testing within your own home. This requires following the collection instructions correctly. Were you able to witness the child’s swabbing as well as sending or dropping the samples in the mail before arriving to our lab? Have in mind, that collection mistakes can be done accidentally or intentionally. Paternity fraud is real and happens all the time.
      Our lab is 100% accurate based on the samples we receive, unfortunately for the at-home test, we have no way of verifying that the samples we received for John Doe, are actually from John Doe. We trust our customer to provide us with the samples they are paying to test.

      In the 20+ years we have been in business helping our customers with paternity questions, we have not made a mistake and we take pride in providing our customers with accurate results. If you have any more questions, or would like to inquire a court-admissible test, please feel free to call our friendly client support. You can reach us at 1-888-404-GENE, Monday-Friday 9AM-8PM ET.

  87. Jennifer Cotta says

    How can I get a paternal dna test if the person in question is recently deceased? the family of the deceased has a official copy of his dna record, how would, I go about using this copy and getting a dna test done on myself? would this be legal and effective? or should I got the route of a dna test with one of his living family members? sister, mother? ect….

    thank you

    • Identigene says

      Hi Jennifer,
      Our condolences to you and your family. Was the copy of the alleged father’s DNA record collected as a legal collection? Meaning there were witnesses and is admissible for court? If so, testing yourself in a court-admissible witnessed collection increases the probability the results may be admissible in court. To be certain if the results will be admissible in court may be up to the specific court or legal practice. You may want to consult an attorney to verify if it will be accepted. IDENTIGENE does offer other relationship testing as well. We offer Sibling tests, Avuncular and Grandparent tests for when the alleged father is unavailable to test. These tests are $399, and have a testing frame if 5 full business days. When testing with other first-degree relatives, it is important to include your biological mother, if possible, as well as any other relatives to the alleged father willing to test. This will decrease your chances of an inconclusive result. If you have more questions about any of our tests and would like to order one, please call us at 1-888-404-GENE, Monday-Friday 9AM-8PM ET, we would be more than happy to assist you! Thank you for your comment!

    • Identigene says

      Hi Annonomous,
      Thank you for your question! With all the samples we receive, we require a signature consent from the participant for their DNA to be tested. Unfortunately, needing to sign the consent will make it difficult to be discreet in DNA testing. I hope this information is helpful.

  89. Jenn says

    My sister is trying to find out who the father is for her 8 month old son. They recently did a blood test on the potential father, but had to do a swab test on the baby since he had a blood transfusion when he was in the NICU around 1-2 months old since he was born very premature. She just got the results back from the state today saying that the potential father tested negative and I’m really questioning whether the results were correct or not. My sister was told that they couldn’t test the baby by blood until he was at least a year and a half old, but is there another way that they could be more accurately tested that is a little more trustworthy??

    • Identigene says

      Hi Jenn,
      Thank you for contacting IDENTIGENE. The accuracy between cheek cells and blood cells is the same. Your DNA will not change between a blood cell and a cheek cell; therefore we would get the same answer with either testing method. Cheek swabs are usually the preferred method of testing for a couple of reasons. It’s easier for the client to collect the samples, its easier and safer to ship the samples, it’s easier to test the samples in the lab, and a cheek swab will generally last longer than a blood sample. There is also no specific age to do DNA testing, our DNA remains the same from the day we are born.

      I hope this information helps. Feel free to give us a call 888-404-4363 with any further questions you may have and we will be more than happy to help you. You can reach us at 1-888-404-GENE, Monday-Friday 9AM-8PM ET. Thank you for your comment!

  90. Kaela says

    My boyfriend has a daughter that looks nothing like him so he did your paternity test. He came home and said that he had put the baby’s swabs in his hand after swabing her mouth and then back into the original packaging they came in, not the envelope. Would these two things effect the test tremendously?

    • Identigene says

      Hi Kaela,
      Thank you for your patience! Our lab tests for contamination to ensure the samples received did not have another profile. If our lab detects samples are not clean, we will contact you and ask for a recollection in order to obtain a clean sample. Our lab will NOT test with a sample that is contaminated. IF you received conclusive results, this means our lab found the samples to be clean and recollection was not necessary. It would be impossible to know if the samples were truly contaminated by just looking at them, which is why our lab checks for clean samples once we receive them. While physical characteristics can be an indicator of a relationship, DNA is ultimately the best way to test for relation. I hope this helps answer your question. If you have any more questions or concerns, please call our friendly client support at 1-888-404-GENE, Monday-Friday 9AM-8PM ET. Thank you for your comment!

    • Identigene says

      Hi Emily,
      Thank you for your patience! We do recommend that participants do not eat (or chew) anything one hour prior to collection. This may increase the chances of the samples becoming contaminated. Our lab will test for contamination, and if it is found in the DNA samples, we will contact you and ask for a recollection. Our lab will not continue testing if the samples are not clean. If you received a conclusive result, the samples were found to be clean and testing went smoothly. Were you able to witness the collection and sending of the samples for all parties? Have in mind, mistakes can be made intentionally or unintentionally, which is why it is important to be certain the samples received in our lab were the ones you wanted tested.

    I have paternity test results and it turns out he’s not the father. If I showed you the breakdown of the results could you tell me if he would be the child’s uncle?

    • Identigene says

      Hi Sarah,
      The paternity test report given to you can only prove this man is not considered the biological father. You have the option to add the other alleged father within 30 days of testing for the price of $89. It is also very important for our lab to know if the two possible fathers are related. In order to test and see if he can be considered an alleged uncle, it would be best to do an avuncular test. This test is for alleged aunts/uncles when the possible father is not available for testing. It costs $399 and results are available after 5 business days. I hope this information is helpful. If you have any more questions, please call us at 1-888-404-GENE, Monday-Friday 9AM-8PM ET. Thank you for your comment!

  93. william says

    This is a doozy. After fighting with the mother of my child, yes Im on the birth certificate, I was informed by the mother that Im not the father. She had a test done but the bottom of the results state in bold print, “These results are not defendable in court due to the fact that the samples were brought in and not taken directly from one or more parties.” I couldn’t get the mother to take that document into court and the alleged fathers name is marked out from the emails I received. Now my question is, being I have several items in which the baby has teethed on, or had in her mouth, is it feasible to preform a dna test using one or more of those objects? I need my own test but a court ordered test cost more than I can afford and the mother refuses to allow me to preform a test of my own. Im in a rut here.

    • Identigene says

      Hi Williams,
      I understand the reasons you may need the test are for legal reasons. Any at-home test will not uphold in court, it will need to be a court-admissible test. Court admissible tests are $359 and are witnessed and collected by a disinterested third party. As for the items the child has placed in her mouth, they are considered special specimen items. Special specimens are not guaranteed to yield enough DNA for testing. They may also be contaminated with other DNA profiles. Special specimens cost an additional $400+ the lab fee (choice of at-home or court-admissible.) I hope this information helps.

    • Identigene says

      Hi Cristy,
      Thank you for your patience! We do offer an avuncular test at IDENTIGENE allowing an uncle/aunt of the child to test instead of the biological father. There is a higher chance for an inconclusive result, which is why we would highly recommend the biological mother to test as well. Any other first-degree relatives to the father would be of great assistance in testing. The avuncular test is $399 and allows up to 5 participants to test, including the child. I hope this information helps. If you have any questions, please call us at 1-888-404-GENE, Monday-Friday 9AM-8PM ET. Thank you for your comment!

      Swabs are good for up to 6 months after DNA collection has been completed. After 6 months, we recommend the DNA be recollected. I hope this helps answer your question. If you have any more questions or concerns, please call us at 1-888-404-GENE, Monday-Friday 9AM-6PM ET. Thank you for your comment!

    A friend of mine has a woman claiming her child is the son of her deceased son. A DNA test was done, and the results came back at 53% possibility, can this be considered conclusive? The samples were taken from the paternal grandmother and the baby, alone.

      Hi Jean,
      A conclusive result is a 0% or anything ABOVE a 99%, this means a 53% is NOT considered conclusive. Was the biological mother tested? If not, we highly recommend testing her as well to increase the chances of obtaining a conclusive result. If you have any more questions or concerns, please call us at 1-888-404-GENE, Monday-Friday 9AM-6PM ET. Thank you for your comment!

    I think the test was contaminated I had protected sex with a guy March 8,2010 and I had unprotected sex with my other kids father March 31.2010-April 1,2010.i have became pregnant my due date was december 21,2010 I’m telling the first guy it’s impossible for him too be the father because the dates don’t add up he keep saying he took the condom off but I know he didn’t if we had sex March 8,2010 my due date would have been November 25,2010 but instead it was December 21,2010 I gave birth 12/2/2010 my last menstrual was 3/17/2010 if it was the first guy my last menstrual wouldve been 2/25/2010 the first guy and my mom did a dna test behind my back and I strongly believe he either swabbed another one his kids or the test was contaminated I find it ironic that he would do something like this I even went as far as too ask my obgyn the conceptions date and he said the dates I listed above which is strongly making me think he altered the test as I said above the dates do not add what should I do because I know for facts he is not the father my baby looks just like his father same eyes nose mouth hands feet and ironically the same birthmark in the same spot please help me.

      Hi Shelly,
      Although physical traits are important, we cannot base paternity simply off of these physical characteristics. We highly recommend to do a DNA Paternity test and witness the collection of the child (or children), the alleged father and include yourself (at no extra charge.) With the lab fees as low as ever ($89), knowing the truth and getting a peace of mind is priceless. If you have any more questions or would like to order a DNA paternity test, please call us at 1-888-404-GENE(4363), Monday-Friday 9AM-6PM ET. We are more than happy to assist all your questions and concerns over the phone!

      Hi Aica,
      DNA is not changed by medical complications whether it is a sickness or disease, the DNA will always be half from the biological father and half from the biological mother. I hope this helps answer your question. If you have any more concerns, please call our friendly client support at 1-888-404-GENE, Monday-Friday 9AM-6PM ET. Thank you for your comment!
