DNA testing for paternity results has many benefits, from the peace of mind of knowing for certain that a biological relationship exists to knowing family health history and inheritance eligibility.
The method for collecting DNA samples for paternity DNA testing has many questioning whether blood samples would be more accurate than buccal (cheek) swabs. In short, the answer is no. Here’s a look at why cheek-swabbing is the preferred method for DNA collection.
Advantages for the client
The use of buccal swabs in paternity kits is non-invasive and a much easier technique for the collection of DNA samples. This means no needles for those of us who would rather not have blood taken with a needle, especially if it’s not absolutely necessary. The buccal swabs also don’t require refrigeration like blood samples do, and they are good for up to six months after the collection has been taken. DNA testing for paternity results can be an emotionally-difficult procedure, so using buccal swabs is one way to help make the process a little less stressful.
Advantages for the lab
Why do scientists prefer to use buccal swabs over blood samples? From the lab’s point of view,extracting the DNA for testing is a much simpler process when using buccal swabs as opposed to blood samples. When analyzing DNA for paternity testing, the polymerase chain reaction (PCR) method is used for both buccal swabs or blood, which means the results are the same for both. Brite Hub states “The tests used for identifying DNA in blood samples are the same as used for identification of DNA in mouth lining scrapings.” The only exception is for those who have been a recipient of bone marrow transplants recently. If you have received a bone marrow transplant, you’ll want to speak with the lab conducting the DNA testing before they process the samples.

Tricia says
When doing a DNA test does it matter if child gets swab and father does blood?
Identigene says
Hi Tricia,
No it will not matter both contain DNA that can be used for paternity testing. Thanks for your question!
Tyrefa says
But is it accurate if done this way?
HomeDNA Identigene says
Yes, absolutely, Tyrefa.
Justin says
What if chimerism is involved?
HomeDNA Identigene says
The chances of chimerism being a factor in a paternity test are infinitesimally small.
Tricia says
When reading the DNA results mother and child have one set of allele numbers father has two sets of numbers, why is that
Identigene says
Hi Tricia,
The reason for only having one allele value at a given location for the child or the mother is most likely because not enough DNA was collected or that the sample was a poor sample so both allele values were not found at the location. If we find that we do not have enough DNA to fully complete your test and come to a yes or a no conclusion, we will contact you for recollection of the samples in hopes of getting a more complete DNA profile or a better sample. If however, you did receive test results from us, enough DNA information was available to come to a conclusion for paternity. There is no need to be alarmed of missing allele numbers as it is somewhat common.
If you have any other questions regarding this or your test results, please contact us and we would be happy to help you! 1-888-404-GENE.
chris says
a Dna test was performed on my step son and his alledged father, and the results came back positive, the doctor. in turn states his son has sickle cell, but no sickle cell traits were found in the fathers genes. could the results be inaccurate due to the mother not being tested? just curious. because the dr states both the mother and father would need to have the sickle cell trait for the child to have sickle cell.
Meisha says
Good afternoon Chris. We apologize for the delay in responding to your question. The doctor is correct. Usually, both parents must carry the chromosomes for sickle cell anemia if the child has the disease. There have been reported cases of individuals with sickle cell disease who inherited two chromosomes from only one parent, but it’s very rare. (This is referred to as uniparental disomy; see Swensen JJ et al. Blood 2010 Oct 14; 116(15):2822-5.)
It’s also quite rare for a paternity test to be inaccurate, but the possibility increases if the mother is not included in the test and/or if two possible fathers are closely related. In this case, we recommend repeating the test with the biological mother and testing any other possible father to absolutely exclude him from paternity. Also, for peace of mind, we recommend using a third-party collector to ensure that no fraudulent activity occurs during the collection process.
al says
my friend wants to do a paternity test, but doesn’t want to tell the father until she has the results, can other samples be sent such as hair or toothbrush/razor blade??
Meisha says
The preferred DNA sample industry wide is a cheek cell. These samples are obtained by swabbing the inside of the cheek using a buccal swab that is provided in our testing kits. The cheek cell is the easiest sample to work with and any other type of sample is considered a special specimen. All special specimens require an additional lab fee of $400. We cannot guarantee that we will be able to produce results with a special specimen.
As far as testing without the alleged fathers knowledge, we cannot test any sample, even for a personal test, unless we have a consent signature for each of the participants being tested. As long as we have a consent signature that matches the name provided for each of the participants, and a legal guardian consent signature for anyone under the age of 18, we are authorized by you to test the samples that were sent in to us.
All special specimens need to be pre-approved by our lab and often times require a specialized collection kit to be sent to you. Please contact us 888-404-4363 for an approval and instructions on how to send the sample us.
I hope this information helps. If you have any additional questions or concerns, please feel free to contact us 888-404-4363 and we will be happy to assist you.
ernest says
Would there be any problem in the dna testing of a breast feeding baby using the buccal swabs?
Meisha says
Hello Ernest,
We suggest waiting at least one hour after eating, drinking, brushing teeth, or smoking before collecting the sample,s and this does include waiting one hour after breast feeding the baby as well. There is a possibility that the samples could become contaminated, but our lab would be able to detect this. We even detect if there are two different DNA samples on the same sample swab, as it will show two different DNA profiles. If samples are not contaminated our lab will be able to complete your testing and provide you with an accurate result. In the event that the samples are contaminated, we would offer a free recollection kit. I hope this information helps.
If you have any additional questions or concerns please feel free to contact us 888-404-4363 and we will be happy to assist you.
Nakisha says
If the father was chewing gum the whole time and spit it out right before he was swabbed, could the test results be correct.
Identigene says
Hi, Nakisha. Chewing gum doesn’t change DNA itself, but it could affect the quality of the sample. If you were issued a report, that means that his chewing gum didn’t affect the test one way or the other.
Ashley C says
I did a home DNA test for my daughter & alleged father. The results came back that he in fact was the father, which was SHOCKING…we’ve been using protection for the past 2yrs! My daughter looks nothing like him & in fact looks a lot like the other man which in fact we were not/never using protection. When I did the test I didn’t swab my (mother) mouth. So the test stated “motherless” ….could me (mother) not being apart of the test have anything to do with these results? I’m actually reconsidering another test…with me included this time!!!
Identigene says
Good afternoon Ashley, I apologize for the delayed response.
We do strongly recommend including a sample from the biological mother because there is a rare chance the results could come back inconclusive without her. However, testing the mother is optional and we do provide conclusive results on a regular basis when only testing the alleged father and the child.
The web link below will provide you with additional information about why the biological mother is sometimes needed to complete testing. I hope this information helps. If you have any additional questions or concerns please feel free to contact us 888-404-4363 and we will be happy to assist you.

jay says
I had a swab test done on my daughter and me and the supposed father but they came out negative so I was wondering if anything could of gone wrong because my baby was born exactly the same day as the due date the doctors gave me and the ultra sound the did showed that she was actually 2 days older than she was supposed to be also I was feeding the baby formula a few minutes before we went in to take the swab test. and I asked the supposed father if he would ratake the test but he said no!
Identigene says
We provide the most accurate testing available on the market today. We have worked extremely hard to put measures in place that prevent any mistakes from being made throughout the entire DNA testing process from beginning to end. This is why the accreditations we hold as a laboratory are so important.
Our goal is to provide an accurate, quality service to all of our customers. An extremely important part of the testing process is how the samples are handled and managed as they travel step by step through each stage of the testing. The strict standards and procedures we follow extend to every single part of the process from the moment the samples arrive at our laboratory to the release of the analysis report when the testing is completed.
If you are wanting to retest, we would recommend going through the legal DNA process. Legal DNA testing requires that all parties go to a designated collection facility so that a Chain of Custody can be established. Chain of Custody is the process used to maintain and document the chronological history of the samples (who has control of the samples at what time). At the collection facility, you will be asked to sign consent papers, designate an address where you want the results sent, and provide personal information such as photo identification. This process prevents anyone from being able to provide incorrect samples.
I hope this information helps. If you have any additional questions or concerns please feel free to contact us 888-404-4363 and we will be happy to assist you.

Betty says
Will You Guess Email Me The Results or Youll Just Email Me Notifying The Results Are In
How Many Days Does It Take For Me To Get My Results
Identigene says
Good afternoon Betty,
Due to our privacy policy we do not email results. You will be able to view and print your results from our website, or call us for results by phone. For online results: your username will be the entire email address on your case and the password is the results password you created.
Once the samples arrive to our lab it usually takes two full business days of testing depending on how the samples react in the lab. You will receive an email notification to inform you when your samples arrive and another once your results are available.
If you have any additional questions or concerns, please feel free to contact us 888-404-4363 and we will be happy to assist you.
jacky says
Hello I got the results yesterday for my daughter and her alleged father whom look so much alike! He did the test without telling me he has sent in samples the DNA conclusion came back negative he is not the father which I strongly believe the results are wrong. Could there be a chance that with blood work it would be more accurate because I have read that if you eat or smoke and then take a sample it could be that the results are wrong please help on best advice
Identigene says
Hi, Jacky! It is true that participants shouldn’t put anything in their mouths for 60 minutes prior to taking samples. If someone does put something in their mouth, however, it will not produce “wrong” results. What happens is the lab will catch that samples are contaminated or not good enough to test, and we will ask for new samples. Our testing is 100% accurate, meaning that for the two samples we compared, the results are reliable. That being said, in your case, the alleged father could have sent in anyone’s samples and claimed they were his own. The surest way to be positive the samples submitted are truly his is for all three of you to do the test together and send in the samples together. We don’t charge extra to test the mother too. Or you could have the alleged father and your daughter do a “legal paternity test,” whereby samples are collected and submitted by a third party. A legal paternity test is court-admissible. We wish you the best!
loatani watty says
The guy I had tested with my daughter is a heavy daily marijuana user and my daughter ate 30 mins before or less (I wasnt told she couldnt eat) will that give me wrong results?
cengerman says
Hi! The marijuana use doesn’t affect testing, no. As for your daughter, if there was any adverse effect on the quality of her samples due to eating in the hour before being swabbed, the lab will catch it and get hold of you to recollect samples. So eating or drinking will not affect results: the need for recollection just adds more time to the process. Hope this helps!
lj says
Ok chewing gum was eating 2mins b4 the test does this interfere with the results, when I asked the lady she said spit gum out & rinse with water…
Admin says
Hi there! Chewing gum won’t change the DNA itself, but eating or drinking anything for one hour prior to swabbing can affect the quality of the sample. If it does degrade the sample enough that extraction and testing isn’t possible, the lab will contact you and ask for a new sample. It won’t interfere with the results themselves. Hope this helps!
Angie says
Right before doing the swab my daughter’s alleged father drank some water. I didn’t think water would interfere with the collection of DNA, because the pamphlet wasn’t very clear about that. Will this make his sample insuffient if he had a few sips of water prior to collecting?
Also, it says not to lick the envelope and use tape, but I forgot and I licked the envelope, but realized and removed swabs and put them in another envelope (there was one extra). Should I be worried?
Admin says
Hi, Angie! I don’t think you used our test since our instructions don’t say anything about taping instead of licking the envelope. At any rate, if your DNA samples were degraded in any way by drinking water, the lab would let you know that they need new samples. The only concern is in the quality of the sample . . . drinking doesn’t change the DNA itself.
judy diedrich says
I had the DNA test done for three of us siblings. I was the link to both of my parents, the other two were in question if they were my full bio sibs. The test came back for the 3 of us index151 to 1, that we were Probability of Full-Sibling Relationships: 99.3%. I had heard so many ugly stories from my father about my mom and I wanted to know for me and my brother and sister, the truth. The lab tech on the phone was very helpful in explaining the results. When I told my father, he said that they were not right. Could this be true? I paid a lot of money to have this done and I know your company to be the best. He was almost hateful when I tried to show him the results. I just let it go, since it was not about him. So my question to you is 99.3% that we are all full siblings ship?
Admin says
Hi, Judy. 99.3% is a very strong probability for a full-sibling relationship. No doubt this is a very emotional issue for all parties affected, including your father. You can be sure the testing and analysis we did for your case was sound. If you want to discuss this in more detail, I highly recommend you contact us directly at 888-404-4363 and one of our experts will be happy to go over the numbers again with you. Thanks for choosing IDENTIGENE and for your kind words about our lab.
Kyla Burke says
I had my daughter and the alledged father tested for court, and I got the results back today and it said probability of 99.9%. I got the genex diagnostics one. Should I do another one? My daughter looks nothing like him and from what my ob says I got pregnant way before I got back with the alleged father, I’m freaking out. I need help please. I dont wanna get a blood test unless I really have to. Thanks
Admin says
Hi, Kyla. You did a court-ordered test, and so all DNA collections and submissions were witnessed by a disinterested third-party. You can absolutely trust these results. Physical looks are never proof paternity, and very often children look nothing like their parents. How they look is a product of many generations’ DNA input on both sides! As for what your OB said, I can’t explain that.
Ashanti says
Hello
I did a non invasive dna testing while pregnant of course and they swab my ex boyfriend mouth. The results came back as 99.9% as him being the father but of course we didn’t believe the results because my weeks doesn’t add up to him at all. I had sex with my other ex may 20th got on my period may 26th then had sex with my ex again on May 29th then we broke up and I met the “child father apparently” and we started having sex June 8th. Then got sick on June 9th, then found out I was 4 weeks pregnant June 27th then august 29th I was 13 weeks. It’s not adding up could the DNA test be wrong ? Or should I just wait for the baby to come ?
Admin says
Hi, Ashanti. Are any of the other men you had sex with biologically related to the man the test says is the father? Are they brothers perhaps? This could account for a false positive. If done by an accredited lab, these tests claim to be accurate; but if you have any doubts whatsoever, I would just wait for the baby to come at this point. It’s so much more affordable to test this way and the results are guaranteed if you test through IDENTIGENE.
Sammy says
I would really like some advice some 20 years ago myself and a sibling had a dna blood test done which came back stating that we where a certain percentage off the maximum dna that full blood sisters could possibly have so therefore we are full sisters. Recently we have done swab tests with the alleged father which has come back and says that he is my biological father but not my sisters. The swabs taken where not taken in each other’s company in fact we all reside in different countries…. yet when the blood examples myself and my sibling attended together could you please offer some guidance here as to how the results can show in one test we are full sisters yet the father is only to one of us. Thank you in advance
Admin says
Hi, Sammy. The results of a straight paternity test always trump those for a siblingship test, since the comparison of genes is much more straightforward. Plus, the technology is much better now than it was 20 years ago. Unless there is some reason why you think your sister might not have wanted to submit her own samples for testing this time and instead chose to fraudulently submit someone else’s, you can trust the newest results.
R. Mackety says
There are twins in the family and thru a dna testing one of the twins proved not to be of the same father. What are the odds of that? There were two testings done.
Admin says
I don’t know about odds, R., but it definitely happens. You can read more about it here: http://dnatesting.com/paternity-issues-twins-with-different-fathers/
R. Mackety says
anyone working today?
Admin says
Hi! No, we’re off till Monday.
Billy H says
Can a grandpa swab him self and swab his grandson for a DNA test
Identigene says
Hi, Billy! We can test a child with one or both paternal grandparents if the possible father is not available to test. We would also need the mother of the child to participate. Keep in mind that, if the child is a minor, consent from someone with legal authority to act on behalf of the child (most usually the mother) is required. Hope this helps!
Karan says
I had previously asked a similar question, waiting on a reply. But I didn’t think about the mother of the child, other than I know she has to give her consent. So are you saying for the test to be accurate the mother has to be tested also? Thank you!
Identigene says
Hi, Karan. No, the mother’s participation in the test itself is not generally needed to obtain conclusive results, but sometimes it is. That’s why we say it’s optional, but recommended. Since the mother’s participation is included in the lab fee, there’s no reason not to!
Shay says
I recently did a paternity test. I tested bothe alleged fathers. They are not related. However, they bothe came back positive. Is this possible? I know I did not mess up on the swabbing I was careful not to touch the end of the swab with anything. After I used a swab I immediately but them in the envelope one at a time as I was doing them. I made sure to be very cautious so I know I didn’t do anything wrong. Why did bothe of the tests come back positive?
Identigene says
Hi, Shay. What you describe is extremely unlikely in view of the fact that the men are unrelated. I suspect there was a mistake made during the collections process. I suggest you contact the lab you tested with and see what they advise you to do. Good luck!
Manny says
Mom to be and I took a paternity test (mom-blood/me-cheek swab) that came back negative while she was pregnant. Now that baby is born, she wants to take another. Could the first test be flawed?
Identigene says
Hi, Manny. Today’s Non-Invasive Prenatal Paternity Tests (NIPPs) are extremely accurate. If your test was done by an accredited, reputable lab, then you can trust results. That being said, if the mother wants to pay to test again and you’re OK with participating, then that’s an option. But it’s highly unlikely that the results would be any different. Our parent company, DNA Diagnostics Center, performs NIPPs and customers love this service.
Manny says
Turns out DDC conducted the test.
Manny says
DDC was the company that conduced the test. Are they reputable?
Identigene says
Hi, Manny. DDC is Identigene’s parent company. Identigene was purchased in December, 2016. DDC is highly accredited and is one of the largest private DNA labs in the world, processing thousands of paternity tests each year. Identigene is now DDC’s primary paternity brand. Hope this answers your questions!
Manny says
Will the test be different now that the test will be between child and myself?
Identigene says
No, the DNA profiles for both you and the baby cannot change, and so results for a post-birth test would be consistent with results for the pre-natal one.
Beverly Girl says
A lot of our family has had Ancestry DNA, I would like to get my mother’s DNA and my father’s brother DNA to explain more of my results. The three times I sent my mother’s in she was not able to produce enough saliva for a good test, so they wanted me to resubmit, I did twice more. My father is deceased by his brother is living. Is a buccal swab as acurate and saliva and do you have good results from people in their 80’s?
Identigene says
Hi, Beverly. Collecting DNA via buccal swabs is every bit as effective as spit, yes, and age of participants does not make a difference one way or the other.
J says
Can the DNA tell which is the dad when the two people who could be the father are father and son
Identigene says
Hi, J. The DNA test does not determine age…only gender.
Jenn says
I was not sleeping with anyone but one man at the time I got pregnant how did the result come out negative with my daughter and her father.
Identigene says
Hi, Jenn. Did you do a legal witnessed test or did you collect the samples yourself at home? Unless you watched the possible father swab his own cheeks and seal samples in the envelope, and then drop them off at the post office together, there is always a chance he could have submitted someone else’s DNA instead of his own.
Brendan says
Can a DNA test be done with just samples from child and father,,if so ow accurate are the results
Identigene says
Hi, Brendan. Yes, the majority of cases do not require the mother’s DNA in order to confirm or strengthen results, but sometimes her participation is needed.
Tyreese says
Can the sickle cell trait mutilate dna to cause a negative result to a paternity test ?
Identigene says
Hi, Tyreese. No, it doesn’t.
Rob says
My father is living in another country and I would like to have him take a test. The country is like a 3rd world country and I’m concerned that he may possibly have some one else swab their cheek (even at the professional clinic). Is there any way to verify the sample is really his? Would a blood test help in this situation?
Identigene says
Hi, Rob. All you need to do is order a legal paternity test instead of an at-home one. This way, your father will go to an approved DNA-collection facility in his country where they will witness DNA collection and submit the samples for testing. This prevents fraud such as what you describe, and no blood test is needed. I suggest you give our parent company, DDC, a call at 800-681-7162 and they can make all the arrangements for the test. Good luck!
Lovella says
I been with my bf on and off for 5 yrs. We’ve been trying to have a baby but the problem is when he broke up with me I had a one night stand.. When I fell pregnant by him I’m sure it was his.. I have a friend she told him that he wasn’t the dad and they hooked up.. And now his My ex bf bought a DNA kit from online he done the swab with out my consent and he put it on the mailbox..and the result came back that his not the father…my question how is that possible I only had a one night stand with someone… And now my daughter is 3 yrs old shes got abit of him the way she smiled it’s looks like him and she got light brown hair.. I’m Asian and his Australian… Pls help me what should I do.. Thank you
Identigene says
Hi, Lovella. You definitely need to test one or both men again and have the testing witnessed, to ensure there is no fraud. If you need to know who the father is for child-support or custody, you will need to get a legal test. It’s not an at-home test. You can find out more about it here: https://dnatesting.com/how-the-paternity-test-kit-works/paternity-test-for-child-support/
Nikeysha says
Hello I am due September 20th, 2017 and I want to get a DNA test done for my new baby and the alleged father. Do you know if Sinai Grace hospital do paternity tests there?
Identigene says
Hi, Nikeysha. You’d need to call them directly and ask. If not, you can get our kits at Walmart, CVS, or Rite-Aid!
Stan says
I drank coffee before I did my test should I take the test again?
There are a few blanks spaces on the line should I be concerned?
Identigene says
Hi, Stan. I’m not sure what you mean be “a few blank spaces.” As for drinking coffee: Eating or drinking prior to swabbing your cheek won’t change your DNA, but it can sometimes affect the quality of the sample, making it difficult or impossible to extract enough DNA for testing. Since you were issued a results report, this wasn’t a problem in your case.
Princess says
My doughter did test with the alleged father the results come 52,87%then I tested they come negative and they look alike and I didn’t sleep with any guy for 9months till I give back is this happening
Identigene says
Hi, Princess. Your question is a bit confusing. Are you saying the probability of paternity for a test was 52.87%? If so, those results are inconclusive. Most accredited labs do not issue results like that. It’s either 99% (or higher), or 0%. Is it possible he submitted someone else’s DNA instead of his own? Something to consider.
Londy says
Hi I took a sample with the allegedly father and the result came back negative. We three of us baby , allegedly father and a mothers went to the lab and take sample in where everyone was watching and put it on the sealed anvelop and we signed. Is there any possibility that the result was wrong. As I want to do a blood sample to prove to him again. Please advise can blood samples give different results in this case
Thanks Londy
Identigene says
Hi, Londy. If the exact same people who tested the first time test again the second time (this time with blood samples), the results will be exactly the same. The quality of a DNA sample taken with a cheek swab is every bit as good as one taken with a blood sample.
Mindy says
Hi.. i had prenatal paternity test few months ago which i provide blood test and the alleged father buccal swab.. the result come up that he is the biological for the probability of 99.9%. But im afraid the swab is not as accurate as the blood test. Do i need to provide my other partner sample to make sure or its all clear since the result is 99.9%?
Identigene says
Hi, Mindy. DNA from a buccal swab is every bit as good as DNA from a blood sample. The result you were given is as conclusive as it gets for a positive paternity result!
Mindy says
Thanks for your reply. Im sure i had my test with the leading lab (easydna and DDC) but i just want to be really sure. So do you mean if the the alleged father come up with the probability of 99.9% i dont need to do the dna test with my other partner??
Identigene says
That is correct. You have your answer!
Halfpint says
If you want to drop my last name that is fine. I thought I was supposed to put my whole name. There is no case technically, We do not nor do we plan at this time to go to court for visitation or to have the paternity test, the child’s mother is remarried, the mother and my stepson’s mother is really good friends, she knows the mom suspects that is her grandbaby. She will consent to the test because she has already told her ex husband he was paying child support for one kid that wasn’t his. He has a newborn with new wife. He has nothing to do with 2 daughters with 1st wife.
Latasha says
Hello….I did a test back in 2014 and the collection date of the alleged father wasn’t on there, but I know they was all sent at the same time, but not arguing the results (Dodged a bulled)….my question is….
If the alleged father have the HPV virus will that affect the results? My child and I do not have the virus…..
Identigene says
Hi, Latasha. No, that wouldn’t affect results one way or the other.
Robert says
My wife had an affair during or marriage with my second cousin. We had a baby whom i took the swab for. The results were 99.9% as being mine. Could there still be a chance the baby could be my cousins?
Identigene says
Hi, Robert. No. You don’t share nearly enough DNA with a second cousin to make it an issue. You’re the father!
Sandra says
If the DNA test shows one possible mutation was observed on the alleged father, is additional testing recommended?
Identigene says
Hi, Sandra. Mutations are taken into account when calculating probability of paternity, and if additional markers need to be analyzed in order to determine probability one way or the other, the lab does just that.
Ashley says
I only was with one man the time of conceiving and the time of conceiving was march 12th and my doctor confrimed it as well and my due date was Dec 3rd which all ultra sounds say the same but i was a high risk due to me taking steroids will the steriods affect test i have read it does
Identigene says
Hi, Ashley. The only things that could affect paternity-test results are if a participant received a recent blood transfusion or if they ever had a bone-marrow transplant. Steroids don’t affect a paternity test.
tammyt says
My son is EC I am AC and his father is AA with results from sicklecell testing….i am of indian decent and our bloodline is confusing…..is he the father?
Identigene says
Hi, Tammy. We are experts in DNA and so this is not the best place to answer that particular question.
Princess2 says
I’d like to get a prenatal paternity test done, who are the reputable companies and who are the dodgy companies
Identigene says
Hi, Princess. Beware of companies that offer tests at super-low prices. Chances are good they are not an accredited laboratory. I can only vouch for the test provided by Identigene’s parent company, DDC (DNA Diagnostics Center). It’s the only test that’s been validated and published. You can learn more about it here: https://dnacenter.com/dna-paternity-test/non-invasive-prenatal-paternity-test/
Christina says
Hi i wonder if it possible to have a DNa sample at home . My father of my son want me to send swab sample in his country because he is not sure if it is his son. Is it okay to send to other country a sample and not be contaminated?
Identigene says
What country is it, Christina? Is he not willing to send his sample here to the U.S?
Gloria says
My daughter got a swab test done and it came back 99.9999995% does that mean he is her father and is it accurate and if she gets a blood test done will it come out the same ?
Gloria says
He still clams that she isn’t his and I want to know from a doctor that she is his
HomeDNA Identigene says
Hi, Gloria. Yes, as long as the samples submitted are from the same exact people, then results would be the same whether cheek swabs were used or a blood sample. Your results is very conclusive that the man tested IS the biological father.
David says
Hi, I just had a paternity test done by a swab. it came back no possibility of being the biological father, there was also no combinations of alleles either.
The said mother is refusing to accept this result and is asking for a blood test stating this is the best and only test she will believe in even suggesting that I had paid for the negative result.
Is a blood test more accurate than a swab
HomeDNA Identigene says
Quite simply, nope. DNA is DNA, no matter from where the sample is obtained.
Jonie says
I’m curious about how accurate the swab would be using the baby, and the alleged fathers mother. My son is deceased and because I’m his mother I’ve been asked to do the swab so we can know if the baby is indeed my son’s. Your thoughts on this??
HomeDNA Identigene says
Hello, Jonie. My condolences on the loss of your son. We do grandparent testing all the time when the alleged father isn’t available for testing. It is an extremely accurate alternative, especially if the mother of the child also contributes her DNA for testing.
Rayna says
My daughter has thrush and was born with jaundice. Will this affect the results of her paternity test?
HomeDNA Identigene says
Hi, Rayna. Those conditions wouldn’t change her DNA, but they could affect the quality of the samples collected on the swabs. I suggest you wait till the thrush is past before testing, if possible.
Gabriel Lillian says
I am happy with this information. Thanks!

Hi there,
I have a friend that did a Swab test for paternity. It came back 0%.. He still believes the child is his. Now they are doing a Blood DNA test. Will they receive a different outcome in the results?
HomeDNA Identigene says
Hi, Katy. If the DNA for the exact same people is submitted, the results are going to be exactly the same as the first test. DNA is the same, whether it’s collected with a swab or with a blood sample.
PRECIOUS says
Is it possible for a child to turn out to be the biological son of an alleged father( who is not the father but want to claim the child by all means)he then mixes his dna samples with that of the child( by swabbing his mouth with the same swab he used for d child in collecting samples in order to make it look like his when tested) and presents as the child’s sample and then collect another separate sample for himself and presents as his… to be compared with the one presents as his child’s . Is it possible for the result to present him as the father that way?
HomeDNA Identigene says
No, it isn’t.
Robbins says
If the alleged father mistakenly touched the swab that was used in collecting the samples of dna from from the child, will the father dna mix with child’s like that, will it alters the child’s dna and makes the result presents the child as the biological child of the alleged father even when he’s not the actual father?
HomeDNA Identigene says
Hi, Robbins. The lab easily detects if there are two DNA profiles on a swab. If the swab were contaminated by the touch, then the lab would stop testing and request new samples without issuing results. So no worries!
Lavender says
When we check our online results to make sure results are legal and truthful would there be a watermark or signature at the bottom of the results Most of the dna test that I looked up all have a signature at the bottom and a watermark Like how do I know someone didnt scam him and just putting down anything on the result papers
HomeDNA Identigene says
Hi, Lavender. There are only signatures on legal tests, since the identities of participants cannot be independently verified. The case number is on the report. If you accessed your results through our secure online portal, you can be sure they’re legit.
