“Uh oh. Did I mess up my Paternity Test?”
Getting a paternity test today is much simpler and more affordable than ever, thanks to top-quality, home kits you can purchase easily and affordably at your local retailer. Because answers have a critical impact on a child’s and family’s lives, it’s important that you choose a highly-accredited DNA laboratory to perform the testing. When a paternity test is ordered, you and the lab form a partnership, and each party has a responsibility to ensure DNA samples are handled properly.
As a participant in the test, your job is to make sure samples arrive at the lab in good condition. To get samples, participants collect DNA with cheek swabs. It’s painless and fast, and the process itself isn’t hard at all, but you have to do it with care to maintain the integrity of the DNA. Here are five surprising ways paternity test samples can get contaminated.
Paternity Test Problem #1: Eating, Drinking, Smoking, etc.
Avoid putting anything in your mouth for at least an hour prior to collecting cheek-cell samples. Foreign particles from food, liquids, toothpaste and tobacco byproducts don’t alter the DNA but they can mask it. The consequence is that the sample becomes degraded and therefore unusable for paternity testing. Even babies being tested shouldn’t nurse or have a bottle prior to testing.
The good news: This mistake doesn’t adversely affect your results because the lab always catches this problem and suspends testing immediately. You’ll simply be asked to do a re-collection at no charge, and then testing can resume.
The bad news: You have to wait longer for your results due to the need for re-collection.
How to prevent it: Follow this guideline precisely. If a participant eats or drinks within the hour before collection, simply wait a little longer before testing.
Paternity Test Problem #2: Spitting on Swabs Instead of Swabbing Cheek Cells
With the new popularity of some ancestry tests, it’s easy for paternity customers to get confused between collecting cheek cells and collecting spit, or saliva. The two types of samples are definitely not interchangeable. Robots for relationship testing are designed to extract DNA from cheek cells, and cheek cells provide a more concentrated amount of high-quality DNA.
The good news: There is a chance that the robots and laboratory technicians might still be able to extract DNA for testing.
The bad news: If the samples are contaminated or if the lab is unable to extract enough DNA, you have to wait longer for your results due to the need for re-collection.
How to prevent it: Read directions very carefully and be sure to collect cells from the inside of the cheeks only, avoiding the gum areas as much as possible. And do not spit on the swabs!
Paternity Test Problem #3: Cross-contamination
When you’re handling swabs, it’s critical to maintain the integrity of each swab from start to finish. What does that mean?
Be sure not to:
- Handle the tips of the swab, especially if you are swabbing someone else
- Drop the swab
- Accidentally put swabs from two different people in the same envelope
The good news: These kinds of mistakes are caught at the lab level and won’t affect your results.
The bad news: You may have to wait longer for your results if re-collection is necessary.
How to prevent it: Handle swabs with care and be sure to use separate sample envelopes for each participant.
Paternity Test Problem #4: Some Medical Procedures
The following scenarios can definitely have an effect on paternity testing results:
- A participant has recently had a blood transfusion
- A participant has ever had a bone marrow transplant
In both scenarios, someone else’s DNA has been introduced into a participant’s body and can remain there, either temporarily or for long periods of time. When the paternity testing sample DNA from that participant is amplified in the lab, technicians may see two separate profiles from that one individual.
The good news: Even if you or another participant has had one of these procedures, it is still possible to get conclusive results.
The bad news: It may not be possible to get conclusive results.
How to prevent it: You can’t change the medical procedure you’ve had, of course, but you can let the lab know about it in the submission form. This way, if the lab determines the medical history may be affecting results, you can be notified.
Paternity Test Problem #5: Re-using Packaging
Buccal (cheek) swabs are specially-created for DNA collection and they come sealed in plastic packaging to keep them sterile. While this packaging is perfect for unused buccal swabs, it causes problems for swabs once they’ve been used to collect DNA. Here’s why:
A DNA sample contains cheek cells which are inevitably mixed with some saliva. When you put a wet swab back in the plastic packaging, the sample can no longer ‘breathe,’ and mold nearly immediately starts growing. This mold can degrade or destroy the DNA on the swab so much that the DNA can’t be extracted and tested.
The good news: The lab will catch this problem and ask for re-collection, so it won’t affect your results.
The bad news: You have to wait longer for your results due to the need for re-collection.
How to prevent it: As you collect samples, be sure to place swabs in the paper envelopes provided as noted in the kit instructions, and not back in the plastic packaging. Easy!
Paternity Test Problem #6: Mailing Wet Envelopes
As mentioned earlier, the swabs pick up cheek cells, but also some saliva too. As a result, it’s not unusual for the paper envelopes containing samples to get a little wet. If envelopes are mailed while still damp, they can rip while en route to the lab. This contaminates all samples, unfortunately.
The good news: DNA samples can be collected again using new materials.
The bad news: You have to wait longer for your results.
How to prevent it: It’s best to air-dry swabs as much as possible by holding them by the handles for a little while before placing them in the paper envelopes. But if an envelope gets a little wet anyway, just lay it on a clean counter and allow to air-dry at room temperature before mailing.
The Bottom Line
Our customers often reach out to us after their results are issued and ask, “The swabs were wet and I put them in the envelope anyway. Did that affect results?” Or, “My baby breastfed right before I swabbed him. Could that change the results?” No worries! Contaminated samples cannot “change” results, because the lab always catches the problem and asks for new samples before results are issued. But it is an inconvenience to you because you have to wait longer to get results. Be sure to carefully follow all instructions that come with your paternity testing kit. This prevents any hold-ups in the process and helps you get your results as soon as possible.

Jenny says
Could the swabs have become cross contaminated if swabs were placed in envelope wet with saliva?
Could my results come back false positive/negative?
Admin says
Hi, Jenny. If samples are degraded or compromised in any way, the lab would ask for new samples. It’s an inconvenience for the customer because you have to wait longer to get your results due to the need for a recollection, but it won’t affect actual results.
Jenny says
Okay so what if the saliva from one envelope transferred to another envelope? Could that compromise the results of the test?
Admin says
It shouldn’t affect results because the lab would detect two DNA profiles in one sample and ask for a recollection. There shouldn’t be too much saliva in the envelopes anyway. When done correctly, the swabs gather cheek cells with a minimum amount of saliva. If they’re quite wet, we advise waving the swabs in the air to dry them a bit before placing in the envelopes.
denise bennett says
If some one used mouth wash before a DNA would it come out wrong
Identigene says
Hi, Denise. Eating, drinking, or using mouthwash for an hour prior to swabbing doesn’t change DNA (and therefore the outcome of the test), but it can affect the quality of the sample. If the DNA sample was contaminated from it, then the lab would ask for new samples before issuing results.
Alora says
I did the mouth swabs for my, my daughter, and the potential father but I did not air dry I stuck them directly into the envelope. Will the swabs still work? They are already mailed out
HomeDNA Identigene says
Hi, Alora. They’ll probably be just fine. If somehow they got contaminated, the lab would suspend testing and we’d send you new DNA-collection supplies free of charge so you can send in fresh samples. If results are issued, then the swabs were just fine.
bob says
If the sample is contaminated do yous get any dna from it or keep the results?
Admin says
Hi, Bob. If a sample is contaminated, we don’t run the test in the first place. The sample is discarded and we ask for a new sample from the customer.
Tione says
Would I be able to dip the swab inside my saliva instead of swabbing my cheek
Admin says
Hi, Tione. I’m sorry, but no. Our testing robots are designed to extract cheek cells and not saliva. Cheek cells give us a higher-quality sample for the type of testing we do.
T says
I dont think I swabbed the cheeks hard enough to get check cells it was more saliva so this would hurt my test results
HomeDNA Identigene says
Hi, T. If there wasn’t enough DNA on the swabs to complete testing, the lab will send a notification via email or text. If you are issued results, then there was no problem.
Tonya says
What happens If you want to get a dna test done on an alleged father and child and mother provides dna as well but all three live in different states how would you go about getting the test done?
Admin says
Hi, Tonya. There are several different ways. Give us a call at 888-404-4363 and one of our experts will be happy to explain your options. Thanks!
Rotunda says
If the alleged father eats a popsicle right before the test and my 2 week old baby had a bottle right before the test will u still get the right results…or can it mask the test?
Admin says
Hi there! Eating or drinking right before swabbing won’t alter the DNA, but it can degrade the sample, making it difficult or impossible to test. That’s why instructions say to not put anything in your mouth for an hour prior to collecting DNA. If there’s any problem with the DNA samples, the lab will let you know and ask for new samples before they proceed with testing; so it won’t affect your test results.
Jessica says
I swabbed my sons mouth right after his bottle i didnt know not to do this would there be a chance the formula messed with it or us there a chance the dna could be wrong? Please help me.
Identigene says
Hi, Jessica. Drinking a bottle can’t change his DNA, but it could affect the quality of the DNA sample collected. This is why we ask that participants not eat or drink for an hour prior to swabbing. Were you issued a results report? You didn’t mention where you’re at in the testing process. If you are issued a report, then your son’s samples were good enough for the lab to extract the DNA. If the swabs are too contaminated by his drinking the bottle, then the lab suspends testing and asks for new samples. Either way, the actual results aren’t affected or changed. Hope this helps!
Kemar says
If a person had a blood transfusion as a baby can it alter a paternity test when that child becomes an adult?
Admin says
Hi, Kemar. No…the effects of a blood transfusion on a person’s DNA is temporary. However, it’s always wise to inform the lab about it when doing a paternity test.
Mark McDaniel says
Is it possible for your company to get a DNA sample from a subject’s toothbrush?
Admin says
Hi, Mark. Is it possible? Absolutely. Do we do it? Only in the rarest circumstances, and it’s very expensive for the customer. Is there a reason why you want to use a toothbrush and not a cheek swab?
Ivan Baros Sr. says
My father has Alzheimer’s and wanted a DNA test for genealogy results and ordered a test hoping for a cheek swab test but got a spit test! When I took it to my father he couldn’t comprehend spit, spit….he just kept sticking his tongue into the funnel and tube! After a few minutes I just took the test away from him but saw a few drops of saliva in the funnel so I rinsed the funnel into the sterile container the tube came in with the stabilizer, then poured back into the tube and shook well! Do you think there will be enough saliva for a good DNA test?
Admin says
Hi, Ivan. I suggest you contact the lab that is doing the testing for you and get their input. For our paternity tests and other family relationship testing, we use cheek cells collected from cheek swabs and not spit, so this is not our area of expertise. I’m sorry about your dad…I know Alzheimer’s is so tough on family members and caretakers. Wishing you all the best!
Megan says
Can u get enough for a dna test from a soda bottle, or glass?
Admin says
Hi, Megan. Extracting DNA from those items is only a technique that’s used in crime-fighting. It’s not used in paternity testing. For a paternity test, a cheek-swab sample is required, as is signed consent from all participants. Hope this helps!
Angela says
If mold destroys DNA from putting it back in the plastic package, why would they send a zero percent DNA result?
Admin says
Hi, Angela. If the quality of the DNA sample is not compromised, then the lab will go ahead and issue results. If the contamination is too severe to extract a good DNA sample, then the lab asks for a fresh sample.
gigi says
i already done paternity test of my four kids the result is 99.9999 % but one of my children eat icing cake before testing and i saw the is color pink due to icing cake … but the result is 99% …is that right?
Admin says
Hi, Gigi. Eating prior to testing doesn’t change the DNA; it may only affect the quality of the sample. If the icing was bad enough that it affected the sample, the lab would not have issued results and would instead have asked for new samples. So you’re good!
Judy says
When swabbing for dna if the child grabs the swab in her hand Can that affect dna?
Admin says
Hi, Judy! It can affect the quality of the sample, sure. Was it her own swab? If it was someone else’s swab, I would just discard it. This is why we have all participants do three cheek swabs. That way, if one is contaminated, there are still two others to test with. Hope this helps!
Judy says
It was the child’s dna swab so hopefully it won’t affect it.
Admin says
Yes. If it’s a problem, the lab will let you know.
Mona says
Hi I breastfed my child right before doing the DNA swab and I didn’t know I wasn’t supposed too. It was the only way I would be able to do it with her participation. Would that alter the results?
Admin says
Hi, Mona. Eating or drinking before swabbing doesn’t change DNA, but it can affect the quality of the sample. This is why we recommend not eating, drinking, or smoking for one hour prior to swabbing. If the breast milk residue ended up contaminating the sample so much that the lab can’t extract the right amount of DNA, testing will stop and they will ask for a new sample from you. If your test goes smoothly and you get a results report, then breastfeeding didn’t end up being a factor after all.
Tara says
My son is 2 months old. At birth he became very sick and was on ECMO Life Support for 12 days. He received MANY blood products on a consistent basis during those 12 days. As I said he is 2 months old now and he is home from NICU. I want to get paternity test but I’m wondering if all of those blood transfusions are going to alter or affect results?
Admin says
Hi, Tara. So glad your baby’s OK! It’s definitely too soon after multiple blood transfusions to get a paternity test done. Some studies have shown that donor DNA can still be present 18 months after a transfusion. I highly recommend that you consult with a physician before testing.
Olive says
How do I know if the paper the the father gave was from us taking the test or the other lady he took the test with as well
Admin says
Did you test with us? If so, there should be names on the test results.
Kay says
Why aren’t the names on the results?
HomeDNA Identigene says
Hi, Kay. Names are not put on results because we cannot verify if the samples provided really belong to who participants say they do. However, if you chose to do a legal, witnessed test with court-admissible results, then names are put on the report, since the identities of all participants are verified independently. We do put each participant’s role in the test on the report for at-home tests.
TM says
Hi My sister took her toddler to get a DNA test. The guy had been supporting the child for 2 and a half years. The test came back that he was not the father. My sister states that because my niece was drinking ice tea right before they tested that the facility informed her most likely it would come back negative. But this does not make any sense to me so I was just curious if that is possible? My sister also stayed that the alleged father had been tested at a separate facility like a month later both were done in florida. The alleged father immediately stopped paying for the child and cut her out of his life. The sad part is no matter what my niece is the one getting hurt. So what do you think?
Identigene says
Hi, TM. Drinking iced tea won’t change DNA and affect results of a test that way. What drinking before swabbing can do, however, is affect the quality of the DNA sample, making the sample unfit to test. If that had been the case, then the lab would simply have asked for a new sample and not issued results. Your sister can trust the results if DNA collection and testing was performed at an AABB-accredited facility.
TEENB says
THE ORIGINAL UNUSED SWABS CAME IN A PAPER SEAL NOT PLASTIC AND THE AFTER SWAB WAS TAKEN I DID INSERT THEM BACK INTO THE PAPER, THEN PLACED THEM IN THE ENVELOPE LABELED FOR FATHER AND REPEATED STEP FOR BABY, CAN I STILL GET RESULTS ACCURAELTY EVEN THOUGH SWABS WERE PLACED BACK INTO THE ORIGINAL PAPER SEAL? MOST CASES I’VE READ INDICATED THE ORIGINAL SEAL WAS PLASTIC BUT MINE WAS PAPER
Identigene says
Hi. If there’s a problem with your swabs, testing is suspended and the lab will call you and ask for new samples. No worries!
Jeanna Jozaitis says
Found a possible male cousin that had been given up for adoption. Will a niece or nephew of the supposed father be good enough for comparison with him?
Identigene says
Hi, Jeanna! That’s probably not a close enough relationship for testing, but I suggest you contact us directly at 888-404-4363 to consult with one of our relationship-testing experts.
Diana says
My husband thinks that his chewing gum was use to fake a DNA TEST can it really happened. He says he saw the child mother pick up the gum he spits out and put it on the child mouth.
Identigene says
Hi, Diana. The answer to your question is no. DNA technology is so sophisticated now that if a swab somehow contains more than one person’s profile, the lab will catch it immediately, suspend testing, and ask for new DNA samples before issuing a report.
Carol says
Can a person who has been drinking alcohol before testing affect the test.
Identigene says
Hi, Carol. We tell people not to drink or eat anything for one hour prior to testing. This could be milk or it could be water or alcohol; the principle’s the same: Eating or drinking just prior to swabbing cheeks could compromise the quality of the DNA sample. It won’t change DNA, but the robots may not be able to extract the DNA from the swabs as efficiently. It the quality of the samples isn’t good enough for testing, the lab will simply ask for new samples before results are posted.
Abriel says
I only have two swaps in each envolop. It required four but we didn’t read the directions carefully. Will you still test the samples?
Identigene says
Hi, Abriel. If more DNA is needed, we’ll reach out to you.
luslec says
Hello! I just want to know if how accurate DNA test? so if i have 99.9% that am the father should i not worry anymore? or do i need to take 2-3 more test. is it possible that the result will change if i take another test? pls answer :(
Identigene says
Hi, Luslec. What an excellent question! If you test with an accredited, highly-regarded DNA lab, you can absolutely trust your results. If you got 99.9% probability of paternity, then you are considered the biological father of the child. The results are based on probability and can therefore never be 100% unless the lab also tested every single man of your ethnic background in the world. But your result is about as close as it gets and would stand up in any court of law. DNA does not change from test to test. Hope this helps!
Janet says
Hi Diana, I put wet swab in paper envelope then try to move them around with my finger tips would my Dna get in true the wet envelope and affect the swab?
Identigene says
Hi, Janet. Most likely it didn’t affect the swab. However, if the lab does determine that the swab was somehow contaminated, they would suspend testing and ask for new samples. So it wouldn’t affect results.
JayJay says
I licked the envelope to seal the DNA samples, but on the mailing envelope it says to use the tape to seal DNA sample envelopes and not to lick. Will that affect my test?
Identigene says
Hi, JayJay. You should be just fine. If there are any problems with the quality of the DNA samples, we would suspend testing and contact you immediately for new samples.
Viole says
Hello! is DNA test is really credible? what if i get a result with 99% does it not really need to take another test, is 1 test is enough? whats bothering me is false positive result. can you tell me if its possible to false positive occur when only 1 alleged father and 1 child tested? sorry for many question. Thanks!!
Identigene says
Hi, Viole. Because a paternity-test result is obtained based on statistics and probability of paternity based on ethnic background, it’s impossible to get a 100% result unless all men of the same ethnic background were also tested. So 99% or higher probability of paternity can be trusted. As for getting a “false positive,” that can really only happen if there is another possible father (other than the man being tested) who is a close biological relative of the man tested (brother, father, etc.).
Nicole Callahan says
How long does it take for an email of receipt after DDC receives samples. I live in Va. it shouldn’t take this long for the samples to arrive in Ohio. Its been over a week.
Identigene says
Hi, Nicole. If you used the postage-paid envelope included in the kit, then it can take 7-10 business days for samples to arrive at our lab.
JayJay says
I sent my DNA samples on March 10th, I know it should take 7-10 business days for the lab to receive them. How long should it approximately take to receive the results?
Identigene says
Hi, Jay. In most cases, results are posted to your secure account in two (2) business days. If you pay for express results, then they’re posted the next business day after samples arrive at the lab. In some instances, additional testing is needed in order to get conclusive results, which can take a few additional days.
Logan Hammond says
I have a question could a preemie baby born at 30 weeks on oxygen and with a feeding tube in his mouth who just got breast milk and we did the swab could it give a false negative, and he is a twin we did not test the twin for the smile fact they are identical.
Identigene says
Hi, Logan. If there are any problems with the samples being contaminated, testing is suspended until the lab can get new samples from participants. A test-report is never issued that was conducted with contaminated DNA, so no worries. All the best to you and the babies!
Candy says
Hi I am the paternal grandmother and my husband and I want to do a DNA test on our supposebly grandchild can you use us my son is incarcerated but really want this answer?
Identigene says
Hi, Candy. It’s ideal of both you and your husband can test with the child. To optimize the chances of obtaining conclusive results, the mother of the child should also participate. You are welcome to contact our parent company, DDC, directly at 800-681-7162 to speak with one of our experts about your options as well as pricing.

Justine says
The father bought the test but the packing he had only had three swap one for each person will that still be good enough for testing
Identigene says
Hi, Justine. I suggest you call us at 888-404-4363 and we’ll send more out to him free of charge.
Amy says
Hello,
My friend wanted to have his son tested so he bought your product he swabbed his self and I swabbed his son. He is concerned that the result is wrong because I swabbed him and basically is worried my DNA altered the test. I was very careful only touching the stick. I never came in contact with the swab part. Then I placed them in the envelope like the instructions said. Now if my DNA contaminated it in anyway your lab would have shown 3 different dna’s right? Or would the lab have contacted him?
Identigene says
Hi, Amy. Yes, the lab would have caught that there was also a female profile on the male child’s swab, had there been any contamination. Since your friend was issued a report, that wasn’t an issue. So you can trust the results!
Larry collins says
i had a dna paternity test done with what i believe was my son it came back o match found and was excluded, my question is me having had radiation treatments and chemo therapy for throat cancer could have effected the results?
Identigene says
Hi, Larry. The short answer to your question is “no.” In most cases, only blood/plasma transfusions or bone-marrow transplants can affected paternity tsting, as explained in this article. That’s because with those two procedures, someone else’s DNA was introduced into the tested party’s system. This is not the case with the cancer treatments you had. I sincerely hope your health is on the mend. And remember, you don’t have to have the same DNA as your son to be a dad to him, if that’s what you want.
DELLA M HALL says
My father, who passed away almost 3 years ago, has what is believed to be a daughter with a woman he dated before my mom. Her mom has stated there’s a possibility of another man being the father, who is also passed, but she’s confident that my Dad is the father. Can a paternity test be done using my DNA for comparison?
Identigene says
Hi, Della. Yes, we can do what’s called a “half-sibling vs. unrelated” test where we answer the question of whether or not you have a half-sister, or whether the woman in question is not biologically related to you. In order to get the most conclusive results, it would be ideal to have both your mothers participate also, if it’s possible and they’re willing. You are welcome to contact our parent company DDC directly to discuss the options with one of our specialists: 800-681-7162.
Confused results says
Hi is it possible for the alleged father to swab someone else mouth and the results come back negative? Even with his name. ( Alleged father) being on the paper? would the lab be able to tell the difference?
Identigene says
Hi! For an at-home paternity test, all participants should witness each other’s DNA collection, seal the envelopes as a group, and drop samples at the post office together. If not, and you have reason to suspect the possible father might commit fraud, it’s possible that he submitted someone else’s samples as his own. The lab cannot tell if a sample belongs to the man whose name is on the paperwork or not. All the lab can tell is if the participant is male. If you have reason to suspect fraud, I highly recommend that you perform what’s called a “legal paternity test.” This type of test works the same at the lab level…the only difference is that DNA sample collection and submission is supervised by an approved third-party witness to make sure all participants are who they say they are. We do thousands of these tests every year…just give us a call for more info or to set up the test: 800-344-9583.
Anonymous says
If either parent is a chimaera, would that affect the DNA results?
Identigene says
Hi! Yes, it definitely could. However, the chances of that happening are extremely unlikely.
Rell says
Can only the potential father and child be swabbed, or is it a MUST that the mother be swabbed as well?
Identigene says
Hi, Rell. In the overwhelming number of cases, the potential father’s and the child’s DNA are enough to get conclusive results. However, there are times when the mother’s is needed to strengthen results, and this is why her participation is recommended but not required. If her DNA is needed, the test is suspended until the lab can get her sample, which can be inconvenient to the customer because of the additional wait time. So for this reason we include enough testing materials in the kit for mom as well and testing her samples is included in the lab fee.
Ashley says
If u doctor gave u conceive date and u only been with only one person and it all adds up but dna test came back 0% and also can taking steroids awhile pregnant effect test
Identigene says
Taking steroids while pregnant won’t affect DNA results. Was your test a legal, witnessed one? If it was a home test, is there a chance the alleged father sent in someone else’s swabs instead of his own? These are some things to think about.
Renae Lusk says
My fiance and I got a DNA test on a child his ex claims is his. However we caught her taking the used swabs from the child and swabbing her mouth and spitting on them. Will that affect the test results
Identigene says
Hi, Renae. If there are two DNA profiles on one swab, then the lab suspends testing and asks for new samples. If you suspect she is likely to commit fraud (and it sounds like she may be), then you may want to consider paying a little extra to get a legal, court-admissible test done. This way, all aspects of DNA collection are witnessed and no tampering can take place. You can learn more about it here: https://dnatesting.com/legal-dna-testing/
Lynn Johnson says
If my daughter was taking amoxicillin for a severe tooth infection, can the antibiotic or the infection affect the DNA results. The amoxicillin pharmacy detail sheet indicated that the medicine can affect some lab results.
Identigene says
Hi, Lynn. The medicine won’t change her DNA, but it could affect the quality of the DNA sample submitted. Did you get a results report back? If so, then DNA was able to be effectively extracted from her sample. If the medicine had contaminated the samples, the lab would have requested new ones.
Greg says
If the father added his blood to the mothers would it show him being the father of the child, or would it show up as contaminated supplies?
Identigene says
Hi, Greg. It would be a contaminated sample.
tyler says
can a sample from dad be frozen until baby gets here ??
Identigene says
Hi, Tyler. No, they shouldn’t be frozen. Put sample swabs in a paper envelope and keep them in the refrigerator.
Ronda says
Hi,
My daughter is a heroin addict and had my granddaughter 4 yrs ago with a man of mixed race(black & white). We are purely white.We felt she was claiming him as the father to obtain child support, and the fact her real bf is also a heavy drug user, in & out of jail etc, and could never pay child support.
This child looks NOTHING like the man my daughter claims is the father. I persuaded him to do a DNA test with my granddaughter. It was 99.9 positive.
The issue is, my granddaughter looks identical to my daughters real bf, the drug user. Same hair, same blue eyes, same stature, same nose, same lily white skin. It’s like a mirror image.
Is it possible due to the other man being of mixed race, there could be any reasons the test is inaccurate?
Thank You
Identigene says
Hi, Ronda. Looks are never a positive proof of paternity. Genetics are interesting, and different gene mixtures inherited can produce unexpected physical characteristics sometimes: Seeing as the mixed-race man who was tested has white in his background, it may very simply be that your granddaughter displays more of the genes that code for white skin. When doing analysis for a paternity test, the statistics performed to determine the probability of paternity take into account the possible father’s ethnic background. There is no way to produce a conclusion for 99.9% probability of paternity unless the man tested really is the biological father. So from what you’ve told me, the man your daughter claims is the father truly is.
Lisa says
If the child has a bad cold and eat plus breast feed minutes before swabbing can that affect the result? Or can a child do two dna testing with the first one coming back a match and the second one at o% ?
Identigene says
Hi, Lisa. Eating or being sick doesn’t change DNA. What it can do is affect the quality of the DNA sample, which makes it impossible to extract DNA for testing. If the sample is contaminated in this way, the lab suspends testing and asks for new samples. A report is only issued if samples are viable. And to answer your second question, if a child and a possible father are tested twice, the results should come back exactly the same.
Kelly says
I have two questions:
If someone has had throat cancer and was treated with radiation and chemotherapy, could this impact the DNA collected by a swab?
If the suspected father had a breathing treatment right before the sample was taken, would this impact the DNA collected?
Identigene says
Hi, Kelly. Usually the only processes that could potentially affect a paternity test’s results are a bone-marrow transplant or a recent blood transfusion. What you describe won’t affect results, but it could affect the quality of the sample submitted for testing. Just make sure to swab the cheek for a full 30-45 seconds with each swab and it should be OK. If not enough DNA is collected, the lab will ask for a recollection.
Carol says
I had my sons DNA test done when he was younger. He was on a sterile and adhd medicine. He had poison sumac in and around his mouth. The DNA test results came back a 94% probability but told us he wasn’t the father. I had it redone and looking at both copies they photo copied the results because they dropped one of the swabs and only used one, but refused to open a new one. What do you think?
Identigene says
Hi, Carol. This must have been a long time ago that you did the testing, because with today’s technology, probability of paternity is given as 99% or higher (or 0% if the man isn’t the father). The results you were given (94%) are inconclusive one way or the other. The medicine your son was taking and the poison sumac wouldn’t have changed his DNA, but it could have affected the quality of the sample. If that were the case, the lab would have asked for new samples. It is unclear to me what you mean by “they” photocopied. Who is “they?”
Carol says
He was on a steroid sorry
Jenna says
Can I get an email address I want to send some personal information concerning 2 paternity test…. don’t know how to read the results
Identigene says
Hi, Jenna. Please contact us directly at 800-344-9583.
Becky says
A toothbrush head was stolen from an adult child and father sent both of their toothbrush heads and test came back 0.000% probability that he is not the father. Daughter later revealed that toothbrush was last used by her boyfriend before being submitted so technically two DNA’s. How accurate is the test if DNA on toothbrush was contaminated?
Identigene says
It probably isn’t accurate, Becky. It appears there was only one person’s DNA on the toothbrush or results would not have been issued (if there had been two sets of DNA on the toothbrush, the lab would have caught it and asked questions). The problem is, it’s hard to know if that DNA’s was the boyfriend’s or the alleged father’s.
L. says
I’m getting a home DNA test kit to test a person that I know for a fact that’s the biological father of my son but I fear he’s going to do something to alter the test to get false results back! What should I do to prevent this?
Identigene says
Hi, L. If you want to test at home, you should all swab cheeks in each other’s presence, witness each other putting the swabs in the sample envelopes and all go together to drop off the samples at the post office. If that’s not possible, or if the person lives in a different location, then you should not buy the kit and instead call our parent company, DDC, directly at 800-329-7519. One of our experts will set up legal testing in your area and in the possible father’s location wherein the collections process is witnessed by an impartial, approved party. This costs a little extra than testing at home, but there is zero chance of fraud and results are court-admissible too. Hope this helps!
Betsy says
Hey if the alleged father was kissing another person prior to the test would this affect the results? If so how off could it be? He had been drinking coffee and kissing all over his girlfriend that day and consumed alcohol the night prior. Would these be reasons to ask for another test to be done.
Identigene says
Hi, Betsy. If there had been any problems with the samples or any suspicion of contamination, the lab would have asked for new samples. Since a results-report was issued, the samples were OK.
Brandon says
If my daughter, myself and the man are sick(congested) can we still take the test? Or should we wait until we feel better?
Identigene says
Hi! Really, it’s up to you. If you all feel well enough to do the swabbing properly, then go ahead. But being sick won’t change the DNA itself, so there’s no worries there.
Milla says
My son father licked the envelope after placing the swabs. The results came back that he is the father. He is using cause he licked the envelope that is the only reason my son came back his son. Is this possible or are the results true?
Identigene says
Hi, Milla. No…licking the envelope did not affect the results of his test.
KIM says
How accurate is dna
Identigene says
Hi, Kim. The technology is so sound, that courts accept results as proof of paternity when there is a dispute.
Lewis says
If the swab from the potential father comes in contact with the swab from the child….will that be a positive result or will the lab be able to tell there are 2 samples on the same swab?
Identigene says
Hi, Lewis. The lab can tell and would ask for new samples.
Lei says
Hi
My partner has recently purchased the home DNA kit to test if he’s the biological father of his son.(with his ex)
And I helped to seal the envelope and put his son’s sample in my bag.But I didn’t notice that my bag was wet by the water.
Not sure if his son’s sample got
contaminated by the water and the envelope was a bit broken so I tried to put two of the sample back in the envelope and might have touched the testing part with my fingers for one second.
Will that effect the accuracy of the test?
And can the lab read the female profile from the sample?
Thank you.
Identigene says
Hi, Lei. If the swabs were contaminated in any way, the lab will detected it and just ask for new samples. If results are issued, then it wasn’t a problem. The test does check for gender as well, yes. If you have any other questions, feel free to reach out to us directly at 800-344-9583.
Luis says
i sent in swabs all envelopes containing swabs were wet touching and on top of each other. I licked the envelope and sent it out immediately (samoles did not gave time to dry by themselves) I alsodid not wear gloves when swabbing myself or the child. Would any of these reasons listed above give a false result?
Luis says
(SAMPLES DID NOT HAVE TIME TO DRY BY THEMSELVES) is what I meant to say
Identigene says
Hi, Luis. If the swabs were contaminated in any way, the lab would be able to tell, suspend testing, and ask for new samples. Licking the envelope does not affect the swabs and you don’t have to wear gloves to swab.
Abibi says
I took my son for a dna paternity test, the lady at the lab placeded the tip of my swab together with the alleged father’s swab after swabbing our checks then separated them later. Could that cause a false positive or negative result because I think what she did is as good as just testing the mother and child only by touching the mother’s swab and the alleged father together
Identigene says
Hi, Abibi. If there were two profiles on one DNA swab, the lab would catch it and request new samples. Results would not even be issued and so this would have no effect on your report.
Carolyn says
Hi. My partner really wants our son to be his. So badly that i wonder if he replaced my sons swabs with an extra set of his own to force positive results. Is there any way to tell this?
Identigene says
Hi, Carolyn. Yes, the lab would see that the DNA profile from the child’s sample is identical to the alleged father’s, which is a red flag. A father and child only share 50%
of their DNA. Testing would be suspended and the lab would ask for new samples without issuing results.
Richard says
Hi,
if the alleged uses his sample in the two envelopes( his and the child) will the result come positve.
Identigene says
Hi, Richard. No, because the lab will see that the two DNA profiles are identical and therefore something’s wrong. Testing will be suspended and the lab will ask for new samples.
Krystal says
I have a 6 week old who was crying while we were conducting the test. I was distracted and did not pay attention to only getting the cheek swabbed. I collected a lot of spit. She is breastfed as Well and have a feeding about 10 minutes prior. Is it possible that enough cells were collected during the swab around her mouth although it included saliva?
Identigene says
Hi, Krystal. If the baby’s swabs don’t have enough DNA, then the lab will ask for a recollection. It wouldn’t affect results.
Cari says
Hi, I just have a question about the lab requesting additional samples… is there an additional cost for new samples to be processed, should the lab make the decision that the samples were not usable?
Identigene says
Hi, Cari. No, there’s no charge.
Vanessa says
One the evelopes were ripped, It was the father’s. Will the lab ask for another sample from the father and the baby or just the father. We can’t get another sample from the baby. Also, what is the cost to test two fathers, I dont see that option on the online site. Thanks
Identigene says
Hi, Vanessa. If the possible father’s swabs were contaminated, the lab will ask for new samples. Unless the baby’s were also contaminated somehow, those should be fine. The kit is designed only for performing the single test. Testing an additional possible father requires paying another full lab fee, even if he’s testing with the same child as the original test.To set this up, you’re welcome to call us directly at 800-344-9583.
Amanda says
Hi when gathering the 3 samples, the tops of the 3 qtips from mother, child and alleged father touched for a few seconds. Could this have affected the results? Test came back 99.9% probability that he was the father. Could samples have been contaminated? Will I need to do another test?
Identigene says
Hi, Amanda. If there had been profiles for two different people on any of the swabs, testing would have been suspended and new samples requested. Since you were issued results, there wasn’t a problem and you can trust the answer in your report.
Whitney says
The father only did 2 swabs not three, will it be ok to send?
Identigene says
Hopefully so, Whitney. If not, then the lab will request additional samples.
Diana says
What is the purpose of 3 swabs versus 2 swabs?
HomeDNA Identigene says
Hi, Diana. We provide four (4) swabs total per participant, so there are 12 swabs total in a kit. We provide swabs for three people, because the lab fee includes testing for one child + one alleged father + the mother (her participation is optional, but recommended, in case her data is needed to confirm results).
Brittany says
Hello,
I did not tell the lab, or I do not think I did, that I had a blood transfusion a few years ago. I am uncertain if the father has or not. Will this pose an issue?
Identigene says
Hi, Brittany. It’s been long enough since your blood transfusion that you should be fine.
charity says
if one sample is contaminated do you just request that sample to be retaken or does everyone have to send in a new sample?
Identigene says
Hi, Charity. Only the person who contributed a contaminated sample would be asked to contribute a new one.
Janine says
Our envelopes were wet and one ripped so we put them into separate ziploc bags and sent them. Is that okay? Will we need to retest?
Identigene says
Hi, Janine. If swabs are wet, we recommend holding them in the air to dry for a few minutes…this prevents envelopes tearing from being too wet. Putting wet swabs in plastic bag is conducive to mold growth, which can definitely contaminate the swabs. But if they get to the lab quickly that may not be a problem. If you need to retest, the lab will notify you.
Ariel says
My friend put her sons dna swab in both the envelope meaning her sons in the kids spot and the fathers envelope what would the rest results be
Identigene says
There won’t be any results because the lab will see that the same DNA was put in both envelopes and will ask for new samples.
SallyAnn says
I waited about a week after collecting samples to mail them off . Could this have caused the results to be compromised?
Identigene says
Hi, SallyAnn. If they were kept in normal conditions (not exposed to moisture or extremes of heat or cold), then they would have been just fine. If a sample is contaminated for any reason, the lab always catches it and would have requested new samples before issuing results.
Timothy says
Will smokin/chewin tabbacoo affect the DNA results?
Identigene says
Hi, Timothy. We always recommend that people not eat, drink, smoke, etc. for one hour prior to swabbing. It’s not that doing so would change the DNA, but rather, that it could affect the quality of the DNA sample. If you smoke or chew prior to swabbing and the lab determines the DNA wasn’t affected, then they’ll go ahead and test and issue results. If it’s determined that smoking/chewing contaminated the sample too much to allow testing, then the lab asks for new samples.
Loc says
Hello,
For some reasons, we did swap the tongues instead of cheeks. Is it still okay or do we need to retake the samples? Thanks
Identigene says
It might be OK. If it’s not, then the lab will suspend testing and request new samples.
Chantell says
Hi if the dna come back not the father and there are no other possibilities also he chewed gum right before the swob is it a chance the gum affected the dna ?
Identigene says
Hi, Chantell. No, chewing gum doesn’t change DNA data…it can only affect the quality of the sample, possibly. If results were issued, then it wasn’t a problem. If you tested with an accredited lab, the only way it could show “not the father” if he really IS the biological father is if one or more participants submitted someone else’s DNA. This can only happen with a home test; if it had been a legal test with court-admissible results, IDs would have been checked and DNA collection would be supervised, so there’s no chance of monkey business.
Sasha says
If the paternal personis a drug user such as *street name spice.. or a substance such as that can I effect a test.
HomeDNA Identigene says
Nope.
Kandy says
Can I Test siblings to see if they share the same father? If the father is unavailable to test could you still see if children have the same dad? There are different mothers.
HomeDNA Identigene says
Hi, Kandy. Yes, absolutely. However, it’s best if both mothers can also participate, since it optimizes the chances of getting conclusive results.
Patricia says
How long can samples be left in the envelope before mailing and be good
HomeDNA Identigene says
Hi, Patricia. If the paper envelope is kept in a cool, dry, place then samples remain viable for about six months.
Kasie says
About 10 years ago, before I met my husband, he had a dna test done in court. The lady doing the test put his and the child’s dna swabs together in her hand then placed them in separate envelopes. The results came back that the child was his, even though he swore he never even touched this girl, the child doesn’t look like my husband, I know that doesn’t always mean anything, except out children are identical to my husband and the girls child looked like her ex boyfriend.
Is it possible they gave him a false positive? They admitted mistake could be made, that they were backed up etc. even his lawyer wanted it redone but The girl and her child left state, my husband didn’t think it was worth pursing.
I believe my husband, I didn’t know him when this happened, but I have seen his lawyers reports and have known other people to have gotten false positives, just not in this same way.
HomeDNA Identigene says
Hi, Kasie. It’s extremely unlikely that a false positive could happen this way. A false positive happens when there is another possible father who is a brother/father/grandfather of the man being tested and that information is not provided to the lab. A lab should have detected an additional profile on the swabs if they were contaminated in any way by the lady’s touching the swabs.
Veronica says
If I used the same glove while collecting samples from both the alleged father and baby, could that affect the results? More specifically, if somehow the baby’s saliva got on the alleged father’s swab or vice versa (via the glove), would that show a positive result?
HomeDNA Identigene says
Hi, Veronica. For paternity testing, it is not saliva that is being collected…it is cheek cells. If you scrape the insides of the cheeks only, while avoiding the wet gum areas as much as possible, the swabs should be wet afterwards but not soaking and the glove you’re using should never have to come in contact with the tips of the swabs. If somehow there are two separate DNA profiles on a single swab, for whatever reason, the lab does not issue results. Instead, the lab suspends testing and asks for new samples. Hope this helps!
LDal says
If the lab receives the samples and the envelope is wet will they still attempt to get results or just immediately rule as contaminated
HomeDNA Identigene says
Are you talking about envelopes being wet from saliva? Envelopes don’t arrive wet, unless they’ve been rained on. All samples are evaluated on a case-by-case basis to see if they’re viable for testing. If it’s deemed they’re contaminated, testing is suspended and new samples are requested.
Sarah G says
The alleged father is not located where I am but I sent him the swabs and he sent them back to me but the package was ripped from the wet swabs. But his sample was aready dry when I got it and it did not mix with me and my son’s sample. will the samples still be tested. Also, I swab me and my son in November will that affect anything?
HomeDNA Identigene says
Hi, Sarah. If there are any problems with contaminated samples, the lab suspends testing and requests new samples without issuing results. If a report is issued, then there wasn’t a problem. Your having swabbed yourself and your son in November should be just fine, as long as you kept your swab envelopes in a cool, dry place.
Peter says
I contaminated a few swabs and disposed of them, so is it ok to submit 3 swabs per person instead of 4?
HomeDNA Identigene says
Hi, Peter. If the other swabs contain plenty of DNA, it may work out all right. If there isn’t enough with just three swabs, the lab will suspend testing without issuing results and ask for new samples.
Carla says
can be used for two brothers?
HomeDNA Identigene says
Hi, Carla. Yes, you can use the kit for two children + one alleged father, but keep in mind you’ll need to pay two separate lab fees. Once you get your kit, it’s easiest if you call us to pay and ensure the test gets set up correctly: 800-329-7519 (M-F, 8:30 am to 5:30 pm Eastern).
Corinthians says
My test was mailed Feb 26, 2019 before I set up the online results, once I realized the mistake I made & paid the money for next day results online. Today March 23, 2019 I haven’t got no email or text that lab received my swabs. Should I retake the test and send new samples?
HomeDNA Identigene says
I cannot comment publicly on what’s happening with a particular case, due to HIPAA regulations. Please contact us at 800-329-7519 immediately. We’re available M-F, 8:30 am to 5:30 pm Eastern.
Trina says
I guess I wanted to know could my actions be delaying the results due to me setting up account after I mailed the swabs
HomeDNA Identigene says
Hi, Trina. No, that would not cause a delay.
Alexis says
Will chewing tabbaco before doing a dna test affect the results? The alleged father was dipping while waiting for the test to be conducted than right before the test he took out the tabbaco.
HomeDNA Identigene says
Hi, Alexis. Chewing can’t change DNA, but doing so right before swabbing can affect the quality of the sample, making it impossible to extract from the swabs. If the swab is contaminated, the lab will ask for new samples without issuing results. If results are issued, then chewing wasn’t a problem.
Penelope says
It is good to know that you need to swab your cheek. That is a good thing for me to know because I want to get my DNA tested. I really don’t want to mess it up so I should really pay attention to how they want me to send in my DNA.
Ted says
Father’s (4ea) swab packet done. Son’s (4ea) swab packet done. Set son’s “wet” swab packet on top of father’s dry swab packet resulting in saturation of father’s swab packet from son’s swab packet. Will this compromise results? Based on the previous comments; cheek cells are the driver – not saliva. Can cheek cells be compromised via saliva and or through the paper packets? Indeed…should have read Q&A before. Thank you.
HomeDNA Identigene says
Hi, Ted. The wet envelope may contaminate the other sample or it may not. The lab can detect when two DNA profiles are present on a swab instead of just one, or if a swab is otherwise contaminated and unfit for testing. If either of those happen, the lab suspends testing without issuing results and requests new samples.
Cat says
If my 4 month old had a blood transfusion recently will it be hard to get good DNA results for him and the alleged Father
HomeDNA Identigene says
Hi, Cat. YES. You should definitely wait at least 3 months, just to be on the safe side.
BKent says
My son is mixed(his mom is black and white) I’m black, on the sample envelope should I mark white and black or other and put mixed for him? If I mark black only will it cause for results to come back inaccurate? With him being mixed does that change the pool of testing possibilities?
HomeDNA Identigene says
Put mixed black and white. The racial background only helps the lab to determine the strength of the data.
Jeniffer says
If the tip of the swab was touched could it affect the results?
HomeDNA Identigene says
Hi, Jeniffer. It’s not likely. However, if a swab is deemed to be contaminated and there is not enough DNA on the rest of the swabs to complete testing, the lab will suspend testing and request additional samples. We would then send out additional testing materials to you free of charge. If a results report is issued, then touching the swab wasn’t an issue.
Annoyed says
Has your company considered another method other than a paper envelope. This is very frustrating! Something like a DNA test results eats at your piece of mind when waiting on results. I have had to do a recollection because of cross contamination and now I am in fear I will have to do another. Ours mouths were not excessively wet but we still had to almost leave the sample on a table for 4 hours before being completely dry. It took 7 days to receive my recollection kit in the mail just to do the process all over again. Now I am worried because my two envelopes, which i thought was dry, were on top of each other and I noticed one was wet on top of the other. So if there was cross contamination I must wait another 7 days to get another kit?!?!?! There should be an expedited shipping option for recollection
HomeDNA Identigene says
Hi, and thanks for testing with us. Please don’t assume there was cross-contamination with your samples. It may very well be that there just wasn’t enough DNA on the swabs to perform testing, which is the most common problem. Paper envelopes are the best way to store swabs with DNA on them, since DNA is an organic material and paper “breathes.” We’ve successfully performed millions of tests over the last 25 years and this is the most effective method for transporting DNA for paternity tests. We do offer an expedited shipping option for recollection for an additional fee. If you have any other questions, please feel free to give us a call at 800-344-9583. Here are some swabbing instructions the might be helpful to you for your recollection:
• Don’t eat, drink, or smoke for 1 hour prior to swabbing (this helps ensure there will be a healthy amount of cheek cells and helps prevent contamination)
• Make sure you rub each swab on the insides of the cheeks only…try to avoid the gum areas since they contain a lot of saliva
• Rub each swab for a full 45 seconds each
• If the swabs seem a little too “wet,” just wave them in the air for a bit till they’re dry enough to put in the paper envelopes
DOUGLAS says
If I did the swab but left it out in the air to dry a day or two should I still put it in the fridge in a envelope till I can send it off or is it contaminated
HomeDNA Identigene says
Hi, Douglas. They should be fine. Just send them off as soon as possible. I suggest you FedEx them too, instead of using the postage-paid envelope, so the swabs arrive at the lab as quickly as possible.
Becca says
Hi, is there any possible way the lab will not identify contamination? Why do all the results not come back as 0 if there is no chance the person is the father? The alleged father had a fab just before and I know you have said they will catch it befire testing, what happens if they don’t? Would it come back as negative and is it worth doing another test?
Becca says
Sorry I meant fag (cigarette).
HomeDNA Identigene says
An accredited lab will always identify contamination. Always. Because they can’t complete testing if they can’t extract enough DNA to do the test, you see. And remember, smoking before swabbing doesn’t change the DNA itself…it can only enhance the possibility of contamination.
Stephanie says
When putting the swabs in their envelopes, there is a chance that I accidentally put the baby’s swabs in the mother’s envelope and vice versa. We know the alleged father’s swabs are in the correct envelope. Will the lab be able to see if the swabs are the mother’s DNA and just in the wrong envelope? Or will it cause the result to come back as “not the father?” Thanks!
HomeDNA Identigene says
Hi, Stephanie. If indeed you mixed them up, the lab will figure it out and suspend testing pending getting the mix-up resolved.
Anika says
The patential father swab with the first 2 swabs and used his spit as the last 2 swabs I got results back as 0% did that affect the results as far as not using all the swabs correctly.
HomeDNA Identigene says
Hi, Anika. If there hadn’t been enough DNA to obtain conclusive results, then the lab would have requested new samples. Sounds like that was not needed in the case of your test, and the results are correct for the samples provided.
Carmina says
Hello, the at home paternity test I performed with DDC lab does show the child, alleged father and mother’s name. Are these test results accurate? Does DDC print the names on the results?
HomeDNA Identigene says
Hi, Carmina. Identigene is a retail store-only brand that belongs to DNA Diagnostics Center (DDC). At-home tests we perform only show the names of participants if the test was ordered through one of our corporate partners in good standing. Names are not put on reports that are purchased at retail stores since the identities of participants cannot be verified. And yes, results are absolutely accurate for the samples we are provided.
Kelly says
I took a paternity test with another adult male who is 19 years old to see if I am the father. Right before we swapped he had chewing tabacco in his mouth. Could this alter the test results?
HomeDNA Identigene says
Tobacco use doesn’t alter DNA and cannot change a test result, but it could affect the quality of the swab sample, making testing impossible. Since a result was issued, his chewing tobacco wasn’t a problem.
Ashley Baby says
How long after I take the cheek swabs are they good for if I waited two weeks before sending them will that effect it?
HomeDNA Identigene says
No, it won’t affect it. Especially if the envelopes were kept in a cool, dry place.
Edwina says
I’ve done two DNA test. One with a home kit we all did together and watched and a nother through the court. The first results came out positive he was the father and the second came put 0%. What do i do? They are both top of the line dna testing. I don’t understand why i have 2 different results. How is that possible?
HomeDNA Identigene says
Hi, Edwina. Which one gave a positive result?
