Why you should get a paternity test while pregnant

With the widespread availability of at-home paternity testing kits, thousands of parents are finding reliable results for that all-important question: “Who is the father of the baby?” But kits on the retail shelves are designed only for after the baby’s born. What about a paternity test while pregnant?  Some of the reasons you might want to choose a prenatal paternity test include:

  • Wanting to eliminate the nagging stress of not knowing who the father is right now and having to wait months before knowing for sure
  • Making sure the right person is there to help you through your pregnancy, right up to and including being there for the delivery
  • Wanting to start getting legal arrangements going, including child support and custody

Choices for Prenatal Paternity Testing

Traditionally, the only tests available used to be amniocentesis and CVS (Chorionic Villus Sampling), which are invasive tests that may cause miscarriage. Because of this, most doctors do not offer these tests anymore for determining paternity alone. Fortunately, advances in DNA technology have brought about completely safe, non-invasive prenatal paternity tests that provide answers earlier than ever.


How it Works: Getting a Paternity Test While Pregnant

  1.  At a doctor’s office or clinic, the mother’s blood is drawn and the possible father’s DNA is collected via buccal (cheek) swab
  2. Free-floating DNA from the baby is contained in the mother’s blood stream; those cells are isolated from the mother’s and a DNA profile for the unborn child is obtained
  3. The baby’s DNA profile is compared with both the father’s and the mother’s and a probability of paternity is able to be established

Quick Facts about Non-Invasive Prenatal Paternity Testing

  • The mother must be 8 weeks (or more) pregnant
  • A paternity test while pregnant is not an option for a woman carrying multiple fetuses (twins or triplets) because current technology does not permit the isolation of multiple babies’ DNA profiles
  • The cost for a high-quality and reliable non-invasive prenatal paternity test is approximately $1,600, and payment plans are usually available
  • The medical facility that collected samples works directly with the paternity testing lab to get the samples processed and analyzed. Results are generally returned in about one week and they can be used in court, since DNA collection was witnessed


Final Thoughts about Getting a Paternity Test While Pregnant

DNA testing is a booming industry right now and you may find companies online advertising unrealistically inexpensive prenatal paternity tests. Beware of trusting a lab without doing a little research of your own first, because there really are differences in quality and service. Your results are too important to leave to chance. Choose a highly-accredited and respected paternity testing lab with years of experience—you’ll be glad you did.

  1. Okay my fiance has been getting a lot of tests done early in her/ this pregnancy. We are high risk with her being 38. I have my doubts about this time due to issues we have had. I know she has had amniocentesis test run and a bunch of other stuff. She says the baby is healthy and fine. We had a baby 2 yrs ago at 36 and I don’t remember any of this being done. What do I do to find out if my concerns are reasonable?

    • Hi, J. If the doctor has kept amniotic fluid from your fiancee’s test and it hasn’t been too long since the test, then we can definitely do a paternity test from that fluid. If that’s not a possibility, you can do a non-invasive prenatal paternity test as described in this article. If she doesn’t want to do a paternity test while pregnant, you can wait until the baby’s born and do a paternity test using the baby’s and your cheek cells (via a painless swab). All of these options are guaranteed accurate and can give you the answers you’re looking for. I hope this answered your question. If not, feel free to reach out again.

  2. In my case, there is a doubt in the acceptance of the pregnancy a lady seems and claims to have for me. Her frivolous ways has painted the situation black, of which I am not standing to accept any responsibility of the child. But to clear doubting minds and thoughts, suggestions has been raised to go for checks and probably a DNA even before her delivery. She is entering into her 6 months soon. On my submission what advice can be rendered as to certainty and about test to go for.

    • Hi, Bora Kay. I’m sorry you’re going through such stress. If you want to test before the birth of the child, then the Non-Invasive Pre-Natal Paternity test mentioned in this article is the best choice. The results are guaranteed accurate (no follow-up paternity test after the baby’s born is needed). Does this answer your question?

  3. t my name is Danielle an me an my baby father been together before I got pregnant then he started cheating on me so he thought I was stepping out to which I wasn’t so now that I’m pregnant he is questioning that he is the father an I’m 5 months an I want to have a test done asap but I don’t have 100$ or even 500 to do the test I’m not trying to spend that much money i just wish there was a cheaper way that we can take the test without paying all that money for it

    • Hi, Danielle. Paternity tests are not covered by insurance, since they’re voluntary tests that aren’t medically necessary. You may want to wait and do the test after your baby’s born, which doesn’t cost as much. I hope everything goes well for you and your little one!

  5. When having a prenatal DNA test done, does the father have to submit to the testing right away, or will they be able to hold the blood sample from the mother to test with the father on a later date?

    • Hi, Jay. There is a 7-10 day window of opportunity for testing after the mother’s blood is drawn. So her sample is sent to the lab right away and analyzed to profile her DNA and the unborn child’s. The possible father’s sample can arrive at a later date, within a reasonable period of time. You’re welcome to contact us directly for more information at 800-681-7162.

  6. I had a non-invasive DNA paternity test done at 8 weeks gestation. The two potential fathers had cheek swabs and I also had a cheek swab. The test was done in a lab in Canada. How accurate can a lab in Canada be ? The court is requesting another paternity test because it wasn’t done in the U.S. Should I have the blood test done ? My baby is now 8 months old.

    • Hi, Patricia, and thanks for reaching out. Yes, you need to have a legal test done by an AABB-accredited lab. This is a witnessed test arranged by the lab to ensure an intact chain-of-custody every step of the way, from DNA collections to sample-submission to testing. We are a trusted lab for these services and will be happy to help you. Now that your baby is born, no blood sample is required: all samples, including the baby’s, are collected via cheek swab. Please give us a call at 800-681-7162 to get started.

      Your story is a cautionary one for people looking to take a non-invasive prenatal paternity test. The best prenatal tests use a blood sample from the mother in order to best capture the free-floating DNA from the fetus and ensure accurate results. DDC’s prenatal paternity test is the only one that is validated and published. Anyone interested is welcome to learn more here, and call us if they have questions about our process: https://dnacenter.com/dna-paternity-test/non-invasive-prenatal-paternity-test/

  7. I had a non invasive test done with DDC and do have my results. 0.00% chance. How much can I trust these results and should I have a second test done or a test post birth to confirm??

    • Hi, Nik!

      You can do a postnatal test (either an at-home or a legal one) also, but it’s not necessary to confirm results. There are specific metrics we follow to ensure accurate results, and if those metrics are not met, then we do not issue a report. Ours is the only NIPP test on the market that’s been validated and published.

        • It’s never wise to speak in absolutes, but I will say certainly not in the last couple of years. The latest technology is incredibly precise, making today’s analysis extremely accurate and reliable. In fact, when a highly-accredited lab like DDC does a NIPP and it’s a legal (chain-of-custody) test, results are accepted in a court of law.

  8. Dear DDC,
    I am seven months pregnant and I am uncertain as to who is the father of my unborn child. I have one child already, a little boy, and I believe my son’s father is likely the father to my unborn daughter. If I am not able to secure a blood sample or check swab from the potential father who has gone miss the past four months could I use a check swab from my son to get any clarity on the pregnancy? Thank you for your response.

    • Hi, Erica. That’s an excellent question. We can only test with samples from the alleged father and mother for the Non-Invasive Prenatal Paternity Test. After your baby is born, however, we can do a sibling test. Our best wishes for a safe arrival for you and your little one!

  9. I am currently 28 weeks pregnant and unsure of who the father is. I’ve had intercourse with my bf and one other person within the same week. I am looking for a prenatal DNA test. If payment plans are available will my mid wife be able to help me get this completed ? It’s urgent I find out soon , for my self and my boyfriend. Please get back with me asap and let me know

    • Hi, Brooke. Our Non-Invasive Prenatal Paternity test is the only test that’s been validated and published, and yes, payment plans are available. We can make all arrangements for you: this test requires a blood sample from you and a cheek-swab DNA sample from the possible father. Results are back in under a week, and 3-Day Express results are also an option. You’re welcome to call us for a confidential consultation at 800-681-7162. We’re ready to help!

  10. Hi I’m 4 weeks pregnant and I had sex with my daughter father with a condom & I had sex 2 days later with my bf without a condom. I wanted to know if I can swab my daughter cheek and use any other DNA from my bf besides a cheek swab to see who is the father of my unborn baby? Please get back with me

    • Hi, Crystal! You must be at least 8 weeks pregnant to do a noninvasive prenatal paternity test. As for obtaining a DNA sample from the possible father, using a cheek swab guarantees there will be enough DNA to extract in order to conduct the test. Using a DNA sample from any other source is not an option. If you have any other questions, feel free to reach out to us directly at 800-681-7162.

    • Hi, Chris. For a postnatal paternity test, it is possible to extract DNA from other items, such a a toothbrush, but we don’t recommend it. There is an additional non-refundable fee of $150 to determine if the sample submitted will even work for testing, with no guarantee that we’ll be able to use that sample. The only type of sample we accept for prenatal paternity testing is a cheek swab. For more information or to determine how to best test for your particular situation, give us a call at 800-681-7162.

  11. Hello
    Wie ist es beim nicht invasiven vorgeburtliche Vaterschaftstest kann man da zweifelslos aufs Resultat zählen ohne sich unsicher zu fühlen ? ?
    Können bei dem Test Fehler passieren ?

    • Hello
      Sorry der Text war nicht vollständig .
      Beim nicht invasiven Vorgeburtlichen Vaterschaftstest kann zweifelslos aufs Resultat zählen ohne sich unsicher zu fühlen ??
      Können bei dem Test Fehler passieren (fehlresultate ) ?

    • Ja sicher. Wir haben alle Arten von Sicherheitsvorkehrungen getroffen, um eine sorgfältige Handhabung, korrekte Testprozesse und genaue Ergebnisse sicherzustellen.

  12. I have the last question. our result was> 99.9 at the non-invasive prenatal paternity test. we made the DDC with them in the 20th week. Can I fully rely on the result now, do we have to count or still have to test after birth for definitive confirmation? Thanks for the answer

  13. Is> 99.9 the highest score in non-invasive prenatal paternity testing? or are there even higher results? I just want to be sure that I can be reassured. This is a clear confirmation for the paternity, do I see this correctly?

    • Yes, this is absolute confirmation of paternity. It can never be 100%, since this would require testing every man in the world with the same ethnic background.

  14. many thanks for the answers which calm me down, something last I would like to know. What does it look like if you do not know if you expect twins and do the non-invasive prenatal V.Test? do you get a false result with twins or does it simply result in no 0% and no 99.9%?

  15. Thank you . I just wanted to know this for my inner peace. then would the lab notice this at any rate during the testing process when it comes to multiple fetuses? Thank you for your help and a good time.

    • The test itself doesn’t determine if there are multiple fetuses. We rely on potential customers to tell us if they are multiple fetuses. If they do the test very early and don’t know they are carrying twins, we can still issue completely accurate paternity results. What I should have said in my earlier comment is that we cannot determine if multiple fetuses have different fathers.

      • Habe es nicht ganz verstanden sorry . Wenn man die 99.9 % ca in 20. Woche bekommt dann kann es sich nicht um mehrere Föten handeln ? Mir geht es nur um mehrer föten nicht ob von unterschiedlichen väter .

        • Der Test wäre genau, sogar für mehrere Föten. Denn die gesamte freischwebende DNA beider Babys würde immer noch mit der DNA des biologischen Vaters übereinstimmen.

          • Vielen Dank .
            Somit kann der Test in der 20. Woche auch genau aussagen ob die DNA mit dem vater übereinstimmt oder nicht auch bei 2 Föten sofern nur 1 vater in frage kommt und nicht mehrere väter ?
            Habe ich das so richtig verstanden ?

          • Es tut mir leid habe teils probleme mit dem übersetzen .
            Möchte sie nachher nicht noch länger aufhalten .
            Nur Noch kurz auch bei zwillingen kann der Test ein genaues Ergebinis ergeben ? Es kommt nur 1 mann in frage

  16. sorry must ask again. it does not affect me but still wants the confirmation because I live in a fear at the time. Do I understand correctly you would see during the test process when it comes to several fetuses?

  17. I have a question. our result was 0% at the non-invasive prenatal paternity test. we made the DDC with them in the 8th week. Can I fully rely on the result now, do we have to count or still have to test after birth for definitive confirmation? Thanks for the answer
    Some people tell me “0%” is not accurate.(because there were so much variable)
    But 99.9% were comparatively reliable. Is it right?

    • Hi, Jinn. Paternity testing answers a yes/no question: is the man considered the biological father or not. If DNA shows that he most likely is, then a statistical probability of that paternity is given. Anything over 99% is considered conclusive in a court, with most positive tests producing higher than that (but always less than 100%). If DNA shows that he is not the biological father, then there is a 0% probability that he is the father. There is no in between. Ours is the only non-invasive prenatal paternity test that’s been validated and published and we stand behind our results.

  18. Please can a post natal paternal test be conducted when the child is 1 day old? if not, then what should be the age at which the test can be performed. thank you

  19. I did a NIPP when I was 8 weeks pregnant and my results were >99.9 that the man I tested was the alleged father. I have a previous child with this man who is 6. Could previous fetal DNA still be floating in my blood? I just want to make sure this test is accurate. I am due very soon and very nervous

    • Hi, Tina. No, a previous pregnancy will not affect the outcome of a non-invasive prenatal paternity test. Once a child is born, the cell-free fetal DNA disappears from the mother’s bloodstream within hours; therefore previous pregnancies will not interfere with a current prenatal paternity test. All the best to you and hope all goes well with your little one’s delivery soon.
