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!
