Paternity Testing During Pregnancy
If a woman is pregnant and urgently needs a paternity test, prenatal paternity testing may be an option for her.
A prenatal paternity test can be performed only if the mother is between 10 and 24 weeks pregnant. This is because the procedures used to collect the baby’s sample can only be performed during this time period.
- If the mother is 10-13 weeks pregnant, her baby’s sample can be collected using chorionic villi sampling (CVS).
- If the mother is 14-24 weeks pregnant, her baby’s sample can be collected using amniocentesis.
Both of these sample collection procedures require the participation of an OB-GYN. Also, because the procedures are invasive, it is recommended that the OB-GYN discuss the risks involved with prenatal testing with the mother. If the mother doesn’t have an OB-GYN or would prefer to use someone other than her regular OB-GYN for the paternity test, our prenatal specialists may be able to refer her to a doctor.
While the baby’s samples are collected by an OB-GYN, the mother and alleged father collect their own samples using the buccal swabs supplied in the free Beta Self-Collection™ Kit. We will ship the kit to the test participants within 24 hours of receiving their order.

Thank you for this information. I will ask my doctor so I can plan for this testing. But if the risk includes harming my baby, I will not have this test done. I will inquire on this with my doctor. Thank you.
