Paternity Testing During Pregnancy: Your Options
Published February 11, 2026 · Medically reviewed by the partner laboratory's medical director, AABB-accredited relationship-testing laboratory
During pregnancy, non-invasive prenatal paternity testing (NIPP) is the only safe option — a maternal blood draw and paternal cheek swab from 7 weeks gestation, with zero risk to the pregnancy. Older invasive options (amniocentesis at 15+ weeks, CVS at 10–13 weeks) carry a small miscarriage risk and are no longer recommended for paternity alone.
NIPP is the modern standard
Blood draw from mother, cheek swab from alleged father. Cell-free fetal DNA circulating in the mother's blood is separated computationally. Safe from 7 weeks. 99.9%+ accurate.

Amniocentesis and CVS
Both physically sample fetal tissue and carry a small (0.1–0.3%) miscarriage risk. Almost never used for paternity alone now that NIPP is available — occasionally done when the mother is having invasive testing for other reasons.
Post-birth option
If you're not in a rush, waiting until birth and using a standard $99 cheek-swab test is the cheapest, simplest option — same 99.99%+ accuracy, no maternal blood draw needed.
