Is a Prenatal Paternity Test Safe?
Published January 31, 2026 · Medically reviewed by the partner laboratory's medical director, AABB-accredited relationship-testing laboratory
Yes. Non-invasive prenatal paternity testing (NIPP) requires only a maternal blood draw and a cheek swab from the alleged father — there is zero risk to the pregnancy because no fetal sampling is required. It's safe from 7 weeks gestation and 99.9%+ accurate.
How it works without risking the baby
During pregnancy, small fragments of the baby's DNA (cell-free fetal DNA) circulate in the mother's bloodstream. A standard blood draw from the mother captures both her DNA and the baby's — the lab separates them computationally.

Compared to older invasive tests
Amniocentesis and CVS carry a small miscarriage risk (0.1–0.3%) because they physically sample fetal tissue. NIPP has zero physical risk because nothing is taken from the fetus.
Timing
The test works from 7 weeks gestation — the earliest a prenatal paternity test can be done anywhere. Results in 5–7 business days after both samples arrive.
