Yes — you can absolutely get a paternity test while pregnant. Modern prenatal DNA testing technology allows expectant mothers to establish paternity as early as 7 weeks into pregnancy without any risk to the baby. This guide explains how prenatal paternity testing works, what it costs in Dallas, and what you need to know before booking your appointment.
What Is Non-Invasive Prenatal Paternity Testing?
Non-Invasive Prenatal Paternity testing, also called NIPP testing or non-invasive prenatal DNA testing, is a method of establishing paternity during pregnancy using only a sample of the mother's blood. The test works by isolating cell-free fetal DNA that circulates in the mother's bloodstream during pregnancy.
Because the test only requires a blood draw from the mother and a cheek swab from the alleged father, it is completely safe for both mother and baby. There is no needle or sample taken from the fetus.
How Early Can You Get a Prenatal Paternity Test?
NIPP testing can be performed as early as 7 weeks of pregnancy, measured from the first day of your last menstrual period. Earlier is not possible because the concentration of cell-free fetal DNA in the mother's blood is not sufficient before this point to provide an accurate result.
If you are unsure of your gestational age, your OB-GYN or midwife can confirm this for you before your appointment.

Is Prenatal Paternity Testing Safe?
Yes. NIPP testing is completely safe for both the mother and the baby. The test requires only a standard blood draw from the mother's arm — the same type of blood draw you would have for any routine prenatal bloodwork. No sample is taken from the fetus, uterus, or amniotic fluid.
This is in contrast to older invasive methods such as amniocentesis or chorionic villus sampling (CVS), which carry a small risk of miscarriage. NIPP testing carries none of those risks.
Is Prenatal DNA Testing Accurate?
NIPP testing processed through our AABB-accredited laboratory partner achieves 99.9% or greater accuracy in determining paternity. This is the same level of accuracy as post-birth DNA testing. Results are reported as either paternity established (99.9% or greater probability) or paternity not established.
Can Prenatal Paternity Results Be Used in Court?
Yes — if the test is collected with chain-of-custody procedures at a certified collection site. At Gray Positive Solutions, we offer legal NIPP testing that follows strict chain-of-custody documentation, making the results admissible in Texas courts for child support, custody, and other legal proceedings.
If you only need the results for personal knowledge, we also offer non-legal NIPP testing at the same price point.
What to Bring to Your Prenatal DNA Test Appointment
- Valid government-issued photo ID for both the mother and alleged father
- Documentation confirming gestational age if available (ultrasound report)
- Court paperwork if this is a legal test ordered by a court or attorney
- Payment — NIPP testing starts at $1,499 at our Dallas location
Can You Do a Prenatal DNA Test Without the Father?
The alleged father's DNA is required for the test to produce a result. Without his sample, there is no paternal DNA to compare against the fetal DNA. If the alleged father is deceased, incarcerated, or refuses to participate, contact us — there may be alternative options depending on your situation.
