A prenatal paternity test typically costs between $795 and $2,000, depending on the provider and type of test you choose. The most common option, a non-invasive prenatal paternity (NIPP) test, falls in the $1,500 to $2,000 range at most accredited labs, though some providers offer it closer to $800. That’s significantly more than a standard paternity test done after birth, which runs $100 to $500.
Why Prenatal Tests Cost More
The price jump comes down to the technology involved. A standard postnatal paternity test compares two simple cheek swabs. A prenatal test has to isolate tiny fragments of the baby’s DNA that circulate in the mother’s bloodstream, then separate those fragments from the mother’s own DNA to build a profile. That process requires specialized lab equipment and analysis that a basic DNA comparison does not.
For the mother, the test requires a blood draw. For the potential father, it’s just a cheek swab. No needle, no medical appointment needed on his end. The mother’s blood sample contains enough of the baby’s free-floating DNA to establish a genetic match with over 99% accuracy.
When You Can Test
Most providers require you to be at least 7 to 8 weeks into your pregnancy before ordering a NIPP test. Before that point, there isn’t enough of the baby’s DNA circulating in your blood for the lab to get a reliable reading. Some labs set the cutoff at 9 or 10 weeks to reduce the chance of an inconclusive result. If your test comes back inconclusive because it was done too early, you may need to retest at additional cost, so confirming your gestational age beforehand saves money and frustration.
Non-Invasive vs. Invasive Options
The non-invasive blood draw test is by far the most popular choice and the one most providers recommend. But two older, invasive methods still exist: amniocentesis and chorionic villus sampling (CVS). Both involve collecting a sample directly from the uterus or placenta, which carries a small risk of miscarriage. Because they require a medical procedure performed by a doctor, the total cost can climb higher once you factor in facility fees and the OB-GYN’s time on top of the lab analysis.
For most people, the non-invasive option makes the invasive routes unnecessary. It’s safer, it can be done earlier in the pregnancy, and the accuracy is comparable. Invasive testing is now rarely performed solely for paternity purposes.
Legal Tests vs. Personal Tests
The price you pay also depends on whether you need results that hold up in court. There are two categories:
- Informational (peace of mind) tests give you a private answer. Samples can be collected at home or at a local lab, and results go only to you. These sit at the lower end of the price range.
- Legal (court-admissible) tests follow a strict chain-of-custody protocol. A neutral third party collects and handles every sample, verifies identities with photo ID, and documents the process so the results can be submitted as evidence. This adds $200 to $400 or more to the base price.
If there’s any chance you’ll need the results for a custody case, child support proceeding, or to establish legal paternity, paying for the legal version upfront is worth it. A peace-of-mind result cannot be converted into a legal one after the fact. You’d have to test again.
Insurance and Payment
Health insurance almost never covers a prenatal paternity test. Insurers generally cover genetic testing only when it’s medically necessary, meaning a doctor has recommended it to screen for a health condition. Paternity testing is considered elective, so the full cost comes out of pocket.
Many labs and testing companies offer payment plans to spread the cost over several months. Some charge a flat rate that covers everything from sample collection to results, while others tack on separate fees for shipping, expedited processing, or additional alleged fathers. Ask for a full cost breakdown before you commit, because add-on fees can push a $795 advertised price noticeably higher.
How Long Results Take
Standard turnaround for a non-invasive prenatal paternity test is about 5 to 7 business days after the lab receives your samples. Some companies offer rush processing for an extra fee, cutting the wait to 3 business days or fewer. Results typically arrive through a secure online portal or by mail, depending on the provider. Legal tests may take slightly longer because of the additional documentation and verification steps involved.
What Affects Your Final Price
Several factors push the cost up or down:
- Number of potential fathers tested. Most base prices include one alleged father. Adding a second or third means additional lab work and an extra fee per person, often $100 to $400 each.
- Legal vs. informational purpose. Court-admissible testing adds chain-of-custody costs.
- Expedited results. Rush processing fees range from $100 to $300 at most labs.
- Collection site fees. If you need a professional blood draw at a clinic rather than using a mobile phlebotomy service, expect a separate draw fee of $25 to $75.
Shopping around matters. Prices for the same non-invasive test vary by hundreds of dollars between companies, and the underlying lab technology is similar across accredited providers. Look for AABB accreditation, which is the industry standard for relationship testing labs, and compare total costs rather than advertised starting prices.
