Pre-Natal Paternity DNA Testing

Pre-Natal Paternity DNA Testing

Answers Before the Baby is Born

You can prove paternity before the child is born. A large number of our clients choose this option because they simply cannot wait to know. Prenatal paternity testing involves some risk, but it is extremely accurate.

Prenatal DNA Paternity Testing Gives Identity Before Birth

Today’s technology allows DNA testing laboratories to determine the biological father of a child before the child is born. Prenatal DNA Paternity Testing is the most accurate way of determining paternity before a child is born.  A prenatal DNA test is simply a paternity test that is done before birth, while the child is still in the womb.

Accurate results of a prenatal paternity test can be obtained in two ways:

Chorionic Villus Sampling (CVS)

CVS is a medical procedure conducted by an Ob-Gyn. The ideal time for performing the procedure is between 9-13 weeks of pregnancy. CVS is a vaginal procedure that removes a small piece of the mother’s placenta. In order for the prenatal DNA test to take place the laboratory needs the CVS sample along with DNA samples from the mother and the potential father. The mother’s and father’s sample can be collected using a painless cheek swab.


Amniocentesis is a more common medical procedure than the CVS. An amniocentesis can be performed by your Ob-Gyn for a variety of reasons including a paternity test before birth. The ideal time for an amniocentesis is between weeks 14-24 of pregnancy. During the procedure amniotic fluid is removed from the mother’s womb. The DNA laboratory will ask for about 5cc of fluid for testing. The amniotic fluid surrounds the child and contains the child’s DNA. DNA samples from the mother and the father are also needed to perform the prenatal paternity test.

Information About Prenatal DNA Testing

Both the CVS and Amniocentesis involve some risk. Oftentimes, an amniocentesis will be requested by your Ob for other reasons, such as predisposal to disease. This will allow you to request a sample of fluid. Boston Paternity recommends that you consult your physician before deciding to purchase a prenatal paternity test.

When your doctor approves the procedure, Boston Paternity will provide all necessary paperwork to your doctor’s office. Your doctor will perform the procedures, fill out all the necessary paperwork, then send the samples to BP for testing.

  • Medical insurance will not typically cover the cost of a prenatal DNA test. If the amniocentesis or CVS is necessary for a separate health issue, then the cost of the procedure may be covered.
  • The cost of a prenatal test is similar to that of a standard test. You’ll just need to account for any additional doctor fees.
  • We have prenatal paternity experts standing by to answer any questions you have.
