Can You Get DNA Tests Done While You Are Pregnant?

Uncertainty about the father of an unborn child can be stressful and upsetting to a pregnant woman. Two tests, available during pregnancy, can determine the father of the unborn baby.

DNA Testing

• DNA testing compares samples of DNA from a child and from an adult to determine paternity. Tests can be performed during pregnancy or after the birth of the child.

Chorionic Villus Sampling (CVS)

• During a CVS, a doctor uses an ultrasound to guide a thin needle or tube through the abdomen or into the vagina and through the cervix to collect a sample of chorionic villi. According to the American Pregnancy Association, chorionic villi are attached to the wall of the uterus and contain identical DNA to the fetus. CVS is generally performed between weeks 10 and 13 of pregnancy.

Amniocentesis

• Performed in the second trimester, typically between weeks 14 and 20, an amniocentesis tests a sample of the amniotic fluid, collected by inserting a thin needle through a woman's abdomen and uterus. An ultrasound is used during the test to guide the needle.

Risks and Side Effects

• According to AmericanPregnancy.org, CVS and amniocentesis both carry an increased risk of miscarriage due to their invasive nature. Other side effects include spotting, cramping and infection from a CVS, and leakage of fluid and irritation at the puncture site from an amniocentesis.

Warning

• Talk to your doctor to ensure proper DNA testing and/or recommendations based on your individual case. A doctor's consent is required for a CVS or amniocentesis when used for DNA testing.
