Patients who wish to determine paternity before the baby is born may take a prenatal paternity test. Like a standard paternity test, the prenatal test compares the baby’s DNA profile with that of the alleged father. Because the baby’s DNA is set at conception, the prenatal test gives the same conclusive results as the standard paternity test.

To obtain samples from the unborn child, an OB-GYN uses either of two procedures depending on the stage of pregnancy: chorionic villi sampling (CVS) or amniocentesis. The details of each procedure are tabulated below.

	Chorionic Villi Sampling	Amniocentesis
Stage of pregnancy	10th through 13th week	14th through 24th week
Type of cells collected	Cells from the placenta, a membrane surrounding the developing fetus.	Loose fetal cells released into the amniotic fluid surrounding the developing fetus
Collection procedure	Guided by ultrasound, an OB-GYN uses a catheter through the vagina or a long, hollow needle through the abdomen (depending on the position of the fetus) to collect cells.	Guided by ultrasound, an OB-GYN uses a long needle through the abdomen to collect fluid.

Because both procedures are invasive, there are slight medical risks that the mother must discuss with her OB-GYN.

To arrange for a prenatal test, please call us at 1-888-712-9639 to discuss your situation with one of our caring consultants. We strongly recommend the mother to ask if her OB-GYN is willing to perform the CVS/amniocentesis, or if the OB-GYN can refer her to a local OB-GYN who is willing to do so. We also have a referral list of OB-GYNs who are experienced in the procedure.
