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 is required and uses either of two procedures depending on the stage of pregnancy: chorionic villi sampling (CVS) or amniocentesis. The details of each procedure are described 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.
*NOTE: MOST Physicians are not willing to perform the procedures due to the associated risks and suggest waiting until after delivery where there is no associated risks for the mother or child.
However, if your physician determines that the procedure is acceptable please call us with the MD’s contact information and we will coordinate the sample collection for you.
To arrange for a prenatal test, after speaking with your local OB/GYN, please call us immediately to discuss your situation with one of our caring consultants. We can not provide an MD referral list.
