Prenatal Paternity Test in India

Patients who wish to determine paternity during pregnancy 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.
The buccal swab samples from the mother and alleged father are usually collected at the time of prenatal sample collection.

Viability Test
A DNA viability test is performed on unusual samples to check for the presence of usable DNA for a paternity or other DNA tests. In paternity cases where the alleged father is missing or unavailable, we may be able to use preserved samples such as blood, hair, or other body tissues.
The viability test fee is variable and depends on sample type and condition. This non-refundable fee is separate from the paternity test fee and needs to be paid before testing begins.
If the viability test reveals the presence of usable DNA, our consultants will call you to arrange sample collection for the other test participants. A standard DNA test will then proceed.
