One of the more commonly known forms of prenatal paternity testing involves collection of DNA through a process called amniocentesis. This collection method takes place between the 14th to 24th week of pregnancy. If you choose this collection method your doctor will need to take a sample of your amniotic fluid. Amniotic fluid is the fluid that is found in the sac that surrounds your unborn baby. This fluid can be collected using a needle that is inserted through your abdominal wall. This procedure also carries a small level of risk with it. However, experts believe that it is safer than chronic villi sampling.Fetal Cell/DNA
Having a prenatal paternity test using fetal cell/DNA uses the safest method of collection for your unborn baby. This method of testing uses only the mother’s blood and a sample from the possible father, or fathers to obtain DNA results. Unlike CVS or amniocentesis this method of DNA collection has absolutely no risk of causing injuries to your unborn child, inducing labor or causing a miscarriage. This test uses the fetal cells and DNA that are abundant in the mother’s bloodstream, as a sample for prenatal paternity testing. The only requirement for this test is that you be at least 13 weeks pregnant and it is just as accurate in result as both CVS and amniocentesis.
