Prenatal DNA testing is a way to know about the biological father of the child. This test also helps in determining the biological identity of the child. Prenatal DNA testing is done before the birth of the child. This test is similar to the standard paternity test. The child’s DNA profile is matched with the profile of the alleged father. This is calculated based on the DNA markers that are shared between the profiles. The only difference between prenatal and standard paternity testing is the sample collection procedure.
Prenatal DNA testing can be of two types and they are mentioned below. Take a look to know more:
- Amniocentesis: This is one form of prenatal DNA testing. This test is performed during the 14th-20th weeks of pregnancy. The doctor uses ultrasound to guide a thin needle into the uterus through the abdomen. The needle takes out a small amount of amniotic fluid, which is then tested. There are certain risks in this process. There is a chance of harming the baby and also a chance of miscarriage. Other than this, one may also face cramping, leaking of amniotic fluid, and vaginal bleeding. One should consult a doctor before this test
-
Chorionic Villus Sampling (CVS): Another prenatal DNA testing is CVS. In this test a thin needle or tube is inserted from the vagina, through the cervix. This needle is guided by an ultrasound in order to obtain chorionic villi. These are little finger-like pieces of tissue attached to the wall of the uterus. These come from the same fertilized egg and have the same genetic makeup. This test is done between the 10th and 13th weeks of pregnancy. Before this test do not forget to take the permission of doctor.
There are few steps that need to be followed before the Prenatal DNA testing. The steps are given as follows:
First visit a qualified Obstetrician who will perform either an amniocentesis test (after 12 weeks gestation) or CVS (between 9 and 12 weeks gestation) procedure on you. A physician must do amniocentesis and CVS testing in order to obtain a sample for the unborn baby.
In order to collect samples from the alleged father, one must always use a DNA Paternity Collection Kit.

If he is not available to provide you with samples, offer him with different options available after a consultation with the doctor.
After all the samples are collected, then only send the samples for test. This will help the doctors to access the samples in a better way. One can get the report of the tests as soon as the samples are tested. The results will not be disclosed to other people. These are few of the reliable options to determine the biological father of a child.
