Is it Possible to Know Paternity Status During Pregnancy?

Before the birth of the baby, it is absolutely possible to know about the biological father. This can be done with three different testing techniques. Let’s look at each method one by one:


This way of knowing about paternity is done by taking a minuscule amount of amniotic fluid.

What the doctor or attendant does is insert a needle into the mother’s abdomen. This sample then goes to the lab where it’s compared with that of the potential father.

The con of using the amniocentesis technique is that there are greater chances of miscarriage. This test can be conducted within the fifteenth and twentieth weeks of pregnancy.


The main purpose of the non-invasive prenatal paternity test is to assess the fetal DNA in a woman who is pregnant.  After the sample of fetal DNA is taken, it’s then compared to the cheek cell DNA sample of the potential father.

Chorionic Villus Sampling

This method is carried out by taking a sample of tissue from the placenta. In this method:

  • The procedure takes place through the mother’s cervix
  • Or the procedure takes place through the mother’s abdomen

The sample is then compared with the DNA sample from the person who may be the biological father of a baby.

When can the CVS be Conducted?

Usually, chorionic villus sampling or CVS testing is done between ten to thirteen weeks after the mother’s last menstrual cycle. As compared with amniocentesis, CVD has a smaller risk of miscarriage.

Benefits of DNA Paternity Test

The point when a person acknowledged that they are the father by signing a birth certificate – the paternity on a legal level is established. However, singing the birth certificate does not mean that the signing person is the biological father.

A DNA paternity test helps establish the paternity status of a child. This test makes clear who the biological father of the child is. This helps save from a situation in which no alleged person is willing to sign the certificate, and is not willing to give the child the right he or she deserves.
