Paternity testing during pregnancy involves extracting the genetic material of the fetus in the mother’s body for testing with the genetic material of the male to be identified. One of the methods used to extract fetal genetic material for paternity testing during pregnancy is the extraction of venous blood from the pregnant woman, and the other is the extraction of amniotic fluid. The extraction of the pregnant woman’s venous blood is a non-invasive test method. The DNA fragment of the child from the pregnant woman’s venous blood is extracted and tested against a sample of the suspected father, and the parentage can be determined. If you are not comfortable with this method of testing, then the genetic material of the child can be extracted by intrauterine puncture of the amniotic fluid and tested against the sample of the male to be tested, which is more accurate.
