Paternity test (DNA testing) is the exact method of determining the degree of relationship between a child and his father. Besides medical applications, maternity tests can be an extremely delicate issue for those involved, often betraying partner's distrust. There are several options for paternity tests, depending on the moment you want to do it: before or after childbirth.
Prenatal DNA testing (before childbirth)
This prenatal paternity test can be done in the second trimester of pregnancy between the 14th week and 20th week of pregnancy. The procedure can be risky. You might have abdominal cramping, leaking of amniotic fluid, vaginal bleeding, which can harm the fetus or even cause an abortion. How is it amniocentesis performed?
The doctor introduces a thin needle into the uterus through the abdomen. The needle collects a small amount of amniotic fluid, which is studied and tested. It is recommended that you consult your doctor to obtain approval for this type of testing. Chorionic villus sampling (CVS)
This test is done by introducing a needle or tube into the vagina, through the cervix, using ultrasound to obtain chorionic villi (small pieces of placenta tissue attached to the uterus). This procedure can be done in the early stages of pregnancy (from weeks 10-13). It is also required the doctor's permission to perform this type of analysis and to get information about potential risks.
Postpartum DNA testing (after childbirth)
This procedure consists in blood sampling and examination of blood groups of parents and children. Mother's blood is not required. After the blood analysis, the results of the genetic profile of the baby will be compared with those of the presumed or alleged fathers of the child. If the genetic profiles of children and one of the potential fathers are similar, the paternity is 100% confirmed. The DNA test can be done by analysing cells sampled from the inner cheek or other types of biological samples (semen, tissue, hair). The same test can be made by testing the child's umbilical cord. Home paternity tests
If you want to make a home paternity test, you will receive a kit and information about the steps you must follow. To collect DNA samples, from the oral cavity, you will probably use a brush. This procedure requires specific attention because it can easily damage genetic material. Final word
Paternity tests can have serious emotional implications, especially if the result is not the one expected. This must be considered before the test. Think also about the consequences of the results.
