The question of whether a man is a child's father can become a hotly contested issue rather quickly. In courts all over Florida and the United States, paternity tests have become a common practice. These tests use DNA to determine if two people are father and son. There are two different kinds of paternity tests, prenatal and postnatal.
A postnatal paternity test is, of course, performed after the baby has been born. Either a buccal swab or blood sample can be taken from the potential father to compare with that from the baby. The sample from the child can come from the blood or buccal specimen, or the umbilical cord.
Prenatal paternity tests are a bit different. These can done while the mother is still pregnant, and can be invasive or noninvasive. For the noninvasive test, a blood sample is taken from the mother, and a blood or buccal sample is taken from the potential father. Since the baby's DNA can be seen in the mother's blood as early as seven weeks, this method is valid. For the invasive test, a needle is injected into the abdomen.
Of course, any procedure that requires an insertion of a needle into the uterus will carry some risks. Because of this, many choose the noninvasive methods. Anyone who needs a test to determine paternity in Florida can consult with a family law attorney. He or she can help the client decide which type of testing is best for his or her situation, as well as the steps necessary to resolve paternity issues properly.
