When doing a genetic DNA paternity testing procedure, the sample comes from the mother, father and child. The mother’s sample may not be mandatory, but without it, the procedure becomes more intense with the analysis of the DNA. Baby’s need to have a mouth swab if a blood sample from the umbilical was not obtained at birth. If you need results before the birth of the child, you can have amniotic fluid tested during the pregnancy.
If two or more of the same family members need testing to determine paternity, all of them are tested along with the mother and the child. This does require more intense testing and will rule out the family members until one person shows results as the father. If testing for a decreased or missing mother or father, you can use the DNA samples from other family member to determine paternity.
Although most of the genetic DNA paternity testing is done for financial reasons, some are done for determining the parentage for a few other reasons. If a father of a child needs to donate bone marrow to the child, a paternity test will conclude if the father is a match and in some rare cases, prove the father not to be the father. In these cases, paternity testing is essential to the health of the child in question.
More reports show that genetic DNA paternity testing takes the lead in genetic testing then any other reason. This results from court ordered support, which a man can request a paternity test to prove he is or is not the father. Genetic DNA testing also may show any underlying problems that may be hereditary. When a mother questions the paternity of the father, she also may not know of any of these problems, which could become serious if not known.
In all, the reasons for paternity testing come down to he said/ she said and courts need answers. Paternity testing in support cases, divorce cases and grandparent rights cases all use genetic DNA paternity testing to settle disputes. Another case of paternity testing that has become known over the years is the fight to keep a surrogate baby, the egg of the mother and father are implanted in a surrogate until birth. In some cases the mother caring the child does not want to give the child the rightful parents, in this case a genetic paternity test will reveal the paternal and maternal parents.
As you can see, there are many reasons for genetic DNA paternity testing. As more testing becomes available, the laboratories doing the testing may become overloaded calling for more labs to accommodate the overflow.
