One of the medical tests for which there is growing demand all over the world is the DNA testing. DNA testing is also known as the DNA typing and genetic fingerprinting. It is generally defined as the technique which is employed for assisting the identity of the individuals through the DNA profile. It is used for criminal investigation and parental testing purposes. The medical theory is that the persons who are closely related to each other have the similar set of the DNA sets.
The court of law also admits the result of the paternity testing as the irrefutable medical test. There are many types of Paternity DNA testing which you can do to ascertain the paternity of a child. The DNA test can be done before and after the birth of the child.
Postnatal DNA test
If you would like to do the DNA test after the birth of the child, there are some methods with which you can do the child’s DNA testing. You can collect the blood of the child and the father and test these blood samples and match them. You can also take the Buccal that is cheek swab of the both child and the father and test for matching DNA samples. You can also collect the umbilical cord of the child after the birth and do the DNA test and match with father.
Prenatal DNA Test
If you do not want to wait and would like to do the DNA testing before the birth of the child, you can do some paternity testing. You can do the paternity testing which is known as the amniocentesis. This procedure includes the penetration of a thin needle in the uterus, through the abdomen. Through this thin needle, a small amount of amniotic fluid is drawn out and can be tested for the DNA testing. But this test is very dangerous. Due to this, there is the chance of the miscarriage and other side-effects which include leaking of amniotic fluid, vaginal bleeding and cramping.
The other paternity testing which can be done before the birth of the child is Chorionic Villus Sampling. This test can be done in the early pregnancy from 10th to 13th weeks. A thin tube or the needle is inserted through the vagina, which goes through the cervix and chorionic villus is obtained. As the test is a little dangerous, a doctor’s consent is necessary for conducting this procedure for DNA testing.
DNA profile technique was introduced in 1984 by Sir Alec Jefferys who was at University of Leicester, UK. Since, then DNA testing has become an important medical test which has many uses from the paternity testing to the DNA testing which are employed to identify the identify the suspect of many kinds of the crimes. In many countries, the laws of the country have included clauses which include the result of the DNA testing as the medical evidence. The accuracy of the DNA testing has been proven over and over all over the world.
