Postnatal DNA testing is one form of parental testing. This technique recognizes the biological father of the child. If there is any doubt about the biological father, this test may be taken. However, remember, that a doctor must prescribe this test. There are certain situations during which the postnatal DNA testing comes in very handy. These tests are done after the birth of the child.
There are various techniques which are used for the postnatal DNA testing. Some of these are mentioned below. Take a look:
- Blood collection and testing: This is an important part of the postnatal DNA testing. In this case the blood is collected from both the child as well as the father and they are tested. Different tests are done before paternity is established. If you are going in for these tests, make it a point to go to a recognized laboratory, which is also accredited by the government. It will get you appropriate results.
- Buccal swab or cheek swab collection and testing: If the child is above six months of age, this Postnatal DNA testing can be done rather than testing the blood samples. Buccal swabs or cord blood collected at birth can be used for this test. This will also help you to get rapid and reliable testing regardless of age. It should also be noted that for purposes of paternity testing, there is no difference between DNA derived from buccal swabs or blood.

| - Umbilical cord collection and testing: Umbilical cord collection and testing is one of the processes of Postnatal DNA testing. The collection of the umbilical chord is clean, painless and does not interfere with childbirth. The doctor clamps and cuts the umbilical cord. Then he or she has to sanitize a small area of the cord and insert the needle into the umbilical vein along with a blood bag attached. The process takes less than 5 minutes. Later on the blood is matched with the blood of the father with the help of different tests.
- Other sample collection and testing (semen, tissue, hair, etc.): Postnatal DNA testing can also be done with the help of semen, tissues, hair and others. The samples are taken both from the child as well as the father and tested in a government-accredited laboratory. This will ensure that you get the most appropriate results.
