DNA Paternity Testing

DNA testing and biomedical technology is so advanced nowadays that DNA paternity testing can be done even with the child still in the mother''s womb. This is what DNA test laboratories call the Prenatal DNA Paternity Testing.

DNA Paternity testing is the most accurate way of confirming biological relationships between individuals. The standard way of collecting samples from the individuals to be tested is through the use of oral/buccal swabs. Buccal swabs are relatively easy to use and pain-free since the procedure involves simply rubbing the swab on the inside of the mouth to collect a saliva sample.

The process is relatively simple in that the final DNA profile of the child is composed of a series of bands which can only come from the two parents. If the mother''s bands are deducted from the child profile the remainder must come from the biological father. Any male that may consider himself the father can have a DNA profile produced and compared against the remaining bands in the child''s profile.

Gender identification through DNA testing has also got applications in the field of forensic DNA testing as it provides primary information regarding samples found at the scene of the crime during a criminal investigation. Through the test, it is possible to confirm whether biological remains found at the crime scene belong to males or females. It is also possible to differentiate this even in cases of mixed samples.

There is a difference in a Paternity test that is legally binding and a test that is only for personal use. For instance, if a court orders a paternity test, it must follow a process called the Chain of Custody. This process ensures that each procedure was completely followed to the letter from the collection to the testing and this is more expensive than a regular test also. It is also possible to do a test on a fetus that is unborn. The results are still as accurate, although there is a small risk to the mother or child and it is best to wait until the child is born.

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.

Rather than travelling to a clinic to have samples taken for the DNA test, most people prefer to purchase a home DNA test. As well as being more convenient, buying a DNA test online can be much more cost effective. A home DNA test kit will include everything needed to take the sample ? often a cotton swab which needs to be wiped around the inner cheek to collect cells.

DNA Test labs use the method of buccal swabs that is why DNA sampling and testing is quick and painless. A person ? along with another whom DNA patterns will be compared to - simply rubs a buccal swabs into the inner lining of his or her cheeks. Buccal samples are then collected by the laboratory staff and personnel.
