DNA paternity testing is analyzing the genetic profiles of an individual mainly to determine the biological father, wherever there is a dispute in this regard. This is done by collecting the blood samples of the concerned persons i.e. the child, suspected father(s) and also the mother if required. It could also be done by collecting the saliva from the inner portion of the cheek with the help of a buccal swab of the persons concerned. DNA paternity testing is also done to know the genetic make up of a person and also the family medical history to understand the possibility for a person to get infected with a particular disease. It is becoming popular now and is done by more and more people to know the chances for them to suffer from a certain genetic disease.
