DNA Test: All about the paternity test

The paternity test is one of the most popular DNA tests currently used to determine, from a biological point of view, the paternity or non-paternity of a subject.

The DNA test can be for informational purposes, to find out if a person is the father of another, or it can also be required for judicial purposes to determine or rule out paternity, either by the plaintiff or the defendant. In these cases, the paternity test is performed using a sample from the alleged father and the son or daughter, which can be taken through buccal epithelial cells. Although it is possible to perform this paternity test without taking any sample from the mother, it is advisable to obtain a more reliable result. That is, the more samples are analyzed, the greater the accuracy of the results obtained in the paternity test.

Sometimes, it is possible that the DNA test must be performed without the presence of the father, as may occur, for example, when the alleged father has died. In these cases, it is possible to take a post-mortem sample from the subject. In other cases, the alleged father may refuse to provide the sample required for the DNA test. In these cases, professionals must resort to reconstructing the subject’s genetic profile through other samples from close relatives, although the results obtained are not as accurate or reliable as those obtained from the alleged father’s genetic sample.
