What are the types of advanced Paternity DNA test?

  • Related Fathers Paternity Test– This test is carried out when the alleged fathers of a child/individual are themselves biologically related. Related fathers can invalidate test results of standard tests, unless all parties are tested. This DNA test is guaranteed to provide conclusive results.

How does the Related Father Paternity DNA test work?

By increasing the amount of DNA markers analysed in the Paternity test, the DNA evidence is increased again so that the above does not prevent a conclusive and highly accurate result being achieved.

The Related Father paternity test analyses a DNA strand to create a DNA profile for each test participant. The DNA profiles of the test participants are then compared.

The number of markers is then increased as required until the greatest level of conclusiveness is achieved.

How are the results interpreted for the Related Father Paternity Test?

The DNA profiles generated for each test participant are compared and the percentage probability will indicate whether the tested relationship exists or which relationship is most likely to exist.

In related father paternity tests, the results can provide more information than standard tests.

For example, in the case that the alleged fathers are two brothers, the test will analyse the probability of whether the participants are; father and daughter, uncle and niece, or whether they are more likely to unrelated. This advanced paternity test provides evidence of whether the male tested is the biological father of the child, whether he is the uncle of the child – therefore suggesting his brother is the father, or whether it is more likely he is unrelated to the child – suggesting that neither he nor his brother is the biological father of the child tested.
