Grandparentage DNA Testing - The Purpose

The best testing scenario is a grandparentage DNA test that includes the mother, child and both of the alleged father's parents. By including both of the alleged father's parents, the alleged father's DNA profile can be reconstructed. Comparing the alleged father's reconstructed profile against the child's DNA can allow this testing scenario to give results as accurate as a paternity test.

A test can be done if only one paternal grandparent is available, although it is recommended that both paternal grandparents test. With only one paternal grandparent, the missing father's DNA cannot be reconstructed. In this situation, the paternal grandparent and child will be tested and their genetic information will be compared.

Grandparents seek DNA testing on their grandchildren for two common reasons: they have doubts about the paternity of their son's or daughter's child, or they would like to prove that they are related to a grandchild whose family denies the relationship and bars them from developing a relationship with the child. With a grandparentage DNA Test, you can conclusively determine if a child is your biological grandchild or not.
