A grandparentage test from DDC can definitely determine whether a child is biologically related to his or her grandparents. This type of DNA test is typically conducted when a child's alleged father is unavailable for paternity testing and the child's paternal grandparents would like confirmation that the child is related to them. Or in immigration cases if the mother is deceased and the maternal grandparents are making an application on behalf of the child.
All children inherit their DNA from their biological parents. Therefore, we can compare the DNA profiles of a child and his or her alleged paternal or maternal grandparents to determine if the child inherited DNA from them—presumably through the mother or the alleged father.
Grandparentage DNA testing requires the participation of a child and both alleged paternal grandparents (i.e., the grandparents on the alleged father's side). Whenever possible, we encourage the child's mother to contribute a DNA sample as well. Her participation expedites the testing process; a motherless grandparentage test takes longer and requires more analysis than a test that involves the mother.
Although far less common, a grandparent DNA test can also be performed with a child and his or her alleged maternal grandparents. In this scenario, we would encourage the child's father to participate, if possible.
A grandparentage test costs £411. When needed, we can test more than one child against the alleged grandparents; please review our fee schedule for details.
