Grandparent DNA Testing
Grandparent DNA tests also known as Grandparent Relationship Testing allow the parent or parents of the alleged father to participate in a DNA test. A Grandparent DNA test will verify if a biological relationship exists between the alleged grandparents and the target grandchild.
Grandparent testing can include one or both of the grandparents, but including both grandparents offers a stronger result. Also including the biological mother is always suggested in relationship testing. Adding the biological mother helps prevent inconclusive results. If the biological mother is not available, the test can still be performed.
