GRANDPARENTAGE DNA TEST.
WHAT IS A GRANDPARENT DNA TEST?
A paternity test is the best way to determine a DNA relationship between an alleged father and a child. However, sometimes the alleged father is unavailable or unwilling to participate in the DNA testing process. In these cases, a grandparent DNA test is an option. The strength of the results will vary based on if one or both paternal grandparents participate in the DNA testing.
