grandparentage dna test

Why test with the grandparents?

 

A direct paternity test is always the best option to determine a biological relationship between a child and alleged father. In instances where the alleged father is unavailable or unwilling to participate in DNA testing, a grandparentage test is another option to consider.


  • Includes one or both alleged paternal grandparents and a child
  • Indicates the likelihood that the alleged grandparent is more or less likely to be related to the child based on the genetic material exhibited by each person
  • Can be used for legal or peace of mind purposes


 A grandparent DNA test determines whether a couple could be the biological grandparents of a child.  It is an indirect way to determine family relationships when an alleged father is not available for a paternity test.  The mother's participation is encouraged to expedite analysis; motherless grandparent tests take longer to complete because of the extended analysis required.
