About Grandparent DNA Testing
Welcome to, the first company dedicated to grandparents seeking information about DNA testing to prove biological family relationships. On this site, you'll learn about the different DNA tests available and the various situations in which grandparent DNA testing (also known as grandparentage testing) and other types of DNA tests can be useful. Learn more About Us.
Why Grandparentage Testing?
Grandparents seek DNA testing on their grandchildren for either of 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 (Read more about these situations.) With a DNA grandparentage test, you can conclusively determine if a child is your biological grandchild or not.

Grandparentage testing is usually performed when the possible father is not available for a DNA paternity test. In such cases, we can test the biological parents of the possible father and compare their DNA with the child's DNA to see if the possible grandparents have passed down their genetic material to the child through the father. Conversely, we can also test for maternal grandparentage to confirm biological relationships in situations where a mother and child were separated early in life, but the mother is no longer available for a maternity test.

Can I do this at home?
Grandparentage testing can be done privately, with those being tested collecting samples themselves, in the privacy of their own home. The results of this test are for personal knowledge only and cannot be used as evidence in a legal proceeding, such as child custody. A chain-of-custody grandparentage test, which can be used in court, requires tested parties to have their samples collected by a trained professional, usually at a clinic or laboratory.

Wanting to be sure...

"My grandson looks nothing like my son, and I know his mother has not always been faithful. My son is very loyal and is reluctant to take a paternity test. How else can I find out if the boy is really my grandson?" more...


"My son passed away almost five years ago. Now, some woman who he dated over 10 years ago contacted me to say her daughter is my son’s. How do I know this isn’t a case of mistaken identity? " more...

A Difficult Situation...

" My son is only 16, and now he has a son of his own. At least, that is what the mother says. He is not even seeing the mother anymore and has no custodial rights, but I read that I might be liable for his child support payments. How do I know the child is actually my grandchild?" more...
