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.

Grand-Paternity DNA Testing FAQ

What is a grandparent paternity test?
A grandparent paternity test is a DNA test with grandparents to determine if their son is the father to the target child.
When should I choose a DNA test with a grandparent?
If a father or alleged father is not willing or not available to test, the grandparent DNA test is the next best thing. The Grandparent DNA test is used frequently for social security survivor benefits.

A father receives all of his DNA from his parents. So any DNA he passed along to his child would have come from either the possible grandmother or the possible grandfather. Therefore, between the two possible grandparents testing with the grandchild’s DNA, they would match in all the same places that a father and child would match.

Can I do a Grandparent Legal DNA Test?
If you are needing a DNA test for death benefits, then it will need to be the legal DNA test.
Can I do a Home DNA Test for Grandparents?
Yes! Home DNA testing kits are available for all of our relationship DNA tests, includind DNA tests with a grandparent.
What kind of DNA sample is used for a Grandparent DNA test?
For all of our home DNA testing kits, a simple buccal swab is the only acceptable sample.

If you choose to do a DNA collection at one of our facilities, the most common sample is a buccal swab. But blood samples can be collected if requested in advance.

Do both Grandparents have to do the DNA test?
There are certain situations that would not require both grandparents testing. To go over the best options for your situation, you may want to call us to discuss.
Is it better to do a DNA test with Grandmother or a DNA test with Grandfather?
If the child at question is a male, it is best to do a DNA test with the Grandfather. When testing 2 males for a relationship DNA test, they have the extra advantage of including Y chromosome testing, if it is necessary. Y chromosomes are an exact match down the male lineage.

If the child at question is a female, a DNA test with the Grandmother or a DNA test with the Grandfather will hold the same level of accuracy.
