What Is A Grandparent DNA Test?

A grandparent DNA test is a test that can determine whether or not a person is the biological grandparent of an alleged grandchild.

This type of test is typically used when the paternity of a child is in question and the father is unavailable or unwilling to take a paternity test. 

A grandparent DNA test can also be used to determine the paternity of a child when the mother is unavailable or unwilling to take a paternity test. This testing option may be used for adoption cases.

What can I expect my DNA results to say?

When reading the conclusion of a grandparent DNA test result, there is no clear-cut “yes or “no” answer. Your DNA result’s conclusion will reflect calculations that will show the probability of a relationship between grandparents and a grandchild/children.

Results Accuracy

If there is a probability of a relationship the result will show 90% or higher to support the analysis of your DNA test.

In the event that the analysis does not support the probability of a relationship, the conclusion of the analysis will support it.

A report may also be generated that reflects an inconclusive Grandparent DNA test result. This may sometimes occur if the mother of the child is unavailable for testing. The range for an inconclusive DNA test result is between 9% and 89%.
