Grandparentage Testing

We recommend that both alleged grandparents, if possible, take part in the testing to ensure a more accurate result. If not, it can be performed with one grandparent.

Our prices for these tests are as follows: 

  • Non-legal testing of the mother, one child and one grandparent: $400
  • Non-legal testing of the mother, one child and two grandparents: $425
  • Non-legal testing of one child and one grandparent: $400
  • Non-legal testing of one child and two grandparents: $400
  • Legal testing of one mother, 1 child and one grandparent: $450
  • Legal testing of one mother, 1 child and two grandparents: $450

A paternity test is preferable when the alleged father is available, but testing the grandparents can be your next viable option. Testing the mother also greatly helps in providing answers. If you’d like to know about grandparentage testing, contact our office for more. We often sample DNA for grandparentage and will provide you with the most accurate results possible.

The DNA testing process

Why is it helpful to also test the mother? This way, we can tell which part of the child’s DNA comes from the maternal side (since everyone’s DNA comes half from the mother and half from the father).

If only one grandparent and one child is available for testing, it’s not possible to come up with a complete assessment of the alleged father’s DNA. In these cases, we will compare the child’s genetics to the possible grandfather. We will examine things like the number of shared genes and certain patterns in the makeup. A statistical analysis will then give us the “grandparentage index.” If it’s less than 1.00, the chances that the two people are related are not likely. A result greater than 1.00 means that it’s likely they are related.

We can also perform the same type of tests on the alleged maternal grandparents in situations in which the mother and child were separated early in life and there is no possibility of a maternity test.
