Grandparentage DNA Test

When it is not possible to carry out a paternity DNA test, then you may choose to do a Grandparentage DNA test. This test involves testing the alleged father's parents and their grandchild to establish whether they really are the child’s biological grandparents. Siblings might also seek this test to determine the exact nature of their relationship when a sibling DNA test cannot be done.

 You can choose to do a duo grandparentage test, and thus, test both grandmother and grandfather. This test is the one we most recommend as we can map more fully the father’s DNA profile if we have the DNA from both his parents. Genetic inheritance patterns makes it possible to reconstruct the father’s DNA profile by using his parents’ DNA. Once they have created this profile, they may compare it to the grandchild’s DNA profile and calculate the statistical probability of the tested grandparents being the biological grandparents of the child.

If any grandparent is not available for testing, then the grandparentage DNA test can normally be carried out successfully with just one of the grandparents. However, we do recommend that you also send in a sample of the child’s mother’s DNA to help our analysts give you a more accurate result.
When the testing involves solely males – grandfather with grandson - then we recommend selecting the Y-chromosome test.
