Grandparentage DNA Test
Grandparetnage DNA testing determines if an individual (or a couple) and a child are biologically related as grandparent(s) and grandchild. It is often used to determine paternity indirectly in cases where the alleged father is deceased or unavailable for testing. Since we all inherit half of our DNA from our biological father and half from our biological mother, we inherit a quarter of our DNA from each of our biological grandparents.
The grandparentage DNA test can be conducted with or without the child’s biological mother’s participation. Mother’s participation is encouraged because that will help exclude half of the child’s DNA when comparing the child’s DNA to the grandparents’.
When you are ready to proceed with a grandparentage DNA test, you can call 1-800-914-1002 to discuss the testing process and fees with one of our DNA case counselors. Once your case is set up, we will arrange convenient specimen collection appointments for all tested parties. Once all specimens arrive, it will take 5 to 9 working days for our laboratory to complete the testing.
Our grandparentage DNA test generates conclusive results to answer the question of whether or not the tested parties have a grandparent-grandchild relationship. It also indirectly confirms paternity between the child and the alleged father if he is not available for testing.
The chain-of-custody grandparentage DNA test results can be used for legal issues such as inheritance and immigration petitions.
