Frequently Asked Questions
Is a grandparent DNA test as accurate as a paternity test?
A home grandparent DNA test is just as accurate as a paternity test. However, your results might not be as conclusive, especially if you’re only testing with the DNA from one grandparent. If you’d like to strengthen your results, consider having both paternal grandparents and the child’s mother participate in the DNA test.
Can I do a test if only one grandparent participates?
Yes; however, it’s important to note that this will reduce your chances of a conclusive result. We always recommend including both paternal grandparents’ DNA if possible, as well as the mother’s DNA.
Can a grandparent DNA test be done without a mother’s DNA?
A grandparent DNA test can be done without the mother; however, including her DNA can help our team of analysts determine which DNA characteristics of the child come from the father’s side and which come from the mother’s side, which can help strengthen the conclusiveness of the results. HomePaternity always recommends using the mother’s DNA in both single-grandparent and grandparentage (both paternal grandparents) DNA tests.
Can I get a legal grandparent DNA test?
No, HomePaternity does not offer a grandparent DNA test that can be used for legal purposes.
What do the results of my grandparent DNA test mean?
Interpreting the results of a grandparent DNA test can be a little more challenging than a typical paternity test. Calculations for a grandparent DNA test involve statistics, so the results will appear as a probability of relationship (which is shown as a percentage):
- 90% or higher: the relationship is supported by DNA testing
- 9% – 89%: inconclusive result and additional parties need to be tested
- Below 9%: the relationship is not supported by DNA testing
If a probability of relationship (PRI) of 92% is given for a grandparent test, the result could be understood as: “There is a 92% probability that the persons tested share a grandparent/grandchild relationship.”
