What Is a Grandparentage DNA Test?

A grandparentage DNA test compares the genetic profiles of a grandparent (or both grandparents) with a grandchild to determine whether they share a biological relationship. It is most often used when the alleged father is not available for a direct paternity test — for example, when the father is deceased, incarcerated, or refuses to participate. Testing one grandparent yields meaningful results; testing both paternal grandparents dramatically increases the statistical power of the analysis.

How It Works

1
Identify Available Grandparents
Testing one or both grandparents increases the accuracy. We will advise on the best configuration for your situation.
2
Schedule All Participants
Grandparent(s) and the grandchild must both be swabbed. Including the mother of the child can further strengthen results.
3
Buccal Swab Collection
A painless cheek swab is collected from all participants at our Baltimore location or via mobile collection.
4
DNA Comparison Analysis
The laboratory compares genetic markers shared between the grandparent(s) and grandchild, calculating a likelihood ratio.
5
Certified Results Report
The accredited laboratory issues a written report with percentage probability for personal or legal use.

Who Is This Test For?

Frequently Asked Questions

What if only one grandparent is available for testing?
One grandparent is sufficient to run the test, though two grandparents produce much stronger statistical conclusions. Including the child's mother can compensate for having only one grandparent. Call us to discuss the best strategy for your situation.
Should the child's parents be included in the test?
Including the mother is strongly recommended — it dramatically narrows which DNA the child could have inherited from the alleged father's side, making the grandparentage result more conclusive. The alleged father's DNA is, of course, exactly what the grandparentage test is trying to reconstruct.
How accurate is grandparentage testing?
With both grandparents tested plus the mother's sample, accuracy is comparable to a direct paternity test. With one grandparent and no mother, results are still statistically significant but carry a wider probability range. The laboratory reports clearly state the level of certainty.
Can grandparentage results be used in legal or estate proceedings?
Yes, if a legal chain-of-custody collection is requested. AABB-accredited grandparentage results are accepted in Maryland family court, estate proceedings, and inheritance cases. Specify your legal need when booking.
