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
Who Is This Test For?
- Grandparents seeking to establish a biological connection for custody or visitation rights
- Families where the father is deceased or unavailable
- Estate and inheritance proceedings requiring proof of biological lineage
- Families reconnecting across generations
- Child support or benefits cases where paternity must be established indirectly
What to Bring / How to Prepare
- ✓Valid government-issued photo ID for all participants (grandparent(s) and grandchild)
- ✓Testing both paternal grandparents dramatically increases statistical confidence — include both if possible
- ✓Including the child's mother further strengthens the result — highly recommended
- ✓Minor grandchild must be accompanied by their legal guardian
- ✓Payment method — call for exact pricing based on number of participants
