At-Home Grandparent DNA Test
At-home grandparent DNA test using cheek swabs, for when a parent cannot be tested.
The My Forever DNA® Grandparent At-Home DNA Test Kit helps determine whether an alleged grandparent and grandchild are biologically related - privately from home with trusted lab standards and real human support.
This test is helpful when the alleged father or mother is unavailable, deceased, unwilling, or unable to participate.

A grandparent DNA test compares genetic markers between one or two alleged grandparents and a grandchild to evaluate their biological relationship. A grandchild inherits about 25% of their autosomal DNA from each grandparent on average, with individual variation. The laboratory evaluates the proposed grandparent-grandchild relationship using the participants' genetic evidence, rather than requiring an exact 25% match.
When both biological grandparents from the alleged parent's side can be tested (for example, the paternal grandmother and paternal grandfather), their samples give the laboratory more family reference DNA than one grandparent alone. This may strengthen the statistical evidence, especially in a case that would otherwise remain unclear. Some cases provide strong support with one grandparent, while others need more information.
If only one grandparent is available, the test is still worth doing. If both are available, testing both is worth the $100 fee for the second grandparent's marker analysis.
When testing the possible father's parents, a sample from the child's known biological mother helps the lab account for the maternal DNA and can strengthen the paternal comparison. Her sample is optional and included at no additional cost. For maternal-side testing or a different family setup, your DNA Specialist can advise which additional sample would be useful.
Both grandparent and aunt or uncle testing work through the extended family when a direct paternity test isn't possible. Choose grandparent testing when the alleged father's parents are available and willing. Choose aunt or uncle testing when the grandparents aren't available but a sibling of the alleged father is. The appropriate setup depends on which relatives are available and the relationship being assessed. Your DNA Specialist can help choose the test.
Testing runs through a US-based AABB-accredited and CAP-certified laboratory partner with dual processing. The lab tests 46 DNA genetic markers for grandparent testing. My Forever DNA guarantees a specific 46 DNA genetic markers on every grandparent test.
