Grandparentage DNA Testing

Grandparentage DNA testing helps determine whether an individual is the biological grandparent of a child. This test may be useful when a parent is unavailable for testing or when families need biological relationship verification for personal or legal purposes.

When Testing Is Needed

Grandparentage DNA testing may be used when questions exist about whether a biological relationship exists between a grandchild and one or more grandparents. Common situations include family relationship verification, inheritance or estate matters, adoption-related questions, and circumstances where direct paternity or maternity testing is not available. DNA testing provides a reliable way to help establish biological grandparent-grandchild relationships with a high degree of accuracy.
