Grandparentage testing

Explore a biological relationship through paternal grandparents.

What to expect

This may be an option when the possible father cannot be tested. Cheek swabs are collected from the child, the mother and at least one paternal grandparent. Samples from both grandparents are preferred.

What to bring

Bring government-issued photo ID for adults. Ask us in advance which documents and consent are required for minors. If a court or agency will receive the results, check its requirements before your appointment.

*Estimated turnaround starts when the lab receives samples from all participants.
