Siblingship testing

Assess whether two people are likely to be full or half siblings.

What to expect

Cheek swabs are collected from both people being tested. Samples from the mother or mothers can help interpret results and are encouraged when available.

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.
