Walk-In Paternity Testing: What to Expect
Published January 27, 2026 · Medically reviewed by the partner laboratory's medical director, AABB-accredited relationship-testing laboratory
Legal (court-admissible) paternity testing requires an appointment, not a walk-in — the chain-of-custody rules that make the result admissible require confirmed identity verification and scheduled collection. Same-week appointments are available at partner facilities near every U.S. metro after you order online.
Why appointments, not walk-ins
Chain-of-custody requires the collector to expect specific named participants, verify their government IDs, and log the collection into a signed log. Walk-ins would break the chain.

What to bring
Government-issued photo ID for each adult, birth certificate or Social Security card for each minor, and the child. The technician handles everything else.
