Non-legal tests are for personal knowledge, not court use. Legal tests use verified identity and documented chain of custody to support court use when applicable requirements are met.
Court-ready documentation
Chain of custody collections performed with photo ID verification, participant photos, and tamper-evident sealing.
Accredited lab partner
Certain legal DNA testing services are coordinated through an AABB-accredited laboratory partner that performs all analysis.
DFW direct, nationwide coordinated
We collect directly across DFW — homes, offices, hospitals, and attorney offices. Outside DFW, testing is coordinated through Universal Forensics and partner affiliate collection facilities.

We confirm the expected timeframe for your results with you before the appointment and keep you updated.
