Following positive amphetamine screening at USDTL (United States Drug Testing Laboratories), confirmation testing definitively identifies and quantifies amphetamine, methamphetamine, MDMA, or related compounds. The chain-of-custody protocols and confirmation methodology support medico-legal applications.
This test is used in workplace drug testing, legal proceedings, addiction treatment programs, and clinical situations requiring definitive amphetamine identification. Sample type varies depending on the original specimen.
