These tests use antibody-based technology to screen for methadone and its metabolites in urine, confirming medication adherence in opioid treatment programs and detecting illicit methadone use in forensic and clinical settings.

DJR devices are Class II medical devices, regulated under 21 CFR 862.3620 and reviewed by the FDA Toxicology panel.
