Use

This test provides quantitative determination of 6‑acetylmorphine (6‑AM), a metabolite of heroin, in urine using liquid chromatography‑mass spectrometry (mass spectrometry). It serves as a definitive confirmatory assay for heroin use, supporting therapeutic drug monitoring and monitoring for illicit heroin exposure. Quantitative measurement of 6‑acetylmorphine offers specificity for heroin, aiding in confirming suspected heroin ingestion rather than general opiate use. Urine specimens are preferred for monitoring drug and metabolite excretion.
