DRI METHADONE 1, Reagent

The DRI® Methadone Assay is intended for the qualitative and semiquantitative determination of methadone in human urine. The assay provides only a preliminary analytical test result. A more specific alternative chemical method must be used in order to obtain a confirmed analytical result. Gas chromatography/ mass spectrometry (GC/MS) is the preferred confirmatory method.1,2 Clinical consideration and professional judgment should be applied to any drug of abuse test result, particularly when preliminary positive results are used.
