Methadone Metabolite (EDDP) Cal- 1000 mg/dL (10 mL)

The DRI® Methadone Metabolite Assay is intended for the qualitative and semiquantitative determination of the presence of Methadone Metabolite, (2-ethylidene-1, 5-dimethyl-3, 3-diphenylpyrrolidine or EDDP), in human urine at cutoff 1000 ng/mL. The semiquantitative range of the assay is 31-2000 ng/mL. The assay provides a simple and rapid analytical screening procedure to detect methadone metabolite in human urine. This 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.
