## Indications for use
The Methadone assay is used for the qualitative analysis of methadone in human urine with a cutoff of 300 ng/mL for use in clinical laboratories. Measurements obtained by this device are used in the diagnosis and treatment of methadone use or overdose. The Methadone assay is calibrated with methadone and is specific for methadone. The Methadone assay provides only a preliminary analytical test result. A more specific alternate chemical method must be used in order to obtain a confirmed analytical result. Gas chromatography/mass spectrometry (GC/MS) is the preferred confirmatory method. Clinical consideration and professional judgment should be applied to any drug of abuse test result, particularly when preliminary positive results are used.
