The Multi-Drug One Step Multi-Line Screen Test Device (Oral Fluid) is a lateral flow chromatographic immunoassay for the qualitative detection of Amphetamine, Cocaine, Marijuana, Methamphetamine, Opiate, and Phencyclidine and their metabolites in oral fluid at the cut-off concentrations listed below.

This 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 indicated.
