The Integrated E-Z Split Key® Cup II is a lateral flow chromatographic immunoassay for the qualitative detection of multiple drugs and drug metabolites in urine at the cut-off concentrations listed below. The test utilizes monoclonal antibodies to selectively detect elevated levels of specific drugs in urine.

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.
