## Indications for use
The On-CallT M Multi-Drug Home Test Cup is a screening test for the rapid detection of drugs in urine at a designated cut-off concentration of 50 ng/mL for Marijuana, 300 ng/mL for Cocaine, 1,000 ng/mL for Amphetamine, 1,000 ng/mL for Methamphetamine, 500 ng/mL for Ecstasy, 2,000 ng/mL for Opiates, and 25 ng/mL for Phencyclidine. The test is intended for over-the-counter (OTC) consumer use. 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.
