The ACON multi-CLIN™ Drug Screen Test Device is a rapid chromatographic immunoassay for the qualitative and simultaneous detection of Amphetamine, Barbiturates, Benzodiazepines, Cocaine, Marijuana, Methylenedioxymethamphetamine, Opiates, Oxycodone, Phencyclidine, Propoxyphene and Tricyclic Antidepressants in urine. The designated cut-off concentrations for these drugs are as follows: Amphetamine 1,000 ng/mL, Barbiturates 300 ng/mL, Benzodiazepines 300 ng/mL, Cocaine 300 ng/mL, Marijuana 50 ng/mL, Methylenedioxymethamphetamine 500 ng/mL, Opiates 300 ng/mL, Oxycodone 100 ng/mL, Phencyclidine 25 ng/mL, Propoxyphene 300 ng/mL and Tricyclic Antidepressants 1,000 ng/mL. They are intended for healthcare professionals including professionals at point-of-care sites.
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 used.
Indications for use as stated in the FDA summary.
