The Carolina Liquid Chemistries Cocaine and Cocaine Metabolite Enzyme Immunoassay (COCM) Test System is intended for the qualitative determination of benzoylecgonine (cocaine metabolite) in human urine at a cutoff value of 300 ng/mL. The assay is designed for professional use with a Carolina Liquid Chemistries CLC6410 automated clinical chemistry analyzer. For in vitro diagnostic use only. The assay provides a rapid screening procedure for determining the presence of benzoylecgonine in urine. The assay provides only a preliminary analytical result. A more specific alternative chemical method must be used to obtain a confirmed analytical result. Gas or Liquid Chromatography/Mass Spectrometry (GC/MS or LC/MS) is the preferred confirmatory method. Clinical considerations and professional judgment should be exercised with any drug of abuse test result, particularly when the preliminary test result is positive.

Indications for use as stated in the FDA summary.
