## Indications for use
The Alinity c Cocaine assay is a homogeneous enzyme immunoassay intended for the qualitative and/or semi-quantitative determination of benzoylecgonine (Cocaine Metabolite) in human urine at a cutoff concentration of either 150 ng/mL or 300 ng/mL on the Alinity c analyzer. The semiquantitative application is for the purpose of enabling laboratories to determine an appropriate dilution of the specimen for confirmation by a confirmatory method such as Liquid Chromatography/Tandem Mass Spectrometry (LC-MS/MS) or permitting laboratories to establish quality control procedures. The assay provides only a preliminary analytical test result. A more specific alternative chemical method must be used to obtain a confirmed analytical result. Gas Chromatography/Mass Spectrometry (GC/MS) or Liquid Chromatography/Tandem Mass Spectrometry (LC-MS/MS) are the preferred confirmatory method. Tests for cocaine metabolite cannot distinguish between abused drugs and certain prescribed medications. Clinical and professional judgment should be applied to any drug of abuse test result, particularly when preliminary results are used. For In Vitro Diagnostic Use Only.
