This 50 ng/mL cocaine metabolite urine calibrator is intended to be used for calibrating cocaine - metabolite enzyme immunoassay for qualitative and semu quantltatlve determination of cocaine and its metabolites in human urine.
The assay results obtained with the cocaine metabolite enzyme immunoassay in combination with the use of such calibrator provide only a preliminary analytical result. A more specific alternate method must be used in order to obtain a confirmed analytical result. Gas chromatograph/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.
