The LZI Carisoprodol Metabolite (Meprobamate) Enzyme Immunoassay is intended for the qualitative and semi-quantitative determination of carisoprodol metabolite (meprobamate) in human urine at a cutoff value of 100 ng/mL when calibrated against meprobamate. The assay is designed for prescription use with a number of automated clinical chemistry analyzers.

The semi-quantitative mode is for purposes of enabling laboratories to determine an appropriate dilution of the specimen for verification by a confirmatory method such as GC/MS, LC/MS or permitting laboratories to establish quality control procedures.

The assay provides only a preliminary analytical result. A more specific alternative chemical confirmatory method (e.g., gas or liquid chromatography and mass spectrometry) must be used to obtain a confirmed analytical result. Clinical consideration and professional judgment must be exercised with any drug of abuse test, particularly when the preliminary test result is positive.

Indications for use as stated in the FDA summary.
