Read the full statement (215 words)
The LZI Oral Fluid 6-Acetylmorphine Enzyme Immunoassay is intended for the qualitative and semi-quantitative determination of 6-Acetylmorphine in neat human oral fluid, collected into the LZI Oral Fluid Collector, at the cutoff value of 4 ng/mL. The assay is designed for prescription use with a number of automated clinical chemistry analyzers.
The semi-quantitative mode is for purposes of (1) enabling laboratories to determine an appropriate dilution of the specimen for confirmation by a confirmatory method such as GCMS and LCMS or (2) permitting laboratories to establish quality control procedures.
The LZI Oral Fluid 6-Acetylmorphine Calibrators are for use as calibrators in the qualitative and semi-quantitative calibration of the LZI Oral Fluid 6-Acetylmorphine Enzyme Immunoassay at the cutoff value of 4 ng/mL.
The LZI Oral Fluid 6-Acetylmorphine Controls are for use as assayed quality control materials to monitor the precision of the LZI Oral Fluid 6-Acetylmorphine Enzyme Immunoassay at the cutoff value of 4 ng/mL.
The assay provides only a preliminary analytical result. A more specific alternative chemical method must be used in order to obtain a confirmed analytical result. Gas or liquid chromatography/mass spectrometry (GC/MS or LC/MS) is the preferred confirmatory method. Clinical consideration 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.
