Immunalysis Barbiturates Urine Enzyme Immunoassay
The Immunalysis Barbiturates Urine Enzyme Immunoassay is a homogeneous enzyme immunoassay with a cutoff of 200 ng/mL. The assay is intended for use in laboratories for the qualitative and semi-quantitative analysis of Barbiturates in human urine with automated clinical chemistry analyzers. This assay is calibrated against Secobarbital. This in vitro diagnostic device is for prescription use only.
The semi-quantitative mode is for purposes of enabling laboratories to determine an appropriate dilution of the specimen for confirmation by a confirmatory method such as Gas Chromatography/ Mass Spectrometry (GC-MS) or Liquid Chromatography/ Tandem Mass Spectrometry (LC-MS/MS) or permitting laboratories to establish quality control procedures.
The Immunalysis Barbiturates Urine Enzyme Immunoassay provides only a preliminary analytical test result. A more specific alternate chemical method must be used in order to obtain a confirmed analytical result. GC-MS or LC-MS/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.
Immunalysis Multi-Drug Calibrators:
The Immunalysis Multi-Drug Calibrators are intended for in vitro diagnostic use for the calibration of assays for the following analytes: Benzoylecgonine, Methamphetamine, Morphine, PCP, Secobarbital and Oxazepam. The calibrators are designed for prescription use with immunoassays.
Indications for use as stated in the FDA summary.
