Benzodiazepine (BENZ) Reagent, in conjunction with SYNCHRON® Systems Drugs of Abuse Testing (DAT) Urine Calibrators, is intended for the qualitative determination of benzodiazepines in human urine at a cutoff value of 200 ng/mL, on SYNCHRON Systems.
The Benzodiazepine assay provides a rapid screening procedure for determining the presence of benzodiazepines in urine. This test provides only a preliminary analytical result; a positive result by this assay should be confirmed by another generally accepted non-immunological method, such as thin layer chromatography (TLC), gas chromatography (GC), or gas chromatography/mass spectrometry (GC/MS). 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.
Indications for use as stated in the FDA summary.
