Test Details: A typical benzodiazepine urine test can detect benzodiazepines or their break-down products, called metabolites. Urine should be tested for benzodiazepines in suspected overdose cases, or as part of an abused drug program. Liquid chromatography linked to tandem mass spectrometry (LC/MS/MS) provides the ability to identify a range of benzodiazepines which is an attractive method for the confirmation of benzodiazepines following immunoassay screening.
