Benzodiazepine metabolites may be detected up to 72 hours after ingestion depending upon the specific benzodiazepine. The urine benzodiazepine screening test detects the presence of the benzodiazepine metabolite diazepam at a concentration of 200 ng/mL or greater. Other benzodiazepine metabolites are detected, call laboratory for information regarding a specific benzodiazepine. This method is unable to distinguish between specific benzodiazepines and should be used for screening. Confirmation testing should be considered for positive screens; See Benzodiazepines, Confirmation.Note: These results are for medical purposes only.
