Comments	Benzodiazepine metabolites may be detected up to 72 hours after ingestion depending upon the specific benzodiazepine. The Siemens Atellica Benz (200) benzodiazepine screening test detects the presence of the benzodiazepine/diazepam at a concentration of 200 ng/mL or greater. Other benzodiazepine 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. For additional information related to drug screening, refer to the Urine Toxicology Chart. Screen components may vary by lab location.
