Laboratory assay overview
Detect presence of benzodiazepine class drugs
Labcorp test directory, test code 791886
Laboratory assay overview
Benzodiazepines are widely used as anxiolytics, sedative- hypnotics, muscle relaxants, and anticonvulsants. Benzodiazepines include drugs such as diazepam Valium®, chlordiazepoxide Librium®, oxazepam Serax®, lorazepam Ativan®, alprazolam Xanax®, clonazepam Clonopin® and triazolam Halcion®. Many common benzodiazepines are detected in urine by their metabolites oxazepam and nordiazepam. Psychological and physiological addictions, misuse and abuse of benzodiazepines have been described.

Quest Diagnostics test directory, test code 90853
Laboratory assay overview
Diazepam is effective in the management of generalized anxiety disorder and panic disorder in appropriately selected patients. Its use prior to endoscopy or cardioversion relieves anxiety and diminishes the patient's recall of the procedure. Preoperative use relieves anxiety and tension and may provide anterograde amnesia. Additional uses include the treatment of skeletal muscle spasms due to inflammation or trauma, spasticity (eg, multiple sclerosis, cerebral palsy, paraplegia, stiff-man syndrome), seizure disorders (eg, status epilepticus, febrile seizures), and alleviation of abstinence symptoms during alcohol withdrawal.
Therapeutic: diazepam + nordiazepam: 0.2−2.5 μg/mL

We compile every detail above directly from named laboratory directories and published clinical studies. Laboratories calculate standard reference intervals from the statistical distribution of tested populations for a specific assay method and demographic group, rather than setting universal optimal targets.
