  • Diastat®
  • Diastat® AcuDial™
  • Diazepam Intensol™
  • Valium®

Clinical Use:

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.

Test Information:

This approach to detection of serum or plasma cholinesterase variants does not entirely avoid the problem of variation in reactivity with some atypical enzymes.

Specimen Type:

Serum or plasma

Requested Volume: 

1 mL

Minimum Volume: 

0.4 mL

Container Type: 

Red-top tube, lavender-top (EDTA) tube, or green-top (heparin) tube. Do not use a gel-barrier tube. The use of gel-barrier tubes is not recommended due to slow absorption of the drug by the gel. Depending on the specimen volume and storage time, the decrease in drug level due to absorption may be clinically significant.


Transfer separated serum or plasma to a plastic transport tube. Oral: peak: one hour after dose; IV: peak: 15 minutes after dose.
