Special Instructions: Gram stain included with culture and has a separate charge. There will be separate charges for organism identification and susceptibility testing when appropriate. If Neisseria gonorrheae is suspected ask for GC culture to be included. Specimens sent from OR will be cultured for aerobes and anaerobes. Other specimens with a high suspicion of anaerobic bacteria should have a note made on the lab requisition and specimen should be sent in anaerobic transport media.
