Culture, Anaerobic with Gram Stain, Joint Fluid

Test Code
37008


Preferred Specimen
3 mL or 3 grams joint fluid/tissue collected in an anaerobic transport gel vial for fluid and tissue specimens or anaerobic transport swab with Amies gel (blue-cap) or ESwab (white-cap)


Minimum Volume
1 mL or 1 gram


Instructions
Tissues and fluids are superior to a swab specimen. If swabs must be used, collect 2 anaerobic transport swabs, one for culture and one for gram stain OR one ESwab (white-cap) for both culture and gram stain. Specimens not listed as acceptable may be processed for anaerobic culture only after consultation with a Quest Microbiology Scientific Director.
Do not submit syringe with needle attached. If submitting syringe, remove needle, expel air and cap syringe. Purulent sterile body fluids not submitted in an anaerobic transport tube may be accepted for culture if received within 8 hours of collection.

Clinical Significance
Anaerobic bacteria cause a variety of human infections. The results of anaerobic cultures assist the clinician with diagnosis and treatment of patients with anaerobic infections. This culture is incubated for a total of 14 days to allow for low organism level and slow growing organisms, especially significant with joint infections.
