Geisinger Epic Procedure Code: LAB2146             Geisinger Epic ID: 47478

Specimen type:
Synovial fluid, Bursa fluid
Preferred collection container:
Alternate Collection Container:
Capped syringe
Anaerobic Transport Media (ATM)
Specimen required:
5-10 mL; minimum 1 mL
For volumes < 0.5mL, add fluid to Eswab liquid transport. Do not send swab.
Special notes:
For volumes less < 0.5 mL, collect with Eswab. Check expiration date on transport device before use. See Collection Appendix for collection instructions and use of ATM. When collecting specimen, take precaution to avoid contamination with normal bacterial flora.
Patient preparation:
Use skin disinfection procedure as appropriate.

Specimen processing instructions:
Immediately transport all specimens to the laboratory to optimize bacterial recovery. 
Transport temperature:
Room temperature.
Specimen stability:
ATM or ESwab < 72 hours.
Sterile container or tube: ASAP, < 1 hour optimal.
Rejection criteria:
Improperly labeled/identified specimen. Improperly collected specimens. Expired transport device. Grossly contaminated specimens. Delay in transport or transport at the wrong temperature.

Reference interval:
No growth.
CPT code(s):
87070, 87075, 87205

Test includes:
Isolation, identification and semi-quantitation of aerobic and anaerobic organisms. Semi-quantitation of normal flora, if appropriate. Antibiotic susceptibility testing and bacterial identification performed as appropriate. Additional charges may apply. An additional fee for specimen concentration will be applied.

Optimal microbiology practice and recommendations indicate that a Gram stain is to be performed on all anaerobic culture specimens. For this reason, a Gram stain is included at an additional charge on all specimens for anaerobic culture.

Anaerobe, aerobic, culture, bursal fluid culture, fluid culture, ROUT, ANAR
Clinical significance:
Use to detect the presence of bacteria from a normally sterile specimen type. The best quality specimen is aseptically collected, avoiding contamination with superficial microorganisms.
