Geisinger Epic Procedure Code: LAB2144         Geisinger Epic ID: 47516

Specimen type:
Maxillary sinus, sphenoid sinus, ethmoid sinus, frontal sinus.
Preferred collection container:
Alternate Collection Container:
Anaerobic Transport Media (ATM)
Specimen required:
Sinus contents: As much aspossible; minimum 1 mL.
Special notes:
Specimens from nasal drainage or nasopharyngeal cultures usually do not correlate well with true sinus infection. Therefore, direct needle aspirate of the sinus is the specimen of choice.

Specimen processing instructions:
Immediately transport all specimens to the laboratory to optimize bacterial recovery. 
Transport temperature:
Room temperature.
Specimen stability:
Eswab: < 72 hours.
Sterile container: < 24 hours.
Anaerobic Transport Media: < 72 hours
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. Normal flora, if applicable.
CPT code(s):
87070, 87205

Test includes:
Isolation and identification of aerobic pathogens. Semi-quantitation of normal flora if appropriate. Antibiotic susceptibility testing and bacterial identification performed as appropriate. Additional charges may apply.

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

Aerobic, culture, respiratory, ROUT
Clinical significance:
Isolation of potential respiratory pathogens can be useful in the diagnosis of sinus tract infection. The significance of any isolate must be evaluated when normal pharyngeal flora is present.
