Specimen Collection Manual and Test Catalog
CULTURE, SINUS, AEROBIC AND ANAEROBIC
Geisinger Epic Procedure Code: LAB2145 Geisinger Epic ID: 47518Maxillary sinus, sphenoid sinus, ethmoid sinus, frontal sinus.
Sinus contents: As much as possible; minimum 1 mL.
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.
Immediately transport all specimens to the laboratory to optimize bacterial recovery.
Room temperature.
Eswab: < 72 hours.
Sterile container: < 24 hours.
Anaerobic Transport Media: < 72 hours
Improperly labeled/identified specimen. Improperly collected specimens. Expired transport device. Grossly contaminated specimens. Delay in transport or transport at the wrong temperature.
No growth. Normal flora, if applicable.
The CPT codes provided by GML are based on AMA guidelines and are for informational purposes only.
Isolation and identification of aerobic and anaerobic 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, anaerobic, culture, respiratory, ANAR, SINCAA
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.
