CULTURE, EAR, AEROBIC

Geisinger Epic Procedure Code:  LAB2130    Geisinger Epic ID:  47504

SPECIMEN COLLECTION
Specimen type: 

Aspirate, drainage, outer ear, inner ear, middle ear. 
NOTE: If skin source (e.g., earlobe), order Culture, Wound, Superficial, Aerobic.


Preferred collection container: 
Alternate collection container: 
Amies or Liquid Stuarts Swab
Specimen required: 

One swab. Aspirates: As much as possible; larger volumes may improve culture sensitivity.


Special notes: 

Eswab is the preferred collection device for most ear cultures. A small sterile container may be used for aspirates. Check expiration date on transport device before use. When collecting specimen, take precaution to avoid contamination with normal bacterial flora.


Patient preparation: 

Use skin disinfection procedure as appropriate.



SPECIMEN PROCESSING
Processing instructions: 

Immediately transport all specimens to the laboratory to optimize bacterial recovery.


Transport temperature: 

Room temperature.


Specimen stability: 

Eswab/Other swab: < 72 hours. 
Sterile container: < 24 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.



TEST DETAILS
Reference interval: 

No growth. Normal flora, if applicable.


CPT code(s):  87070, 87205
Note: The billing party has sole responsibility for CPT coding.  Any questions regarding coding should be directed to the payer being billed.

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 deep specimens. For that reason, a Gram stain is included at an additional charge with this culture.


Methodology: 
Culture
Synonyms: 

Aerobic, culture, eardrum, tympanocentesis, ROUT, EARCA


Clinical significance: 

Significance is determined by relating the growth of a particular microorganism to a specific body site/disease.
