Aerobic Organism Identification with Reflex to Susceptibility
Ordering Recommendation
Identification. Methods may include biochemical, mass spectrometry, or sequencing.
New York DOH Approval Status
This test is New York DOH approved.
Specimen Required
Patient Preparation
Actively growing organism, in pure culture.  
Specimen Preparation
Transport sealed container with pure culture on agar slant or on a swab in bacterial transport media. Place each specimen in an individually sealed bag.  
Storage/Transport Temperature
Room temperature. If culture is suspected of being a microorganism listed as infectious substance affecting humans on IATA list, submit specimen according to Biological Substance, Category A, shipping guidelines.  
Unacceptable Conditions
Mixed cultures or non-viable organisms.  
Specimen source required. Indicate suspected pathogen. For suspected agents of bioterrorism, Salmonella or Shigella, notify your state department of health and refer isolates to your state laboratory for identification. Susceptibilities on agents of bioterrorism are not performed at ARUP.  
Ambient: 1 week; Refrigerated: Unacceptable; Frozen: Unacceptable  
Reference Interval
Complete identification, with susceptibility of clinically significant isolates.
Interpretive Data
An additional processing fee will be billed for all mixed cultures, as indicated in the specimen requirements. Testing performed and associated charges billed depends on specimen source and type of organism suspected. If a significant organism is identified, then the appropriate susceptibility panel will be added. Additional charges apply.

For identification of Shiga-like toxin producing E. coli order test E. coli Shiga-like toxin by EIA (ARUP test code 0060047).
CPT Code(s)
87077 and/or 87153; CPT codes for identification and susceptibility vary based on method.
