Room temperature. If culture is suspected of being a microorganism identified on the IATA list as an infectious substance affecting humans, submit specimen according to Infectious Substance, Category A, shipping guidelines.

Unacceptable Conditions

Mixed cultures or non-viable organisms.


Specimen source required.  Indicate suspected pathogens. 


Ambient: 1 week; Refrigerated: Unacceptable; Frozen: Unacceptable


Methods may include biochemical, mass spectrometry, or sequencing





Reference Interval

Complete identification, with susceptibility of clinically significant isolates.

Interpretive Data

Compliance Category

Depends on Specimen/Source/Method


For suspected agents for 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.

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. However, susceptibility testing will not automatically be performed on isolates of unknown clinical significance; testing may be requested by contacting the laboratory. 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).
