Ordering Recommendation

Reflex panel to identify anaerobic bacterial isolate and determine in vitro susceptibility to antimicrobial agents.

New York DOH Approval Status

This test is New York state approved.

Specimen Required

Patient Preparation

Actively growing organism, in pure culture

Specimen Preparation

Transport sealed container with pure culture on agar slant in anaerobic transport pouch or on a swab in anaerobic transport media. Place each specimen in an individually sealed bag.

Storage/Transport Temperature

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 pathogen.


Ambient: 72 hours; 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


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. An additional processing fee will be billed for all mixed cultures, as indicated in the specimen requirements. Although, susceptibility testing is not automatically performed on isolates of unknown clinical significance, testing may be requested by contacting the laboratory.

Submission of mixed cultures will result in delayed turnaround time and increased charges. Isolation of organism should be ensured prior to submission.  Order a separate test for each organism identification required.

Avoid submission of isolates in liquid media where possible. Submission of liquid media commonly results in mixed and/or non-viable cultures.

Anaerobe susceptibility testing is appropriate in the case of serious infections involving blood, bone, joint, tissue, or brain abscess. (Refer to Antimicrobial Susceptibility - Anaerobe, ARUP test code 0060202).

For identification by 16s rDNA sequencing only, order Organism Identification by 16s rDNA Sequencing (ARUP test code 0060720).
