Antimicrobial Susceptibility, Anaerobic Bacteria, MIC

Testing Algorithm Delineates situations when tests are added to the initial order. This includes reflex and additional tests.

When this test is ordered the reflex tests may be performed and charged separately. All bacterial organisms submitted will automatically have susceptibility testing performed and billed as appropriate. Antimicrobial agents appropriate to the organism and specimen source will be tested.


See Anaerobic Bacteria Antimicrobials in Special Instructions to review the table which provides a listing of the antimicrobials routinely tested in our laboratory as well as antimicrobials that may be tested upon request. Contact Mayo Medical Laboratories at 800-533-1710 and ask to speak to the Bacteriology Anaerobe Laboratory if the organism or antimicrobial of interest is not listed in this table.


Anaerobe Suscep Battery will routinely be tested and billed. If fewer than 3 antibiotics will be reported, then Anaerobe Suscep Battery will be canceled and Anaerobe Suscep per agent will be charged per antibiotic. Based on susceptibility criteria, Beta Lactamase and/or Anaerobe Suscep per agent may be performed at an additional charge.

Specimen Type Describes the specimen type validated for testing


Shipping Instructions

See Infectious Specimen Shipping Guidelines in Special Instructions for shipping information.

Necessary Information

Organism identification and specimen source are required for processing.

Specimen Required Defines the optimal specimen. This field describes the type of specimen required to perform the test and the preferred volume to complete testing. The volume allows automated processing, fastest throughput and, when indicated, repeat or reflex testing.


Anaerobic transport tube (T588)

Thioglycollate broth or any other suitable anaerobic transport system

Large infectious container (T146)


Specimen Type: Organism in pure culture

Acceptable Sources: Available on isolates from blood cultures, bone and joint infections, or brain abscesses and organisms isolated in pure culture from other sources


Preferred: Anaerobic transport tube (T588)

Acceptable: Thioglycollate broth or any other suitable anaerobic transport system

Collection Instructions:

1. Organism must be in pure culture, actively growing. Do not submit mixed cultures.

2 Place specimen in a large infectious container (T146) and label as an etiologic agent/infectious substance, if appropriate.


If not ordering electronically, complete, print, and send a Microbiology Test Request Form (T244) with the specimen (

Reject Due To Identifies specimen types and conditions that may cause the specimen to be rejected








Agar plate

Specimen Stability Information Provides a description of the temperatures required to transport a specimen to the laboratory. Alternate acceptable temperatures are also included.
