ZMMLS - Specimen: Antimicrobial Susceptibility, Aerobic Bacteria, MIC

Test Catalog

Test ID: ZMMLS    
Antimicrobial Susceptibility, Aerobic Bacteria, MIC

Testing Algorithm Delineates situation(s) 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 aerobically growing bacteria submitted will automatically have susceptibility testing performed and billed as appropriate. Antimicrobial agent appropriate to the organism and specimen source will be tested.

 

See Special Instructions to review tables that provide a listing of the antimicrobials routinely tested in our laboratory as well as antimicrobials that may be tested upon request. These tables are organized by isolate groups and are not all inclusive. Contact MML and ask to speak to the Bacteriology Antimicrobial Susceptibility Testing Laboratory if the organism or antimicrobial of interest are not listed in these tables.

Specimen Type Describes the specimen type needed for testing

Varies

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.

Mayo Medical Laboratories will not perform susceptibility testing on select agents (eg, Bacillus anthracis, Brucella species, Burkholderia mallei, Burkholderia pseudomallei, Francisella tularensis, and Yersinia pestis). Please consult with your state health department or the CDC regarding antimicrobial susceptibility testing of such isolates.

 

Supplies: T146 Large infectious container

Container/Tube: Agar slant or other appropriate media

Specimen Volume: Organism in pure culture

Collection Instructions:

1. Perform isolation of infecting bacteria.

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

3. Place specimen in a large infectious container (T146) and label as an etiologic agent/infectious substance.

Additional Information:

1. Organism identification and specimen source are required for processing.

2. See Infectious Specimen Shipping Guidelines in Special Instructions

Forms: If not ordering electronically, complete, print, and send a Microbiology Test Request Form (T244) with the specimen (http://www.mayomedicallaboratories.com/it-mmfiles/microbiology_test_request_form.pdf).

Specimen Minimum Volume Defines the amount of specimen required to perform an assay once, including instrument and container dead space. Submitting the minimum specimen volume makes it impossible to repeat the test or perform confirmatory or perform reflex testing. In some situations, a minimum specimen volume may result in a QNS (quantity not sufficient) result, requiring a second specimen to be collected.
