Test ID: MMLRG    
Antimicrobial Susceptibility, Acid-Fast Bacilli, Rapidly Growing

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.

CTB / Mycobacteria and Nocardia Culture or CTBID / Culture Referred for Identification, Mycobacterium and Nocardia must also be ordered and will be charged separately unless identification of organism is provided.

 

Specimen Type: Organism

Container/Tube: Middlebrook 7H10 agar slant or other appropriate media

Specimen Volume: Pure isolate

Collection Instructions:

1. Organism must be in pure culture, actively growing.

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

Additional Information:

1. Specimen source and suspected organism identification are required.

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.
