Determination of resistance of slowly growing mycobacteria to antimicrobial agents
When this test is ordered, susceptibility for slow growers will be performed at an additional charge. Antimicrobials are tested and reported using the Clinical and Laboratory Standards Institute (CLSI) guidelines.(1, 2)
Antimicrobials tested for Mycobacterium avium complex: amikacin, clarithromycin, clofazimine, linezolid, and moxifloxacin.
Antimicrobials tested for all other slowly growing Mycobacterium species: amikacin, clarithromycin, clofazimine, ciprofloxacin, doxycycline, linezolid, minocycline, moxifloxacin, rifabutin, rifampin, and trimethoprim /sulfamethoxazole.
Clofazimine interpretive criterion is not available.
Specimen source and organism identification are required.
Organism must be in pure culture, actively growing.
CTB / Mycobacteria and Nocardia Culture, Varies or CTBID / Culture Referred for Identification, Mycobacterium and Nocardia, Varies must also be ordered and will be charged separately unless identification of organism is provided.
Results are reported as the minimum inhibitory concentration in micrograms/mL.
