Test ID: TBIDS    
Culture Referred for Identification, Mycobacterium and Nocardia with Antimicrobial Susceptibility Testing

Rapid identification to the species level and susceptibility testing for Mycobacterium species, Nocardia species, and other aerobic actinomycete genera and species from pure culture isolates

When this test is ordered, the reflex antimicrobial susceptibility test will be performed at an additional charge. All mycobacteria and Nocardia (including aerobic actinomycetes) submitted will be identified and billed as appropriate.

Nucleic acid probes used for identification, when applicable, include those for Mycobacterium avium-intracellulare complex, M gordonae, and M tuberculosis complex. Matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI TOF MS) and/or 16S rDNA sequencing is used for identification, when applicable, for slowly and rapidly growing Mycobacterium species and aerobic actinomycetes (including Nocardia species and Streptomyces species). The M tuberculosis complex can be further identified to the species level upon request, using a separate rapid PCR test. Minimum inhibitory concentration (MIC) determination by either the microtiter broth dilution method or critical concentration testing by broth dilution will be automatically performed as appropriate after species identification.
