Culture Referred for Identification, Mycobacterium and Nocardia, Varies
Useful For 
Suggests clinical disorders or settings where the test may be helpful
Rapid identification to the species level for Mycobacterium species, Nocardia species, and other aerobic actinomycete genera and species from pure culture isolates
Highlights
Nucleic acid probes used for identification, when applicable, include those for Mycobacterium avium-intracellulare complex, Mycobacterium gordonae, and Mycobacterium tuberculosis complex.
Matrix-assisted laser desorption ionization time-of-flight mass spectrometry 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 Mycobacterium tuberculosis complex will be further identified to the species level upon request, using rapid polymerase chain reaction testing.
Reflex Tests Lists tests that may or may not be performed, at an additional charge, depending on the result and interpretation of the initial tests.

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 test may be performed at an additional charge. All mycobacteria and Nocardia (including aerobic actinomycetes) submitted will be identified and billed as appropriate.
