Test ID: CTB
Mycobacteria and Nocardia Culture, Varies
Useful For 
Suggests clinical disorders or settings where the test may be helpful
Detection and identification of Mycobacterium species, Nocardia species, and other aerobic actinomycetes
Identification is performed using the Hologic/GenProbe AccuProbes for selected Mycobacterium species, matrix assisted laser desorption ionization-time of flight (MALDI-TOF) mass spectrometry, or 500-base pair 16S rRNA gene sequencing
Mycobacterium tuberculosis complex species identification can be done upon request using rapid polymerase chain-reaction (PCR) targeting the regions of difference (RD) genomic areas
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, a reflex test may be performed at an additional charge.
