Includes
If TB is isolated for the first time or after three months after the first isolate from a patient, susceptibilities will be performed at an additional charge (CPT code(s): 87190 per drug).
Other mycobacteria susceptibility testing will be performed on request at an additional charge (CPT code(s): 87186).
Other mycobacteria susceptibility testing will be performed on request at an additional charge (CPT code(s): 87186).
Preferred Specimen
Pure isolate collected on an agar slant in a double-walled container

Clinical Significance
There are more than 70 species of mycobacteria of which the primary pathogen is M. tuberculosis. Tuberculosis is a chronic, granulomatous disease caused by M. tuberculosis. Identification, and, if appropriate, antibiotic susceptibility, is required to initiate necessary therapy
