Test Code
AFBID


Quest Code
92186


Includes
If the organism cannot be identified by the original method, then additional charges will be added for each organism: (CPT code(s) 87153: AFB Sequencing).

If TB is isolated for the first time or after three months after the first isolate from a patient, then susceptibilities will be performed at an additional charge (CPT code(s): 87190 per drug).
If M. avium complex (MAC), M. abscessus complex, M. chelonae, M. fortuitum group, M. kansasii, or M. marinum are isolated, then appropriate susceptibilities will automatically be performed at an additional charge (CPT code(s): 87186 per organism).
If other Mycobacteria species are isolated, then appropriate susceptibilities can be performed at an additional charge if requested (CPT code(s): 87186 per organism).


Preferred Specimen
Pure isolate collected on an agar slant in a double-walled container


Other Acceptable Specimens
Positive broth bottle or tube


Instructions
Stability of isolates will be determined by the laboratory. Organism must be viable.
For Nocardia Identification refer to test code 34118 - Bacterial Identification, Aerobic


Transport Container
Double-walled container


Transport Temperature
Room temperature


Specimen Stability
Room temperature: 30 days
Refrigerated: 30 days
Frozen: Unacceptable


Methodology
Matrix Assisted Laser Desorption Ionization-Time of Flight • Sequencing

Reference Range
See Laboratory Report


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
