Specimen Requirements:

4.0 mL Whole Blood in a Green Top Tube - Na Heparin
Minimum Volume: 1.0 mL
Temperature & Stability: 1 day Ambient
Reference Range: Refer to Interpretive Results
Test Comments: If culture is positive for Mycobacterium species, it will reflex to #2935 AFB Identification by DNA (GenProbe) or #5648 AFB Identification by HPLC at an additional charge. 
If M. tuberculosis complex isolated, susceptibility testing will be performed and a fee will be charged. 
For other Mycobacterium species, susceptibility testing will be performed upon request.
Methodology: Culture
Clinical Significance: The laboratory diagnosis of mycobacterial diseases depends on the detection and recovery of AFB from clinical specimens. This assay employs the use of solid media and broth-based media (MGIT) for rapid isolation of Mycobacterium species. Identifications are performed by commercial probes, HPLC, and/or conventional methods. Susceptibilities for M. tuberculosis and M. avium-intracellulare complex (MAC) are performed by the radiometric method and all others by conventional methods.
