Mycobacteria, Culture, Smear, Identification, and Susceptibility
Use
Identification of Mycobacteria to species level, including Mycobacterium tuberculosis complex and nontuberculous species, is critical for appropriate antimicrobial therapy and infection control, as different species have distinct treatment regimens and epidemiology. Culture and smear combined with identification and susceptibility testing enable definitive diagnosis and drug sensitivity profiling to guide effective clinical management.
Special Instructions
Not provided.
Limitations
Identification and susceptibility testing rely on organism isolation; nonviable or contaminated specimens may lead to failure. Culture requires extended incubation for slow-growing species, resulting in long turnaround. Additional charges may apply if further identification (e.g., sequencing) is required. Negative cultures do not rule out infection in paucibacillary specimens.
