Clinical Information (ข้อมูลทางคลินิก):
Mycobacterial disease is known to have affected humans for more than a century and still it continues to be a global health concern. There are several challenges as far as TB is concerned.

Mycobacteremia occurs most often in immunocompromised hosts. The majority of disseminated mycobacterial infections are due to Mycobacterium avium complex but bacteremia can also be caused by other mycobacterial species including, but not limited to, Mycobacterium tuberculosis complex, Mycobacterium kansasii, Mycobacterium fortuitum, Mycobacterium chelonae, Mycobacterium scrofulaceum, Mycobacterium szulgai, and Mycobacterium xenopi.

Mycobacterial blood cultures may be indicated for patients presenting with signs and symptoms of sepsis, especially fever of unknown origin.

Nontuberculous mycobacteria are a type of bacteria found in water and soil. These bacteria are typically harmless. However, when they enter the body, they can cause skin lesions, soft tissue infections, and serious lung problems.
 
Reference Value (ค่าอ้างอิง):
No Mycobacterium spp. isolated
 
Interpretation (การแปลผล):
Positive cultures  will send to referral laboratory for organism identification and susceptiblity testing 

Negative reports are issued after 42 days incubation.
