Blood Culture, AFB and Fungal
Also known as: MC BLDAF
Use
The Blood Culture, AFB and Fungal test is used for culturing acid-fast bacteria and fungi from blood or bone marrow specimens. This test is particularly helpful in diagnosing infections caused by mycobacteria, including Mycobacterium tuberculosis complex, and various fungal organisms when standard cultures might not detect them. It is a crucial step in identifying and subsequently managing such infections, especially in immunocompromised patients or those with persistent unexplained fevers.

Limitations
The methodology might have limitations in detecting organisms with low metabolic activity or those requiring specific growth supplements not included in the media. Susceptibility testing is performed on positive cultures at an additional charge and should be interpreted with clinical presentation as it may not cover all possible resistance mechanisms.
