AFB Rapid culture by Bactec Fx - Blood (M)

The AFB Rapid Culture by BACTEC FX – Blood (M) test is a specialized microbiology test used to detect Acid-Fast Bacilli (AFB), particularly Mycobacterium tuberculosis and other mycobacterial species, in blood samples. The test utilizes the BACTEC FX automated culture system, an advanced technology that rapidly detects the growth of mycobacteria, providing faster and more sensitive results than conventional culture methods. It is especially useful for diagnosing disseminated tuberculosis (TB) and bloodstream mycobacterial infections, particularly in immunocompromised individuals.

This test is recommended for patients with prolonged unexplained fever, suspected disseminated TB, weakened immune systems, or suspected bloodstream mycobacterial infections. A blood sample is collected under sterile conditions and processed using the BACTEC FX culture system to detect mycobacterial growth. The results help clinicians confirm infection, guide appropriate anti-tuberculosis therapy, and support timely patient management when interpreted together with clinical findings and other laboratory investigations.
