AFB Rapid culture by Bactec Fx - Bone Marrow (M)

The AFB Rapid Culture by BACTEC FX – Bone Marrow (M) test is a specialized microbiology test used to detect Acid-Fast Bacilli (AFB), particularly Mycobacterium tuberculosis, in bone marrow samples. The test uses the BACTEC FX automated culture system, which provides rapid and sensitive detection of mycobacterial growth compared with conventional culture methods. It is especially useful for diagnosing disseminated tuberculosis and other mycobacterial infections involving the bone marrow.

This test is recommended for patients with suspected disseminated TB, prolonged unexplained fever, weakened immunity, or when tuberculosis is suspected despite negative routine investigations. A bone marrow sample collected by a qualified healthcare professional is processed in the BACTEC FX system to detect mycobacterial growth. The results help clinicians confirm infection, initiate appropriate anti-tuberculosis therapy, and improve patient outcomes when interpreted alongside clinical findings and other laboratory investigations.
