AFB Rapid Culture-sputum near me in Coimbatore

The AFB Rapid Culture-sputum test measures the growth of mycobacteria in a specialized liquid culture system. The MGIT tube contains a nutrient-rich medium and an oxygen-sensitive fluorescent sensor. As mycobacteria grow and consume oxygen, the fluorescence increases, signaling bacterial presence. This advanced method allows early detection of Mycobacterium tuberculosis (MTB Complex) as well as non-tuberculous mycobacteria (NTM or MOTT), offering faster and more accurate results than conventional solid cultures.

If M. tuberculosis is detected, it means the bacteria have grown in the sample, and the culture can also be used for antibiotic susceptibility testing, as advised by the treating physician. If M. tuberculosis is not detected, it suggests no bacterial growth, and the patient is unlikely to have TB. However, doctors may recommend additional tests, such as PCR, for an accurate diagnosis.
