The Acid-Fast Bacilli (AFB) Stain–Ziehl–Neelsen (Z.N.) method is a specialized microscopic staining technique used to detect tuberculosis (TB) and other mycobacterial infections. This test is crucial for diagnosing pulmonary tuberculosis (TB in the lungs) and extrapulmonary TB (TB affecting other organs such as the brain, lymph nodes, or bones). The test works by staining the bacterial cells, which retain the dye even after an acid wash, distinguishing them as acid-fast bacteria (AFB). It is often used as an initial screening tool before confirming TB with molecular or culture-based methods.
