Acid Fast Bacillus Test
The acid-fast bacillus (AFB) test is a diagnostic method used to detect bacteria that cause infections like tuberculosis. The test involves staining a sample, typically sputum, with special dyes that allow certain bacteria to retain color even after being washed with acid.
This unique property helps identify the presence of acid-fast organisms under a microscope. Accurate detection is crucial for early diagnosis and treatment, helping prevent the spread of infectious diseases.
