Acid-Fast Bacillus (AFB) Tests
Acid-fast bacillus (AFB) is a type of bacteria that causes tuberculosis and certain other infections. Tuberculosis, commonly known as TB, is a serious bacterial infection that mainly affects the lungs. It can also affect other parts of the body, including the brain, spine, and kidneys. TB is spread from person to person through coughing or sneezing.
AFB tests are used to diagnose an active tuberculosis (TB) infection. They may also be used to help diagnose other types of AFB infections.
