What are they used for?
AFB tests are most often used to diagnose an active tuberculosis (TB) infection. They may also be used to help diagnose other types of AFB infections. These include:
Leprosy, a once feared, but rare and easily treatable disease that affects the nerves, eyes, and skin. Skin often becomes red and flaky, with loss of feeling.
An infection similar to TB that mostly affects people with HIV/AIDS and others with weakened immune systems.
AFB tests may also be used for people who have already been diagnosed with TB. The tests can show if the treatment is working, and whether the infection can still be spread to others.
