What is TB?
Tuberculosis (often called TB) is an airborne infection caused by bacterium mycobacterium tuberculosis that usually attacks the lungs, but can attack almost any part of the body.

Repeated exposure to someone with TB disease is generally necessary for infection to take place. TB is usually spread between family members, close friends, and people who work or live together.

Testing for TB Infection

There are two kinds of tests that are used to detect TB bacteria in the body: the TB skin test (TST) and TB blood tests. If you have a positive reaction to either of these tests, you will be given other tests to see if you have latent TB infection or TB disease.
