A test that can help show if someone has been exposed to tuberculosis previously or are currently affected.
How is it done?
A small amount of tuberculosis protein is injected under the skin, and 48-72 hours after the swelling is measured. Redness and the hard lump are your body's reaction to the antigen protein. This is safe and some people have this test done every year.
Who needs it?
Call it what you want
Purified protein derivative (PPD) testing, Mantoux testing, Tuberculin Skin test (TST) - these are all the exact same test.
Getting ready
