A test that can help show if someone has been exposed to tuberculosis previously or are currently affected.
Other names include: Mantoux Test, Purified Protein Derivative (PPD), Tuberculin Skin test (TST) or Tuberculosis (TB) Skin Test
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 a 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?
People who are at a high risk of TB exposure (ie. working in a hospital or clinic) or employment purposes or school admission requirements.
