Tuberculosis, also called TB, is an infection caused by a bacteria. TB usually affects the lungs, but it can spread to the kidneys, bones, spine, brain, and other parts of the body. The most commonly used skin test to check for TB is the PPD â purified protein derivative. If you have a positive PPD, it means you have been exposed to a person who has tuberculosis and you are now infected with the bacteria (mycobacterium tuberculosis) that causes the disease. Not necessarily.
To perform two-step testing, a second skin test is placed 1-3 weeks after the initial skin test, if the first test is negative. If the second test remains negative, the person is presumed to be negative for latent tuberculosis, and any subsequent positive tests are the result of new infection. If the second test turns positive, this is a boosted response from prior TB infection.
