Tuberculin Skin Test
A test performed by injecting purified protein derivative (PPD) extract
under the skin. A person who receives this test must return to his
or her health care provider after 48 to 72 hours so that the skin’s
reaction can be evaluated. A hard red bump or a swollen area at
the injection site indicates that the person has been exposed to
the bacterium that causes tuberculosis (TB). Additional tests are
required to determine if the person has active TB infection.

Tuberculosis (TB)
An infection caused by the bacterium Mycobacterium tuberculosis.
TB bacteria are spread through the air when a person with active
TB coughs, sneezes, or speaks. Breathing in the bacteria can lead
to infection in the air sacs of the lungs. Symptoms of TB in the
lungs include cough, tiredness, weight loss, fever, and night sweats.
Although the disease usually occurs in the lungs, it may also affect
the larynx, lymph nodes, brain, kidneys, or bones. A person with
T both TB and HIV is more likely to develop tuberculosis disease than
a person infected only with the TB bacterium, and TB is considered
an AIDS-defining condition in people with HIV.
