The tuberculosis skin test (also known as the tuberculin test or PPD test) is a test used to determine if someone has developed an immune response to the bacterium that causes tuberculosis (TB). TB disease is caused by a bacterium called Mycobacterium tuberculosis. The bacteria usually attack the lungs, but TB bacteria can attack any part of the body such as the kidney, spine, and brain. If not treated properly, TB disease can be fatal.

What are the Symptoms of TB?
The general symptoms of TB disease include feelings of sickness or weakness, weight loss, fever, and night sweats. The symptoms of TB disease of the lungs also include coughing, chest pain, and the coughing up of blood. Symptoms of TB disease in other parts of the body depend on the area affected.

How is TB Spread?
TB germs are put into the air when a person with TB disease of the lungs or throat coughs, sneezes, speaks, or sings. These germs can stay in the air for several hours, depending on the environment. Persons who breathe in the air containing these TB germs can become infected.

What is the Tuberculin Skin Test?
The skin test is used most often. A small needle is used to put some testing material, called tuberculin, under the skin's surface (intradermal). In 48-72 hours, you must return to Passport Health to have your reaction checked/read by a clinician.
