Tuberculosis (TB)

What is TB?

Tuberculosis (TB) is a contagious disease spread by person-to-person contact. TB is caused by bacteria that can invade any organ of the body, most commonly the lungs.

TB Skin Testing

The TB skin test (“Mantoux”) is done by injecting a small quantity of testing fluid underneath the skin of your forearm. You must return to the health department within 48-72 hours to have the testing site examined. Failure to return within 48-72 hours will result in invalid results and the test will have to be repeated. Some agencies require a two-step TB skin test. This means that a week after reading the results of the first TB skin test, you would need to come back in again and repeat the entire process as a double-check.

Check the Health Department Fee Schedule for cost.

It is available to all residents of Winnebago County.

For more information on TB skin testing or to schedule an appointment, please call Winnebago County Health Department at 232-3000.
