Madison County Health Department provides screening services for tuberculosis during regular clinic hours. Targeted tuberculosis testing is done by determining if a person has had risk of being infected with the bacteria that causes tuberculosis and if a person has a condition associated with progression from tuberculosis infection to tuberculosis disease.  If no risk is identified, the person will be issued a waiver and screening tests will not be done.  Persons with identified risk are screened with either a skin test or a blood test. 

The TB skin test (also called the Mantoux tuberculin skin test) is performed by injecting a small amount of fluid (called tuberculin) into the skin in the lower part of the arm.  The person given the tuberculin skin test must return to the health department in 48 to 72 hours to have a nurse look for a reaction on the arm.  The nurse will look for a raised, hard area, and if present, measure its size using a ruler.  Redness by itself is not considered part of the reaction. 

TB blood tests (also called interferon-gamma release assays or IGRAs) measure how the immune system reacts to the bacteria that cause TB. 

A positive TB screening test means that the person has been infected with TB bacteria.  Additional tests are needed to determine if the person has latent TB infection or TB disease.  

A negative TB screening test means that the person's blood did not react to the test and that latent TB infection or TB disease is not likely.  

An individual with a positive screening test will be evaluated and a chest x-ray will be done.  If he/she determines the client does not have active TB disease but has latent TB infection, treatment may recommended.  Clients are assessed to determine which medicine is best for their circumstances. The client must return to the health department regularly to be evaluated.   

If a client is diagnosed with active tuberculosis, a nurse will make a home visit each day to give the client their medicine.  Blood tests will be ordered as well as cultures on sputums and follow-up chest x-rays.  The nurse will monitor and evaluate the patient until released from the physician (6 to 12 months).

The TB clinic has been in place since 1972 when the TB sanitarium closed.


The goal of the program is to treat active tuberculosis and stop the spread of this disease to the general public.
