Tuberculosis (TB) Clinic & Screening

Tuberculosis (TB) occurs when you inhale the TB germ when a person with TB disease coughs, sings or speaks. The bacteria usually attacks the lungs, but can attack any part of the body such as the kidney, spine, and brain. Learn more and view local TB data on our TB information page.

Tuberculosis (TB) Skin Tests (TST)

TB skin tests are available. Please call 734-544-6700 for an appointment. 

You must return to the clinic to have your test read within 48 to 72 hours of placement. Test results will not be valid after 72 hours.

If you have had a positive skin test in the past, please tell the receptionist when you call, and ask to speak to a TB nurse. If you have had the BCG vaccine, please ask about available TB blood tests.

Latent TB Infection Protocol

The Washtenaw County Health Department would like to share our protocol and algorithm for the screening, diagnosis, and treatment of latent tuberculosis infection (LTBI) for HIV-negative individuals who are 18 years or older (updated Oct. 2018).

This protocol is intended for the use by our local primary care providers based on guidelines from the Centers for Disease Control and Prevention and United States Preventive Services Task Force. This protocol is endorsed by the Tuberculosis Control Program of the Michigan Department of Health and Human Services. This resource is for informational and educational purposes and is not intended as a substitute for clinical judgment.


The Washtenaw County Health Department Tuberculosis (TB) Control Program has the legal responsibility for preventing and controlling TB in the community by:

  • Identifying and treating persons who have suspect/active TB and ensuring they complete appropriate therapy
  • Identifying and screening contacts of persons with TB to determine whether they have latent TB infection or active disease and providing appropriate treatment
  • Screening high-risk populations to detect persons with latent TB infection and providing appropriate treatment to prevent progression to disease
