Tuberculosis (TB) Testing

TST (Mantoux) is an injection of a very small amount of fluid in the forearm. A client must return in 48-72 hours after the injection to have the skin test results read by the clinic nurse. At that time written results are given. If the test is positive, further tests need to be done to determine if you actually have Tuberculosis disease which may be communicable to others.


TB tests are given on Mondays, Tuesdays, Wednesdays, and Fridays at the Grant County Health Department. If the test is positive, the patient will be educated on the medications needed to treat tuberculosis and given medications at no charge to treat their infection.
