Pop quiz, when did you last test for Tuberculosis?If it wasn't within the last 4 years, you are due! The Cerro Gordo County Department of Public Health provides Tuberculosis (TB) skin testing for $20. The department also offers free medication through the Iowa Department of Public Health,and case management for anyone requiring latent TB infection treatment in collaboration with the patients’ health care provider. TB Skin tests must be read within 48-72 hours following administration. We recommend a staff member from our department read the test, but another qualified healthcare provider may also read the test.
