The Board of Nursing does not have specific regulations or require special certification for the administration or reading of a TB skin test. The appropriately prepared RN or LPN may perform this procedure provided the nurse is educated and competent in the procedure. However, it should be noted that some state and federal regulatory agencies including, but not limited to, the Mississippi State Department of Health and the Occupational Safety and Health Administration (OSHA) require nurses to be certified in the administration and reading of TB skin tests in order for such tests and results to be considered valid.
