The state requires health care workers (and others who have direct contact with patients) in licensed health care facilities to have pre-employment health screenings, including a two-step TB skin test (PPD).

Two-step TB skin test

The two-step TB skin test confirms a negative result. If a health care worker was exposed to TB many years ago, it is possible for the first TB skin test to be negative, but the test could “boost” the immune system’s reaction. This would result in the second TB skin test (1-3 weeks after the first) being positive. If the health care worker were never exposed to TB, both TB skin tests would be negative.

Routine screenings for health care workers

In addition to the state requirement for pre-employment TB skin testing, many health care workers are required by the Occupational Safety and Health Act (OSHA) to have routine TB skin tests during their employment. The frequency of the routine testing depends on the risk of exposure to TB.
