Does CDC recommend routine pre-exposure anti-HBs testing of all healthcare personnel who were previously vaccinated?

In general, no, but the type of testing (pre-exposure or post-exposure) depends on the healthcare worker’s profession and work setting. The risk for hepatitis B virus (HBV) infection for vaccinated healthcare personnel (HCP) can vary widely by setting and profession. The risk might be low enough in certain settings that assessment of hepatitis B surface antibody (anti-HBs) status and appropriate follow-up can be done at the time of exposure to potentially infectious blood or body fluids. This approach relies on HCP recognizing and reporting blood and body fluid exposures and might be applied on the basis of documented low risk, implementation, and cost considerations. Trainees, some occupations (such as those with frequent exposure to sharp instruments and blood), and HCP practicing in certain populations are at greater risk of exposure to blood or body fluid exposure from an HBsAg-positive patient. Vaccinated HCP in these settings/occupations would benefit from a pre-exposure approach.

Because CDC recommends, as of March 2023, that all adults receive a triple panel screening test for HBV once in their lifetime, it may be practical to conduct the routine triple panel test on any HCP who needs testing and has not had a triple panel screening test.
