Evaluate the Exposed Person

The exposed person should be evaluated within two hours after exposure to determine his/her HBV vaccination and response status; and, to establish the HIV status at the time of exposure (baseline), the exposed person should be tested for HIV.³⁰ Antiretroviral postexposure prophylaxis (PEP) should not be delayed while waiting for test results. Once the source patient is determined to be HIV-negative, PEP should be discontinued, and no follow-up HIV testing for the exposed provider is indicated.¹⁹
