The answer is: C
Anti-HBs is the protective antibody in hepatitis B virus infection. Persons with anti-HBs are protected against reinfection with the virus. None of the other antibodies are protective. However, anti-HBe and HBC are commonly measured to gauge the progress of the infection or determine the status of a patient with a viral hepatitis. |
