A vaccine is available to prevent hepatitis A. Hepatitis B virus (HBV) is the most common cause of acute viral hepatitis.It is spread through contact with blood or other body fluids from an infected person.Exposure can occur, for example, through sharing of needles for intravenous drug use or through unprotected sex.ome of the tests detect antibodies produced by the immune system in response to the infection and one detects proteins (antigens) that indicate the presence of the virus. A hepatitis panel typically includes: 1  Hepatitis A antibody, IgM. 2  Hepatitis B core antibody, IgM.
