Primarily to screen for and diagnose acute or chronic hepatitis B virus (HBV) infection, to detect a previous, resolved hepatitis B infection, or sometimes to guide and monitor treatment.

 

Hepatitis B is an infection of the liver caused by the hepatitis B virus (HBV). Hepatitis B blood tests detect viral proteins (antigens), the antibodies that are produced in response to an infection, or detect or evaluate the genetic material (DNA) of the virus. The pattern of test results can identify a person who has a current active infection, was exposed to HBV in the past, or has immunity as a result of vaccination.
