Q:
What Does Hepatitis B Core Antibody Being Positive Mean?

A:
Hepatitis B Core Antibody (anti-HBc) is one of the blood tests available to diagnose hepatitis B. It is produced by the body in response to a part of the hepatitis B virus.

The meaning of this test often relies on the results of two other tests: Hepatitis B Surface Antigen (HBsAg) and Hepatitis B Surface Antibody (anti-HBs).

A positive test has two possible meanings:

  • A person is infected with hepatitis B virus, or
  • A person was infected in the past but the infection has been cleared.
