This is a blood test for Hepatitis B Core Total Antibodies. This involves testing 3 parts which include HBsAg, HBsAb and HBcAb. All three test results are needed to fully understand whether a person is infected or not.

If your HBsAg test is positive, it means you have a hepatitis B infection and can spread it to others through your blood. Further testing is needed to determine if it's a new or chronic infection.

If your anti-HBs (or HBsAb) test is positive, it means you're protected against hepatitis B. This can be from the vaccine or recovering from a past infection. You're immune and cannot be infected or spread hepatitis B.

If your anti-HBc (or HBcAb) test is positive, it means you had or currently have hepatitis B. The core antibody doesn't provide protection like the surface antibody. To fully understand the results, talk to your healthcare provider for an explanation of your hepatitis B status.
