The Hepatitis B Core Antibody Test detects antibodies against the core antigen of Hepatitis B virus, indicating past or current infection.

The test is used to diagnose Hepatitis B infection, assess immune response, and guide further testing.

No special preparation is needed. You can eat and drink normally. Inform your healthcare provider about any medications or recent health issues.

Results are typically available within 1 to 2 days after the test.

A positive result indicates past or current exposure to Hepatitis B virus. It may require further testing to determine the infection stage and appropriate management.

Risks include mild discomfort, potential infection, and, rarely, injury to the urethra or bladder.
