Is hepatitis b diagnosed by a liver biopsy?

Hepatitis B is typically diagnosed through blood tests that detect the presence of specific markers, such as hepatitis B surface antigen (HBsAg) and hepatitis B core antibody (HBcAb).

A liver biopsy may be recommended in certain situations to assess the severity of liver damage and determine the stage of fibrosis or cirrhosis in individuals with chronic hepatitis B infection. However, a liver biopsy is not routinely performed for the initial diagnosis of hepatitis B.

Blood tests, along with other non-invasive imaging techniques such as ultrasound or elastography, usually provide sufficient information for managing and monitoring hepatitis B infection.
