About Hepatitis B Surface Antigen Lab Test in Berkeley
The hepatitis B surface antigen test is a core tool for identifying current hepatitis B virus infection.
Hepatitis B surface antigen, often abbreviated HBsAg, appears in the blood during acute infection and is typically the first marker to become detectable. In people who clear the virus, the antigen disappears and antibodies against it develop.
When HBsAg remains detectable for longer than six months, the infection is classified as chronic. Chronic hepatitis B can persist for years and may lead to liver inflammation, cirrhosis, or hepatocellular carcinoma, even when symptoms are absent.
The test is used in several contexts: evaluating symptoms such as jaundice or fatigue, screening people with known risk factors, monitoring individuals with chronic infection, and confirming that donated blood or organs are free of the virus. Results are interpreted alongside other hepatitis B markers, including antibodies and viral DNA, to distinguish acute from chronic infection and to assess immune status.
