About Hepatitis B Surface Antigen Lab Test in St. Cloud
Hepatitis B Surface Antigen (HBsAg) is a key marker in the evaluation of hepatitis B virus (HBV) infection.
HBsAg appears in the blood before other hepatitis B markers and is typically the first detectable sign of infection. In acute infection, it becomes positive early and usually clears within a few months as the immune system resolves the virus.
When HBsAg remains detectable for longer than six months, the infection is classified as chronic. Chronic hepatitis B can be asymptomatic for years, yet it may lead to progressive liver damage, cirrhosis, or liver cancer, so ongoing monitoring is important.
The test is also used to screen blood donors, pregnant individuals, and people with risk factors for HBV. A positive result is generally followed by additional tests, such as antibody and viral DNA assays, to clarify the stage of infection and guide clinical decisions.
