Order Hepatitis B Surface Antigen Lab TestThe Hepatitis B Surface Antigen lab test detects a protein that appears on the outer shell of the hepatitis B virus. Its presence in blood is the earliest serological marker of infection and remains a key tool for distinguishing acute from chronic cases.
About Hepatitis B Surface Antigen Lab Test in Poway
This test looks for a specific viral protein rather than antibodies, which makes it a direct indicator of hepatitis B virus in the bloodstream.
Hepatitis B surface antigen, often abbreviated HBsAg, is a protein component of the virus's outer envelope. When the virus is actively replicating, this antigen circulates in the blood and can be detected before the body mounts a measurable antibody response.
Because HBsAg appears early and persists for varying lengths of time, it serves as the primary screening marker for hepatitis B infection. A positive result generally prompts additional testing to determine whether the infection is acute or chronic, and to assess liver function and viral activity.
The test requires a standard blood draw, and results are typically reported within one to three business days. Interpretation should always be made by a qualified healthcare professional, who can consider the result alongside other clinical findings and additional hepatitis markers.
