Order Hepatitis B Surface Antigen Lab TestThe Hepatitis B Surface Antigen lab test is a blood test that detects the presence of a specific protein on the outer envelope of the hepatitis B virus. This antigen is the earliest serological marker of an active hepatitis B infection, appearing before other detectable indicators. The test is used to identify acute infection and to help determine whether an infection has become chronic.
About Hepatitis B Surface Antigen Lab Test in Normal
The Hepatitis B Surface Antigen test provides a direct look at whether the hepatitis B virus is currently present in the bloodstream.
Hepatitis B surface antigen, often abbreviated as HBsAg, is a protein found on the surface of the hepatitis B virus. When the virus is actively replicating, this antigen can be detected in the blood. Its presence indicates that a person is infected and can potentially transmit the virus to others.
This test is commonly ordered to evaluate symptoms that may suggest hepatitis, such as fatigue, jaundice, or abdominal discomfort, and to screen individuals who may have been exposed to the virus. It is also used to monitor people with known chronic hepatitis B infection. Because the surface antigen appears early in the course of infection, it is a key tool for identifying acute cases.
A positive result generally means the hepatitis B virus is present. Additional testing is often needed to distinguish between a new acute infection and a chronic one, and to assess liver function or viral activity. A negative result typically indicates that the surface antigen is not detected at the time of testing, though it does not by itself rule out every stage of infection or provide immunity status.
