About Hepatitis B Surface Antigen Lab Test in Round Lake Beach
This test looks for the hepatitis B surface antigen, a viral protein that appears in the blood during infection.
Hepatitis B surface antigen (HBsAg) is a protein found on the surface of the hepatitis B virus. When the virus is present in the body, this antigen can be detected in the blood, often before symptoms appear or liver enzyme levels rise.
The test is used to screen for hepatitis B infection, to help diagnose acute or chronic cases, and to monitor people who may have been exposed. A positive result generally means the virus is present and the person may be able to transmit it to others.
Results are typically interpreted alongside other hepatitis B markers, such as antibodies and viral DNA, to determine whether an infection is acute, chronic, or resolved. A negative result usually indicates no current infection, though timing and individual health factors can affect interpretation.
