Order Hepatitis B Surface Antigen Lab TestThe Hepatitis B Surface Antigen lab test is a blood test that detects a specific protein on the surface of the hepatitis B virus. Its presence is the earliest serological marker of acute hepatitis B infection and can also indicate chronic infection.
About Hepatitis B Surface Antigen Lab Test in Romeoville
This test identifies the hepatitis B surface antigen (HBsAg), a protein that appears on the outer envelope of the virus.
HBsAg is the first detectable marker after exposure to hepatitis B, typically appearing before symptoms or liver enzyme elevations. Its presence confirms that the virus is actively replicating and that the person can transmit the infection to others.
In acute infection, HBsAg usually becomes detectable within weeks of exposure and remains positive for several weeks to months. If HBsAg persists beyond six months, the infection is classified as chronic, which carries long-term risks for liver inflammation, cirrhosis, and hepatocellular carcinoma.
The test is performed on a blood sample and requires no special preparation beyond following the lab's standard instructions. Results are typically available within one to three business days and are interpreted alongside other hepatitis B markers, such as antibodies and viral DNA, to determine the stage of infection.
