HEPATITIS B ANTIGENS Meaning and
Definition
-
Hepatitis B antigens refer to proteins or substances produced by the hepatitis B virus (HBV) that can trigger an immune response in the body. These antigens are important for diagnosing and monitoring hepatitis B infection, as well as for the development of vaccines and therapies.
There are several types of hepatitis B antigens, including surface antigens (HBsAg), core antigens (HBcAg), and e antigens (HBeAg). HBsAg is the most commonly used antigen for screening and diagnosing hepatitis B infection. It is present on the surface of the virus and in the blood of infected individuals. The presence of HBsAg indicates an ongoing hepatitis B infection.
HBcAg is found within the core of the hepatitis B virus. It is not detectable in the blood of infected individuals but can be detected using specialized laboratory tests. The presence of HBcAg indicates an active infection and is often used as a marker for recent or acute infection.
HBeAg is a soluble antigen that is found in the blood of individuals with an active HBV replication. Its presence indicates a higher risk of transmission, as the virus is more likely to be present and replicating in the body. HBeAg status is important in determining the treatment course for hepatitis B.
Overall, hepatitis B antigens play a vital role in the diagnosis, monitoring, and management of hepatitis B infection. They also contribute to the development of vaccines and antiviral therapies aimed at preventing and treating hepatitis B.
