Hepatitis B: HB Surface Antigen (HBs Ag)

Hepatitis B Surface Antigen (HBsAg) Test in Slough
The HBsAg test is a blood test used to detect the presence of the hepatitis B surface antigen, a key protein found on the surface of the hepatitis B virus (HBV). It is one of the most reliable and earliest markers of hepatitis B infection, commonly used for diagnosis and monitoring.

Understanding HBsAg and Its Role
When an individual becomes infected with HBV, the virus begins to replicate, prompting the immune system to produce HBsAg. This antigen typically appears in the blood within 1 to 10 weeks after exposure. Its presence indicates an active hepatitis B infection, whether recent (acute) or long-standing (chronic).

Importance of HBsAg Testing
HBsAg testing is a crucial tool in the early detection of hepatitis B, allowing healthcare providers to identify infections before complications arise. It also plays a significant role in monitoring chronic HBV cases and evaluating treatment effectiveness.

Comprehensive Hepatitis B Screening in Slough
HBsAg testing is often performed alongside other hepatitis B tests, such as hepatitis B core antibody (HBcAb) and hepatitis B surface antibody (HBsAb). This comprehensive screening helps determine the stage of infection and assess the risk of chronic liver conditions such as cirrhosis or liver cancer.

Who Should Get Tested?
HBsAg testing is essential for individuals at risk of HBV infection, including:

People with symptoms of liver disease

Pregnant women (as part of routine antenatal screening)

Sexual partners of infected individuals

People born in countries with high hepatitis B rates

Healthcare workers and blood donors
