HEPATITIS B SURFACE ANTIGEN (HBSAG)

The Hepatitis B Surface Antigen (HBsAg) test is used to detect the presence of the hepatitis B virus (HBV) in the body. A positive result indicates that a person is infected with HBV and can transmit the virus to others, either through acute or chronic infection. This test is commonly used for screening, diagnosing and monitoring hepatitis B, especially in individuals at high risk or showing symptoms of liver disease.
