HEPATITIS B SURFACE ANTIGEN (HBSAG)

The hepatitis B surface antigen (HBsAg) test detects the presence of HBsAg in the blood, indicating an active hepatitis B infection. This test is used to diagnose hepatitis B, assess the infectiousness of an individual, and guide treatment decisions. A positive result suggests a current infection and the potential to transmit the virus. The test is valuable for screening for hepatitis B, monitoring the progression of the disease, and evaluating the effectiveness of treatment. It provides important information for managing hepatitis B infection and implementing public health measures to prevent its spread.
