HBs Ag

A positive or reactive outcome in the Hepatitis B surface antigen (HBsAg) test signifies an active infection with the hepatitis B virus. This test accurately detects the presence of the virus’s surface antigen in the blood. When the result is positive, additional testing becomes imperative to distinguish between a recent acute infection and a chronic hepatitis B infection. Importantly, a positive HBsAg result indicates that the individual is currently infectious and has the potential to transmit the hepatitis B virus to others through their blood. This underscores the critical need for follow-up testing and appropriate medical attention to ascertain the infection’s nature and implement necessary interventions for disease management and prevention of further transmission.
