What is HBeAg test?

The HBeAg test detects the presence of hepatitis B e antigen (HBeAg) in the blood, which indicates active replication of the hepatitis B virus (HBV) and higher infectivity. A positive HBeAg result suggests that the virus is actively multiplying, while a negative result may indicate a lower level of viral activity. This test is often used to assess the stage of hepatitis B infection and guide treatment decisions. Additionally, monitoring HBeAg can help evaluate the effectiveness of antiviral therapy.
