The Hepatitis B Envelope Antigen (HBeAg) test is a crucial tool for understanding your Hepatitis B infection. HBeAg is a viral protein produced when the virus is actively replicating in your liver. A simple blood sample allows the lab to detect this antigen, showing whether the virus is highly active and how infectious you may be. A positive result indicates ongoing viral replication, which helps your doctor assess disease severity, monitor progression, and decide on the need for antiviral treatment. This test provides critical, real-time information, guiding timely, targeted care to protect your liver health.
