Hepatitis B Envelope Antigen (HBeAg) Test :
A blood test that detects the presence of the Hepatitis B envelope antigen (HBeAg), a protein produced by the Hepatitis B virus (HBV). The presence of HBeAg indicates active viral replication and high levels of infectivity, meaning the person is more likely to transmit the virus to others. A positive result often signifies that the infection is in its acute or early chronic phase, and close monitoring or treatment may be necessary to manage the infection and reduce complications.
