Test Code

The Hepatitis B Envelope Antigen (HBe-Ag) test measures the presence of the envelope antigen of the Hepatitis B virus (HBV) in blood.

HBe-Ag is a marker of active viral replication and high infectivity. Its presence indicates that the virus is actively multiplying and the patient has a higher risk of transmitting HBV to others. This test is especially important in the evaluation and monitoring of chronic Hepatitis B, assessing disease activity, determining prognosis, and guiding antiviral therapy decisions. Loss of HBe-Ag with the appearance of Anti-HBe (HBe-Ab) is known as seroconversion, which usually suggests clinical improvement.
