HelpTest ID: HEAB Hepatitis B e Antibody, Serum
Reporting Name
HBe Antibody, SUseful For
Determining the presence or absence of detectable hepatitis B e antibody in monitoring infection status of individuals with chronic hepatitis B
Determining infectivity of hepatitis B virus (HBV) carriers
Monitoring serologic response of chronically HBV-infected patients receiving antiviral therapy
Clinical Information
During recovery from acute hepatitis B, the hepatitis B e antigen (HBeAg) level declines and becomes undetectable and HBe antibody (anti-HBe) appears in the serum. Anti-HBe usually remains detectable for several years after recovery from acute infection.
In hepatitis B virus (HBV) carriers and in patients with chronic hepatitis B, positive anti-HBe results usually indicate inactivity of the virus and low infectivity of the patients. Positive anti-HBe results in the presence of detectable HBV DNA in serum indicate active viral replication.
For more information, see the following:
-Hepatitis B: Testing Algorithm for Screening, Diagnosis, and Management
Interpretation
Absence of hepatitis B e antigen (HBeAg) with appearance of HBe antibody (anti-HBe) is consistent with inactivity of the virus and loss of hepatitis B virus (HBV) infectivity.
Although resolution of chronic HBV infection generally follows the appearance of anti-HBe, the HBV carrier state may persist.
