Test Details
Methodology
Competitive chemilumescence immunoassay (CLIA)
Result Turnaround Time
1 - 5 days
Turnaround time is defined as the usual number of days from the date of pickup of a specimen for testing to when the result is released to the ordering provider. In some cases, additional time should be allowed for additional confirmatory or additional reflex tests. Testing schedules may vary.
Use
The presence of antibody to hepatitis Be antigen (anti-HBe) can be used in conjunction with other serological and clinical information to determine the stage and prognosis of hepatitis B infection.

Custom Additional Information
The appearance of anti-HBe in patients who have previously been HBeAg positive indicates a reduced risk of infectivity. Failure of appearance implies disease activity and probable chronicity but patients with HBeAb may have chronic hepatitis. Chronic HBsAg carriers can be positive for either HBeAg or anti-HBe, but are less infectious when anti-HBe is present. HBe can persist for years, but usually disappears earlier than anti-HBs or anti-HBc. Anti-HBe has not been found as the sole serologic marker for hepatitis B infection.
