Used in the differential diagnosis, staging, and prognosis of hepatitis B infection. HBeAg indicates active HBV replication. Infectivity is evaluated based on HBeAg and HBsAg. When HBeAg persists much longer than 10 weeks, the patient is likely to develop chronic hepatitis and be a carrier. See Hepatitis in the Infectious Disease chapter, Interpretive Information section. HBeAb appears in the early convalescence of HBV infection. With carrier state and chronic hepatitis, HBeAb may not develop.
Dietary supplements containing biotin may interfere in
assays and may skew analyte results to be either falsely
high or falsely low. For patients receiving the recommended
daily doses of biotin, draw samples at least 8 hours following
the last biotin supplementation. For patients on mega-doses
of biotin supplements, draw samples at least 72 hours
following the last biotin supplementation.
