|Additional information||HBeAg is a marker of extensive viral replication found almost exclusively in HBsAg-positive sera (in rare mutants not expressing HBsAg, HBeAg can remain positive. Persistently HBeAg-positive patients are more infectious than HBeAg-individuals, more likely to develop chronic liver disease, have less satisfactory results following liver transplantation, and may be candidates for alpha-interferon therapy.
NOTE: HBIG and HBV vaccine are administered to neonates, intimate contacts and recipients of needle sticks on the basis of HBsAg positivity, even if the mother/index case is HBeAg-negative.
Positive results are automatically forwarded to California public health per regulations. However, this does not absolve the ordering provider from any additional reporting if such is required.
