♤IgG =  chronic infection

● HBeAg = it detected in the serum during Acute or chronic infection

♤ its presence = highly infectivity ( high viral replication)

● Anti-HBe :
♤ its presence  = low infectivity ( low viral repilcation ) 
♤ بيدل على انه المريض حصله
Resloved infection ( recovery ) or immunity ( only natural )
