How is the diagnosis after the five tests of hepatitis B? Experts say the significance of the five hepatitis B results are as follows: 1. Hepatitis B surface antigen HBsAg positive: indicates infection with the hepatitis B virus. It does not reflect the presence or absence of virus replication, the degree of replication, the strength of infectiousness. 2, hepatitis B surface antibody HBsAb (anti-HBs) positive indicates a protective immune effect against infection with hepatitis B virus. For hepatitis B vaccine recipients, if only this is positive, it should be regarded as a normal phenomenon after hepatitis B vaccination. 3. Hepatitis B e antigen HBeAg positivity indicates strong infectiousness. If it continues to be positive for more than 3 months, there is a tendency of chronicity. 4.Hepatitis B e antibody HBeAb (anti-HBe) positive means that the virus replication is reduced and the infectiousness is weak, but it is not no infectiousness. 5, Hepatitis B core antibody HBcAb (anti-HBc) positive indicates previous infection with hepatitis B virus.
