The titer of anti-HBc.IgG rise in anti-HBs - positive.
Chronic hepatitis B (1) may have a history of acute hepatitis (often not obvious), (2) clinical performance and abnormal liver function over six months or more (3) continued HBsAg positive more than six months, with the total anti-HBc antibody and the IgG antibody positive activities such as the period for the anti-HBc.IgM be a medium, and low titer positive (4) HBeAg and HBV-DNA and DNAP positive or negative and the three former anti-HBe positive (5) for liver biopsy to further clarify the chronic persistent hepatitis, chronic active hepatitis or chronic lobular hepatitis.
