Chronic HBV carriers: positive serum HBsAg and HBV DNA, positive HBeAg or anti-HBe, but with more than 3 consecutive follow-ups within 1 year, serum ALT and AST within normal range, and generally no significant abnormalities in liver histological examination. For those with positive serum HBV DNA, they should be mobilized to undergo liver aspiration for further confirmation of diagnosis and appropriate treatment. 2. Inactive HBsAg carriers: positive serum HBsAg, negative HBeAg, positive or negative anti-HBe, undetectable HBV DNA (PCR method) or below the minimum detection limit, more than 3 consecutive follow-ups within 1 year, and ALT within normal range. Liver histology showed a Knodell’s Hepatitis Activity Index (HAI) <4 or other mild semi-quantitative scoring system lesions. It is clear that normal liver function is not a criterion for the diagnosis of hepatitis B virus carriage, and that a diagnosis of "hepatitis B virus carriage" requires liver aspiration and histopathological examination of the liver for clarification. There are often patients who show positive HBVDNA and normal liver function, but when they have a liver puncture, the liver tissue has more obvious inflammation and fibrosis, and such patients are actually slow hepatitis B. Therefore, for patients with normal liver function and positive HBVDNA (especially high), liver puncture is needed to clarify whether they are hepatitis B virus carriers or slow hepatitis B.
