High hepatitis B virus but normal liver function requires treatment. If hepatitis B virus is detected but liver function is normal, antiviral therapy is required if HBV-related loss of function has occurred, such as cirrhosis, liver failure, and hepatitis B transplantation with hepatic immunosuppression. Antiviral therapy is also required if there is inflammation on histologic examination of the liver or if there is significant evidence of hepatic fibrosis. Antiviral therapy is required for a family history of hepatitis B, cirrhosis, and age greater than 30 years. Age greater than 30 years, non-invasive techniques for determining hepatic fibrosis or liver histology suggestive of significant hepatic inflammation or fibrosis. Hepatitis B-related extrahepatic manifestations, compensated cirrhosis, etc. require antiviral therapy. In summary, hepatitis B virus high liver function is normal, need to improve the liver elastic fiber measurement, liver biopsy and other tests, if necessary, with the doctor to start the appropriate treatment.
