Hepatitis B surface antigen 2.3 indicates infection with the hepatitis B virus. At present, most of the hepatitis B cannot be completely cured, only some of the acute hepatitis B virus infection may be cured. Hepatitis B surface antigen 2.3, which is already greater than the normal range of 0.05, indicates that you have been infected with the hepatitis B virus. If the person is chronically infected with hepatitis B virus, it is very difficult to be cured and basically carries the hepatitis B virus for a long time. Some people with acute hepatitis B virus infection have a course of less than six months and have a certain degree of self-healing, so it is possible to be cured or get better on their own. Hepatitis B surface antigen is one of the five indicators of hepatitis B. If it exceeds the normal range, regular biochemical and histologic tests are needed. Early intervention is needed at the onset of the disease to improve the condition through hepatoprotective and antiviral therapy. Although there is no complete cure for hepatitis B, the progression of the disease can be controlled and symptoms improved through treatment. Hepatitis B carriers with normal liver function need regular medical checkups and do not need antiviral treatment for the time being. If the liver function indicates that the transaminase is more than twice the normal range, the condition can be controlled by effective antiviral treatment. Specific treatment needs to be carried out under the guidance of a doctor.
