The hepatitis B test refers to the clinical hepatitis B triple system, or hepatitis B five-item test, which includes five items: hepatitis B surface antigen, hepatitis B surface antibody, hepatitis B E antigen, hepatitis B E antibody, and hepatitis B core antibody. For normal people, a positive hepatitis B surface antibody may occur after vaccination. This is a normal reaction after vaccination and indicates that the body has self-immunity and is immune to chronic viral hepatitis B and will not be infected with chronic viral hepatitis B. If the patient is a patient with viral hepatitis B, he will have a positive hepatitis B surface antigen. Depending on the patient’s major triplet and minor triplet expressions, the patient will need further blood tests for hepatitis B DNA to see if the virus is replicating, if necessary. If the virus is replicating and there is a combination of liver function impairment, that is, elevated glutathione and glutamic acid aminotransferase. In this case, we should actively consider antiviral therapy and intravenous infusion of liver-protective drugs for hepatoprotective treatment. Patients should be careful not to stay up late, not to strain, and not to drink alcohol in their normal life. Moderately eat more green vegetables to replenish the body’s trace elements, especially more vitamin C-rich foods and fruits, such as grapefruit, oranges, oranges.
