If the patient’s blood is drawn to check the three systems of hepatitis B and the surface antigen of hepatitis B virus is positive, it is mostly considered that the patient has been infected with chronic viral hepatitis B. Patients first need to see whether the other items in the hepatitis B tri-system are normal. If the other items are normal and only the surface antigen of hepatitis B virus is positive, it is usually considered that the patient is a carrier. If ghrelin transaminase ghrelin transaminase is normal, the patient’s blood test for hepatitis B DNA suggests that the virus has not replicated, and can continue to be observed. Usually patients should absolutely avoid alcohol, and pay attention to rest, do not stay up late, do not labor. If patients have hepatitis B surface antigen positive, hepatitis B e antibody positive, hepatitis B core antibody positive in hepatitis B three systems, this is mostly called small triple positive. If the patient’s hepatitis B DNA review suggests that there is no replication of the virus and the liver function is normal, it is recommended that the patient continue to observe. If the liver function is abnormal, appropriate hepatoprotective treatment should be considered. In addition, if the patient’s hepatitis B three system suggests that hepatitis B surface antigen is positive, hepatitis B e antigen is positive, and hepatitis B core antibody is positive, at this time, it is mostly called triple triple positive. For patients with triple positive, it is often considered that there is viral replication, and patients’ hepatitis B DNA review often suggests that there is viral replication, and at this time, patients need to consider hepatoprotective treatment and antiviral treatment.
