A high quantitative value of hepatitis B surface antigen indicates that the patient is a hepatitis B carrier. The large quantitative value of hepatitis B surface antigen indicates that the patient has a lot of hepatitis B virus and is highly infectious, and it also indicates that the patient’s viral replication is active and he/she is already a hepatitis B carrier. At this time, patients need to go to the hospital every six months for regular liver checkups, and if high HIV DNA values are found, oral antiviral drugs are needed to inhibit the replication of the hepatitis B virus, so that the development of liver fibrosis and cirrhosis can be slowed down. Besides, because the blood of hepatitis B carriers contains relatively intact virus particles that may infect others, hepatitis B carriers cannot donate blood. Alcohol consumption should be avoided as much as possible during the recovery period so that acetaldehyde does not damage the liver cell membranes. When the quantitative value of hepatitis B surface antigen is large, you should follow the doctor’s advice to carry out the relevant treatment.
