The hepatitis B surface antigen is greater than 250, which is not a normal range, because the hepatitis B surface antigen is part of the hepatitis B virus that replicates itself after it infects people, although it is not contagious, but as long as a large amount of hepatitis B surface antigen can be detected in the blood circulation, it means that the body is currently being infected by the hepatitis B virus, and the hepatitis B virus has a large amount of replication in the body. In general, the hepatitis B core antibody will be positive, and in the case of major triplets, it will also be accompanied by positive hepatitis B e antigen, and in the case of minor triplets, it will also be accompanied by positive hepatitis B e antibody, which is the state of chronic infection. Regardless of which items are positive, the DNA quantification of the hepatitis B virus needs to be checked to see what the current DNA quantification of the virus is, and the liver function and liver morphology need to be looked at to determine if there is any damage to the body and how much damage it has caused.
