A positive hepatitis B item 1 refers to the first of the five hepatitis B items, called hepatitis B surface antigen. A positive hepatitis B surface antigen indicates that you are currently a hepatitis B patient and is often accompanied by a positive hepatitis B core antibody. In the case of major triplets, this will be accompanied by a positive e antigen, and minor triplets will be accompanied by a positive e antibody. Major triplet and minor triplet are the two most common states of hepatitis B infection in humans. Among the hepatitis B viruses, hepatitis B surface antigen is the outermost component of the intact virus and the most detectable component from the blood circulation after infection, which is hepatitis B surface antigen. Therefore, if the blood can be tested positive for hepatitis B surface antigen, it indicates a state of hepatitis B infection. Hepatitis B infection may or may not cause damage to the liver, so it should be detected by liver function tests, and should also be reviewed regularly.
