One and five positive hepatitis B tests, which refer to positive hepatitis B surface antigen and hepatitis B core antibody, respectively, are not a normal range because they signify that one is currently a hepatitis B patient. This is so because the first item is called hepatitis B surface antigen, and a positive surface antigen means that one is currently a hepatitis B patient. The outermost particle of the hepatitis B virus is the hepatitis B surface antigen, and when it infects a person after replication, the smallest particle present in the blood circulation is the hepatitis B surface antigen, so the first item will become positive. The fifth item, the core antibody of hepatitis B, appears only after contact with the core antigen of the hepatitis B virus. Although the amount of core antigen is relatively small and cannot be detected in the body, it can be judged by checking the core antibody of hepatitis B that the core antigen does exist and can determine that the body has indeed been infected with the hepatitis B virus. This is called a small two-positive condition, which is not particularly common in clinical practice. The more common cases are accompanied by a positive e antigen or a positive e antibody, which are the major and minor triplets respectively.
