Chronic hepatitis B is also clinically referred to as hepatitis B. Some patients may have some misconceptions about negative or positive test results, believing that either one of them must be a bad sign, indicating the presence of some disease in the organism. However, in fact, for hepatitis B surface antibodies, whether the test result is negative or positive, it is generally a normal condition. When hepatitis B surface antibody is negative, it means that the patient has not been infected with the hepatitis B virus and has not been vaccinated. A positive hepatitis B surface antibody indicates the presence of antibodies to the hepatitis B virus in the body, which may be caused by the body producing protective antibodies after the hepatitis B virus infection due to the good prognosis of the disease, or by the hepatitis B virus vaccination. However, in either case, it is basically normal, so the patient need not be overly worried about the test results. However, it is suggested that patients who have not received the hepatitis B vaccine, i.e. those who are negative for hepatitis B surface antibodies, still have a chance of being infected with the hepatitis B virus and it is recommended that they be vaccinated as soon as conditions permit. In particular, people with high-risk factors for hepatitis B infection, such as blood station workers and hemodialysis patients, are advised to follow the nationally prescribed immunization procedures to improve vaccination to avoid the risk of infection.
