Hepatitis B negative generally refers to a negative test result for both half pairs of hepatitis B, which indicates the absence of antibodies. Generally speaking, hepatitis B negative refers to a negative result of both half pairs of hepatitis B tests, which indicates that an individual is not infected with or carrying the hepatitis B virus. For the presence of antibodies against hepatitis B virus in the human body, the main reference is the presence of hepatitis B surface antibodies, which indicate that the human body has produced antibodies against hepatitis B, which is the body’s immune and protective antibodies against the hepatitis B virus. This antibody may be acquired due to immunization by independent vaccination, or a certain degree of immunity after previous infection. If the result of the test is negative, it means that the individual does not have immunity against the hepatitis B virus. In addition, positive hepatitis B surface antibody only means that the body has produced antibodies, and if you want to judge whether the individual has sufficient immunity against hepatitis B, or whether it is necessary to be vaccinated or supplemented with the hepatitis B vaccine, you need to quantitatively test the test, and the physician will decide based on the test results.
