There are five values for hepatitis B. For example, a simple positive surface antigen often indicates that the patient has a possible hepatitis B infection. If there is a positive surface antibody in there, this is often a good thing, indicating that he or she is producing protective antibodies against hepatitis B and does not have hepatitis B infection. In addition to surface antigen and surface antibodies, most people have positive core antibodies. A single positive core antibody is influenced by two factors: having been infected with hepatitis B and being in recovery; and false positives, in the method of detecting core antibodies, immunocoupling reactions some antibodies are non-specific. Less than 5% of the population is occult hepatitis B, where the surface antigen is negative and the surface or core antibodies are positive, when the patient has liver insufficiency and a DNA check for hepatitis B will reveal a positive result. So there are a few people with occult hepatitis B who show a single positive antibody on the hepatitis B triplet system, but the population is small.
