Hepatitis B positives and negatives usually refer to positives and negatives for the hepatitis B surface antigen. The difference between hepatitis B surface antigen positive and negative is whether or not you are infected with the hepatitis B virus. Hepatitis B surface antigen is positive usually indicates the presence of hepatitis B virus in the patient’s body, i.e., the patient is infected with hepatitis B virus, and it is recommended that further examination of hepatitis B penta-analysis, quantification of hepatitis B virus DNA, and liver function is needed to clarify the condition of hepatitis B. When the hepatitis B surface antigen is negative, it means that the patient is not infected with hepatitis B virus and is not a carrier of hepatitis B virus. The Hepatitis B test usually includes the results of Hepatitis B surface antigen, Hepatitis B surface antibody, Hepatitis B E antigen, Hepatitis B E antibody, and Hepatitis B core antibody. If Hepatitis B surface antibody is positive, it means that there are protective antibodies against Hepatitis B virus in the body, and the body has the ability to fight against Hepatitis B virus and has a certain degree of immunity.
