Negative hepatitis B surface antigen is a good sign. Hepatitis B surface antigen is the outer shell of the Hepatitis B virus and being negative is not contagious. Hepatitis B surface antigen negative is a good sign. When testing for Hepatitis B 5, finding a positive Hepatitis B surface antigen suggests that there may be a Hepatitis B virus infection, suggesting that the patient is harboring the Hepatitis B virus, and in this case it is also necessary to monitor the number of Hepatitis B virus replications to determine whether or not it is necessary to start antiviral treatment. If the patient is positive for Hepatitis B surface antigen, Hepatitis B e antigen, and Hepatitis B core antibody, he/she has Hepatitis B triple positive. Hepatitis B surface antigen positivity, hepatitis B e antibody positivity, and core antibody positivity are indicative of hepatitis B minor triple positive. All need to be evaluated for the amount of hepatitis B virus replication to determine how infectious it is. Clinical findings of hepatitis B surface antigen positivity or abnormal hepatitis B 5 test results should be seen in the infection department of a regular hospital.
