Continue to take: You are a hepatitis B virus carrier. With the use of the antiviral agent, tenofovir, you have successfully suppressed viral replication, which will help reduce the risk of hepatitis progression. This does not mean that you are cured however, and you will need to take this medication, as prescribed, otherwise you are at risk for viral reactivation and developing a drug resistant mutation. ...Read more
Hep B: Hep B core IgM antibody is only present in acute infection. The IgM will then be lost, and you develop Heb B core antibody total (IgG) that persists for life. After acute infection, one hopefully loses the surface antigen and develops surface antibody, which indicates lifelong immunity. The surface antibody also persists for life. If persisting surface antigen, this indicates chronic infection. ...Read more
