After testing “ reactive “ to the HBsAg test ( Hep B surface antigen ) For a little over year .... I recently tested “non-reactive” twice in the last five weeks . I also tested a value 10 iu /L ( not ) to the HBsAb test . I understand the CDC considers a 10 IU/L HBsAb immunity .... should I have good reason to believe that I have cleared the Hep B virus ?
