hi doctorMy GammaGT is high from so many years.  it is 74 where it has to be less than 49 from year 2004 onwards.  I took Twin-Rix vancinne in year 2005.  I did my blood test in Nov 2007 where surface Antibodies (HBsAb) is greater than 1000.  What does than mean.  Am I infected with Hep B
No you are not infected with Hepatitis-B virusHepatits-B vaccine contain some part of virus which when injected into body produces antibody and because of this antibody formation, body is protected against Hepatitis-B virus infection in the future. Anytime after vaccination, elevated level of Anti-bug antibody indicates adequate response due to vaccinationHepatits-B infectivity in such cases can not be interpreted based on Anti-HbsAb antibody only. It requires result of Bag antigen, Anti-HbcAb antibody also
