AND TPO( Antibodies)High levels of Thyroglobulin

Hi , High levels of antibodies indicate problems with the immune system, please help me to find the physician who is the best one to treat the condition, since there is no such specialty, who will treat it, what treatment will reduce the antibodies to normal levels ? Thanks for a good site- Nili
