Hi there just wondering if anyone had a blood test called 'immunoglobulins' testing for igg, iga & igm when looking for possible auto immune issues? I had it done along with a few other tests and my iGA levels are slightly raised. Not too much though, the higher part of the normal range was 3.5 and my level was 4.3. Does anyone know much about this and could it be a potential immune issue? I.e. my immune system is too 'strong'? What do u think? Has anyone else had this test?
