Hi all, just seen my new doctor and asked about why have i been given three diagnosis for hypothyroid primary, autoimmune hypothyroid and graves. Still not sure but he said maybe the hospital tested for antibodies and it wasn't on the GPs system. Anyway he managed to find my TPO result which was tested in 2015 and said it was in range although there wasn't any ranges for him to give me. The TPO was 314. Not sure what this means or where in the range that falls. He said they can diagnosis autoimmune hypothyroid without the anti tests but that goes against what ive read and learnt from you guys. I have the other codes for antibodies and printouts from all the bloods the hospital has done but they have never tested for them , hence why the endo thought i had graves. Now im wondering has my high dose of levothyroxine caused symptoms relating to graves for the endo to think i may have graves. My endo also wrote a letter to my GPs confirming this. Any ideas what next. I see my endo on the 24th of this month so need advise.
