Can you have hypothyroidism and have negative antibodies? I just writing a short letter to the GP that is visiting me on Thursday along with the private results that the other GP (horrible one lol) hasn't put onto the GP system. He said I could not have hypothyroidism as my antibodies were normal. My TSH is high. So my question is, is he right? I don't want to look a fool challenging this with the nice GP that's coming to see me on Thursday.
