I was on 125mg of levo and recently had a blood test just for T4. The doctor gave me a phone blood test result that said i needed to reduce the levo by 25mg. He said to have a re-test in two months time. I have since asked for vitamin D & B and cortisol to be tested and for a copy of my blood test result as I have no idea of my levels. I also asked the doctor why he doesn't test me for T3 - he said they don't do this now. The doctor wants to see me to "discuss" the additional tests for vitamins and cortisol. Can anyone give me some tips on what i should be asking for/saying?
