Hi, I have been given a trial of T3. My thyroxine has been reduced from 75mcg daily to 50 mcgs with T3 added at 5mcgs. I have been taking these for eight days so far. I have an appointment with a GP on Monday and will ask to have my blood tested for vitamins. My question is, which should I be asking for? I have Vit B12 injections. I self injected every other day for about eighteen months, and now around once a week. I also take a Vitamin B complex. I had my ferritin tested a few weeks ago privately and that came back quite high at 178 (13 to 150). I know I need to check Vit D and folate, for which I supplement, but wondered whether there is anything else I should ask for. These are my results from 16th May: TSH 1.4 mU/L 0.30 - 6.00
Free T4 21.0 pmol/L 10.4 - 24.5
Free T3 4.6 pmol/L 3.0 - 7.1
I would be grateful for any advice
Thank you
