Finally got my GP to test for T3 which took a lot of asking! The result was 5.7 but I have no idea what this means. I have no idea is this is 'free' T3 as no one at the surgery was able to tell me.My T4 has varied between 22 and 32.5 but the last result was 18 which I understand is normal. This was taken at the same time as the T3. My TSH is still 0.01. I don't know what these results mean but I'm still having the same symptoms of weight gain, feeling cold etc. I would really appreciate any advice on how to interpret these results.
