First time on site. Have had an under active thyroid for many years and although I'm on 125mg of levothyroxine per day I never feel well. I'm overweight although I'm continually on a diet, I'm always tired and I'm prone to infections. Recently I asked for a print out of my results (which I've never had before) and was told that I was normal. I just want to check if this is so. Here are my results:
Serum free T4 Level 17.5 pmol/L (12-22)
Serum TSH Level 2.14 mU/L (0.27-4.2)
Serum free T3 Level 4.1 pmol/L (3.1-6,8)
Could someone please explain these to me.
