I went to get my latest blood results today (started Levo in Aug) and saw a different GP. From 4.15 last month my TSH is now 1.1 (T4 not even tested!) so my usual GP wrote on my notes "Normal-no action necessary). I queried this with the new GP and said I didn't feel any different. And you know what? She listened to me!! She asked what my symptoms are and to cut a long story short I had to give 5 samples of blood and she is testing for loads of things: Prolactin, Coeliac, Vit D, B12, and others I'd never even heard of. Plus T3 which my previous GP said my area health authority wouldn't test for! I am so impressed and feel I may get somewhere at last I am definitely putting the lottery on tonight!!
