I wonder if any can advise me. I go for bloods every three months at my GP. I am on 175mcg of combined thyroxine. I also take a high does vitamins as I find the b12 complex has stopped the occasional heart flutters I was getting. Anyway, the surgery no longer gives me a full thyroid screen (ie t3, t4, free t3 etc). They only take tsh and have said that if there are concerns with this then they test the other related aspects but not before. I struggle to understand how tsh can give me a good idea of what's going on when I don't actually have a thyroid any longer as had it removed 4 years ago. They used to give me a full screen and blood chemistry every three months and now I feel I am part of NHL cut balls to try and save money. Please advise and what can I do?
