Six weeks ago TSH 77 T4 12 on Thyroxine 225mcgs, at gp for thyroid blood check this morning, doctors just called me at home as TSH now 0.2 & T4 26 he doesn't understand what is happening he's trying to get hold of endocrinologist for advice but probably not going to happen at 1700 on a Friday. Thinks there has to be something else going on for TSH to drop so quickly from 77 to 0.2 & also for T4 to rise from 12 to 26. Advised cut Thyroxine from 225mcgs to 200mcgs & will repeat blood check in 8weeks. Surprised I'm still off work but I just feel awful. I would appreciate any advice as to what these readings mean?
