Very high ft4 - 150

when they diagnosed me with hyperthyroidism I had this result 151,88 (10,04 - 28,18)

does anyone knows how long it takes to the ft4 to get so high? I had tachycardia for at least one and a half year before this diagnosis but nobody thought to test my thyroid until I changed my gp...

looking at the pictures at that time I realized that it is clear enough that the thyroid was bigger than normal

That's a difficult question to answer, it would probably be different, for different people and different causes.

What medication and dose are you on now? And are you feeling better?


I was on Tiamazol 30 mg/day and Propranolol. Then RAI. Now im hypo and feeling worse


Has anyone seen/heard such a result?
