My wife had RAI 6 months ago after several attempts to battle Graves with drugs. Although FT3 and 4 are now in normal range on a moderate dose of thyroxine, her TSH is 22 (range 0.4 - 4.00)
What we we don't understand is that the docter only focuses on ft3 and 4 and says all is fine.
I cannot find anything definitive online or research that suggest what the target TSH should be after RAI, or even if it is any longer important as there is no longer much (any?) thyroid left to interact with.
Can anyone point me in the direction of some good info on this subject. Manmy thanks

A high TSH indicates hypothyroidism or undermedication, while a low TSH can mean several different things. I wrote a book about Graves' patients' (and all thyroid patients') problems with dosing by TSH. Link should be at the top of this page.
