As far as testing goes, to me it sounds like a good idea. When this forum started people all were just experimenting and did not think of doing the test, though we knew it existed.
Some day I might still like to do the test, since I have done the Lugol's for 7 months and I decided that may be the time had come to cut back back to maintenance of a couple of drops a day.
By intuition I might do this for awhile and before I go up again have the test done.
I still see my MD and he was fine with what I was doing but thought may be I should slow down since my TSH had gone up from 1 to 4, what was still ok.
