Query 24 hour variation of TSH

[cjrsquared]

I believe I have previously seen information or a link that showed the 24 hour variation possible of either TSH or ft3. I would be grateful if anyone can point me in the right direction to find this info. Many thanks.

Me too - am wondering if I re-posted it but search is so bad, I couldn' find it.

TSH becomes irrelevent when at low levels.

I know that TSH is irrelevant at low levels and mine is kept suppressed due to thyroid ca. I am putting together some of the research that has been shared into a folder for my own information. I find the physiology and the biochemistry very interesting and you never know when you may need to produce some research when debating with some health professionals.
