Guest guest Posted December 18, 2008 Report Share Posted December 18, 2008 A question about pituitary function: if my TSH output seems to fluctuate properly with T4 supplementation (more T4 = less TSH), can I assume that the pituitary's adrenal feedback loop will also be functioning properly? Has anyone had a bad ACTH Stim test, but has good thyroid feedback? Marla Quote Link to comment Share on other sites More sharing options...

No, it is a matter of magnitude of the response in addition to direction. Chuck Quote Link to comment Share on other sites More sharing options...
