Yes here doctor will not run additional thyroid panels.
Your doctor was having you do a dexamethasone suppression test and that is usually testing for high cortisol, not low.
The range does not apply for the suppression test.

Non-suppression is considered to be above 3.5

Another factor is if the ACTH was handled correctly - was the tube an EDTA (lavender), chilled is best, and instead of being put into the bin, the tech put from the techs hot hand into the centrafuge where it can be frozen promptly as ACTH degrades really fast at room temp. So your low reading can have that as a factor as well - as that seems, well, too low. Doctors tend not to pick up on this. Why, no idea.
That was it for thyroid tests?
Yes - it does look that way.
Check out Dr Wilson's adrenal fatigue web site - you may find some very helpful tips to get that healed up.
I thought thyroid repair was slow - never did I think this adrenal stuff was even slower to fix than thyroid.
That doctor Wilson's information is a must read
