I wonder if I ought to request to have my potassium and sodium tested again. Right now the lab requisition is for TSH, Free T4, Free T3, ferretin, vitamin B12, and CBC.
I wonder if it is possible to improve thyroid function if the adrenals are properly supported since both are part of the same system (endocrine).

Thanks for your reply. What was the measurement and reference range for your cortisol test result? I highly doubt my GP would order an ultrasound given he seems unconcerned about my adrenals even though they are part of the endocrine system along with my thyroid ... I will have to look up what a ACTH stim test is.
Thanks for your reply. I am unfamiliar with all of those tests you mention.
How do I get this testing if my GP doesn't believe I have an adrenal issue based on one AM cortisol test 487 reference range 170 – 540 nmol/L. This was the result after a 1/2 hour walk to the lab. He knows I have hypothyroidism, but he seems to have no interest in whether it is primary or secondary.

Sodium 141 Reference range 135 – 145 mmol/L
Potassium 4.2 Reference range 3.3 – 5.1 mmol/L
Do you have abnormal sodium and potassium readings - or low/high end readings? That is indicative of a low adrenal issue. If normal, it may be normal.
As it is, you need many tests (acth, renin, aldosterone etc) and I would suggest not only the free type but also serum to get a baseline on if you have an adrenal issue. Then a stim test to finalize it.
