ACTH levels--distorted when on Cortef?

[Guest guest]

My recent lab showed ACTH as 8, cortisol 28. The doctor told me to take the 10mg

Cortef dose as usual prior to test, no other hormones. Does taking cortef

distord ACTH?

My original ACTH prior to any adrenal/thyroid hormones was 9 and also low, but

cortisol was 17.

A moderator on the hypotituitary board said the low ACTH with lot Ft4 and low

cortisol of 17 meant I would need good doses of Cortef for life.

Is this true, Val/Nick?

Another time the ACTH was at 42 and that was good, but I was extremly anxious

during the blood draw, so maybe that was why it was higher then?

So what about this still low ACTH? Does cortef distort it?
