A member asked:

I had two acth tests done two weeks apart. first one was low and second one is normal. cortisol is normal. what does this mean to me?

ACTH: The testing was done for a reason- that missing information is important to answer the question. ACTH goes up and down depending on stress and hormone levels. If you were under emotional stress or sick ACTH will change.
