A member asked:

Could a pituitary tumor cause delayed cortisol response on acth stim test?

A doctor has provided 1 answer

Definitely: If the tumor has destroyed the pituitary's ability to respond appropriately to hypothalamic cortisol releasing hormone, it can even lead to secondary adrenocortical insufficiency. Check w/your doctor.
