During ACTH stimulation testing, which hormone is measured to assess adrenal function?

Explanation:
ACTH stimulation testing assesses how well the adrenal glands respond to ACTH by producing cortisol. After giving ACTH, the crucial measurement is cortisol, because cortisol is the glucocorticoid output of the adrenal cortex in response to ACTH. By checking cortisol levels before and after stimulation, you can tell if the adrenal glands are functioning properly. Insulin and glucose relate to energy metabolism, not adrenal response, and thyroxine reflects thyroid function, not adrenal function.
