GENERAL INFORMATION

Testing Schedule

Mon - Fri

Expected TAT

Clinical Use

This test determines how the adrenal glands respond to a certain hormone. The hormone is called adrenocorticotrophic hormone, also known as ACTH. ACTH is made in the pituitary gland and travels through the bloodstream to the adrenal glands. ACTH stimulates the adrenal gland to release Cortisol. Cortisol is a key factor in many functions in the body's metabolism of fats, carbohydrates, sodium, potassium, and protein.
