==Background==
*ACTH (cosyntropin) stimulation test measures how well the adrenal glands respond to adrenocorticotropic hormone (ACTH)
*ACTH is a hormone produced in the pituitary gland that stimulates the adrenal glands to release a hormone called cortisol
*Man-made form of ACTH is called cosyntropin

==Test==
#Before: Draw serum cortisol 
#Time 0: Give 0.25mg IM/IV of ACTH (Cosyntropin) over 2min (0.125mg if <2yrs old)
#Time 30: Draw serum cortisol 
#Time 60: Draw serum cortisol &amp; give 100mg hydrodortison IVP

*'''Normal Response:''' Cortisol level doubles from baseline after Cosyntropin administration 
*'''Adrenal Insufficiency:''' Cortisol level fails to rise after Cosyntropin administration

==Management==
*If abnormal test, can give:
**[[Dexamethasone]] 6mg IV '''OR''' [[Hydrocortisone]] 100mg IV
