The purpose of this study is to determine the cortisol levels that most accurately diagnose a patient with adrenal insufficiency, a condition in which cortisol levels are too low for daily living.
In this study, a cosyntropin (ACTH) stimulation test will be conducted by administering intramuscular cosyntropin into a subject's arm and measuring cortisol levels before and after injection. Cosyntropin tests are routine medical tests that are done in doctors' offices to diagnose adrenal insufficiency. Cosyntropin is a synthetic version of a hormone, called ACTH, that is secreted by our bodies to help produce cortisol. Participation in this research will last about two hours. Aim # 1: The primary aim is to accurately re-define the cortisol threshold to diagnose adrenal insufficiency with c…
Inclusion Criteria for healthy volunteers: \- Male and female outpatients 18 years or older without prior diagnosis of primary or central adrenal insufficiency Inclusion Criteria for patients with known adrenal insufficiency: \- Males and females 18 years or older with established diagnosis of primary or central adrenal insufficiency as previously documented in the electronic medical record by a failed CST (peak cortisol level \< 18 μg/dL) or morning serum cortisol \< 3 mcg/dL with an appropriate clinical circumstance (e.g., Sheehan's syndrome, pituitary surgery and/or irradiation, bilatera…
