- ACTH (Cosyntropin) Stimulation Test: What It Is Results
What is an ACTH stimulation test? An ACTH stimulation test, also known as a cosyntropin stimulation test (CST), is a dynamic medical test that assesses how well your adrenal glands respond to adrenocorticotropic hormone (ACTH) This test is the main medical test to diagnose adrenal insufficiency — either primary, secondary or tertiary adrenal insufficiency
- ACTH - Overview: Adrenocorticotropic Hormone, Plasma
Corticotropin (previously adrenocorticotropic hormone: ACTH) is synthesized by the pituitary in response to corticotropin-releasing hormone (CRH), which is released by the hypothalamus ACTH stimulates adrenal cortisol production Plasma ACTH and cortisol levels exhibit peaks (6-8 a m ) and nadir (11 p m )

ACTH Stimulation Test (Cosyntropin) Purpose: Evaluation of possible primary or secondary adrenal insufficiency, as well as disorders of adrenal steroid biosynthesis, such as congenital adrenal hyperplasia (CAH) 1,2 Rationale: Cosyntropin, (ACTH 1-24), consists of the first 24 amino acids of the N-terminal portion of the intact native ACTH molecule (ACTH 1-36)

A higher-than-normal level of ACTH may indicate: Adrenal glands not producing enough cortisol (Addison disease)Adrenal glands not producing enough hormones (congenital adrenal hyperplasia)One or more of the endocrine glands are overactive or have formed a tumor (multiple endocrine neoplasia type I)Pituitary is making too much ACTH (Cushing disease), which is usually caused by a non-cancerous

The adrenocorticotropin hormone (ACTH) is synthesized by the corticotroph cells of the anterior pituitary gland ACTH, a post-translational product of the proopiomelanocortin protein (POMC), is a 39-amino acid peptide, its sequence being highly conserved in mammals ACTH binds to the highly specific, for ACTH, melanocortin (MC) 2 receptors (MC2R) located on the surface of adrenal zona
