The ACTH test (also called the cosyntropin, tetracosactide, or Synacthen test) is a medical test usually requested and interpreted by endocrinologists to assess the functioning of the adrenal glands' stress response by measuring the adrenal response to adrenocorticotropic hormone (ACTH; corticotropin) or another corticotropic agent such as tetracosactide (cosyntropin, tetracosactrin; Synacthen ...
A cosyntropin stimulation test may be needed in mild cases, but usually, the random levels of 17OHP are high enough to confirm the diagnosis. [ 92 ] [ 93 ] [ 94 ] Elevated 17OHP may activate the androgen "backdoor" pathway, that leads to an excess of 5α-dihydrotestosterone and other potent androgens.
Adrenocorticotropic hormone is used as a medication and as diagnostic agent in the ACTH stimulation test. [ 1 ] [ 2 ] : 316, 1165 [ 3 ] : 84, 271 The form that is purified from pig pituitary glands is known as corticotropin [ 1 ] [ 2 ] : 316 is a medication and naturally occurring polypeptide tropic hormone produced and secreted by the anterior ...

Evocative/suppression testing refers to a class of tests performed where one substance is measured both before and after the administration of another substance to determine if the levels are stimulated ("evocative") or suppressed.
Metyrapone can be used in the diagnosis of adrenal insufficiency.Metyrapone 30 mg/kg, maximum dose 3,000 mg, is administered at midnight usually with a snack. The plasma cortisol and 11-deoxycortisol are measured the next morning between 8:00 and 9:00 am.
A combined rapid anterior pituitary evaluation panel or triple bolus test or a dynamic pituitary function test is a medical diagnostic procedure used to assess a patient's pituitary function. A triple bolus test is usually ordered and interpreted by endocrinologists. [citation needed] In rare cases, it has been associated with pituitary ...
The corticorelin stimulation test helps to differentiate between the causes for adrenocorticotropic hormone (ACTH)-dependent hypercortisolism.It is used to distinguish a pituitary source of excessive ACTH secretion from a different source.
