What is ACTH?
This assay is used to determine the cause of Hypocortisolism & Hypercortisolism
states. In a patient with hypocortisolism, an elevated ACTH indicates Primary
adrenal insufficiency whereas normal levels are consistent with secondary adranal
insufficiency from pituitary or hypothalamic causes. In a patient of hypercortisolism
(Cushing's syndrome), a suppressed value is consistent with Cortisol producing
Adrenal adenoma/carcinoma, Primary adrenal micronodular hyperplasia &
Exogenous corticosteroid use.
