what is an acth stimulation test
The ACTH stimulation test is recognized as the gold standard assay of adrenal insufficiency, although this test is primarily used to determine the presence of Addison's disease and pituitary impairment.his test measures how much ACTH the pituitary gland is producing. A healthy ACTH value should be just into the upper third of the range (assuming a range of 10â60 ng/L). The ACTH plasma and ACTH stimulation test together can give a clearer picture, especially for secondary adrenal insufficiency.
