Short ACTH stimulation test for adrenal reserves of cortisol, not adrenal function

We agree with the interpretation of the short ACTH stimulation test described by Deeba Syeda and associates. In the case that we described,¹ a long ACTH stimulation test was unnecessary because of the clinical picture, especially the hyperpigmentation and the markedly increased ACTH level (285 [normally less than 18] pmol/L).
