In patients with low (&amp;lt;\u200510 pg\/mL) or indeterminate (10-20 pg\/mL) basalACTH levels, an absent or reduced peakACTH response was able to differentiate adrenal from ACTH-dependent forms. PeakACTH and peakcortisol after hCRHtest were lower in pseudo-CS than in CD, but \u2206%ACTH and \u2206%cortisol were similar.
