The corticotropin stimulation test uses the standard 250-mcg intravenous injection. In aldosteronomas, a robust aldosterone response is typically observed. In idiopathic adrenal hyperplasia (IAH), the aldosterone surge is considerably more feeble. The test is no longer used, because the discriminant value of the test is rather poor. [6]
