An overnight dexamethasone suppression test should be performed in women with physical features of cortisol excess, such as hypertension, central obesity, facial plethora, easy bruising, striae, proximal muscle weakness and/or increased cervicodorsal-supra-clavicular fat. For this test, 1 mg of dexamethasone is administered orally at 11 ., and serum cortisol measurements are taken at 8 . the following morning. Serum cortisol levels below 5 μg per dL (140 nmol per L) make the diagnosis of Cushing's syndrome unlikely but are routinely present in women with polycystic ovary syndrome.
