Late-Night Salivary Cortisol. Late-night salivary cortisol is one of the most sensitive diagnostic tests for Cushingâs syndrome. Elevated cortisol between 11:00 p.m. and midnight appears to be the earliest detectable abnormality in many patients with this disorder.hree diagnostic studies are currently recommended: late-night salivary cortisol, 24 hour urine free cortisol, low-dose dexamethasone suppression. If any of these tests is abnormal, a referral to an endocrinologist is strongly encouraged.
Multiple blood and/or saliva cortisol levels collected at different times, such as at 8 am and 4 pm, can be used to evaluate both cortisol levels and diurnal variation. A 24-hour urine cortisol sample will not show diurnal variation; it will measure the total amount of unbound cortisol excreted in 24 hours.
