What is a dexamethasone suppression test ? A dexamethasone suppression test can help a doctor learn the cause of a patient having high levels of the hormone cortisol. The doctor gives the patient dexamethasone, a synthetic version of cortisol, and checks the patient's urine to see how his or her body responds.
Overnight suppression test: Serum cortisol is checked at baseline, then dexamethasone (typically 8 mg) is given orally between 11 pm and midnight. Cortisol level is then checked between 8 am and 9 am the next morning.he 24-hour urine free cortisol test may be used during the second day of the standard test as an end point; however, data suggest that serum cortisol has higher diagnostic accuracy and conducting both tests is not recommended.
