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.
A normal response to Dexamethasone is still suppression of Cortisol to less than 50 nmol/L. Synacthen tests: normal response is cortisol above 420 nmol/L on 30-minute sample. Consider pituitary failure if low baseline cortisol, especially if below 170 nmol/L in morning.
