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.
In a normal dog, the dexamethasone should suppress cortisol levels in the blood stream. In Cushing's disease this effect does not occur. Once the disease is diagnosed, it is possible to differentiate between the adrenal tumors and pituitary gland tumors using a second test, a high dose dexamethasone suppression test. Most dogs with pituitary tumors will have cortisol suppression on this test.
