[Assay of salivary cortisol. An interesting method for exploring the adrenal cortex].

AN INTERESTING METHOD FOR PATIENTS AND PHYSICIANS: Measurement of salivary cortisol has not modified the investigation of hospitalized patients but offers very original possibilities for exploring outpatients. REPEAT MEASUREMENTS AND STIMULATION TESTS: As for serum cortisol levels, repeat measurements or stimulation tests are required for reliable evaluation of salivary cortisol. SEVERAL APPLICATIONS: Salivary cortisol level can be an appropriate tool in screening for adrenal insufficiency, using the short ACTH injection test, evaluating hypercorticism through the circadian cycle of cortisol and overnight dexamethasone suppression test either at the physician's office or in the patient's home. In addition, long-term follow-up is possible for outpatients investigated or treated for Cushing's syndrome.
