Factors that interfere with this test are:

• Medications, including glucocorticoids, lithium, diuretics, ketoconazole, estrogens and tricyclic antidepressants
• Severe emotional or physical stress

Note: Due to these interfering factors, the urine cortisol is often tested on three or more separate occasions to get a more accurate picture of average cortisol production.
