| Additional information | For Depressive Illness based on Carrollet al. Arch Gen Psych 1981;38:15. 1 mg dexamethasone is given at 2300 on day 1, and serum cortisol levels are obtained 18 and 24 hours later (1600 and 2300 on day 2). A cortisol level of > 4 µg/dL (> 110 nmol/L) in either day 2 specimen is considered abnormal. Indomethacin and similar drugs may give false-negative results, and the diagnostic value of this test is in any case dubious. |
