ClinQuiz: LDDS - Answer 3E
3E-Incorrect. The cortisol concentration is 10 µg/dl at baseline, 4 µg/dl four hours after dexamethasone administration, and 10 µg/dl eight hours after dexamethasone administration, thus the dog exhibits at least 50% cortisol suppression at some point during the test, which is diagnostic for PDH.
