I am wondering what ufc is.
Can you tell me more about your situation?
What tests did you have besides ufc?
Low dexamethasone or high dexamethasone? What are your symptoms?
ufc was measured twice?
Are you a male or a female? How tall are you? How much do you weigh? Any weight change? When did it start? Is it getting worse? Any other symptoms? Are you aware of anything which might have triggered it? Any medical problems? Any surgeries? Any medications including over-the-counter pills and herbs? Any family medical history?
Did you have inferior petrosal sinus sampling?
The diagnosis of CS is established when at least two different first-line tests are unequivocally abnormal. The first-line tests are late-night salivary cortisol (two measurements), 24-hour urinary free cortisol (UFC) excretion (two measurements), or the overnight 1 mg dexamethasone suppression test (DST). You have abnormal results in UFC and DST. You have CS. And since high dose DST suppressed cortisol and MRI is negative, you should have IPSS.
It is diagnosis criteria. You have CS. You need to have IPSS.
