I got some tests done. My MRI, nerves and adrenal are normal. I did cortisol test after tablet Dexamethasone 1 mg. The value went from 34 mg/dL in the morning to 3.4 mg/dL and ACTH from 63.4 pg/mL to 5.7 pg/mL. Other values are FT4 1.98 ng/dL, GH 4.4 ng/mL, SM-C 104 ng/mL, anti-TPO 9 IU/mL, anti-TG 40 mIU/mL and creatinine 0.60 mg/dL. GnRH and TRH are yet to be done. From the results, what is your opinion about my condition? Is it Cushing's syndrome? Should I take Signifor or Metyrapone?
