Is it normal after taking the overnight dexamethasone suppression test to have your cortisol level be <0.8 mcg/dl, also did not fast.
Dex suppression test: 41 F from UT asks: Is it normal after taking overnight sex to have cortisol < 0.8 msg/dl and did not fast. ANS: To decide it it is normal I need to know a few more things. 1. What was the dose or Dex? 2. Why was it done? 3. What are the normal ranges for that lab? 4. What other meds were you taking? So can consult with me so i can get more details and answer better. But probably OK. ...Read more

Cortisol saliva test very high, but DEXA suppression test normal. have had fatigue, low BP, weakness for years. which test to believe, and what now?
Cushing's: There are several ways to screen for Cushings: 24 hr urine cortisol, overnight dex suppression, and midnight salivary cortisol. All would be altered if you took a steroid suppository. All need confirmation from other tests. Intermittant steroid use can cause symptoms of Cushing's, but no reason to think there is a tumor if you are taking steroids. You may need to see an Endocrinologist. ...Read more
Confused about dexamethasone suppression test. how can taking a steroid LOWER cortisol levels? having this to check for cushing's.
43 yro f tested high for cortisol in afternoon 28 ug/dl After suppression test am cortisol 3.7 and ACTH 2.0 CT showed adrenals normal. Ideas?
Cushing's diagnosis: Presumably you have symptoms (weight gain, skin changes, diabetes, etc). Sounds like you had screening tests (?overnight dex) but these tests do not establish the diagnosis. False positives occur with depression, obesity, alcohol consumption. You really need to see an Endocrinologist to get this worked up. If it is Cushing's, 70% is in the pituitary, not the adrenal. ...Read more
My a.M. Cortisol serum is routinely 35+ (range 9-21), but low dose suppression test was normal. Tsh is slightly high, T3 (liothyronine) is elevated too. Causes?
Oral contraceptive: The most likely explanation for these findings is being on an oral contraceptive (yaz). This raises the cortisol binding protein level, making the total cortisol level look high, but the biologically active cortisol is normal. The same thing happens for thyroid hormone, including T3 (liothyronine) levels. If you have hashimotos and your TSH is high, you have mild hypothyroidism. ...Read more
