This is a remarkable paper and has big implications for testing and the diagnostic algorithm, especially given who the authors are. The blunt takeaway is do not use salivary cortisol for adrenal Cushing's because it doesn't work. They recommend dex test instead but we know that test has problems too--yes, even in adrenal cases. It's not clear to me if this is generalizable to all mild Cushing's, nor does it appear like cyclical or episodic Cushing's was considered. The other thing is that the technically "better" assay (LCMS) has worse sensitivity than the older, cheaper one (EIA). This is the

Wow 8.4 on the first try. These are textbook adrenal numbers. I hope your doctors come to their senses.

Hi Amanda, Based on what you posted, this is a slam dunk. If they don't diagnose you quickly you should go elsewhere. The lit recommends removing anything over 4 cm. You actually have convincing biochemical evidence with a rather high UFC and concurrent low ACTH (<10 pg/mL). I'm assuming you're using Quest for the UFC since he said it's not 2x high. Most people don't get to 2x on LC/MS-MS with mild/adrenal Cushing's. Let us know the dex results. The cutoff is 1.8 ug/dL.

Yes, that is common.

This would be a huge loss if the boards close. Surely there's a way to do site backup / archiving. I think the information here is much too valuable to lose forever.
