Well, the ACTH test is just written as 'ACTH', not 'ACTH response', nor outlined with a time table the way the glucose response test. Nor did he go into detail about the ACTH test the way he did with the glucose response test. He made it very clear that the GRT was one I would have to sit there for, but he did not say that about the ACTH. I believe the ACTH is just a snapshot (again), but I called and left a message for a callback to confirm.

And yes, I will definitely be calling back to see if I can get on a cancel list.
