A member asked:

I had cortisol blood test at 8:20 in the morning my level is 19.9 what it means is it considered high. thank you?

Don't know: why you would have had a morning cortisol done, but your value is normal. If you're concerned about cortisol excess, the afternoon (4pm) value or a suppression test may help. Talk w/your doctor.
