finn: both blood 8:00am and 6:00 pm and 24 hour urine cortisol were high in my case ,if you do any testing I recomend the 24 hour urine cortisol , it is more accurate , as for saliva test I had 2 done about 3 months apart and both came back as very low cortisol ,I do not trust saliva test as they can be thrown off very easily by just drinking water before a test , blood and urine are more reliable in my case
also I do not recommend hydrocortisone or prednisone unless last resort as they can shut down your own bodies adrenal production for many months once discontinued and if the dose is high enogh even years in some cases (very nasty stuff)
