last yaer about this time I had my saliva cortisol test done and it came back as very low ,but two months later my doc at the time had me do a 24 hour urine cortisol and a blood cortisol at the same time they both came back as very high almost cushing syndrome territory , which explains why when my doc put me on hydocortisone I felt very bad and had to stop taking it , I still don't understand why the test came back so different , then I repeated the tests again and they came back with the previous results ?
