Re: I Had A Random Cortisol Test Done, Is 35 Normal Or High?
35 is high. Technically, there is not a refrence range for 10 am. They also vary a bit from lab to lab, but ******* uses a range of 4.3 - 22.4 ug/dL for 8 am. Esoterix uses a range of 8.0 - 19.0 ug/dL for a normal 8 am reading. The refrence ranges are 8 am, 4 pm, and midnight. In normal people, the 8 am has the highest reading of the day. This is what helps everyone get up and go. At 4 pm, it should be about half of the morning number. At midnight, it should be 0 or nearly 0.
Are you on steroids? If not, do you have signs of Cushing's? Have you had your cortisol drawn at other times of the day as well?
