Yeah. According to the normal cortisol curve, serum cortisol should be around 20-25% lower at 10.30 AM in comparison to 8.00 AM.Yes, but I didn't manage to do it at 8 am like it says on the panel, it was around 10:30.
Reference range for plasma (according to my results paper) is 101,2 - 535,7 nmol/l at 8 am.
If cortisol peaks at 8 am and then slowly decreases from there throughout the day, that means at 8 am my value was probably around 500, right?
So an estimated calculation could be:
454 nmol/L x 1,2 (for 20%) = 544 nmol/L (roughly at 8:00 am)
So definitely on the high side. Ray said serum cortisol should not be higher than the middle of the reference range. (so ~300 nmol/L)
