Normal curve starts higher upon waking then decreases throughout the day. The order displayed looks correct for a daily test starting at 8am.
My own numbers were incredibly close to yours with the exception of 4pm:
8am .226, range 0.025 - 0.600
12noon .061, range 0.010 - 0.330
4pm .044, range 0.010 - 0.200
10:00 .010, range <0.010 - 0.090
Dr Saya said the curve is good but the overall level is low. I am starting Thyroid (NDT), and we'll see if it bumps cortisol a bit. To be continued...
