Just a quick one
What should we aim for re optimal ferritin levels, mine is 24 ugl which was in a range of (10-204) this seems a rather large range to me.
Also, I had a cortisol test which was taken about 10.15 am and came out at 475, I can find info on how cortisol alters through the day, but nothing on healthy levels, and no range was provided with blood test result.
Thank you
