Hi, I'm looking for some advice. My rheumatologist has requested that my GP carry out a Fasting cortisol test, anyone know what's involved and how to get the best results.
They have also suggested again that I have Chronic Fatigue and should be referred to a self-management program and a screen of sleep apnoea.
I am currently taking T3 and T4 medication.
Any advice about the cortisol tests would be very gratefully received.
