Hormones
26Cortisol
We advise against measuring cortisol if your question is about stress, burnout, fatigue or weight gain. Cortisol fluctuates so much that your value has to roughly double before any change is detectable, and the contraceptive pill, pregnancy, night shifts and even the stress of the blood draw itself shift the result. If your doctor requested this measurement, have your blood drawn between 06:00 and 10:00 in the morning. Read why we advise against this test.
