Cortisol changes through the day
It is usually highest in the morning and lowest around midnight. That is why the time of your blood draw matters, and why one number can’t tell the whole story.

How we choose what to recommend
We point you to the smallest test that answers your question, and we say plainly what it can’t tell you. Medical claims link to their sources. A cortisol blood test can’t diagnose or rule out an adrenal condition by itself, so serious symptoms belong with a clinician.
