Hormones
Cortisol
Extended panel — run periodically
What it indicates
An adrenal hormone that follows a daily rhythm, typically highest in the morning.
Why a series helps
Cortisol follows a daily rhythm, so a reading is only comparable with others taken at a similar time of day.
What this page does not tell you
What a particular Cortisol result means depends on you: your history, your medication, why the test was taken. Ziro does not interpret results for individuals and does not diagnose. If something in your results warrants a conversation, that conversation is with a doctor, and your results are downloadable so you can bring them.
