What is Cortisol?
Cortisol is a hormone produced by the adrenal glands that helps regulate metabolism, the stress response and other functions. Its level naturally follows a daily rhythm, typically higher in the morning.
Why it's testedWhy check your Cortisol?
Cortisol is measured when assessing the body’s stress-hormone axis, usually with attention to the time of sampling. It features in stress-oriented and endocrine panels.
Panels that include Cortisol
Cortisol is a standalone test, but it's often more useful — and better value — checked alongside related markers. These panels include it:
Stress Panel

Fertility Panel
This panel screens 9 markers across the systems that influence fertility, rather than hormones alone.
