A cortisol blood test measures the level of cortisol — a hormone made by the adrenal glands that helps control your stress response, blood pressure, blood sugar and metabolism.

Cortisol follows a daily rhythm, peaking in the morning and falling through the day, so the timing of the sample matters: it is usually taken around 9am. The test is used to investigate conditions where cortisol is too high (Cushing’s syndrome) or too low (Addison’s disease / adrenal insufficiency).

Understanding Your Cortisol Result

Because levels swing through the day, a single result is interpreted against the time it was taken. An unexpectedly high or low morning cortisol usually prompts further, more specific tests (such as a stimulation or suppression test) rather than being diagnostic on its own.

Stress, illness, pregnancy and some medications (including steroids and the contraceptive pill) can all affect the reading, so results are reviewed in context.

When Is a Cortisol Test Used?

It can help when investigating symptoms such as unexplained weight gain or loss, persistent fatigue, low blood pressure, muscle weakness, or changes in skin and mood that suggest an adrenal problem.

At The Vesey a morning cortisol test can be arranged with a GP who will interpret it and organise any specialist (endocrinology) follow-up needed.
