Cortisol Blood Test
The Cortisol blood test measures the level of cortisol in your bloodstream. Cortisol is a vital hormone produced by the adrenal glands and plays an essential role in regulating stress response, metabolism, blood pressure, immune function, and energy levels. Because cortisol affects many systems in the body, testing can provide valuable insight into your overall hormonal and adrenal health.

What is cortisol and why is it important?
Cortisol is often referred to as the body’s “stress hormone,” but its role extends far beyond stress alone. It helps regulate how your body uses carbohydrates, fats, and proteins, supports blood sugar balance, controls inflammation, and plays a key role in maintaining blood pressure. Cortisol levels naturally follow a daily rhythm, typically peaking in the morning and gradually decreasing throughout the day.
When cortisol production becomes too high or too low, it can affect how you feel physically and mentally. Imbalances may contribute to symptoms such as persistent fatigue, unexplained weight changes, low mood, sleep disturbances, or difficulty coping with stress.
Why might I need this test?
A cortisol test may be recommended if you are experiencing symptoms that suggest a hormonal or adrenal imbalance. These can include ongoing tiredness, muscle weakness, changes in appetite, dizziness, high or low blood pressure, or difficulty recovering from illness or stress.
Cortisol testing is also commonly used to help assess adrenal gland function and to support the investigation of conditions such as adrenal insufficiency or excess cortisol production. In some cases, it may be used to monitor known endocrine conditions or evaluate the effects of long-term steroid medication.
What do the results mean?
Cortisol results are interpreted based on the time of day the sample is taken, as levels fluctuate naturally. Higher-than-expected levels may be associated with prolonged stress, certain endocrine conditions, or medication effects. Lower levels may suggest reduced adrenal function or hormonal imbalance.
It is important to understand that cortisol results should never be viewed in isolation. A healthcare professional will consider your symptoms, medical history, and any additional test results before explaining what your result means and whether further investigation or follow-up is needed.
