Cortisol Test
The Cortisol Test measures cortisol levels in the blood, a hormone key to stress response, metabolism, and immune regulation.
The Cortisol Test measures the levels of cortisol, a hormone produced by the adrenal glands, in the blood. Cortisol is involved in various bodily functions, including stress response, metabolism, and immune system regulation.

A little more detail:
A cortisol test measures the level of cortisol, a hormone produced by the adrenal glands, which plays a crucial role in regulating metabolism, immune response, and the body’s reaction to stress. Cortisol levels naturally fluctuate throughout the day, typically highest in the morning and lowest at night. This hormone is often referred to as the “stress hormone” because it helps the body respond to stress by increasing blood sugar levels and enhancing the brain’s use of glucose.
Cortisol testing is used to diagnose conditions related to cortisol imbalances, such as Cushing’s syndrome (caused by excess cortisol) or Addison’s disease (caused by insufficient cortisol). Symptoms of high cortisol may include weight gain, high blood pressure, and mood changes, while low cortisol levels may result in fatigue, low blood pressure, and muscle weakness.
The test can be conducted through blood, urine, or saliva samples. Blood tests are commonly done in the morning, while urine tests may require a 24-hour collection to measure cortisol levels over an entire day. Saliva tests are often used to assess nighttime cortisol levels.
Understanding cortisol levels helps doctors assess adrenal gland function and diagnose disorders that affect hormone regulation, guiding further diagnostic testing and treatment.
