What is the Cortisol Test?
A cortisol test may help diagnose Cushing syndrome and Addison disease. The test looks for pituitary and adrenal gland disorders. It does so by monitoring the stress hormone cortisol in your blood.
The adrenal glands create cortisol which is a steroid hormone that helps in stress response, blood sugar regulation, and infection resistance. In the morning, cortisol levels are typically highest, and at night they are lowest. When you’re nervous or stressed, your body produces too much cortisol, which can harm your health if it stays too high for too long, and a high or low cortisol level may indicate a medical condition.
What is the Cortisol Test used for?
The cortisol level test determines if cortisol production is too high or excessively low. Addison’s and Cushing’s illness affects the quantity of cortisol produced by your adrenal glands, and this test identifies many disorders and analyses the adrenal and pituitary glands’ function, including:
- Stress responses
- Immune system
- Nervous system
- Circulatory system
- Skeletal system
- Protein, fat, and carbohydrate breakdown
Understanding the test results of the Cortisol Test
Cortisol levels too high or too low may indicate Cushing’s syndrome or another adrenal condition. If your cortisol levels are abnormal, this does not always indicate that you have a medical condition that requires treatment. Additional factors like infection, stress, and pregnancy may influence your results. Contraceptives and other medications might potentially affect your cortisol levels.
