CORTISOL SERUM (EVENING SAMPLE 4pm -8pm)

This test measures the level of cortisol, a hormone produced by the adrenal glands which helps regulate stress, blood pressure, blood sugar and metabolism. Cortisol levels naturally drop throughout the day, so testing in the evening helps doctors assess whether your body’s daily cortisol rhythm is normal. It is useful in diagnosing adrenal gland disorders, such as Cushing’s syndrome or Addison’s disease.
