Cortisol is a steroid hormone produced by the adrenal glands in response to stress. It plays a crucial role in regulating metabolism, immune function, and the body's stress response. The test measures the level of cortisol in the blood to evaluate adrenal gland function and diagnose conditions such as Cushing's syndrome or Addison's disease. Cortisol levels typically follow a diurnal rhythm, with highest levels in the morning and lowest at night. Abnormal cortisol levels can indicate various endocrine disorders, chronic stress, or problems with the pituitary gland.

What do readings below 6.2 mcg/dL for Cortisol - CORT mean?

A low cortisol reading may indicate:

  1. Adrenal insufficiency (Addison’s disease)
  2. Hypopituitarism
  3. Congenital adrenal hyperplasia
  4. Secondary adrenal insufficiency
  5. Suppression due to long-term glucocorticoid therapy

Low cortisol can lead to fatigue, weakness, weight loss, low blood pressure, and increased susceptibility to stress and infections. Further testing may be necessary to determine the underlying cause and appropriate treatment.

What do readings above 19.8 mcg/dL for Cortisol - CORT mean?

A high cortisol reading may indicate:

  1. Cushing’s syndrome
  2. Severe stress or illness
  3. Pituitary tumor (Cushing’s disease)
  4. Adrenal tumor
  5. Excessive ACTH production
  6. Certain medications (e.g., oral contraceptives)

High cortisol can result in weight gain, particularly around the midsection, muscle weakness, easy bruising, mood changes, and metabolic disturbances. Additional tests may be required to identify the cause and determine appropriate management.
