Also known as: Cortisol AM

Cortisol, A.M.

A cortisol level is a blood test that measures the amount of cortisol, a steroid hormone produced by the adrenal gland. The test is done to check for increased or decreased cortisol production. Cortisol is a steroid hormone released from the adrenal gland in response to ACTH, a hormone from the pituitary gland in the brain. Cortisol affects many different body systems. It plays a role in: bone, circulatory system, immune system. metabolism of fats, carbohydrates, and protein. ervous system and stress responses.

When and Why the Cortisol Lab Test May Be Ordered

Timing of the Test: The Cortisol lab test is typically ordered in the morning to capture cortisol levels at their peak. It is performed for various reasons, depending on the clinical context and the patient's symptoms or health concerns.

Reasons for Ordering the Test:

  1. Assessment of Adrenal Function: Healthcare providers may order the Cortisol AM lab test to assess the functioning of the adrenal glands, which are responsible for producing cortisol. Abnormal cortisol levels may indicate adrenal dysfunction.

  2. Diagnosis and Management of Adrenal Disorders: Cortisol imbalances can be indicative of adrenal disorders such as Cushing's syndrome (excess cortisol production) or Addison's disease (insufficient cortisol production). The test results help diagnose and differentiate these conditions.

  3. Evaluation of Stress Response: Cortisol is often referred to as the "stress hormone" because its levels tend to rise in response to stress. The test can help evaluate how an individual's body responds to stressors.

  4. Circadian Rhythm Assessment: Cortisol follows a diurnal (daily) rhythm, with levels typically being highest in the morning and gradually decreasing throughout the day and night. This test assesses whether the cortisol rhythm is normal or disrupted.

  5. Investigation of Fatigue and Mood Disorders: Healthcare providers may order the Cortisol AM lab test if a patient presents with symptoms such as chronic fatigue, mood disturbances, unexplained weight changes, or abdominal pain. Cortisol imbalances can be associated with these symptoms.

What the Cortisol Lab Test Checks For

The Cortisol lab test measures cortisol levels in the morning. Cortisol is a steroid hormone produced by the adrenal glands that plays a crucial role in various physiological functions, including:

  • Regulating the body's response to stress.
  • Influencing metabolism, immune function, and blood pressure.
  • Supporting the body's sleep-wake cycle (circadian rhythm).
  • Contributing to the body's energy and glucose regulation.

How Health Care Providers Use the Results

Interpreting the results of the Cortisol lab test is essential for diagnosing and managing various health conditions:

  1. Assessment of Adrenal Function: Abnormal cortisol levels can indicate adrenal gland dysfunction, such as hyperactivity or hypoactivity. Healthcare providers use these results to assess adrenal health and guide further evaluation and treatment.

  2. Diagnosis and Management of Adrenal Disorders: Cortisol imbalances can be indicative of adrenal disorders. The test results help diagnose conditions like Cushing's syndrome or Addison's disease, allowing healthcare providers to develop appropriate treatment plans.

  3. Evaluation of Stress Response: Elevated cortisol levels may suggest a heightened stress response. This information can be valuable in understanding how an individual's body reacts to stressors and can aid in stress management strategies.

  4. Circadian Rhythm Assessment: The test results can indicate whether cortisol levels follow the normal diurnal pattern, helping healthcare providers identify disruptions in circadian rhythm, which can affect sleep and overall health.

  5. Investigation of Fatigue and Mood Disorders: Cortisol imbalances can contribute to symptoms like chronic fatigue, mood disturbances, and weight changes. Healthcare providers use the results to investigate potential underlying causes and develop appropriate treatment plans.

In summary, the Cortisol lab test assesses cortisol levels in the morning, providing valuable information about adrenal function, stress response, and potential underlying health issues. It aids in diagnosing adrenal disorders, evaluating stress-related symptoms, and guiding treatment strategies to improve a patient's overall well-being.

We advise having your results reviewed by a licensed medical healthcare professional for proper interpretation of your results.
