Description
Cortisol (am)
Sample Type: Serum
Sample Required:
Blood sample (usually collected in the morning)
Test Time:
Results typically available within a few days.
Test Range Values:
Normal cortisol levels in the morning: About 6 to 23 micrograms per deciliter (mcg/dL) or 166 to 635 nanomoles per liter (nmol/L).
What is the test?
This test measures cortisol levels in the morning, which helps assess adrenal gland function and diagnose conditions related to cortisol production, such as Addison’s disease or Cushing’s syndrome.
Test Procedure:
A blood sample is drawn in the morning (when cortisol levels are typically at their highest) and analyzed for cortisol levels in the laboratory.
When to take the test:
When evaluating adrenal gland function, diagnosing adrenal disorders, or assessing conditions related to cortisol levels.
Who should take the test:
Individuals with suspected adrenal gland disorders, symptoms of Addison’s disease or Cushing’s syndrome, or those with unexplained changes in cortisol levels might undergo this test.
Precautions for exceptional cases (pregnancy, etc.):
Pregnant individuals might experience altered cortisol levels; healthcare providers should consider this when interpreting results.
Frequently Asked Questions (FAQs) for Cortisol (am) Test:
Q1: Why is morning cortisol testing significant?
A: Cortisol levels follow a diurnal pattern, peaking in the morning and decreasing throughout the day. Morning testing provides a baseline level when it’s typically higher.
Q2: Can factors like stress or lifestyle affect morning cortisol levels?
A: Yes, stress, inadequate sleep, and certain medications or health conditions can influence cortisol levels.
Q3: What can low morning cortisol levels indicate?
A: Low levels might suggest adrenal insufficiency (Addison’s disease) or certain pituitary gland disorders affecting cortisol production.
Q4: How are abnormal cortisol levels treated?
A: Treatment depends on the underlying cause. It might involve hormone replacement therapy or addressing the specific condition causing the abnormal levels.
Q5: Can food or drink affect morning cortisol levels?
A: Generally, food and drink don’t significantly affect morning cortisol levels unless there’s a specific condition affecting cortisol regulation.
