Cortisol Serum Evening Sample Test
Understanding Cortisol and Its Importance
Cortisol is a vital steroid hormone produced by the adrenal glands that plays a crucial role in numerous bodily functions, including stress response, metabolism regulation, blood pressure control, and immune system function. The Cortisol Serum Evening Sample Test specifically measures cortisol levels during the evening hours, typically between 3-5 PM, when cortisol concentrations should naturally be at their lowest point in the daily cycle.
This specialized timing is essential because cortisol follows a distinct diurnal pattern, peaking in the early morning and gradually declining throughout the day. Abnormal evening cortisol levels can indicate serious endocrine disorders that require immediate medical attention and proper management.
What the Test Measures and Detects
The Cortisol Serum Evening Sample Test utilizes advanced chemiluminescent immunoassay technology to precisely quantify cortisol concentrations in your blood serum. This sophisticated method provides highly accurate measurements that help healthcare providers assess:
- Adrenal gland function and cortisol production patterns
- Circadian rhythm integrity and hormonal timing
- Potential Cushing’s syndrome diagnosis
- Adrenal insufficiency or Addison’s disease
- Pituitary gland disorders affecting cortisol regulation
- Response to steroid medication treatments
Who Should Consider This Test
This test is particularly important for individuals experiencing symptoms that may indicate cortisol regulation issues. Consider scheduling a Cortisol Serum Evening Sample Test if you experience:

Understanding Your Test Results
Interpreting cortisol test results requires professional medical expertise, but here’s general guidance on what your results might indicate:
Normal Results
Normal evening cortisol levels typically range between 2-10 mcg/dL. Values within this range suggest proper adrenal function and normal circadian rhythm patterns.
Elevated Evening Cortisol
Higher than expected evening cortisol levels may indicate:
- Cushing’s syndrome or disease
- Adrenal tumors
- Pituitary gland disorders
- Chronic stress response
- Certain medications affecting cortisol production
Low Evening Cortisol
Lower than normal levels could suggest:
- Adrenal insufficiency (Addison’s disease)
- Pituitary gland dysfunction
- Long-term steroid use affecting natural production
- Chronic fatigue conditions
Always discuss your specific results with your healthcare provider for personalized interpretation and treatment recommendations.
