Cortisol Suppression by Dexamethasone Overnight Low Dose Test
Understanding the Cortisol Suppression Test
The Cortisol Suppression by Dexamethasone Overnight Low Dose Test is a specialized diagnostic procedure designed to evaluate adrenal gland function and detect abnormalities in cortisol regulation. This test plays a critical role in diagnosing Cushing’s syndrome, a condition characterized by excessive cortisol production that can lead to serious health complications if left untreated.
What Does This Test Measure?
This test specifically measures your body’s response to dexamethasone, a synthetic glucocorticoid that normally suppresses cortisol production in healthy individuals. The test evaluates:
- Cortisol suppression capability
- Adrenal gland responsiveness
- Hypothalamic-pituitary-adrenal (HPA) axis function
- Potential cortisol overproduction
Who Should Consider This Test?
This test is recommended for individuals experiencing symptoms that may indicate cortisol imbalance or adrenal dysfunction:
- Unexplained weight gain, particularly in the face and abdomen
- High blood pressure that’s difficult to control
- Muscle weakness and fatigue
- Mood changes, anxiety, or depression
- Irregular menstrual cycles in women
- Skin changes including thinning, bruising, or stretch marks
- Elevated blood sugar levels
- Decreased libido
Clinical Benefits of Testing
Undergoing the Cortisol Suppression Test provides numerous advantages for your health management:
- Accurate Diagnosis: Helps differentiate between various causes of cortisol excess
- Early Detection: Identifies adrenal disorders before they cause significant damage
- Treatment Guidance: Provides essential information for developing effective treatment plans
- Monitoring Tool: Can be used to track treatment effectiveness over time
- Peace of Mind: Either confirms or rules out serious adrenal conditions
Test Procedure and Preparation
Pre-Test Instructions
- Take the 1 mg dexamethasone tablet orally at exactly 11 pm
- Return to the testing facility the next morning at 8 am for blood draw
- Do not take any steroid medications before the test
- Follow any additional instructions from your healthcare provider
Sample Collection
The test requires 2 mL of serum collected in one SST tube. Samples are shipped refrigerated or frozen to ensure accuracy.
Understanding Your Test Results
Your test results will help your endocrinologist interpret your adrenal function:
- Normal Suppression: Cortisol levels decrease appropriately, indicating normal HPA axis function
- Inadequate Suppression: Suggests possible Cushing’s syndrome requiring further evaluation
- Borderline Results: May indicate the need for additional testing or monitoring
Always discuss your results with your healthcare provider for proper interpretation and next steps.
