Cortisol Stimulation by ACTH Test
Understanding Adrenal Function Testing
The Cortisol Stimulation by ACTH Test represents a cornerstone diagnostic procedure in modern endocrinology, specifically designed to evaluate the functional capacity of your adrenal glands. This sophisticated test measures how effectively your adrenal cortex responds to adrenocorticotropic hormone (ACTH) stimulation, providing critical insights into your body’s stress response system and cortisol production capabilities.
What Does This Test Measure?
This comprehensive diagnostic assessment evaluates:
- Baseline cortisol levels before ACTH administration
- Cortisol response at 30 minutes post-stimulation
- Cortisol levels at 60 minutes following ACTH injection
- Adrenal gland reserve capacity and responsiveness
- The integrity of the hypothalamic-pituitary-adrenal (HPA) axis
Who Should Consider This Test?
This test is particularly recommended for individuals experiencing:
- Unexplained fatigue and weakness
- Persistent dizziness or lightheadedness
- Unexpected weight loss or poor appetite
- Skin hyperpigmentation or darkening
- Low blood pressure episodes
- Salt cravings and electrolyte imbalances
- Suspected adrenal insufficiency symptoms
- Monitoring adrenal function in autoimmune conditions
Clinical Benefits of Cortisol Stimulation Testing
Undergoing this comprehensive adrenal assessment provides numerous advantages:
- Early detection of adrenal insufficiency disorders
- Accurate differentiation between primary and secondary adrenal failure
- Monitoring adrenal function during steroid therapy
- Assessment of adrenal reserve in critical illness
- Guidance for appropriate hormone replacement therapy
- Peace of mind through definitive diagnostic clarity
Understanding Your Test Results
Your results will be interpreted by our board-certified endocrinologists:
- Normal Response: Cortisol levels typically double from baseline, indicating healthy adrenal function
- Suboptimal Response: May suggest adrenal insufficiency or impaired reserve
- Exaggerated Response: Could indicate certain forms of Cushing’s syndrome
- Flat Response: Often characteristic of primary adrenal failure
All results include comprehensive explanations and recommendations for follow-up care.
