This test measures the level of cortisol in the body half an hour after a specific injection. Cortisol is a hormone produced by the adrenal glands that helps regulate various bodily functions, including metabolism, immune response, and stress management. The test helps in assessing adrenal gland function and diagnosing conditions such as Addison's disease, Cushing's syndrome, and adrenal insufficiency. It involves administering a corticotropin-releasing hormone (CRH) injection, followed by blood sample collection after 30 minutes to measure cortisol levels.

How our test process works!
The cortisol level 0.5-hour after injection test is a diagnostic tool often used in an ACTH stimulation test or a dexamethasone suppression test. These tests evaluate adrenal gland function and assess the hypothalamic-pituitary-adrenal (HPA) axis for disorders like Addison’s disease or Cushing’s syndrome.
Purpose
- ACTH Stimulation Test: Measures cortisol response after synthetic ACTH injection to check adrenal gland function.
- Dexamethasone Suppression Test: Assesses cortisol suppression following dexamethasone administration, to evaluate for conditions like hypercortisolism (e.g., Cushing's syndrome).
Risk Assessment
- Minimal risks:
- Mild discomfort or bruising at the blood draw site.
- Rare allergic reactions to the injected agent (ACTH or dexamethasone).
- Precautions:
- Patients with bleeding disorders or anticoagulant therapy should notify their doctor before testing.
- Ensure proper medical supervision during and after the test.
Normal Range (30 minutes post-injection)
-
ACTH Stimulation Test:
- Cortisol levels: >18-20 µg/dL (500-550 nmol/L) at 30 minutes post-injection.
- Adrenal Insufficiency: Levels below this threshold suggest impaired adrenal function.
-
Dexamethasone Suppression Test:
- Suppressed cortisol levels (<1.8 µg/dL or <50 nmol/L) indicate normal suppression.
- Higher levels may indicate hypercortisolism.
Interpretation of Results
-
ACTH Stimulation Test:
- Normal Response: A robust rise in cortisol levels (>18-20 µg/dL).
- Suboptimal Response: Indicates adrenal insufficiency (primary or secondary).
-
Dexamethasone Suppression Test:
- Normal Suppression: Confirms no HPA hyperactivity.
- Lack of Suppression: Suggestive of conditions like Cushing’s syndrome or ectopic ACTH production.
Sample Type
- Serum Sample: Collected via venipuncture.
- Timing is critical—samples are drawn 30 minutes after the injection.
