Commonly Performed Diagnostic Tests for Adrenal Gland Function

The adrenal glands play a crucial role in hormone regulation, impacting metabolism, immune response, and stress management. Proper diagnostic testing is essential for detecting disorders affecting adrenal function.

1. Overview of Adrenal Gland Function Tests

These tests help evaluate hormone production, detect deficiencies or excesses, and diagnose disorders such as Addison’s disease or Cushing’s syndrome.

2. Types of Adrenal Function Tests

• Cortisol Test: Measures cortisol levels in blood, urine, or saliva to diagnose adrenal insufficiency or overproduction.
• ACTH Stimulation Test: Evaluates adrenal response to adrenocorticotropic hormone (ACTH) stimulation.
• Dexamethasone Suppression Test: Identifies abnormal cortisol production and helps diagnose Cushing’s syndrome.
• Aldosterone and Renin Test: Assesses aldosterone production, helping diagnose primary aldosteronism.
• Adrenal Imaging: CT scans and MRI aid in detecting tumors or structural abnormalities.

3. Clinical Significance

Abnormal adrenal hormone levels can lead to metabolic imbalances, hypertension, and chronic fatigue. Timely diagnosis and treatment are vital for managing adrenal disorders effectively.

4. Interpretation of Test Results

Results are analyzed based on patient symptoms, medical history, and additional laboratory findings. Consulting an endocrinologist is recommended for an accurate diagnosis.

Conclusion

Adrenal gland function tests provide essential insights into endocrine health. Regular monitoring ensures early intervention and optimal patient care.
