Diagnosis typically involves clinical history, physical examination, and laboratory tests. The most common tests include:
ACTH Stimulation Test: Measures adrenal response to synthetic ACTH. Baseline Morning Cortisol: Low levels may indicate suppression. Insulin Tolerance Test: Assesses the entire HPA axis, though less commonly used in children due to risks.
Consulting a pediatric endocrinologist is often recommended for accurate diagnosis and management.
