Addison's Disease | Testing and Diagnosis

How is Addison’s disease diagnosed?

Symptoms for Addison’s disease often come on slowly. In addition to a complete medical history and physical examination, diagnostic procedures for Addison's disease may include:
  • laboratory blood tests to measure levels of corticosteroid hormone (cortisol) and the pituitary hormone ACTH, which regulates adrenal gland function
  • an ACTH stimulation test to assess adrenal gland function
  • measurement of electrolytes in the blood

Based on the results of these tests, your child’s doctor will be able to definitively diagnose whether your child has Addison’s disease.
