Addison's Disease Testing: ACTH and Cortisol Blood Levels
In patients suspected of having an
addisonian crisis, the doctor must begin treatment with injections of salt, fluids, and glucocorticoid hormones immediately. A reliable diagnosis is not possible while the patient is being treated for the addisonian crisis. However, measurement of blood ACTH and cortisol during the crisis and before glucocorticoids are given is enough to make the
Addison's disease diagnosis.
Once the addisonian crisis is controlled and medication has been stopped, the doctor will delay further Addison's disease testing for up to 1 month to obtain an accurate diagnosis.
Addison's Disease Testing: Imaging Tests
Once a diagnosis of Addison's disease has been made, x-ray exams of the abdomen may be taken to see if the adrenals have any signs of
calcium deposits. Calcium deposits may indicate
tuberculosis (TB). A tuberculin skin test also may be used.
