A doctor may order a series of tests to rule out Addison's Disease, including blood tests, imaging tests, and adrenal function tests. Blood tests are used to measure certain hormones such as cortisol, aldosterone, and adrenocorticotropic hormone (ACTH). Imaging tests may include a CT scan or MRI to look for any abnormalities in the adrenal glands. Adrenal function tests measure how well the adrenal glands are producing hormones. These tests may include a 24-hour urine collection test or a Synacthen test.
These tests can help diagnose Addison's Disease by looking for an imbalance of hormones and abnormal changes in the adrenal glands. If the results of these tests indicate Addison’s Disease, further tests may be ordered to confirm the diagnosis, such as an ACTH stimulation test or a cosyntropin stimulation test. These tests measure the level of cortisol produced by the adrenal glands when stimulated by ACTH.
By ordering these types of tests, doctors can accurately diagnose Addison’s Disease and develop a treatment plan that is tailored to the individual’s needs. It is important to note that the results of these tests may not be conclusive and further tests may be necessary to confirm the diagnosis.
