What tests are used to diagnose adrenal tumors?

Blood tests will be completed. A test of the cortisol levels may be done. Urine may need to be collected for 24 hours. A biopsy of the tumor may be completed to determine whether or not the tumor is malignant. Magnetic resonance imaging (MRI) or computed tomography (CT) scans may be used. Other tests may include adrenal vein sampling or a metaiodobenzylguanidine (MIBG) scan. If the tumor is cancerous, the tumor will be staged, which includes the size and location of the tumor; whether it has spread to the lymph nodes; and whether it has spread to other parts of the body.
