Catecholamines in Blood
Why It Is Done
A catecholamine test is done to help diagnose a tumor in the adrenal glands called a pheochromocytoma. Catecholamine levels in the blood can change quickly, so it may be hard to find high values in a single blood sample. But a special compound, metanephrine, may be found in the blood, which may mean a pheochromocytoma is present. Doctors may want to do a urine test that measures catecholamine levels over 24 hours.
