Catecholamine-Urine (Random) is a urine test that measures levels of catecholamines, including adrenaline (epinephrine), noradrenaline (norepinephrine), and dopamine. These hormones are produced by the adrenal glands and nervous system and help regulate the body’s response to stress. The test is needed to investigate unusually high catecholamine levels and support the evaluation of conditions such as pheochromocytoma and other disorders affecting catecholamine production.
Pheochromocytoma is a rare tumor arising from specialized cells, usually in the adrenal glands, that can produce excessive catecholamines and cause episodes of high blood pressure and other symptoms.
Yes. Physical or emotional stress can temporarily increase catecholamine production and may influence test results. Your healthcare provider will consider this when interpreting the findings.
Elevated catecholamines can have several causes, including stress, medications, certain foods, and medical conditions. Persistently significant elevations may require further evaluation for a catecholamine-producing tumor.
Not necessarily. Interpretation depends on the type of test, degree of elevation, symptoms, and clinical suspicion. Additional testing, such as plasma or urine metanephrines, may sometimes be recommended.
Catecholamines are the active hormones themselves, while metanephrines are breakdown products of these hormones. Metanephrine testing is often preferred for evaluating suspected pheochromocytoma because it can be more sensitive.
