High levels may indicate pheochromocytoma, a rare tumor, or other conditions causing excessive hormone production. Low levels can suggest adrenal insufficiency or other health issues that suppress hormone production.
What are the signs and symptoms of the issue the test is testing for?
Signs and symptoms might include severe headaches, excessive sweating, rapid heartbeat, and high blood pressure among others.
How often should I retest?
Retesting frequency depends on the initial results and underlying condition. Your healthcare provider will recommend when it is appropriate to retest based on your specific circumstances.
How accurate is the test?
This test is highly accurate when collecting the urine sample according to guidelines. It is critical to follow pre-test instructions to ensure reliable results.
What are the test preparations?
Avoid stress before blood draw. Many drugs (reserpine and alpha methyldopa, levodopa, monoamine oxidase inhibitors, and sympathomimetic amines) may interfere and should be discontinued two weeks before specimen collection. Nose drops, sinus and cough medicines, bronchodilators and appetite suppressants, α2-agonists, calcium channel blockers, converting enzyme inhibitors, bromocriptine, phenothiazine, tricyclic antidepressants, α- and β-blockers, and labetalol may interfere. Mandelamine® interferes, but thiazides do not. Caffeine products should be avoided before and during collection. The patient should not be subjected to hypoglycemia or exertion. Increased intracranial pressure and clonidine withdrawal can cause false-positive results.
