Why It’s Done
Doctors may order the Epinephrine Urine Test to:
• Diagnose pheochromocytoma: This is a rare tumor of the adrenal glands that causes overproduction of catecholamines, including epinephrine.
• Evaluate stress response: Chronic elevated epinephrine levels may indicate stress-related disorders, such as anxiety, chronic stress, or certain heart conditions.
• Assess adrenal function: The test may be part of an evaluation for adrenal gland disorders, such as Cushing’s syndrome or adrenal insufficiency.
• Monitor patients with known adrenal disorders to assess whether epinephrine levels are normalized with treatment.
• Investigate symptoms like high blood pressure, palpitations, sweating, or severe headaches, which are consistent with high levels of epinephrine in the blood.
Preparation
• Diet and Medication: Your doctor may ask you to avoid certain foods, beverages, or medications that can affect catecholamine levels in the urine. For example, foods containing tyrosine (like bananas, chocolate, or cheese) and certain medications (such as monoamine oxidase inhibitors (MAOIs)) can interfere with the test results.
• Collection instructions: This test typically requires a 24-hour urine collection, meaning you will collect all your urine over a 24-hour period in a special container. It’s important to follow the exact instructions for urine collection to ensure accurate results.
• Hydration: Ensure you stay properly hydrated during the collection period, unless otherwise instructed by your healthcare provider.
