High levels of catecholamines, vanillylmandelic acid (VMA), or metanephrine can mean that an adrenal gland tumor (pheochromocytoma) or another type of tumor that makes catecholamines is present.
What does a catecholamine test measure?
Epinephrine is also known as adrenaline. Catecholamine tests measure the amount of these hormones in your urine or blood. Higher than normal levels of dopamine, norepinephrine, and/or epinephrine can be a sign of a serious health condition.

Why catecholamines test is done?
The catecholamine blood test determines whether the level of catecholamines in your blood is too high. Most likely, your doctor has ordered a catecholamine blood test because they’re concerned that you might have a pheochromocytoma. This is a tumor that grows on your adrenal gland, where catecholamines are released.
What is normal catecholamine level?
Normal Results The normal range for epinephrine is 0 to 140 pg/mL (764.3 pmol/L). The normal range for norepinephrine is 70 to 1700 pg/mL (413.8 to 10048.7 pmol/L). The normal range for dopamine is 0 to 30 pg/mL (195.8 pmol/L). Note: Normal value ranges may vary slightly among different laboratories.
What is a high level of norepinephrine?
Bursts of norepinephrine can lead to euphoria (very happy) feelings but are also linked to panic attacks, elevated blood pressure, and hyperactivity. Low levels can cause lethargy (lack of energy), lack of concentration, attention deficit hyperactivity disorder (ADHD), and possibly depression.

What are catecholamines hormones symptoms?
Pheochromocytomas secrete catecholamine hormones (adrenaline and related hormones) that are responsible for the characteristic symptoms. Headache, sweating, and a fast heartbeat are typical symptoms, usually in association with markedly high blood pressure. About 10% of pheochromocytomas are malignant. Surgery is the treatment of choice.
What are catecholamines functions?

What are catecholamine levels?
