What does a catecholamine test show?
A catecholamines test uses a sample of your blood or urine to measure levels of certain adrenal hormones. You may need this test if you’re experiencing symptoms of rare adrenal tumors, like neuroblastoma, paraganglioma or pheochromocytoma.

The following normal values are the amount of the substance found in the urine over a 24-hour period: Dopamine: 65 to 400 micrograms (mcg)/24 hours (420 to 2612 nmol/24 hours) Epinephrine: 0.5 to 20 mcg/24 hours. Metanephrine: 24 to 96 mcg/24 hours (some laboratories give the range as 140 – 785 mcg/24 hours)
What do catecholamines do?

Can catecholamines cause heart failure?
High and rising catecholamine levels are associated with worsening of prognosis in patients with heart failure. These patients show a decreased beta-receptor number and cellular concentration of catecholamines. On the other hand cardiomyopathy is associated with an increased sensitivity to catecholamines.
What effect do catecholamines have on blood pressure?

- surgery to remove the tumor and possibly the adrenal glands.
