24 hour urine dopamine level is very high. the range is up to 500. my level was almost 700. what can cause this. all else normal (epinephrine, norepinephrine, metenephrine , etc) although plasma epinephrine was elevated 2 x range ? urine normal?

I assume you had these tests because of high blood pressure. I assume you're not taking any meds that can raise urinary dopamine. A study showed that elevated urinary dopamine alone wasn't diagnostic of pheochromocytoma. Elevated plasma epinephrine alone is nonspecific & seen in stress, vigorous exercise, alcohol use,smoking, caffeine excess. An endocrinologist can advise you best.
