This test is primarily used to diagnose pheochromocytoma, a rare type of cancer, and similar tumors which may secrete epinephrine, norepinephrine, or both.
Significant deviations from the normal range may require further evaluation by your physician.

Patient should avoid alcohol, coffee, tea, tobacco and strenuous exercise prior to collection. Patients should be relaxed in either a supine or upright position before blood is drawn. States of anxiety and stress can cause fluctuations in the catecholamine levels.
