The three catecholamines (norepinephrine, epinephrine, and dopamine) are the principal secretory products of neural tissue. Clinically, the measurement of circulating catecholamines is valuable in the diagnosis of catecholamine secreting tumors associated chiefly with hypertension (pheochromocytomas, neuroblastomas, and gangliomas) and with the evaluation of orthostatic hypotension.
No special preparation is needed for Catecholamines. Inform your doctor if you are on any medications or have any underlying medical conditions or allergies before undergoing Catecholamines. Your doctor depending on your condition will give specific instructions.
