In those patients with a plasma norepinephrine of less than 2000 pg/ml, the clonidine suppression test is 92% accurate in diagnosing pheochromocytoma when the normal. Patients who have relatively low baseline catecholamines levels (< 1000 pg/ml) may have high false positive test results if criteria less than 50 % reduction on norepinephrine levels is used. The clonidine suppression test for plasma levels of adrenaline and noradrenaline is done to confirm the presence of a pheochromocytoma. Tricyclic antidepressants and phenoxybenzamine accounted for 41% of.
