The clonidine suppression test confers specificity to the clinical and laboratory findings, and magnetic resonance imaging is the most reliable method of
We evaluated clonidine suppression testing in patients with borderline elevated normetanephrine during screening for pheochromocytoma and paraganglioma
, cocaine, heroin) Once, it has been established that the adrenaline type
Pheochromocytoma is a rare tumor arising from chromaffin cells in adrenal medulla or other paraganglia in the body, which may be associated with many genetic syndromes
Provocative tests are contraindicated but the clonidine suppression test can be used in
If neither of these imaging studies shows a tumor, but lab tests confirm that one is present
Clonidine (Catapres) How does a positive clonidine suppression test detect Pheochromocytoma? In pts
Clonidine suppression caused decreases at 2 and 3 h to 372 and 408 pg/ml, respectively
Since the implementation of routine measurement of MN and NMN, CST has become less frequent in clinical practice
Another way to diagnose pheochromocytoma is with a clonidine suppression test
28 mumol (1 mg) glucagon, and in the Of 50 patients undergoing both glucagon stimulation and clonidine suppression tests, the results of at least one test were abnormal in 22 of 22 patients with pheochromocytoma (sensitivity 100%) and in 6 of 28 patients without pheochromocytoma (specificity 79%)
A pheochromocytoma is a catecholamine-secreting tumor of chromaffin cells typically located in the adrenals
What are four disease management areas the nurse should review with the patient?, A nurse is caring for a client undergoing a clonidine suppression test to identify for a pheochromocytoma

CONCLUSIONS Pheochromocytoma should be suspected in A pheochromocytoma is a tumor arising from adrenomedullary chromaffin cells that commonly produces one or more catecholamines: epinephrine, norepinephrine, and dopamine
Objective: The purpose of this paper is to report our experience and to review the published data on the diagnostic significance and risks of the clonidine suppression test in the diagnosis of pheochromocytoma
In approximately 60 percent of patients, the tumor is discovered incidentally during computed tomography (CT) or magnetic resonance imaging (MRI) of the abdomen for unrelated symptoms []
1 This tumor causes the continuous overproduction of epinephrine and the clonidine suppression test can help confirm a diagnosis
2% of individuals with hypertension
A woman with a genetic predisposition to pheochromocytoma was receiving venlafaxine, which can increase plasma metanephrine levels
The clonidine suppression test is quite safe and exceptionally reliable in differentiating neurogenic hypertension from pheochromocytic hypertension; 11,12 clonidine suppresses sympathetic nerve activity and plasma norepinephrine by more than 50% or to normal concentrations in neurogenic hypertension, but not in patients with
