Pheochromocytoma: Sensitivity and Specificity

Introduction: Can be sporatic or hereditary (von Hippel-Lindau, MEN 2, and neurofibromatosis 1). Note that the sensitivities and specificities of the catecholamine tests differ between the two groups (JAMA 2002 Mar 20;287(11):1427-34. PMID: 11903030).

Untagged

Finding SensitivitySpecificity Comments, Study
Chromogranin A, Elevated Edit No accuracy specified.

Elevated in other neuroendocrine tumors as well

Study: no study specified.

Clonidine suppression test Edit No accuracy specified.

This is test is used to confirm a positive result of increased catecholamines in plasma or urine.

The clonidine suppression test is used to distinguish between pheochromocytoma and false-positive increases in plasma catecholamines and fractionated metanephrines.

Clonidine suppresses the release of catecholamines from neurons but does not affect the catecholamine secretion from a pheochromocytoma. (UpToDate)
