Answer

Test selection criteria include the following:

  • Use plasma metanephrine testing in patients at high risk (ie, those with predisposing genetic syndromes or a family or personal history of pheochromocytoma)
  • Use 24-hour urinary collection for catecholamines and metanephrines in patients at lower risk
