If the urine potassium level is higher than 40 mEq/L, consider diuretics. If diuretic use has been excluded, measure arterial blood gases (ABG) and determine the acid-base balance. Alkalosis suggests one of the following:

  • Vomiting

  • Bartter syndrome

  • Gitelman syndrome

  • Mineralocorticoid excess
