In the traditional workup, an effort is made to formally study the exact cause of the hypercalciuria. Using this approach, a calcium-loading test is performed; results include the following:

  • Absorptive hypercalciuria - After calcium loading, periodically obtained urine samples tend to show a great increase in the patient’s urinary calcium excretion

  • Renal leak hypercalciuria - After calcium loading, patients do not demonstrate as large an increase in urinary calcium as do those with absorptive hypercalciuria
