Simplified workup

  • Complete a medical history

  • Carry out initial blood and 24-hour urine testing

  • Identify hypercalciuric patients

  • Check hypercalcemic patients for hyperparathyroidism with parathyroid hormone (PTH) levels; consider a thiazide challenge test if the PTH level alone is inconclusive

  • Check hypophosphatemic patients for hyperphosphaturia and possible renal phosphate leak hypercalciuria; verify the diagnosis by determining of the vitamin D3 level or with a clinical trial of orthophosphate therapy

  • Start a therapeutic trial of dietary modification treatment

  • Repeat the blood and 24-hour urine tests

See Workup for more detail.
