The main causes of hypercalcaemia are primary hyperparathyroidism, malignant disease, and chronic renal failure. The differential diagnosis of hypercalcaemia depends on the clinical setting. Some patients with recurrent renal calculi have a high urinary calcium output, idiopathic hypercalciuria. Serum calcium must be checked to exclude hypercalcaemia.
