Primary hyperparathyroidism (PHPT) is most often detected as hypercalcemia in an asymptomatic patient during routine blood work. Knowing the appropriate work-up of hypercalcemia is essential, since untreated PHPT can have significant complications affecting multiple organ systems—most notably, renal and musculoskeletal. Parathyroidectomy is curative in up to 95% of cases, but prevention of long-term complications relies on prompt recognition and appropriate follow-up.
