How should you evaluate elevated calcium in an asymptomatic patient?
Abstract
Patients with unexplained asymptomatic true hypercalcemia should be screened for primary hyperparathyroidism (PHPT) and malignancy using an intact parathyroid hormone (PTH) level by immunoradioassay (SOR: C, expert opinion). Other recommended tests that can distinguish PHPT from malignancy and familial hypocalciuric hypercalcemia, as well as help manage patients with PHPT include urinary 24-hour calcium and creatinine levels, parathyroid hormone related peptide (PTHrP), alkaline phosphatase, calcitriol, and bone densitometry (SOR: C, expert opinion).
