PTHrP; PARATHYROID HORMONE RELATED PEPTIDE
Hypercalcemia of malignancy is a common cause of hypercalcemia specially in hospitalized patients. This is typically not due to excess of PTH hormone, but due to the presence of PTHrP. This assay is used as a diagnostic workup of patients with suspected hypercalcemia of malignancy and hypercalcemia of unknown origin. This test should not be used to exclude cancer or screen tumor patients for humoral hypercalcemia of malignancy.
