Hypercalcemia can be caused by a variety of factors, including hyperparathyroidism, cancer, vitamin D toxicity, and several other conditions. Measuring the level of parathyroid hormone (PTH) can help determine whether the cause of hypercalcemia is related to overproduction of PTH by the parathyroid glands (as in primary hyperparathyroidism) or some other underlying condition.
