PTH stands for parathyroid hormone. It is a protein hormone released by the parathyroid gland. Parathyroid hormone controls calcium, phosphorus, and vitamin D levels in the blood and bone. Release of PTH is controlled by the level of calcium in the blood. Low blood calcium levels cause increased PTH to be released, while high blood calcium levels block PTH release.
