Parathyroid hormone. Parathyroid hormone (PTH), also called parathormone or parathyrin, is a hormone secreted by the parathyroid glands that is important in bone remodeling, which is an ongoing process in which bone tissue is alternately resorbed and rebuilt over time. It essentially increases blood calcium levels.
PTH stands for parathyroid hormone. It is a protein hormone released by the parathyroid gland. The parathyroid glands are located in the neck, near or attached to the back side of the thyroid 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.A laboratory test can be done to measure the amount of PTH in your blood.TH stands for parathyroid hormone.
