PTH (Parathyroid Hormone) is a protein hormone produced by the parathyroid glands located behind the thyroid. It plays a critical role in maintaining normal blood calcium and phosphorus levels by acting on bones, kidneys, and intestines. When blood calcium levels drop, PTH secretion increases to: -Release calcium from bones -Increase calcium reabsorption in the kidneys while decreasing phosphorus excretion. -Activate vitamin D in the kidneys, PTH measurement is used to diagnose and monitor hyperparathyroidism or hypoparathyroidism and to assess causes of calcium and phosphorus imbalances.
