The Parathyroid Glands, Primary and Secondary Hyperparathroidism and Assays for Parathyroid Hormone (Clinical Report‪)‬

Background The four parathyroid glands are bean-sized organs found in the neck near the thyroid gland. These glands synthesize parathyroid hormone (PTH or parathormone) which helps the body to use and store calcium and to maintain the calcium levels in the blood within normal limits. Actually, as far as we know, the only role of PTH is in calcium homeostasis.
