This test is used to help identify hyperparathyroidism, to find the cause of abnormal calcium levels, or to check the status of chronic kidney disease.PTH controls calcium and phosphorus levels in the blood.arathyroid Hormone.

The level of calcium in blood is regulated primarily by two hormones: parathyroid hormone and calcitonin. Parathyroid hormone is produced by the four parathyroid glands, located around the thyroid gland in the neck. When the calcium level in blood decreases, the parathyroid glands produce more parathyroid hormone.timulates the digestive tract to absorb more calcium. Causes the kidneys to activate vitamin D, which enables the digestive tract to absorb more calcium. Calcitonin is produced by cells of the thyroid gland. It lowers the calcium level in blood by slowing the breakdown of bone, but only slightly.
