From the expert

The parathyroid hormone (PTH) is produced by a cluster of four small tiny glands which lie directly behind the thyroid glands. Parathyroid hormone regulates calcium levels in the blood, helping to increase levels when they are too low. If parathyroid hormone levels are too high or too low, this can affect bone and kidney health as well as affecting vitamin D levels.

Parathyroid hormone regulates calcium levels through mobilising calcium into the blood from bone, enhancing the absorption of calcium from the small intestine and controlling the amount of calcium lost in urine. This test identifies any over activity in the glands producing parathyroid hormone (PTH), while finding the cause of any abnormal blood calcium levels.
