This test measures a substance called parathyroid hormone (PTH) in your blood. PTH is made by four tiny parathyroid glands in your neck. PTH circulates in your blood and is needed to regulate the level of calcium in your blood.
You must be diagnosed with parathyroid disease (hyperparathyroidism) if your parathyroid hormone level is high and your calcium level is also high. The excess parathyroid hormone is the CAUSE of the high calcium. The high calcium is caused by a parathyroid tumor--nothing else will cause this.owever... many people (about 20% of all patients with hyperparathyroidism) will have parathyroid disease when they have high calcium and NORMAL PTH levels... The point here is that the parathyroid gland is still the problem. This is a more complex situation, so we will discuss it at the end of this page.
