Order Parathyroid Hormone (PTH) Test | Lab TestThe parathyroid hormone (PTH) test measures the amount of PTH in the blood. PTH is produced by the parathyroid glands, four small glands located near the thyroid in the neck. This hormone is central to calcium regulation: it raises blood calcium when levels fall by acting on bone, the kidneys, and the intestines. Because PTH and calcium are so tightly linked, the test is most informative when interpreted alongside a calcium measurement.
About Parathyroid Hormone (PTH) Test | Lab Test in Orangevale
PTH testing is used to evaluate parathyroid function and calcium balance.
PTH is secreted in response to low blood calcium. It stimulates release of calcium from bone, increases calcium reabsorption in the kidneys, and activates vitamin D, which in turn increases calcium absorption from the gut. When calcium rises, PTH secretion normally falls, creating a negative feedback loop.
A PTH test is typically ordered when a calcium result is abnormal, or when a person has symptoms or conditions that suggest a parathyroid disorder, such as kidney stones, bone loss, or unexplained fatigue. The results are usually interpreted with a simultaneous calcium level, and sometimes with vitamin D and phosphate.
High PTH with high calcium points toward primary hyperparathyroidism, while high PTH with low calcium can indicate secondary hyperparathyroidism, often related to kidney disease or vitamin D deficiency. Low PTH with high calcium suggests a different cause, such as a non-parathyroid source of calcium elevation. Because of this interdependence, a single PTH value is rarely interpreted in isolation.
