Order Parathyroid Hormone (PTH) Test | Lab TestThe parathyroid glands regulate calcium balance through the release of parathyroid hormone, a peptide that acts on bone, kidney, and intestine. Measuring PTH in the blood provides a direct view of how these small glands are functioning and whether their output matches the body's calcium needs.
About Parathyroid Hormone (PTH) Test | Lab Test in Springfield
Parathyroid hormone is the primary regulator of calcium homeostasis.
PTH is secreted by four small parathyroid glands located behind the thyroid. When calcium levels fall, PTH rises to stimulate bone resorption, increase renal calcium reabsorption, and activate vitamin D, which in turn boosts intestinal calcium absorption.
A PTH test is typically ordered alongside calcium and sometimes phosphorus or vitamin D measurements. The relationship between PTH and calcium is central to interpretation: a high PTH with high calcium points toward primary hyperparathyroidism, while a high PTH with low calcium suggests a secondary cause such as kidney disease or vitamin D deficiency.
Results are reported in picograms per milliliter and are interpreted against the laboratory's reference range. Because PTH secretion is pulsatile and influenced by factors like time of day and recent meals, clinicians consider the full clinical picture rather than a single value.
