Order Parathyroid Hormone (PTH) Test | Lab TestThe parathyroid hormone test measures the amount of parathyroid hormone (PTH) circulating in the blood. PTH is produced by the parathyroid glands, four small glands located behind the thyroid, and it plays a central role in regulating calcium and phosphorus balance. Because PTH works in close feedback with calcium, a PTH result is usually interpreted alongside a calcium measurement rather than on its own.
About Parathyroid Hormone (PTH) Test | Lab Test in La Puente
This test is used to evaluate parathyroid function and to help investigate disorders of calcium homeostasis.
PTH acts on bone, the kidneys, and the intestine to keep blood calcium within a narrow range. When calcium falls, PTH secretion typically rises; when calcium rises, PTH secretion normally falls. A PTH level that does not fit this expected relationship can point to a parathyroid or calcium-regulation problem.
Clinicians order a PTH test to help distinguish primary hyperparathyroidism, in which the parathyroid glands release too much hormone, from other causes of elevated calcium. It is also used in the workup of hypocalcemia, chronic kidney disease, vitamin D disorders, and some cases of osteoporosis or unexplained bone loss.
Results are reported in picograms per milliliter (pg/mL), though reference ranges vary by laboratory and by the assay method used. A single value is rarely diagnostic by itself, so the ordering provider considers PTH together with calcium, phosphorus, vitamin D, kidney function, and the clinical picture.
