Order Parathyroid Hormone (PTH) Test | Lab TestThe parathyroid hormone (PTH) test measures the amount of parathyroid hormone in the blood. PTH is produced by the parathyroid glands, four small glands located behind the thyroid gland in the neck. This hormone is the primary regulator of calcium levels in the blood and plays a central role in bone metabolism and mineral balance.
About Parathyroid Hormone (PTH) Test | Lab Test in Plainfield
Parathyroid hormone testing is typically ordered when a person has abnormal calcium levels or symptoms that suggest a parathyroid disorder.
PTH works by increasing calcium in the blood through several mechanisms: it stimulates the release of calcium from bone, increases calcium absorption in the kidneys, and activates vitamin D to enhance calcium uptake from the intestines. When calcium levels fall, the parathyroid glands release more PTH; when calcium levels rise, PTH secretion decreases. This feedback loop keeps calcium within a narrow range.
A PTH test is often interpreted alongside a simultaneous calcium measurement. Elevated PTH with high calcium can indicate primary hyperparathyroidism, while elevated PTH with low calcium may point to secondary hyperparathyroidism, often related to kidney disease or vitamin D deficiency. Low PTH with high calcium can suggest a condition such as hypercalcemia of malignancy or an overactive thyroid.
Because PTH is unstable in blood, the sample must be handled carefully, and results are typically available within a few business days. Reference ranges vary by laboratory, so results should always be evaluated in the context of the patient's clinical picture and other laboratory findings.
