Overview

Parathyroid hormone (PTH) is a peptide produced by the parathyroid gland. PTH principally serves in the maintenance of calcium homeostasis; thus, assessment of PTH can be an important diagnostic aid for diagnosis of calcium metabolism disorders. In healthy individuals, PTH is secreted from the parathyroid gland as a negative feedback response to circulating calcium ion levels. The half-life of intact PTH is 2 to 5 minutes.

Hypercalcemia may be due to hyperparathyroidism, a group of conditions characterized by an overproduction of PTH. Hyperparathyroidism is separated into primary, secondary, and tertiary causes. Primary hyperparathyroidism is most frequently due to a parathyroid tumor (usually benign) that secretes PTH without feedback control, leading to hypercalcemia, kidney stones, calcium deposits in organs, and decalcification of bone. With primary hyperparathyroidism, patients will generally have high calcium and high PTH levels, while phosphate levels are often low.

Secondary hyperparathyroidism is usually due to kidney failure. In secondary hyperparathyroidism, patients will generally have high PTH levels and low or normal calcium levels. Sometimes, persons with secondary hyperparathyroidism develop high serum calcium and still have high PTH; this is sometimes called tertiary hyperparathyroidism.

Hypocalcemia may be due to hypoparathyroidism or a failure of the parathyroid gland to produce sufficient PTH. Hypoparathyroidism may be due to a variety of conditions and may be persistent, progressive, or transient. Causes include an autoimmune disorder, parathyroid damage or removal during surgery, a genetic condition, and severe illnesses. Affected patients will generally have low PTH levels and low calcium levels and will also have high phosphate levels.

Note: because of the physiological relationship of circulating calcium and PTH, it is always important to interpret PTH results in association with serum calcium.

Clinical Utility
  • Diagnosis of hypercalcemia due to primary hyperparathyroidism related to parathyroid tumors
  • Diagnosis hypercalcemia due to secondary hyperparathyroidism related to kidney disorders, malabsorption, and other calcium metabolic disorders
  • Diagnosis of hypocalcemia due to hypoparathyroidism related to autoimmune disorders, injuries, surgery, and other related disorders

Interpretation
