Order Parathyroid Hormone (PTH) Test | Lab TestThe parathyroid glands are small endocrine structures that sit behind the thyroid in the neck. Despite the similar name, they are unrelated to the thyroid in function. Their primary job is to release parathyroid hormone, or PTH, which regulates calcium and phosphorus levels in the blood and bone. A PTH test measures the amount of this hormone circulating in the bloodstream.
About Parathyroid Hormone (PTH) Test | Lab Test in Antioch
PTH testing is typically ordered when calcium results are abnormal or when a parathyroid disorder is suspected.
PTH is part of a feedback loop involving the parathyroid glands, bones, kidneys, and intestines. When blood calcium drops, the glands release more PTH, which prompts the kidneys to conserve calcium, activates vitamin D, and stimulates bone to release calcium. When calcium rises, PTH production should fall.
Because of this relationship, PTH is rarely interpreted on its own. Clinicians usually evaluate it alongside a simultaneous calcium measurement, and sometimes phosphorus, vitamin D, and kidney function markers. The pattern of results helps distinguish primary hyperparathyroidism, secondary hyperparathyroidism, and other conditions that affect calcium balance.
The test requires a standard blood draw, and no special diet is usually needed beyond any instructions provided by the laboratory. Results are typically available within a few business days. Reference ranges vary by laboratory, so results should be reviewed in the context of the testing facility's own ranges and the patient's overall clinical picture.
