Parathyrin
Active
Descriptions
A substance made by the parathyroid gland that helps the body store and use calcium. A higher-than-normal amount of parathyrin causes high levels of calcium in the blood and may be a sign of disease. Also called parathormone, parathyroid hormone, and PTH. Source: National Cancer Institute, Parathyrin
Parathyrin intact (iPTH) levels are requested for the differential diagnosis of calcium-related abnormalities. The test is useful for diagnosis of primary hyperparathyroidism, secondary hyperparathyroidism, and differential diagnosis of hypercalcemia. Because there are many fragments of PTH, tests for PTH may measure one or more of the fragments. None of the assays for intact PTH measure PTH (35-84), which is actually the fragment of PTH present in highest amounts in blood. Many intact PTH assays measure either PTH (1-84) or PTH (7-84). In most people, PTH (7-84) is present in much lower amounts than PTH (1-84), so this is not a concern. But in kidney failure, PTH (7-84) levels increase compared to PTH (1-84), and sometimes over half of what is measured as PTH represents this N-terminal truncated fragment. Some intact PTH assays do not measure this fragment and will give lower PTH results when increased PTH (7-84) is present. Copyright Copyright © 2021 Lab Tests Online. All rights reserved.
