Intact PTH ELISA Kit Background Information:
Intact PTH assays are important for the differentiation of primary hyperparathyroidism from non-parathyroid-mediated forms of hypercalcemia, such as malignancy, sarcoidosis and thyrotoxicosis. The measurement of parathyroid hormone is the most specific way of making the diagnosis of primary hyperparathyroidism. In the presence of hypercalcemia, an elevated level of parathyroid hormone virtually establishes the diagnosis. In over 90% of patients with primary hyperparathyroidism, the parathyroid hormone will be elevated. Intact PTH is biologically active and clears very rapidly from the circulation with a half-life of less than four minutes. PTH undergoes proteolysis in the parathyroid glands, but mostly peripherally, particularly in the liver but also in the kidneys and bone, to give N-terminal fragments and longer lived C-terminal and mid-region fragments. In subjects with renal insufficiency, C-terminal and mid-region PTH assays typically give elevated PTH results, as reflected by impaired renal clearance.




Intact PTH ELISA Test Principle:
The Diagnostic Automation Intact PTH Immunoassay is a two-site ELISA assay for the measurement of the biologically intact 84 amino acid chain of PTH. Two different goat polyclonal antibodies to human PTH have been purified by affinity chromatography to be specific for well-defined regions on the PTH molecule. One antibody is prepared to bind only the mid-region and C-terminal PTH 39-84 and this antibody is biotinylated. The other antibody is prepared to bind only the N-terminal PTH 1-34 and this antibody is labeled with HRP for detection. For additional details please refer to the instructions for use.
