Whole Parathyroid Hormone (PTH) test system is a device intended to measure parathyroid hormone in plasma and serum. PTH measurements are used in the differential diagnosis of hypercalcemia (abnormally high levels of calcium in the blood) and hypocalcemia (abnormally low levels of calcium in the blood) resulting from disorders of calcium metabolism. ## Device Story The Whole PTH Immunoradiometric (IRMA) Tube Assay is an in vitro diagnostic test system used to quantify parathyroid hormone levels in human plasma or serum samples. The device utilizes an immunoradiometric assay (IRMA) principle, where PTH in the patient sample is captured and labeled with radioactive markers to produce a signal proportional to the hormone concentration. The assay is performed in a laboratory setting by trained technicians. Healthcare providers use the resulting PTH concentration values to aid in the differential diagnosis of calcium metabolism disorders, specifically hypercalcemia and hypocalcemia. By providing accurate hormone quantification, the device assists clinicians in identifying the underlying cause of calcium imbalances, thereby guiding appropriate therapeutic interventions for patients. ## Clinical Evidence No clinical data provided; bench testing only. ## Technological Characteristics Immunoradiometric assay (IRMA) tube-based system. Measures parathyroid hormone in plasma and serum. In vitro diagnostic device. Class II, Product Code CEW. ## Regulatory Identification A parathyroid hormone test system is a device intended to measure the levels of parathyroid hormone in serum and plasma. Measurements of parathyroid hormone levels are used in the differential diagnosis of hypercalcemia (abnormally high levels of calcium in the blood) and hypocalcemia (abnormally low levels of calcium in the blood) resulting from disorders of calcium metabolism. ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).
