The LIAISON® N-TACT® PTH Gen II is an in vitro chemiluminescent immunoassay (CLIA) intended for the quantitative
determination of intact human parathyroid hormone in serum, EDTA and Lithium Heparin plasma samples.
Measurements of parathyroid hormone levels are used in the differential diagnosis of hypercalcemia and hypocalcemia
resulting from disorders of calcium metabolism.
