About the product
Elecsys PTH STAT (Roche code CPS_000507) is an immunoassay used for the in vitro quantitative determination of intact parathyroid hormone in human serum and plasma. The Roche product page states that the test is defined for the differential diagnosis of hypercalcemia and hypocalcemia and can be used intraoperatively. The method is described as electrochemiluminescence immunoassay (ECLIA).
Measured parameter and clinical significance
According to MedlinePlus, parathyroid hormone (PTH) is produced by the four small parathyroid glands in the neck. When blood calcium falls, PTH rises and brings about release of calcium from bones, absorption of calcium from the intestine and retention of calcium in the kidneys. When calcium returns to normal, PTH production decreases. Because of this relationship, blood calcium is usually requested together with PTH. MedlinePlus also refers to the test as parathormone or intact PTH. The sample is venous blood drawn from a vein in the arm, and preparation is usually not required. Some healthcare facilities may ask for fasting or for sampling at a particular time of day.
MedlinePlus states that the test may be requested for abnormal calcium results, in monitoring chronic kidney disease, and in checking the treatment of a parathyroid disease or surgery. High PTH with high calcium can be associated with primary hyperparathyroidism, high PTH with low calcium with secondary hyperparathyroidism, and low PTH with low calcium with hypoparathyroidism.
