What is calcium?

Calcium is the fifth most abundant element in the body. Most of it in the human adult is extracellular and 99% of it exists as crystalline hydroxyapatite in bones and teeth where it confers rigidity. It plays a major role in the mechanisms of nerve impulse transmission, muscular contraction and blood coagulation. Secretion from the parathyroid glands, thyroid C cells and pancreatic B cells is controlled by the extracellular ionised calcium concentration at the cell surface.

What is the calcium assay used for?

It is tested to diagnosis and monitor numerous conditions related to the heart, nerves, bones and kidneys.

Hypercalcemia can be the result of hyperparathyroidism (overactive parathyroid gland), cancer, carcinomas, vitamin D overdoses and are of diagnostic value in detecting chronic renal disease and acute pancreatic disease.

Hypocalcemia is associated with hypoparathyroidism (underactive parathyroid gland), vitamin D deficiency, calcium deficiency, kidney dysfunction and renal failure. For more information on risk factors for post-thyroidectomy hypocalcemia, please click here [external link].

The Randox Calcium assay is used for the quantitative in vitro determination of calcium concentration in serum, plasma and urine.
