| Calcium plays an essential role in many cell functions intracellularly in muscle contraction and glycogen metabolism, extracellularly, in bone mineralization, in blood coagulation and in transmission of nerve impulses. Calcium is present in plasma in three forms free, bound to proteins or complex with anions as phosphates, citrate and bicarbonate. Calcium measurements also help in monitoring of calcium supplementation mainly in the prevention of Osteoporosis. Principle Calcium with Arsenazo III at neutral pH yields a blue coloured complex, whose intensity is proportional to the Calcium concentration in the sample. Interference by Magnesium is eliminated by addition of 8 hydroxy quinoline5-sulphonic acid. |
