Measures Magnesium.Coral Clinical Systems has answered these concerns of the busy laboratory professional by engineering the “Flexipour”reagent system which comprises of individual liquid stable components, which when mixed together in recommended ratios generate a dependable liquid stable working reagent. Depending on the usage, individual reagents may be poured at one go or flexibly in smaller volumes. Magnesium, along with potassium, is a major intracellular cation. It is an activator of various enzymes. It is also involved in amino acid activation and protein synthesis. Increased levels are found in dehydration, Addison’s disease and uremia. Decreased levels are found in malabsorption, during treatment of diabetic coma, chronic renal disease, chronic alcoholism, pancreatitis and hyperthyroidism. Magnesium combines with Calmagite in an alkaline medium to form a red coloured complex. Interference of calcium and proteins is eliminated by the addition of specific chelating agents and detergents. Intensity of the colour formed is directly proportional to the amount of magnesium present in the sample.
