Measures Glucose concentration. 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. Glucose is the major carbohydrate present in blood. Its oxidation in the cells is the source of energy for the body. Increased levels of glucose are found in diabetes mellitus, hyperparathyroidism, pancreatitis, renal failure. Decreased levels are found in insulinoma, hypothyroidism, hypopituitarism and extensive liver disease. Glucose is oxidised to gluconic acid and hydrogen peroxide in the presence of glucose oxidase. Hydrogen peroxide further reacts with phenol and 4 – amino antipyrine by the catalytic action of peroxidase to form a red coloured quinonimine dye complex. Intensity of the colour formed is directly proportional to the amount of glucose present in the sample.
