Abstract

The invention relates to an inorganic phosphorus (phosphate radical) diagnostic and measuring kit utilizing technologies of an enzymatic-colorimetric method and an enzyme-link method, also relates to a method and a principle of measuring inorganic phosphorus (phosphate radical) concentration and compositions and components of reagents, and belongs to the technical field of testing and measuring of medical science, food, and environment. The kit mainly comprises the following compositions: buffer solution, reduced coenzyme, glutamine, adenosine diphosphate, pyruvic acid, glutamine synthetase, glutamate decarboxylase, malic dehydrogenase, and stabilizer; samples are mixed with the reagents in certain volume ratio to perform a series of enzymatic reactions; then reactants are placed under a UV / visible analyzer; and the descending level of absorbance is tested at the position where dominant wave length is 340nm so as to measure and calculate the inorganic phosphorus (phosphate radical) concentration.

Description

technical field [0001] The invention relates to an inorganic phosphorus (phosphate) diagnosis / measurement kit, and at the same time, the invention also relates to a method for measuring the concentration of the inorganic phosphorus (phosphate), which belongs to the technical field of medicine / food / environmental inspection and measurement. Background technique [0002] 87% of the phosphorus in the human body exists in the bones. The phosphorus in the blood and the phosphorus in the bones maintain a dynamic balance. There is a certain relationship between the concentration of calcium and phosphorus in the blood. When the blood calcium increases in normal people, the blood phosphorus decreases, and vice versa. Of course. The product of [calcium] and [phosphorus] concentrations in plasma remains within a certain range; When the product of the two is greater than 40, calcium and phosphorus are deposited in the bone tissue in the form of bone salt, and when the product is greater...
