Abstract

The invention relates to a kit for diagnosing / mensurating inorganic phosphorus by utilizing the technologies of the enzymic colorimetric method and the enzyme linked immunosorbent assay. The invention further relates to a method, a principle and the composition and the components of a reagent for mensurating the concentration of the inorganic phosphorus, and belongs to the technology field of medical / food / environmental inspection and measurement. The main components of the kit include a buffer solution, coenzyme, inosine, 5-nucleotidase, inosine monophosphate dehydrogenase and a stabilizer. Through mixing a sample and the reagent by a certain volume ratio, a series of enzymatic reactions occur, then the reactant is placed under an ultraviolet / visible light analyzer, and the degree / velocity of the increase in absorbance at 340nm of the dominant wavelength is detected, thereby mensurating the concentration of the inorganic phosphorus.

Description

technical field [0001] The invention relates to an inorganic phosphorus diagnosis / measurement kit, and at the same time, the invention also relates to a method for measuring the concentration of inorganic phosphorus, 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; the product of calcium and phosphorus concentrations per 100 ml of plasma is about 35-40. When the product of the two is greater than 40, calcium and phosphorus are deposited in the bone ti...
