Abstract

The invention relates to a kit for diagnosing / mensurating carbon dioxide 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 carbon dioxide, and belongs to the technology field of medical / food / environmental inspection and measurement. The main components of the kit include a buffer solution, coenzyme, phosphoenolpyruvic acid, glyceraldehyde-3-phosphate, glyceraldehyde-3-phosphate dehydrogenase, phosphoenol pyruvate carboxylase and a stabilizer. Through mixing a sample and the reagent by a certain volume ratio, an enzymatic reactions occurs, 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 carbon dioxide.

Description

technical field [0001] The invention relates to a carbon dioxide diagnosis / measurement kit, and at the same time, the invention also relates to a method for measuring carbon dioxide concentration, which belongs to the technical field of medicine / food / environmental inspection and measurement. Background technique [0002] The content of carbon dioxide in the blood plays an important role in the regulation of acid-base balance in the human body. The constant blood pH is an essential condition for maintaining life activities. Among the various buffer systems in blood plasma, the bicarbonate buffer system is the most important, which directly affects the pH of blood. [0003] Changes in the content of carbon dioxide in the blood mainly reflect metabolic acid-base balance disorders. In pure metabolic acid or alkalosis, blood bicarbonate [HCO 3 - ] decreased or increased, the total carbon dioxide also decreased or increased. In simple respiratory acid or alkalosis, blood bicar...
