Abstract

The invention relates to a kalium diagnosis/determination kit which uses the techniques of an enzyme circulation amplification method, an enzyme colorimetry method and an enzyme-linked method; simultaneously, the invention also relates to a method principle used for determining kalium consistency, reagent composition and component, belonging to the field of medical/food/environment detection determination technique. The main compositions of the kit of the invention comprise buffer solution, reduction-typed coenzyme, adenosine diphosphate, phosphoenolpyruvate, ammonium ion, pyruvate kinase, alanine dehydrogenase, glycine oxidase, and stabilizer; samples and reagents are mixed according to a certain volume proportion so as to generate a series of enzymatic reactions; subsequently, reaction matters are arranged under an ultraviolet/visible light analyser so as to detect the degree/speed of the absorbency reduction of the main wavelength at the 340nm position, thus calculating the consistency of the kalium.

Description

technical field [0001] The invention relates to a potassium diagnosis / measurement kit, and meanwhile, the invention also relates to a method for measuring potassium concentration, which belongs to the technical field of medicine / food / environmental inspection and determination. Background technique [0002] Clinical significance of three decisive levels of serum potassium: below the lower limit of the reference value, showing hypokalemia due to renal tubular disease, hyperaldosteronism, hyperinsulinism, metabolic alkalosis, diuretic therapy, insulin therapy for diabetes During ketosis, potassium ions are transferred into cells, etc. If it is higher than the upper limit of the reference value, it may be caused by glomerular disease, renal insufficiency, diabetic ketosis, adrenal cortical insufficiency, etc. When the serum potassium is as high as 7.5mmol / L or above, the patient will experience arrhythmia, and appropriate treatment should be considered. When serum potassium ex...
