Abstract

The invention relates to enzyme method measuring sodium ion content method and its diagnosis kit. It is adopted galactosidase reaction colorimetry to use sodium ion to activate beta-galactosidase enzymolysis o-nitrophenol group-beta-D- pyranoside galactose to make 405nm dominant wavelength absorbance rise. Its absorbance amplitude of fluctuation is proportional to sample sodium ion. The method has high specificity, good accuracy. The diagnosis kit can be made into bi-agent to reduce cross influence. The method can be quickly measured by ultraviolet / visible light analyzer or semi / full automatic biochemical analysis. Its measuring cost is low; and it is convenient for generalization and application.

Description

Technical field

[0001] The invention relates to a method for enzymatically measuring the sodium ion content in serum, plasma and other samples, and a sodium ion diagnostic kit prepared by applying the method, and belongs to the technical field of medical testing and measurement. Background technique

[0002] The sodium ion content in serum (referred to as "blood sodium") is of very important clinical significance. There are three determination levels in medicine, in order: level 1-115mmol / l, level 2-135mmol / l, level 3- —150mmol / l. When the patient's blood sodium concentration is equal to or lower than level 1, symptoms such as confusion, fatigue, nausea, headache, vomiting, and anorexia may occur, indicating that the proportion of water in the body is greater than sodium, and corresponding treatment measures should be taken; when the blood sodium concentration When the serum sodium concentration is lower than level 2, the cause of hyponatremia should be found, and serum osm...
