Problems solved by technology

[0003] At present, Sysmex's UF-5000i automatic urine analyzer adopts this method for clinical urine sample analysis. The instrument is designed with two channels and two reaction pools to distinguish nucleated components from non-nucleated components and perform flow cytometry analysis. Therefore, under this condition, the instrument must be equipped with two different dyes and two different diluents to meet the test conditions of the instrument. Therefore, the instrument needs to perform two-channel inspections, which will greatly reduce the instrument’s performance. Detection efficiency

Abstract

The invention discloses a diluent for urine visible component analysis and a preparation method. The diluent for urine visible component analysis comprises an anticoagulant, a buffer solution, an alkaline reagent, a surfactant, an osmotic pressure regulator and a bacteriostatic agent. The anticoagulant and purified water are weighed and dissolved in a corresponding container, a plurality of raw materials except the anticoagulant are weighed, and are dissolved in purified water to obtain two mixed solutions; and the two mixed solutions are mixed, the cleaning solution obtained by cleaning the container is added into a basic diluent, the pH value is adjusted by using the alkaline reagent to obtain a diluent. A suitable diluent is provided for dilution transition to ensure the integrity of visible components.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a diluent for analyzing urine formed components and a preparation method. Background technique [0002] Flow cytometry is a biological technique for the continuous analysis of multiple parameters of individual cells passing through optical or electronic detectors. Flow cytometry can analyze tens of thousands of cells at high speed, and can measure multiple parameters from one cell at the same time. It has the advantages of fast speed, high precision, and good accuracy. It is one of the most advanced cell quantitative analysis technologies in the contemporary era. In clinical testing, due to the complex contents of urine samples and their different concentrations, in order to distinguish the formed components of urine, the samples will be treated with fluorescent dyeing to ensure that the instrument can receive the fluorescent signal from the formed components.
