Electronic quality control card used for time-resolved fluorescent immunoassay instrument and electronic quality control card component

Abstract

The present invention discloses an electronic quality control card used for a time-resolved fluorescent immunoassay instrument. Two fluorescent quality control lines are creatively disposed on an NC membrane of a same quality control card, and the electronic quality control card is obtained through processing of particular confining liquid. According to the obtained electronic quality control card, a detection low value and a detection high value of the time-resolved fluorescent immunoassay instrument can be simultaneously checked through a single-step quality control operation, so that an error caused by two conventional check operations is eliminated, and a check process is simplified. The electronic quality control card in the present invention has relatively high check accuracy and a relatively long service life, is not liable to fluorescence decay caused by external environment effects, and can generate significant economic benefits and application value.

Description

technical field [0001] The invention relates to the technical field of quality control cards, in particular to an electronic quality control card for a time-resolved fluorescence immunoassay analyzer and an electronic quality control card component. Background technique [0002] Time-resolved fluorescence analyzer is an instrument that uses time-resolved fluorescence analysis (TRFIA) to quantitatively analyze various immune detection items in human blood and other body fluids. It is suitable for infectious disease inspection, endocrinology inspection, cytology inspection, A variety of laboratory medicine such as oncology examination has more and more application space. The use of time-resolved fluorescence immunoassay analyzers requires regular quality control to check the function of the optical system and the analysis and processing system to ensure that the performance of the instrument is within an acceptable range and to verify the validity of the operating results of t...

AI Technical Summary

Problems solved by technology

At present, the time-resolved fluorescent microspheres are usually diluted to a certain concentration and streaked onto the NC membrane, and then the NC membrane is assembled into the shell of the reagent plate, which is used as the electronic quality control card of the time-resolved fluorescence immunoassay analyzer, but due to the time-resolved Fluorescent microspheres generally have shortcomings such as sensitivity to humidity and temperature, sensitivity to light, and photobleaching, which cause the problem of obvious fluorescence intensity attenuation in the electronic quality control card during storage, which directly affects the use and test results, and is not conducive to storage.

In addition, in the process of calibrating the analyzer, it is generally necessary to carry out low-value quality control and high-value quality control successively, and there are certain quality control errors.
