Embodiment 1

[0045] This embodiment relates to an electronic quality control card for a time-resolved fluorescence immunoassay analyzer, which includes a reagent shell and a quality control NC membrane. The quality control NC membrane carries two fluorescent quality control lines, which are produced through the following steps:

[0046] a. Obtain fluorescent quality control line solution;

[0047] Use 45mmol / L PB solution containing 0.01% (mass percentage) SDS to dilute the carboxyl-modified time-resolved fluorescent microspheres according to the high and low concentrations. After dilution, the fluorescent microspheres have no cross-linking and are in a single state. , to obtain a quality control line solution with high fluorescence intensity and another quality control line solution with low fluorescence intensity; wherein the time-resolved fluorescent microspheres are made of polystyrene;

[0048] b. Draw a fluorescent quality control line on the NC membrane;

[0049] Scribing and dryin...

Embodiment 2

[0069] This embodiment relates to the evaluation of the verification results of the time-resolved fluorescence immunoassay analyzer by the electronic quality control card of the present invention.

Embodiment 21

[0071] This embodiment relates to the comparison between the calibration of the electronic quality control card of the present invention and the conventional calibration of the time-resolved fluorescence immunoassay analyzer.

[0072] The electronic quality control card of the present invention verifies the time-resolved fluorescence immunoassay analyzer operation process:

[0073] When using the quality control card for the first time, the information on the matching RFID card needs to be input to the time-resolved fluorescence analyzer; the quality control card of the present invention is inserted into the analyzer, and the analyzer first recognizes the two-dimensional code on the quality control card, completes the identification and puts it on the analyzer. The parameter data of the quality control card is stored, and the analyzer automatically scans the high fluorescence value and low fluorescence quality control lines on the quality control card, and compares the scanning...

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...
