Glycated hemoglobin analyzer reagent matching device and its working method

Abstract

The invention discloses a glycosylated hemoglobin analyzer reagent matching device as well as an operating method thereof. The device comprises reagents, IC cards and a testing instrument, wherein the reagents and the IC cards are bound in a one-to-one way. The method comprises the steps of writing in-plant initial data in the IC cards, verifying the IC cards in testing, and recording the IC cards after testing. According to the invention, the influence to testing precision of artificial factors is prevented by binding the IC cards and the reagents.

Description

technical field [0001] The invention relates to a medical testing device, in particular to a reagent matching device for a glycated hemoglobin analyzer and a working method thereof. Background technique [0002] The normal range of glycosylated hemoglobin is 4% to 6%, and the interval is narrow. The most important diagnostic range of glycosylated hemoglobin is 6% to 6.5%, and the interval is only 0.5%, which is even narrower. Internationally, the precision index CV should not exceed 5%. If it is greater than 5%, the difference between 6% and 6.5% cannot be distinguished. It can be seen that the measurement of glycosylated hemoglobin has high requirements for instruments and reagents. The applicant previously proposed a four-gradient elution analysis method for glycated hemoglobin analyzer (patent number CN201110084781.3), which can obtain reliable precision through four reagents (eluents). However, as a consumable, the eluent will have certain differences between different ...

AI Technical Summary

Problems solved by technology

However, as a consumable, the eluent will have certain differences between different batches, and certain calibration parameters are required to match the tester. Most of the existing reagent manufacturers use the method of printing the reagent parameters on the reagent label. On the label paper, and then manually input by the customer into the test instrument, manual input is prone to human error

Moreover, since the four eluents of the glycosylated hemoglobin test are open-type reagents, some users may use compatible reagents for detection in order to reduce the cost of use, which will greatly reduce the accuracy of the test and affect the life of the instrument.

In addition, the existing test instruments cannot enable users to accurately understand the consumption of reagents. When there is an error in reagent consumption, or the waste of reagents due to instrument problems, users will not be able to provide accurate data information to the manufacturer and demand compensation.

In the LPLC test process, the chromatographic column will significantly reduce the adsorption and elution capacity after a certain number of cumulative elutions, and needs to be replaced in time. A method that records the number of tests and can remind the user to replace the chromatographic column in time
