Quality control material and calibrator for calibrating blood cell analyzers and preparation method thereof

Abstract

A quality control material and a calibrator for calibrating blood cell analyzers comprise simian whole blood plasma, anticoagulant, preservation solution, cell mimics and stabilizer, wherein the weight ratio of the simian whole blood plasma to the anticoagulant is 10:1, the weight ratio of the mixture of the simian whole blood plasma and the anticoagulant to the preservation solution is 10:1, 1 percent by weight of stabilizer is added into the mixture of the three components, and the cell mimics are added according to the amount and concentration of products. The prices of the quality control material and the calibrator are reasonable, the quality of the quality control material and the calibrator is reliable, and the quality control material and the calibrator meet national sanitary requirement, and also can more accurately test the precision and stability of a blood cell analyzer.

Description

【Technical field】 [0001] The invention relates to a quality control product and a calibrator used for checking the accuracy and stability of a cell analyzer. 【Background technique】 [0002] The hematology analyzer is an indispensable screening device in daily inspections. It shoulders a large number of screening tasks for normal or abnormal specimens every day. Once an abnormality is found, the medical staff will immediately carry out the next step of relevant inspections to make judgments based on pathological data and related treatment or conditioning. Timely divert patients and healthy personnel, reduce medical workload and speed up medical work efficiency. [0003] Because blood cell analyzers analyze and report data on a large number of patients or normal physical examination samples every day, hospitals must determine whether the performance of the instrument meets the performance indicators at the factory every day, which requires specific reference materials. At pr...

Problems solved by technology

[0004] Usually, the standard substances used in this instrument are sold by the instrument manufacturer, which gradually forms a monopoly. If the user does not use the matching reagents provided by the manufacturer but the domestically produced matching reagents, it is basically impossible for the user to buy their expensive standard substances. , while the prices of reagents supplied by manufacturers are often relatively high, resulting in the current high domestic medical costs

Furthermore, imported standard materials are often out of stock due to various restrictions, such as supply (manufacturers are also controlled), validity period (usually only three months, and less than two months to users), transportation method, and cycle time (Import basically takes more than a week), weather (must be stored at 2-8°C),
