Embodiment 1

[0047] Embodiment 1 The present invention's Internet-based real-time shared blood screening indoor quality control method (1)

[0048] see figure 1 , the Internet-based real-time shared blood screening indoor quality control method of the present embodiment includes the following steps:

[0049] S1. Collect the effective and under-controlled indoor quality control data of a certain commercial brand reagent in the blood bank laboratory and the corresponding reagent batch number and quality control product batch number. The data volume of each commercial brand reagent must be ≥ 200. Participate in data collection The number of laboratories must be ≥ 3.

[0050] S2, the data are grouped according to the batch number of the reagent and the batch number of the quality control substance, and the mean and the variance within the group are calculated respectively. The amount of data in each group must be ≥50.

[0051] S3, the total variance is the sum of the variances of each group...

[0080] Embodiment 2 The present invention's Internet-based real-time shared blood screening indoor quality control method (2)

[0081] see figure 2 , the Internet-based real-time shared blood screening indoor quality control method of the present embodiment includes the following steps:

[0082] S1. Collect the effective and under-controlled indoor quality control data of a certain commercial brand reagent in the blood bank laboratory and the corresponding reagent batch number and quality control product batch number. The data volume of each commercial brand reagent must be ≥ 200. The number of laboratories participating in data collection for branded reagents must be ≥3.

[0083] S2, grouping the data according to the batch number of the reagent and the batch number of the quality control substance, and calculating the mean and variance within the group of the detection values ​​of the quality control substance within the group. The amount of data in each group must be ≥50. ...

Embodiment 3

[0089] Embodiment 3 application example

[0090] From January to August 2019, 4 blood stations in Shanghai Blood Center, Shenzhen Blood Center, Shandong Blood Center and Dalian Blood Center used Roche COBAS s201 MPX v2.0 reagent to detect NRLQConnect quality control by mixed sample detection method Taking the HCV detection data of the product as an example, compare the difference between the patent of the present invention and the Australian quality control analysis software. The materials and methods are basically the same as the article "Discussion on the Application of Internet-Based Real-time Sharing Indoor Quality Control Technology in Blood Screening Nucleic Acid Detection" published by the applicant in "Chinese Journal of Blood Transfusion" Volume 32, Issue 9, 2019. The time is extended, and some laboratory data are more substantial than the original text.

[0091] S1. Collect the HCV detection data of the NRLQConnect quality control product in the Roche COBAS s201 MPX...

Abstract

The invention relates to an internet-based real-time shared blood screening indoor quality control system and method. The method comprises the following steps: collecting effective and controlled indoor quality control data of a plurality of laboratory reagents of a certain commercial brand and reagent batch numbers and quality control product batch numbers corresponding to the data; grouping thedata according to the reagent batch number and the quality control product batch number; respectively calculating the mean number and the intra-group variance of the detection values of the intra-group quality control products; calculating the total SD; calculating the composition ratio of each group of data volume in the total data; calculating the total average number according to the data volume composition ratio of each group and the respective average number of the weighted sum; setting the quality control limit of the reagent to be + / -2 times of the total average number of total SD, wherein the detection result of the quality control product is in-control within the quality control limit, otherwise, the detection result is out of control. The system and the method provided by the invention can be used for serological detection of infectious disease markers and indoor quality control of nucleic acid detection in blood screening and clinical detection, can provide more accurate judgment results, and realizes real-time online analysis and shared analysis of indoor quality control results in reagent groups.

Description

technical field [0001] The invention relates to the field of blood screening indoor quality control, in particular to an Internet-based real-time shared blood screening indoor quality control system and method. Background technique [0002] Indoor quality control (internal quality control, IQC) is to take certain methods and steps by the laboratory staff to continuously evaluate the reliability of the laboratory's work, so as to monitor the precision of the laboratory's routine work and determine whether the experimental results are Reliable, can issue a report of a job. The objects of screening for blood infectious diseases are healthy blood donors. In the absence of medical history and signs, more reliance is placed on laboratory tests, and suspected infected persons are selected from healthy blood donors based on the test results. Therefore, blood screening requires experiments. The detection results of the laboratory have higher stability and reliability. The quality c...
