Abstract

The invention discloses a method for evaluating the allowable error range of a laboratory system based on quality control data, including the following steps: making statistics of the mean of qualitycontrol data; setting the allowable error standard TE of a corresponding item according to the relevant regulations; generating a horn graph according to the statistical mean and the acceptable error standard TE; generating a corresponding graph according to currently collected quality control data, and making the graph intersect with the horn graph to obtain an intersection point; and getting a new allowable range of system error of the laboratory according to the intersection point. A new acceptable error linear range is determined based on the acceptable error standard set according to the regulations. Under the condition that there is system error, the existing data is analyzed to obtain a narrower acceptable temporary range of total error. A detection result within the range canmeet the total error requirement (national or industry standard), and is accepted.

Description

technical field [0001] The invention relates to the technical field of quality control, in particular to a method for evaluating the allowable range of laboratory system errors based on quality control data. Background technique [0002] Quality control, hereinafter referred to as quality control; in routine quantitative testing in clinical laboratories, the testing data presents first-order linearity within a certain range. This range has also been acquired in daily work. The essence of the obtained method is: under the premise of no systematic error, the difference between the detected data and the real data within a certain detection range (causing the difference is random error or the detection limit of the detection method) is within the acceptable total error range Inside. However, the actual situation is that systematic errors exist forever. At each different concentration point within the entire linear range, there must be an error, and the magnitude of the error ...
