Abstract

The invention discloses a method for evaluating the allowable range of laboratory system errors based on quality control data, which comprises the following steps: performing mean value statistics on quality control data; formulating the allowable error standard TEa of corresponding items according to relevant regulations; The error standard TEa generates the horn diagram; generates the corresponding graphics according to the currently collected quality control data and intersects with the horn diagram to obtain the intersection point; obtains the new allowable range of the laboratory system error according to the obtained intersection point; through the acceptable error standard formulated in accordance with the regulations On top of that, re-measure the new acceptable error linear range; in the presence of systematic errors, analyze the existing data to obtain a narrower temporary range of total error acceptable, and the test results in this range are Can meet the total error requirements (national or industry standards) and be 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 ...
