Abstract

The invention discloses a laboratory system error allowable range evaluation system based on quality control data, including: a statistical unit for performing mean value statistics based on accumulated and collected quality control data, and for formulating the allowable range of corresponding items according to relevant project regulations. A calibration unit that accepts the error standard TEa, a drawing unit that generates a horn diagram based on the statistical mean and an acceptable error standard TEa, and a computing unit that generates a corresponding graph based on the currently collected measurement data and intersects with the horn diagram to obtain an intersection point, Bounding elements used to derive new acceptable ranges for laboratory system errors from the obtained intersection points. By re-evaluating the new acceptable error linear range on top of the acceptable error standard formulated in accordance with the regulations; in the case of systematic errors, analyzing the existing data to obtain a narrower temporary acceptable total error The test results within this range can meet the total error requirements and be accepted.

Description

technical field [0001] The invention relates to the technical field of quality control, in particular to a laboratory system error tolerance range evaluation system 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 is different...
