Embodiment Construction
[0011] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.
[0012] Such as figure 1 As shown, a system for evaluating the allowable range of laboratory system error based on quality control data, the system for evaluating the allowable range of laboratory system error based on quality control data includes: a system for performing mean value statistics based on accumulated quality control data The statistical unit 1 is used to formulate the acceptable error standard Tea of the corresponding pro...

The invention discloses a system for evaluating the allowable error range of a laboratory system based on quality control data. The system comprises a statistical unit which is used for making statistics of the mean according to accumulated collected quality control data, a calibration unit which is used for setting an acceptable error standard TE of a corresponding item according to the relevant regulations of the item, a drawing unit which is used for generating a horn graph according to the statistical mean and the acceptable error standard TE, an operation unit which is used for generating a corresponding graph according to currently collected measurement data and making the graph intersect with the horn graph to obtain an intersection point, and a range limiting unit which is used for getting a new acceptable 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 withinthe range can meet 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, and 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 acquisition method is: on the premise that there is no systematic error, the difference between the detection data and the real data in a certain detection range (the difference is the random error or the detection limit of the detection method) within the acceptable total error range Inside. However, the actual situation is that systematic errors are permanent. There must be an error at each different concentration point in the entire linear range, and the error size is different. This kind of e...
