The invention provides a method for performing reliability evaluation on a result of a quantitative detection item of a detection
system, and a use, and relates to the technical field of
quality control of a
medical laboratory. According to the method, actual experimental samples in the laboratory are used as evaluation samples, and there is no matrix effect compared with
quality control. Representative samples are selected, that is, the experimental samples comprise an experimental sample in which a detection value of the quantitative detection item is less than a normal
reference range, an experimental sample greater than the normal
reference range, and an experimental sample within the normal
reference range. In addition, the judging criteria of the method not only consider the requirements of quality objectives in the unique analysis of the detection item of the
medical laboratory, but also consider the requirements of statistical
linear regression. Therefore, the reliability of the result of the quantitative detection item of the detection
system can be evaluated by the method in a simple and convenient, operable and efficient manner, and the method has an important practicalvalue on the
quality control of the
medical laboratory and the guarantee of the diagnosis and treatment of patients.
