Embodiment 1

[0134] When the current abnormal situation is that there is an abnormal point or an abnormal section in the current test section, the abnormal judgment point or the abnormal judgment section is eliminated, and the test is performed according to the original data of the remaining sections on the reaction curve. The properties of samples are predicted and reference results are generated.

[0135] The way to generate reference results can be set by default inside the instrument or by the user. For example, set the lower limit of the current judgment section Q1, the upper limit of the current judgment section Q2, the judgment wavelength is set to A, and the maximum deviation index is set. S1, check [Eliminate Abnormal Judgment Interval]. This setting means to calculate the relative deviation of each absorbance point for wavelength A in the interval [Q1, Q2]. If the absolute value of the relative deviation of a certain absorbance point exceeds the maximum deviation index S1, the ab...

Embodiment 2

[0137] When it is determined that the response curve is abnormal, changing the current test section to a preset prediction section or a prediction section input by the user, predicting the characteristics of the sample to be tested according to the original data of the prediction section, Generate reference results. The prediction section can be the default prediction section of the system, or it can be a preset setting or a section input by the user from the human-computer interaction interface. In this case, the standard calibration curve needs to be changed to another calibration curve corresponding to the prediction section. Other calibration curves can be collected in advance. The test section is an interval section used to calculate the sample test results, and the test section may be the same as the judgment section or different from the test section.

[0138] The calibration curve is a curve that characterizes the sample reactivity and the concentration relationship g...

Embodiment 3

[0140] When it is determined that the reaction curve is abnormal, the wavelength corresponding to the current test section is changed to a preset predicted wavelength or a predicted wavelength input by the user, and the characteristics of the sample to be tested are predicted according to the raw data corresponding to the predicted wavelength , generating reference results. The predicted wavelength can be the default predicted wavelength of the system, or a preset wavelength or a wavelength input by the user from the human-computer interface. In this case, the standard calibration curve needs to be changed to other calibration curves corresponding to the predicted wavelength. Other calibration curves can be pre-collected.

[0141] Specifically, when calibrator is used to calibrate the system under test, existing products only use preset reaction time, blank time, and judgment wavelength for testing, and obtain a standard calibration curve. However, for the response curve of t...

Abstract

The invention discloses a method for treating the abnormity of a reaction curve. The method comprises: according to original data, collected by a detector, of a to-be-measured sample, generating a reaction curve; extracting a characteristic variable from the reaction curve; when the characteristic variable meets the preset judging condition that the abnormity is triggered, judging that abnormity exists in the corresponding reaction curve; when it is judged that the abnormity exists in the corresponding reaction curve, treating the abnormal condition through a treatment strategy corresponding to the abnormal condition to generate a reference result; and sending the obtained reference result to a display terminal to display the reaction curve and reference result. According to the method, the phenomenon that abnormity existing in the reaction curve results in misjudgement is prevented, and corresponding reference results are provided, aiming at different abnormal conditions. Waste of test reagents and time is avoided, and the test efficiency is improved. Further, the application further provides an apparatus used for treating abnormity of a reaction curve and having the technical effect above, a biochemical analyzer, and a readable storage medium.

Description

technical field [0001] The invention relates to the technical field of biochemical analysis, in particular to a method and device for abnormal response curve processing, a biochemical analyzer and a readable storage medium. Background technique [0002] A biochemical analyzer is an instrument that uses the principle of photoelectric colorimetry to measure a specific chemical composition in body fluids, such as serum, plasma, urine, etc. Due to its fast measurement speed and high accuracy, it has been widely used in hospitals at all levels, epidemic prevention stations, and family planning service stations. In order to test the concentration of chemical components, the biochemical analyzer adds a sample to a specified reagent and measures the absorbance value of the reagent at a specified wavelength in real time to obtain a response curve during the entire test process. The concentration of the sample to be tested is calculated by extracting the range of change or rate of ch...
