Embodiment 1

[0157] In this example 1, skipped Figure 6 The shown steps (S603 to S609) related to the initial screening directly perform curve fitting on the original data set. in, Figure 7 It is a schematic diagram of the raw data collection obtained by executing step S601 in Embodiment 1 of the present invention. Figure 8 To skip the initial screening, proceed directly to the Figure 7 Schematic diagram of the fitting results of curve fitting on the raw data set shown.

[0158] Such as Figure 7 and Figure 8 As shown, in Example 1, there are relatively many abnormal points that do not conform to the reaction trend, and the fitting curve mistakenly identifies many abnormal points that do not conform to the reaction law as normal points, resulting in the fitted curve not being able to reflect the correct reaction law , the calibration results are not ideal.

Embodiment 2

[0160] In this embodiment 2, also with Figure 7 Based on the raw data set shown, perform Figure 6 The primary screening steps (S603 to S609) and the secondary screening steps are shown to obtain the final fitting curve and corrected data set. in, Figure 9 Schematic diagram of the initial screening steps.

[0161] Such as Figure 9 As shown, through the straight line fitting method of the initial screening, it can be effectively identified Figure 7 Most of the abnormal points do not conform to the reaction law. The method of deleting these identified abnormal points and then performing curve fitting can well avoid the problem of mistakenly identifying abnormal points as normal points during curve fitting.

Embodiment 3

[0163] In this embodiment 3, execute Figure 6 In the data correction method shown, the original data set is screened and eliminated to obtain an accurate response curve and exclude interference factors.

[0164] in, Figure 10 It is a schematic diagram of the raw data collection obtained by executing step S601 in Embodiment 3 of the present invention. Figure 11 for initial screening Figure 10 Schematic diagram of the fitting results for the raw data set shown. Figure 12 A schematic diagram of the fitting results of the secondary screening.

[0165] Such as Figure 11 As shown, the initial screening first identified Figure 10 Most of the outliers in the original data set and deleted. Such as Figure 12 shown in Figure 11 On the basis of the fitting results, through the fitting curve with stronger fitting ability, it can provide a more accurate response curve that is more in line with the reaction trend.

[0166] From the comparison of Example 1 and Example 2, it ...

Abstract

Embodiments of the present invention relate to a calibration data correction method and electronic equipment thereof. The calibration data correction method includes: receiving an original data set composed of several reaction data; performing primary screening on the original data set through linear fitting to obtain a preliminary screening data set; performing secondary screening on the primary screening data set through nonlinear fitting. After the second screening, the corrected data set is obtained. This method sequentially performs coarse screening and fine screening on the original reaction curve data set, and uses two fitting methods to iteratively remove and eliminate abnormal data that do not conform to the reaction trend and normal reaction law, ensuring the accuracy of the final calibration results.

Description

【Technical field】 [0001] The invention relates to the technical field of data screening, in particular to a calibration data correction method and electronic equipment thereof. 【Background technique】 [0002] Nephelometric assay is a very widely used antigen / antibody quantitative assay. It utilizes that during the specific time period of the antigen-antibody reaction (that is, the combination between the sample antigen / antibody and the reagent antibody / antigen added in the cuvette to form a specific conjugate), the reaction speed is directly proportional to the concentration of the analyte , The increase or decrease of the scattered light intensity (absorbance) during this period of time is proportional to the concentration of the analyte, and the quantitative determination of the antigen / antibody is realized. [0003] Taking the measurement of scattered light intensity as an example, a light source can be used to irradiate the cuvette, and the scattered light intensity of ...
