Patent ID: 8306939

Claim:
A test value prediction apparatus comprising: a recording unit and an operation unit, wherein a mobility and an absorbance value corresponding to the mobility are used as a set of paired data; and electrophoresis waveform data formed by a plurality of said sets of paired data, and a prediction equation for predicting the amount of a specific substance in an analyte or the presence or absence of a disease in the living body from which the analyte was obtained are recorded in the recording unit; the prediction equation is a regression equation predetermined by a maximum likelihood estimation method, in which the explanatory variable is an absorbance value corresponding to a mobility in corrected waveform data generated as a result of the electrophoresis waveform data on a plurality of analytes being subjected to normalization and area correction, and the criterion variable is the amount of the specific substance or the presence or absence of a disease; the operation unit is configured to read the electrophoresis waveform data recorded in the recording unit, and generate corrected waveform data by performing normalization and area correction on the electrophoresis waveform data, and read the prediction equation recorded in the recording unit, calculate a value of the prediction equation by substituting the absorbance value corresponding to the mobility which is the explanatory variable of the prediction equation, with an absorbance value from the corrected waveform data generated from the electrophoresis waveform data recorded in the recording unit, and use the calculated value as a prediction value of the amount of the specific substance or the presence or absence of a disease; and the area correction is a process to correct absorbance values in electrophoresis waveform data using the area in the normalized electrophoresis waveform data and the total protein value of the analyte.
