Problems solved by technology

[0005] However, if the measurement accuracy is to be strictly controlled, it is necessary to perform operations such as measurement and replacement of the sample for each assembly, and accordingly a lot of time and man-hours are spent on calibration operations.
As a result, there is a problem that the manufacturing cost of the device increases
In addition, in addition to this, the constancy of the sample must always be guaranteed, which is not preferable from a management point of view

Abstract

The present invention relates to a calibration method, device and program, and a body fluid component measurement device calibrated using the method. Estimation of the reference detection value in each sample (26s) when the reference light source (50s) is used respectively, and when a single light source (50r) of the same type as the reference light source (50s) is used and incorporated into the device to be calibrated (10c) single detection value. Based on the reference detection value estimated for each sample (26s) and the relationship of each group of individual detection values, the detection in the test paper (26) obtained by assembling the calibration object device (10c) with a single light source (50r) is determined. Values ​​are converted into calibration curves of detection values ​​when using a reference light source (50s).

Description

technical field [0001] The present invention relates to a calibration method for calibrating a body fluid component measuring device for measuring a component in a body fluid based on a detection value related to reflected light projected onto a test paper containing a chromogenic reagent that reacts with the component in the body fluid, The device uses the program, and a body fluid component measuring device calibrated using the method. Background technique [0002] A blood glucose meter capable of measuring a subject's blood sugar level is known as one form of a body fluid component measuring device that measures a component in a body fluid. For example, an optical blood glucose meter is configured to supply blood to a test paper impregnated with a reagent that develops color according to the amount of glucose in the blood, optically detect the properties of the test paper, and calculate a blood sugar level.
