Title:
METHOD OF MEASURING GLUCOSE CONCENTRATION AND GLUCOSE CONCENTRATION MEASURING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2005/027746
Kind Code:
A1
Abstract:
Glucose concentration is determined by causing given infrared light to be incident on a sample, measuring the intensities of light having been reflected in the interior of the sample and light having passed through the sample and carrying out arithmetical operation of the measured light intensities. In the arithmetical operation, the first intensity being the intensity of light corresponding to the concentration of glucose as a target substance in the sample and the second intensity being the intensity of light corresponding to the concentration of protein as an interfering substance in the sample are computed. Not only is the first intensity corrected on the basis of the second intensity with the use of given correction formula but also the corrected first intensity is converted to a glucose concentration with the use of given working formula.
