摘要:
The present invention provides a colorimetric method that can perform a simple and reliable analysis in a short time. An aqueous solution including a bipyridyl copper complex and glucose dehydrogenase is prepared. A filter paper is impregnated with the aqueous solution and dried. When a sample such as blood is applied to the filter paper, the bipyridyl copper complex produces reddish brown color in accordance with the glucose concentration, and the color produced in the complex is measured. This reaction is a single reaction and thus occurs in a short time (e.g., 5 seconds or less). Since this reaction requires neither hydrogen peroxide nor oxygen, the measured values are highly reliable.

The enzyme reaction of this method is a single stage reaction, and the color production reaction occurs via the mediator. Therefore, the measurement can be performed in a short time. Since this reaction requires neither hydrogen peroxide nor oxygen, the measured values are highly reliable.
