ABSTRACT:
In an apparatus and method for detecting the concentration of a substance in a fluid, such as the concentration of sugar in blood, the measuring field of a test strip to which the fluid to be tested in applied is divided into two separate measuring areas. The change in the light reflection or light transmission capacity of the two measuring areas is then detected separately at repetitive time intervals, and in comparing the changes in light reflectivity or light transmission of the two measuring areas over time, perceived differences in the changes occurring in the two areas are evaluated to provide useful information.
