An electrochemical analytical test strip 100 for the determination of an analyte (such as glucose) in, or a characteristic (e.g., hematocrit) of, a bodily fluid sample includes an electrically-insulating base layer 110, a capillary sample-receiving chamber 170, a working electrode 124 on the base layer in the chamber, a reagent layer 130 on the base layer in the chamber and overlapping the working electrode, a counter electrode 122 devoid of the reagent layer on the base layer in the chamber and a reagent diffusion bridge 150. The reagent diffusion bridge is of predetermined dimensions and adjoins the counter electrode 122 and the reagent layer 130, thereby defining a predetermined separation distance therebetween. The working and counter electrodes are disposed on the base layer in a coplanar configuration. The magnitude and timing of an electrochemical response is measured and used to determine the analyte. |
