An analytical test strip for the determination of an analyte such as glucose in, or a characteristic of, a bodily fluid sample includes an electrically-insulating base layer 110, a first patterned spacer layer 120 disposed on the electrically-insulating base layer, a second patterned spacer layer 130 disposed on the first patterned spacer layer; and a top hydrophilic layer 140 disposed on the second patterned spacer layer. In addition, the electrically-insulating base layer, the first and second patterned spacer layers and the top hydrophilic layer define a tiered capillary chamber that has a first tiered capillary chamber portion 154 defined in the first patterned spacer layer and a second tiered capillary chamber portion 156 defined in the second patterned spacer layer. Moreover, the first and the second tiered capillary chamber portions are in direct fluidic communication with one another. The chamber portions may each have a predetermined and different hydrophilicity. |
