Abstract

An electrochemical biosensor test strip (1) that has a minimum volume blood sample requirement of about 9 microliters. The test strip has working (4) and counter (5) electrodes that are substantially the same size and made of the same electrically conducting material placed on a first insulating substrate (2). Overlaying the electrodes is a second insulating substrate (3), which includes a cutout portion (8) that forms a reagent well. The cutout portion exposes a smaller area of the counter electrode than the working electrode. A reagent for analysis of an analyte substantially covers the exposed areas of working and counter electrodes in the reagent well. Overlaying the reagent well and affixed to the second insulating substrate is a spreading mesh (13) that is impregnated with a surfactant. The small cutout portion of 4 millimeters by 4.2 millimeters, small mesh of 6 millimeters by 5.8 millimeters, and small amount of reagent, 4 microliters before drying, allow the test strip to analyze a whole blood sample of about 9 microliters.
