Abstract

An electrochemical based analytical test strip for the determination of an analyte (such as glucose) in a bodily fluid sample (for example a whole blood sample) and/or a characteristic of the bodily fluid sample (for example hematocrit) includes a first sample receiving chamber with first and second sample application openings and first and second electrodes. The first and second electrodes are disposed in the first sample receiving chamber between the first and second sample application openings. The electrochemical based analytical test strip also includes a second sample receiving chamber and a plurality of electrodes disposed in the second sample receiving chamber. In addition the second sample receiving chamber intersects the first sample receiving chamber between the first and second electrodes thereby defining a chamber intersection.
