Electrochemical-based analytical test strip with intersecting sample-receiving chambers
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.
1. An electrochemical-based analytical test strip for the determination of an analyte in a bodily fluid sample, the electrochemical-based analytical test strip comprising:
a first sample-receiving chamber with:
a first sample-application opening; and
a second sample-application opening;
a first electrode disposed in the first sample-receiving chamber between the first sample-application opening and the second sample-application opening;
a second electrode disposed in the first sample-receiving chamber between the first sample-application opening and the second sample-application opening;
a second sample-receiving chamber that intersects the first sample-receiving chamber between the first electrode and the second electrode, thereby defining a chamber intersection, and
at least a third electrode disposed in the second sample-receiving chamber, including a first working electrode, a second working electrode and a counter/reference electrode.
2. The electrochemical-based analytical test strip of claim 1 wherein the first working electrode, a second working electrode and a counter/reference electrode are configured for the determination of an analyte of a bodily fluid sample in the second sample-receiving chamber.
