An analytical test strip for the determination of an analyte (such as glucose and/or hematocrit) in a bodily fluid sample (such as a whole blood sample) includes a first capillary sample-receiving chamber, a second capillary sample-receiving chamber, and a physical barrier island disposed between the first and second capillary sample-receiving chambers. Moreover, the physical island barrier is disposed such that bodily fluid sample flow between the first capillary sample-receiving chamber and the second capillary sample-receiving chamber is prevented during use of the analytical test strip.

Analyte test strip design

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 (e.g., hematocrit) includes a sample-entry chamber with a sample-application opening disposed on an end edge of the electrochemical-based analytical test strip, and first and second sample-determination chambers, each in direct fluidic communication with the sample-entry chamber. The electrochemical-based analytical test strip also includes first and second electrodes (such as first and second hematocrit electrodes) disposed in the first sample-determination chamber, and a third and fourth electrodes (for example working and reference electrodes) disposed in the second sample-determination chamber. Moreover, the first and second sample-determination chambers intersect the sample-entry chamber perpendicular (or nearly perpendicular) to one another and the first sample-determination chamber also intersects the sample-entry chamber in an aligned manner.

Various embodiments for methods and systems that allow for detecting of a direction in which a sample is flowing towards a plurality of electrodes and detecting a fill error of an electrochemical test strip.

Methods and systems to determine fill direction and fill error in analyte measurements

An electrochemical-based analytical test strip for the determination of an analyte (e.g., glucose) in a bodily fluid sample (such as a whole blood sample) includes an electrically insulating base layer and a patterned conductor layer (for example, a gold patterned conductor layer) disposed over the electrically-insulating layer. The patterned conductor layer includes at least one electrode with the electrode having electrochemically inert areas and an electrochemically active area(s). Moreover, the electrochemically inert areas and electrochemically active area(s) are of a predetermined size and a predetermined distribution such that electrochemical response of the electrode during use of the electrochemical-based analytical test strip is essentially equivalent to a predetermined electrochemical response.

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.
