    摘要: An electrochemical-based analytical test strip for the determination of an analyte (such as glucose) in a bodily fluid sample (e.g., a whole blood sample) includes a substrate, at least one working electrode disposed on the substrate, a sample-soluble enzymatic reagent layer disposed above the working electrode, a diffusion-controlling layer (DCL) disposed between the at least one working electrode and the sample-soluble enzymatic reagent layer; and a sample-receiving chamber. In addition, the sample-soluble enzymatic reagent layer is configured and constituted for operable solubility in a bodily fluid sample applied to the electrochemical-based analytical test strip and received in the sample-receiving chamber and for electrochemical enzymatic reaction with an analyte in the bodily fluid sample. Moreover, the DCL is configured and constituted to provide a predetermined diffusion rate for a component (for example a mediator) of the electrochemical enzymatic reaction through the DCL that is less than the diffusion rate of the component through the bodily fluid sample and for operable hydration by the bodily fluid sample. A method for determining an analyte in a bodily fluid sample includes applying a bodily fluid sample to an electrochemical-based analytical test strip that includes a substrate, at least one working electrode disposed on the substrate, a sample-soluble enzymatic reagent layer disposed above the working electrode, a DCL disposed between the at least one working electrode and the sample-soluble enzymatic reagent layer; and a sample-receiving chamber defined in the electrochemical-based analytical test strip.

    摘要: An analytical test strip (“ATT”) for use with a test meter includes a first insulating layer, with a first insulating layer upper surface, and a first electrically conductive layer (“ECL”) disposed thereon. The first ECL includes a first electrode portion (“EP”) and an electrical contact pad in electrical communication with the first EP. The ATT also includes a patterned spacer layer disposed above the first ECL that includes (i) a distal portion defining a bodily fluid sample-receiving chamber therein that overlies the first EP and (ii) an insulating proximal portion with an upper surface having a second ECL disposed thereon. The second ECL includes an interlayer contact portion and an electrical contact pad. A third ECL of the ATT includes a second EP and a proximal portion that overlies the interlayer contact portion. The second EP is disposed overlying and exposed to the sample-receiving chamber in an opposing relationship to the first EP.

    摘要: 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.

    摘要: 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.
