  • Publication number: 20150176054
    Abstract: A biosensor system determines an analyte concentration of a biological sample using an electrochemical process without Cottrell decay. The biosensor system generates an output signal having a transient decay, where the output signal is not inversely proportional to the square root of the time. The transient decay is greater or less than the ?0.5 decay constant of a Cottrell decay. The transient decay may result from a relatively short incubation period, relatively small sample reservoir volumes, relatively small distances between electrode surfaces and the lid of the sensor strip, and/or relatively short excitations in relation to the average initial thickness of the reagent layer. The biosensor system determines the analyte concentration from the output signal having a transient decay.

  • Publication number: 20150098866
    Abstract: An optic light guide test sensor comprises a light guide, a reagent-coated membrane, and a mesh layer. The reagent-coated membrane and the mesh layer are attached to the light guide at an output end of the light guide. The light guide test sensor is adapted to be used to test the level of an analyte in a biological fluid sample when used with a readhead. A method of manufacturing the light guide test sensor involves providing a plurality of light guides, providing a strip of reagent-coated membrane, and providing a strip of mesh layer. The reagent-coated membrane and mesh layer are attached to the light guides by ultrasonic welding. The reagent-coated membrane and mesh layer may also be attached to the light guides by adhesive.

  • Publication number: 20150083613
    Abstract: The present invention relates to an electrochemical biosensor with improved hematocrit measurement accuracy for measuring blood glucose. According to the present invention, an electrochemical biosensor including a first electrode part for correcting a measured hematocrit value and a second electrode part for measuring a glucose concentration is effective in improving accuracy of a measured hematocrit value and in more improving accuracy of a measured blood glucose concentration using the measured hematocrit values for correction, because an insulation cover is made thinner than a working electrode and an auxiliary electrode, so that areas of a first working electrode and a first auxiliary electrode of the first electrode part exposed to a blood sample become equal; a distance between the first working electrode and the second working electrode becomes constant; and electrode areas are maintained constantly by the insulation cover even when a positioning error occurs during printing.

  • Publication number: 20150008142
    Abstract: This invention discloses a reagent composition for a biosensor having high sensitivity which is capable of improving analysis linearity of an analyte such as glucose by reacting an oxidoreductase, a metal-containing complex, and Naphthol Green B, and minimizing blood necessary for measuring blood glucose since it is possible to detect a concentration of a small amount of the analyte, and a biosensor having the same. The reagent composition for a biosensor includes at least two kinds of electron transfer mediators including Naphthol Green B, and an enzyme.

  • Publication number: 20140209460
    Abstract: A biosensor system determines analyte concentration from an output signal generated from a light-identifiable species or a redox reaction of the analyte. The biosensor system adjusts a correlation for determining analyte concentrations from output signals or determined analyte concentrations with one or more complex index function extracted from the output signals or from other sources. The complex index functions determine at least one slope deviation value, ?S, or normalized slope deviation from one or more error parameters. The slope-adjusted correlation between analyte concentrations and output signals may be used to determine analyte concentrations having improved accuracy and/or precision from output signals including components attributable to bias.
