A test sensor container for use with an analyte measuring system may include a cartridge that includes a base, two opposite sidewalls extending away from the base, and a plurality of compartments each dimensioned to hold a test sensor. At least one of the two opposite sidewalls is oriented at an acute angle relative to a reference axis that is perpendicular to the base. The test sensor container may further include at least one foil cover sealing the plurality of compartments and an ejection mechanism.

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 &#x2212;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.

Determining analyte concentration from variant concentration distribution in measurable species

Biosensor systems including a measurement device and test sensors including at least three independently addressable electrodes, with at least two of the electrodes being substantially chemically isolated are disclosed. One or more working electrodes may be combined with two or more counter electrodes. The two or more counter electrodes may operate at different potentials to provide for multi-analyte electrochemical analysis. Analysis methods are provided to perform multi-analyte electrochemical analysis and test sensors are provided having resistance to chemical mixing between secondary analysis regions.

Multi-region and potential test sensors, methods, and systems

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, &#x394;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.

Biosensor systems for determining analyte concentration based on complex index functions

Systems and methods for electrochemically oxidizing components of a test-sensor reagent prior to deposition on a test sensor comprise at least a first electrode and a second electrode for contacting the test-sensor reagent. The first electrode and the second electrode may have hollow interior portions for contacting the test-sensor reagent to produce a modified test-sensor reagent having a reduced background current.

A test sensor container () is designed for use with an analyte measuring system (). The test sensor container () may include a cartridge () including a plurality of stacked individual compartments () connected to one another in an accordion-style fashion. Each individual compartment () is collapsible from an expanded to a collapsed condition and is dimensioned to hold a test sensor () when in the expanded condition. The test sensor container further includes at least one foil cover () sealing the plurality of compartments ().

A fluid sensor comprises a formed plastic body and a reagent. The body has a top face with an integral first surface. The body also has a bottom face opposed to the first surface and a sidewall that extends from the periphery of the top face. The first surface is adapted to accept a fluid sample. The reagent is disposed on the integral first surface and causes a color change detectable on the bottom face when the reagent reacts with an analyte in the fluid sample.

Sensor and package

The present disclosure relates to packaging containers for holding a plurality of test sensors. The packaging container may include a first semi-circular housing and a second semi-circular housing. The first semi-circular housing has a plurality of first test sensor containing regions.

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.
