Abstract

An analyte test strip is provided that includes a generally planar substrate and a plurality of conductive areas disposed on the substrate to define five distinct conductive portions comprising at least five contact lands defining respective vertices of a polygon, and in which two contact lands are located in a single conductive portion. System and method utilizing the test strip are also described.

Claims

1. An analyte measurement system comprising:

a test meter with a housing, the test meter including a connector module disposed in the housing, the connector module including a plurality of spaced apart contact leads disposed in the connector module, and providing potential and/or current to the contact leads and determining analyte concentration from test strip signals; and

a test strip comprising a generally planar substrate, the test strip including a plurality of conductive areas disposed on the substrate to define five distinct conductive portions comprising at least five contact lands defining respective vertices of a regular polygon with an odd number of at least five sides, and in which two contact lands are located in a single conductive portion so that the plurality of spaced apart contact leads engage respective contact lands when the substrate is inserted into the connector module.

2. The system of claim 1, in which the regular polygon comprises a regular heptagon.

3. The system of claim 2, in which the generally planar substrate extends along a longitudinal axis to define a generally rectangular member, in which one of the vertices of the regular heptagon is located substantially on the longitudinal axis and the remainder of the vertices are symmetric about the longitudinal axis.

4. The system of claim 3, further comprising first and second working electrodes and reference electrode in electrical communication with respective conductive portions.

5. The system of claim 1, in which the connector module comprises first and second members with the plurality of contact leads located proximate the first and second members.

6. The system of claim 5, in which the plurality of contact leads comprise respective terminal ends that define vertices of the regular polygon.
