Patent ID: 7862696

Claim:
An electrochemical sensor strip for detecting an analyte, comprising: a base; a first electrode on the base having at least one first layer on a first conductor, the first layer including a reagent layer comprising at most 8 Î¼g/mm 2 of a mediator, and an enzyme system at a deposition density of at most 0.8 Î¼g/mm 2 ; a second electrode on the base; a lid on the base; and where the strip provides a determined concentration value having at least one of a stability bias of less than Â±10% after storage at 50Â° C. for 2 weeks when compared to a comparison strip stored at âˆ’20Â° C. for 2 weeks, a hematocrit bias of less than Â±10% for whole blood samples including from 20 to 60% hematocrit, and an intercept to slope ratio of at most 20 mg/dL.
