Patent number: 7943022Abstract: An analyte, system, strip and method are described. In one example, an analyte test strip is provided that includes a substrate, electrically conductive material and an isolated portion of the electrically conductive material. The substrate has a generally planar surface that extends from a first end to a second end. The electrically conductive material is disposed on the generally planar surface to define a plurality of electrodes spaced apart from each other. The isolated portion of the electrically conductive material is disposed between at least two electrodes so that the isolated portion is not in electrical communication with the plurality of electrodes.Type: GrantFiled: September 4, 2007Date of Patent: May 17, 2011Assignee: Lifescan, Inc.Inventors: Maria Teodorczyk, Remedios Dato, Koon-wah Leong

Patent number: 5843691Abstract: A multilayer reagent test strip measures the concentration of analyte in a liquid sample that is applied to it. The sample is guided to a number of assay areas arrayed along the strip, where the analyte can react with a reagent to cause a color change. Each assay area also includes an inhibitor for the color-change reaction. The inhibitor concentration increases in successive assay areas; thus, the number of areas that change color is a measure of the analyte concentration. The test strip is particularly adapted for measuring glucose in a whole blood sample. In a preferred embodiment, the sample is guided to the assay areas along a path formed by crushing selected areas of a membrane, and the assay areas are uncrushed areas of the membrane.Type: GrantFiled: December 31, 1996Date of Patent: December 1, 1998Assignee: Lifescan, Inc.Inventors: Joel Douglas, Ernest Kiser, Michael F.

Patent number: 5620863Abstract: A reagent strip for measuring glucose concentration in a biological fluid containing red blood cells has reduced interference of hematocrit with the glucose measurement. When a biological fluid contacts the strip, it causes, in a reagent impregnated in the strip, a color change which is a measure of the glucose concentration in the fluid. However, the color change is also affected by the red blood cell concentration (hematocrit), thereby reducing the accuracy of the glucose measurement. The hematocrit effect is reduced by adding to the reagent a component, such as imidazole or imidazole and N-acetylglucosamine, for minimizing side reactions of the glucose, or its reaction products, with the fluid.Type: GrantFiled: June 7, 1995Date of Patent: April 15, 1997Assignee: LifeScan, Inc.Inventors: Michael F.
