摘要： A disposable electrode strip for testing a fluid sample including a laminated strip with a first and second end, a reference electrode embedded in the laminated strip proximate to the first end, at least two working electrodes embedded in the laminated strip proximate to the first end and the reference electrode, an open path for receiving a fluid sample beginning from the first end and being sufficiently long to expose the reference electrode and the working electrodes to the fluid sample, and conductive contacts located at the second end of the laminated strip. The laminated strip has a base layer with a conductive coating, a reagent holding layer, a channel forming layer and a cover. One of the working electrodes contains a reagent substantially similar to the reagent of the reference electrode and a second working electrode contains a reagent having an enzyme.

摘要： A method of compensating for the presence of hematocrit in a blood sample when measuring a blood analyte using a disposable sensor strip. The method includes disposing a blood sample onto a working electrode and a reference electrode of the disposable sensor strip to obtain a concentration of an analyte in the blood sample, measuring a resistance value of the blood sample between the reference electrode and the working electrode, and calculating a corrected concentration of the analyte using the resistance value and a hematocrit equation to correct for the presence of hematocrit in the blood sample.
