  • Publication number: 20110139634
    Abstract: The present invention is related to an electrochemical biosensing test strip, biosensing meter, system and method for analyte measurement incorporating a hematocrit correction. The biosensor strip comprises a first and a second electrode sets respectively for detecting analyte concentration and hematocrit level. The first and second electrode sets are respectively corresponding to different reaction zones and a reaction reagent is only formed on the first electrode set corresponding reaction zone. Applying a first signal comprising a DC component and a second signal comprising an AC component that has a constant frequency respectively to the first and second electrode sets can respectively detect an uncorrected analyte concentration and hematocrit level. Therefore, the corrected analyte concentration is more accurate by incorporating the hematocrit correction.

  • Patent number: 7316766
    Abstract: An electrochemical biosensor strip has a base, an electrode system, an optional spacer and a cover. The electrode system is laid on the base. The spacer is laid on the electrode system and exposes a portion of the electrode system for electrical connection with a meter and a different portion of the electrode system for application of a test reagent. The cover is covered on the spacer to form a cavity. Between the test reagent and the base, a hydrophilic layer is laid between them for increasing the binding effect of the test reagent on the base. The hydrophilic layer is laid on the area excluding from the electrode system and laid on the electrode system about 50% to 0% of the electrode system corresponding to the test reagent. The hydrophilic layer will not interfere with signal transmission of the electrode system so the test is more accurate.
