  • Analyte measurement method and system with hematocrit compensation
    Patent number: 9476088
    Abstract: Described and illustrated herein are systems and exemplary methods of operating an analyte measurement system having a meter and a test strip. In one embodiment, the method may be achieved by applying a first test voltage between a reference electrode and a second working electrode and applying a second test voltage between the reference electrode and a first working electrode; measuring a first test current, a second test current, a third test current and a fourth test current at the second working electrode after a blood sample containing an analyte is applied to the test strip; measuring a fifth test current at the first working electrode; estimating a hematocrit-corrected analyte concentration from the first, second, third, fourth and fifth test currents; and annunciating the hematocrit-corrected analyte concentration.
    Type: Grant

  • Analyte measurment method and system
    Patent number: 8545693
    Abstract: Described and illustrated herein are systems and exemplary methods of operating a multianalyte measurement system having a meter and a test strip. In one embodiment, the method may be achieved by applying a test voltage between a reference electrode and a first working electrode; measuring a first test current, a second test current and a third test current at the working electrode with the meter after a blood sample containing an analyte is applied to the test strip; estimating a hematocrit-corrected analyte concentration from the first, second and third test currents; and displaying the hematocrit-corrected analyte concentration.
