  • System and method for analyte measurement
    Patent number: 7338639
    Abstract: A method of measuring an analyte in a biological fluid comprises applying an excitation signal having a DC component and an AC component. The AC and DC responses are measured; a corrected DC response is determined using the AC response; and a concentration of the analyte is determined based upon the corrected DC response. Other methods and devices are disclosed.

  • Method for determining the concentration of an analyte in a liquid sample using small volume samples and fast test times
    Patent number: 7276147
    Abstract: Analytes in a liquid sample are determined by methods utilizing sample volumes of less than about 1.5 ?l and test times within ten seconds. The methods are preferably performed using small test strips including a sample receiving chamber filled with the sample by capillary action.
