  • Conductivity measurement cell
    Patent number: 9689821
    Abstract: The application relates to a conductivity measurement cell for measuring the concentration of a preselected biomarker or analyte in a body fluid, such as urine. In order to reduce the effect of sample dilution on measured concentration, the measured concentration can be normalized by a dilution factor, which can be determined from electrical conductivity. A test strip and measurement apparatus is disclosed for performing such normalized concentration measurement.
    Type: Grant

    Date of Patent: June 27, 2017
    Assignee: SPD Swiss Precision Diagnostics GMBH
    Inventors: Jonathan D. Barnard, Stephen J. Carlisle, Malcolm R. Jones
  • CONDUCTIVITY MEASUREMENT CELL
    Publication number: 20110291670
    Abstract: The application relates to a conductivity measurement cell for measuring the concentration of a preselected biomarker or analyte in a body fluid, such as urine. In order to reduce the effect of sample dilution on measured concentration, the measured concentration can be normalised by a dilution factor, which can be determined from electrical conductivity. A test strip and measurement apparatus is disclosed for performing such normalised concentration measurement.
