Title (EN) A CONDUCTIVITY MEASUREMENT CELL
(FR) CELLULE DE MESURE DE LA CONDUCTIVITÉ
Abstract:
(EN) 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.
(FR) La présente demande de brevet concerne une cellule de mesure de la conductivité permettant la mesure de la concentration en un biomarqueur ou en un analyte présélectionné dans un liquide organique, tel que l'urine. Pour réduire l'effet de la dilution de l'échantillon sur la concentration mesurée, la concentration mesurée peut être normalisée au moyen d'un facteur de dilution, qui peut être déterminé à partir de la conductivité électrique. L'invention concerne une bandelette réactive et un appareil de mesure permettant la mise en œuvre de ladite mesure de la concentration normalisée.
