  • Patent number: 8465978
    Abstract: Methods and devices for conducting platelet aggregation analysis. A method for conducting platelet aggregation analysis by a cartridge device, including providing a blood sample in the cartridge device, stirring the blood sample within the cartridge device, measuring the electrical impedance between electrodes to obtain measured electrical impedance values, comparing measured electrical impedance values, discarding and repeating the measurements of the electrical impedance in case a variation of the measurements is outside a predetermined threshold range, or reporting the measured electrical impedance values in case the variation of the measurements is within the predetermined threshold range. Reported measured electrical impedance values indicate platelet aggregation in a blood sample.
