  • Patent number: 11953421
    Abstract: The analysis method includes a step of measuring cytometry parameters for each biological cell contained in a biological sample; a step of determining, for each biological cell of the biological sample, a point in a N-dimensional space whose coordinates are defined depending on the cytometry parameters measured for the corresponding biological cell, where N is an integer greater than or equal to 3; a step of automatic clustering of the points into different cell clusters depending on the measured cytometry parameters, so as to define a sample cluster file; and a step of comparing the sample cluster files with reference cluster files, each of the reference cluster files being defined from cytometry parameters of a respective pathological or abnormal biological sample.

  • Patent number: 10605801
    Abstract: This determination method comprises the steps consisting of providing a reaction vessel (2) containing a blood sample (33) and a ferromagnetic ball (11) placed on a raceway (9) provided in the bottom of the reaction vessel (2), subjecting the ball (11) to a magnetic field so as to move the ball along the raceway (9) in an oscillatory motion, exposing the blood sample to an incident light beam (36), detecting a light beam (38) transmitted through the reaction vessel (2) and coming from the incident light beam (36) in such a way as to provide a measurement signal, carrying out a first processing of the measurement signal in such a way as to provide a first signal representative of the variation of at least one physical quantity representative of the movement of the ball (11), carrying out a second processing of the measurement signal in such a way as to provide a second signal representative of the variation of at least one optical property of the blood sample, determining a first value of the coagulation time

  • Patent number: 10036762
    Abstract: A method of determining the position of at least one fixed cartography token (10) of an automaton, the token (10) including a base (11) having a lateral surface and an end face (14a), a stud (15) of smaller cross section than the base (11) projecting from the end face (14a) of the base (11), the stud (15) including an end face (16) opposite the base (11). The method is aimed in particular at deducing the coordinates (XO, YO, ZO) of at least one point (O) of the cartography token (10) with respect to a movable member.

  • Patent number: 9081024
    Abstract: The invention concerns a method for assaying soluble fibrin in a sample, in which said sample is brought into the presence of a plasminogen activator with a high specificity for soluble fibrin (PA-Fb sp) and the soluble fibrin count in the sample is measured by measuring the difference between the count of fibrin degradation products obtained after degrading soluble fibrin with PA-Fb sp and the base count of fibrin degradation products determined before bringing the sample into the presence of PA-Fb sp.
