This determination method comprises the steps consisting of providing a reaction vessel () containing a blood sample () and a ferromagnetic ball () placed on a raceway () provided in the bottom of the reaction vessel (), subjecting the ball () to a magnetic field so as to move the ball along the raceway () in an oscillatory motion, exposing the blood sample to an incident light beam (), detecting a light beam () transmitted through the reaction vessel () and coming from the incident light beam () 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 (), 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 of the blood sample from the first signal, and determining a second value of the coagulation time of the blood sample from the second signal.

A novel method for determining the amount of an analyte in a sample comprising an initial purification step, occurring in a first container, comprising the following steps of mixing the sample, a delipidation agent and magnetic particles coated with first analyte binding partners in the first container, incubating the mix, removing the unbound reagents from the mix, and eluting the bound analyte in an elution solution; a transferring step consisting transferring in a volume of the elution solution comprising the analyte from the first container to a second container; and a quantification step, occurring in the second container, consisting of quantifying the analyte in said elution solution.
