1. A method for determining the physical characteristics of a blood sample, comprising:

  • producing a first signal indicative of a measurement of fibrin polymerization of a blood sample over a period of time;

    providing an analytical model of fibrin polymerization of the blood sample over a period of time, the model representing a relationship between initial concentrations of plural blood factors and fibrin polymerization at least in part by one non-linear function having a plurality of coefficients which are related to the initial concentration of plural blood factors through multivariate backward correlation; and

    curve fitting the model to the first signal to produce an output representing values of the plurality of coefficients causing the model to conform to the first signal, wherein the values of the plurality of coefficients are used to identify physical parameters of the blood sample.
