    摘要： The invention relates to time-course measurement of enzymatic activity corrected for impacts of disturbances relating to the reaction of the enzyme with a substrate.
    The in vitro method of the invention is especially intended for the measurement of clotting or the fibrinolysis activity in vitro .
    The invention enables to measure the exact time course of an enzymatic activity that develops and/or disappears in a reaction mixture, especially in a blood sample.
    The invention thus relates to a method of determination of the course of an enzyme activity that is variable in time, wherein said activity is probed by conversion of a substrate of the enzyme, comprising, in a selected test set up and for a determined substrate of the enzyme, the determination of the velocity of signal production (dF diag /dt) resulting from a time curve of the signal (F diao =f(A)) obtained from splitting said substrate when it is contacted with a determined initially fixed concentration of the enzyme (E) and providing a "diagnostic plot" with the values of (dF diag /dt) against the signal (F diag ) and determining whether said diagnostic plot is either a straight line or a parabola and in the same test conditions, for a given test sample, the determination of the signal production (F exp ) resulting from splitting the substrate by the enzyme generating in and/or disappearing from the sample and providing the time curve of signal F exp =f(t); and transforming the obtained experimental value of the signal (F exp ) into an ideal value (F transf )
