Claim Text:
1. A method comprising: receiving a blood sample in an electrochemical cell comprising a plurality of electrodes, such that the blood sample and the plurality of electrodes are connected in a circuit; applying an electrical potential difference across the blood sample; measuring, over a measurement time duration, an electrical signal passing through the blood sample; recording a plurality of measurements representing a measurement function over time; and determining an accumulative property of the measurement function based at least on an equation: wherein Δt is a time span between a first peak and a second peak of the measurement function; A 1 is a first area computed by integrating variable values of the measurement function over the time span; A 2 is a second area computed by integrating a difference between the variable values and a fixed minimum value of the measurement function over the time span; and n, m, and p are empirical parameters; and wherein the accumulative property relates to one or more blood coagulation characteristics.
