    A new equation predicts infinity values in biexponential processes during the early nonlinear phase using equal time intervals. This method is independent of rate constants but sensitive to noise in urine data.

    Area of Science:

    • Biophysics
    • Pharmacokinetics
    • Analytical Chemistry

    Background:

    • Biexponential processes are common in biological and chemical systems.
    • Predicting behavior in the early nonlinear phase is crucial for understanding these processes.
    • Current methods may be limited by dependence on rate constants or sensitivity to data noise.

    Purpose of the Study:

    • To present a novel equation for predicting infinity values in biexponential processes.
    • To enable prediction during the early nonlinear phase with equal time interval sampling.
    • To offer a method independent of specific rate constant values or ratios.

    Main Methods:

    • Development of a new mathematical equation.
    • Application to biexponential processes with samples taken at equal time intervals.

  • Analysis of the equation's independence from rate constant parameters.

    • Main Results:

    • The presented equation allows prediction of infinity values in the early nonlinear phase.
    • The equation is independent of the magnitude or ratio of rate constants.
    • The method demonstrates high sensitivity to noise, particularly in urine data.

    Conclusions:

    • A new predictive equation for biexponential processes has been established.
    • The equation offers a rate constant-independent approach for early-phase analysis.
    • Careful consideration of data noise, especially from urine samples, is necessary for accurate application.
