1. A method of monitoring a hemodialysis treatment in real time for utilization with a hemodialysis machine including a dialyzer and with dialysate waste effluent removed from the dialyzer, comprising:

  • providing a dialysate effluent constituent sensor and separately coupling a plurality of separate, selected volume, fluid portions of the dialysate effluent to said constituent sensor during a dialysis treatment;

    detecting and measuring concentrations of said constituent in each of said dialysate effluent portions;

    determining a dialysate constituent concentration-time profile from said constituent concentration measurements; and

    directly determining an indication of adequacy of said dialysis treatment from said dialysate constituent concentration-time profile prior to the end of a treatment period of, whereby treatment can be adjusted by an amount effective to result in adequate hemodialysis for fixed time-period hemodialysis treatments if the determination indicate the dialysis treatment having its adequacy determined is inadequate.
