ABSTRACT:
A method for determining the adequacy of dialysis, using determination of urea concentration in the dialysate effluent with an enzymatic electrode incorporating a urease sensor, and conversion of this information to arterial urea nitrogen utilizing a "flow ratio" correction; and utilizing the arterial blood urea nitrogen derived from readings of an on-line monitoring sensor as an absolute quantity, and the urea reduction ratio as a relative quantity as a new end-point for dialysis adequacy.
