ABSTRACT:
A method for determining the adequacy of dialysis, using determination of urea concentration in the dialysate effluent with an enzymatic 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.
