Abstract
Methods for measuring the effect of dialysis treatments are disclosed in which a fraction of the used dialysis fluid is extracted downstream of the dialyzer for analysis of at least one substance such as urea, and in which the fraction of dialysis fluid is extracted through a branch conduit containing a pump. In accordance with this method, the total amount of used dialysis fluid is measured and the concentration of that substance in the extracted fraction is measured, and the total amount of that substance removed from the patient can then be calculated from these values. This invention is preferably intended for use in connection with hemodialysis, hemofiltration and hemodiafiltration.
