Calculation of Kt/V in haemodialysis: a comparison between the formulas.

Introduction: The quality of delivered dialysis can be measured by the Kt/V ratio, which can be calculated in various ways.

Objective: To compare the Kt/V ratio obtained with the formulas of Lowrie (L) and Daugirdas (D) with the results measured by an Online Clearance Monitor (OCM).

Method: Observational, cross-sectional study of 59 patients on hemodialysis (HD).
