Investigation on the Middle Size Molecule Elimination Characteristics of the FXCorDiax 100 in Relation to the FX 100 and the Polyflux 210 H Dialyser

The purpose of the study is to compare clearance and removal rates of phosphate, ß2-microglobulin (ß2-m) and leptin and albumin loss with different dialyser membranes during post-dilution online hemodiafiltration.

• who are on a regular thrice weekly HDF schedule, e.g. Monday-Wednesday-Friday or Tuesday-Thursday-Saturday,
• who have a good vascular access (fistula or graft) which enables easy insertion of the needles and suitable effective blood flow (> 300 ml/min)
• who are able to understand the nature and requirements of the clinical investigation and who have given written informed consent
