Polyvinylpyrrolidone in hemodialysis membranes: Impact on platelet loss during hemodialysis.

Polyvinylpyrrolidone content and elution differ between commercially available dialyzers and were found to be linked to the membrane material and sterilization method. The amount of non-eluted PVP on the blood-side surface may be an important determinant for the biocompatibility of dialyzers.
