High-Performance Membrane Dialyzers

Dialyzers today are developed with high permeability and biocompatibility in mind, even though the definition of these so-called high-flux dialyzers remains controversial. In the Japanese reimbursement system, dialyzers are divided into five types, ranging from I to V, in accordance with their clearance for beta2-microglobulin (beta2-MG). Classes IV and V (beta2-MG clearance greater or equal to 50 and 70 ml/min, respectively, at a blood flow rate of 200 ml/min) are the most common ones, used in
