Abstract
It is important to perform an in vivo module performance to select an optimum dialyzer for each patient. The correlation between in vitro and in vivo performance of dialyzer was investigated. The results show high correlations between in vitro and in vivo results on dialyzer clearance CL and ultrafiltration coefficient UFR. It is possible to estimate in vivo CL and UFR from the data of in vitro CL and UFR. The estimation of in vitro performance is a first step toward the clinical use of dialyzer.
