Abstract
In the clinical study the filtration efficiency of the prediluted plasma separation was compared with the conventional method of single and double membrane plasma exchange. From these comparative studies prediluted plasma separation have high efficiency in filtration flux, selective removal of pathogenetic proteins and sparing plasma albumin. The results from the in vitro plasma separation using kuraray t s minifilters of 2A and 4A approved the availability of prediluted plasma separation in single and double membrane plasma separation.
