The fibers or plates act as a semipermeable membrane across which blood and dialysate flow. By crossing this membrane, solutes and water move between a patient's intravascular compartment and the dialysis fluid contained within the dialyzer. ...Read more

This is the reason for extensive testing and counseling before transplantation. ...Read more
