Thanks for telling me that the link didn't work. I edited my posting and took out the period so now you can click on it and (hopefully) get the article I meant people to know about.
You're right, Fresenius clinics don't reuse dialyzers any more. Fresenius has dialysis clinics and makes dialyzers that their clinics and other clinics buy. If their clinics can purchase the dialyzers from the parent company at a reasonable price, it probably isn't cost effective for Fresenius to reuse dialyzers. Reuse is not without its own costs -- reuse equipment, supplies, reuse tech, equipment to monitor air quality, venting, extra water, etc. And this doesn't take into account the symptoms that some patients have with reused dialyzers.
