What does plasmapheresis remove?
Plasmapheresis involves removing blood through a needle or catheter and circulating it through a machine where the blood is separated into red cells, white cells, platelets and plasma. The plasma, which is the fluid content of the blood, is discarded and replaced with a substitution fluid (mainly albumin solution).
What is plasmapheresis dialysis?
Plasmapheresis is similar to dialysis; however, it removes the plasma portion of the blood where the antibodies are located. Plasma is the almost clear part of the blood which carries red cells, white cells, platelets and other substances through your bloodstream.

Can plasmapheresis cause kidney damage?
Plasmapheresis before transplant removes antibodies against the donor blood-type from the recipient, so they can’t attack and damage the donated kidney. Depending on the antibody levels and the transplant center protocols, a medicine to keep more antibodies from forming may also be administered intravenously.
Why would you need plasmapheresis?

By depleting the body of inflammatory factors, plasmapheresis may give the immune system an opportunity to re-adjust itself. This may be possible in part via induction of regulatory T cells through reducing the inflammatory cytokines found in the patients’ plasma.
How long does plasmapheresis stay in your system?
Does plasmapheresis remove good antibodies?
Plasmapheresis is a process that filters the blood and removes harmful antibodies. It is a procedure done similarly to dialysis; however, it specifically removes antibodies from the plasma portion of the blood.
