Plasmapheresis, also known as therapeutic plasma exchange (TPE), is a nonsurgical therapy that removes and replaces a patient's blood plasma.
The Apheresis Program at UC San Diego Health is the most established outpatient therapeutic plasmapheresis center in San Diego County.
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). The substitute plasma and the patient's own blood cells (red cells, white cells and platelets) are returned to the patient through a return needle.
