A procedure that removes the patient’s plasma and replaces it with donor plasma or albumin solution, effectively clearing autoantibodies, immune complexes, toxins, and inflammatory mediators from the circulation.
Therapeutic plasma exchange (TPE), also known as plasmapheresis, is an extracorporeal procedure in which the patient’s blood is separated into cellular components and plasma. The plasma — which contains antibodies, immune complexes, clotting factors, and other proteins — is removed and replaced with a substitution fluid, typically human albumin or fresh frozen plasma.
TPE is one of the most broadly applicable apheresis techniques, with established indications across neurology, hematology, nephrology, and autoimmune medicine.
Blood is drawn through a venous access point and passed through a centrifuge or membrane-based separator that divides plasma from blood cells. The separated plasma is discarded and replaced with an equal volume of substitution fluid. The reconstituted blood is returned to the patient.
A single session typically processes 1-1.5 times the patient’s plasma volume. This achieves approximately 60-70% removal of circulating pathological substances per session. Courses of 3-7 sessions are common, depending on the clinical indication.
Therapeutic plasma exchange is indicated for specific conditions based on clinical guidelines. Our medical team will evaluate your case to determine suitability.
Each plasma exchange session lasts approximately 2-3 hours. The patient is comfortably seated with venous access established. Vital signs including blood pressure, heart rate, and temperature are monitored continuously. Some patients experience mild tingling, lightheadedness, or chills during the procedure, which are managed by the medical team. Patients typically rest briefly after the session before returning to their room.
Therapeutic plasma exchange is one of the most well-studied apheresis procedures. The American Society for Apheresis (ASFA) publishes evidence-based guidelines categorizing indications by strength of evidence. Many neurological and hematological indications are classified as Category I (standard first-line therapy). The procedure carries a low risk of serious adverse events when performed by experienced personnel in an appropriately equipped setting.
