When is therapeutic apheresis done?
Apheresis is often done on donors where whole blood is centrifuged to obtain individual components (eg, red blood cells [RBCs], platelets, plasma based on specific gravity) to use for transfusion in different patients. Apheresis may also be used therapeutically to treat various disorders (1.

How long does apheresis take? The treatment takes about 2 to 5 hours, depending on which type of apheresis you get.
How is plasma exchange used in therapeutic apheresis?
Plasma exchange. Therapeutic plasma exchange removes plasma components from blood. A blood cell separator extracts the patient’s plasma and returns RBCs and platelets in plasma or a plasma-replacing fluid; for this purpose, 5% albumin is preferred to fresh frozen plasma (except for patients with thrombotic thrombocytopenic purpura)…
What are the different types of therapeutic apheresis?
The following are different types of therapeutic apheresis ordered based on a patient’s specific condition: plasmapheresis (or plasma exchange), white blood cell depletion, photopheresis, red blood cell exchange,
What does apheresis stand for in medical terms?
Therapeutic apheresis is an extracorporeal treatment that separates blood components (plasma and/or cellular components) from the patient’s blood for the treatment of conditions in which a pathogenic substance in the blood is causing morbidity.
