What is apheresis?
Apheresis is a medical procedure that involves removing whole blood from a |donor| or patient and separating the blood into individual components so that one particular component can be removed. The remaining blood components then are re-introduced back into the bloodstream of the patient or donor.
Apheresis is used for the collection of donor blood components (such a platelets or |plasma|) as well as for the treatment for certain medical conditions in which a part of the blood that contains disease-provoking elements is removed.
Apheresis is also called pheresis or hemapheresis. The terminology used may also reflect the component of blood that is being removed, such as:
- Plasma (|plasmapheresis|)
- |Platelets| (plateletpheresis)
- |Leukocytes| (leukapheresis or leukopheresis)
- |Lymphocytes| (lymphopheresis or lymphapheresis)
- |Red blood cells| (erythropheresis)
Total plasma exchange (removal of plasma and replacement with fresh frozen plasma) can also be performed using the apheresis procedure. It is also used for the collection of |stem cells| from the peripheral blood.
