In plasmapheresis, antibody-laden blood plasma (the liquid portion of the blood) is removed from the body. Red blood cells are separated and put back into the body with antibody-free plasma or intravenous fluid.
Plasmapheresis is a medical procedure where blood is separated into its various components, with plasma being removed and replaced with a substitute fluid or donor plasma. This technique can be used to remove harmful substances from the blood, such as toxins or autoimmune antibodies, and is commonly used in the treatment of certain autoimmune disorders.
