Immunoadsorption
Immunoadsorption is a procedure that removes specific blood group antibodies from the blood.[1] It is needed to remove the antibodies against pathogenicantibodies.[2][3][4]
The procedure generally takes about three to four hours.[5]
Immunoadsorption was developed in the 1990s as a method of extracorporeal removal of molecules from the blood, in particular molecules of the immune system.
Different number of devices/columns exist on the market, each with a different active component to which the molecule of interest attaches, allowing for selectivity in the molecules of interest.[citation needed]
Immunoadsorption may be used as an alternative to plasma exchange in certain conditions.[6] Evidence of benefit is lacking in those with kidney problems. Concerns include that it is expensive.[7]
