Removing warm auto antibodies for compatibility testing

[Category : - HEALTH- CHEMISTRY]
[Viewed 2166 times]

The invention provides a new method for antiglobulin testing from serum of a potential blood transfusion recipient in which warm autoantibodies are removed from serum so as to allow identification of alloantibodies present. The method involves contacting serum from a patient with one or more ligands that bind warm autoantibodies but do not bind alloantibodies, separating the non-bound serum components from the bound warm autoantibodies, and using the warm autoantibody-depleted serum in antiglobulin testing. Suitable ligands include phospholipids, the polar head groups of phosphoglycerides, and naturally occurring and synthetic analogues of these molecules.
