Eluate

An eluate in blood bank language is the solution that is available for analysis after an elution is performed (the removal of antibody coating the surface of a patient’s red blood cells through physical or chemical means). The eluate is expected to contain any dissociated antibody or antibodies, and it can be tested against reagent red cells to determine the specificity of the antibody. Eluates are useful in complicated antibody identification procedures, as well as in the investigation of positive direct antiglobulin tests and autoantibodies.
