Positive tests will be further evaluated for bound and unbound antibody specificities associated with Cold Hemagglutinin Disease, Warm Autoimmune Hemolytic Anemia, and delayed reaction to transfusion. Positive tests will be further evaluated to determine the specific type(s) of protein adhering to the red cells and present in the serum (indirect test).
