WebMiscellaneous Causes of ABO Discrepancies. Miscellaneous problems may cause ABO discrepancies, including: Cold reacting autoantibodies that result in spontaneous RBC agglutination or a positive direct antiglobulin test (DAT) Mixed red blood cell populations due to massive transfusion. Unexpected alloantibodies unrelated to ABO antigens. WebA mixed field appearance in the post transfusion DAT (i.e. agglutination of donor RBCs and no agglutination of the patient’s RBCs) may or may not be seen. The DAT may be negative in a hemolytic transfusion reaction if all the transfused RBCs have been hemolyzed. Therefore, a negative DAT does not rule out a hemolytic transfusion reaction.
