Recognizing and resolving ABO discrepancies

Patient samples are routinely typed for ABO prior to transfusion. Determining the ABO group requires both red blood cell (RBC) antigen typing for A and B (forward type) and testing for anti-A and anti-B in the plasma (reverse type). An ABO discrepancy exists when the result of an ABO RBC typing, or forward type, does not agree with the result of the plasma typing, or reverse type. This brief review examines several causes of ABO discrepancies encountered in the clinical transfusion service

Serologic problems associated with administration of intravenous immune globulin (IVIg)

anemia.13,17 Thrombosis can also result from IVIg infusion, but this is quite rare compared with IVIg-associated hemolysis.18 In addition to adverse events, administration of IVIg can create challenges for the transfusion service including ABO discrepancies, positive direct antiglobulin tests (DATs), positive antibody detection tests, and incompatible crossmatches. Reverse ABO Grouping Because up to 4 g/kg of IVIg may be given to an individual with blood group A, B, or AB, these patients will often
