Abstract

The purpose of presenting this case study is to raise awareness of Type III ABO discrepancies in Transfusion Medicine (TMED). Type III ABO discrepancy occurs when agglutination in testing is due to a red blood cell abnormality and does not signify a positive result. In this case study a discrepancy occurred with the blood of a patient needing a transfusion. The similarities in the laboratory results of this particular case and those of patients with Multiple Myeloma or Cold Agglutinin Disease provide evidence that red cell abnormalities have an effect on blood typing results. With knowledge of such errors, technologists may fix the problem and correctly type a patient's blood. Recognition of such discrepancies can facilitate future laboratory testing and reduce the number of false positives in ABO blood typing. Any manner in which transfusion errors can be avoided can improve the chances of accuracy in TMED and therefore have an immediate impact on a patient's life.
