The purpose of this study is to raise awareness of discrepancies in ABO typing and cross-matching in patients with multiple myeloma. In transfusion medicine an ABO discrepancy occurs when the forward typing of a blood group is inconsistent with the reverse typing. A cross-match discrepancy occurs when the plasma or serum of a patient is tested and reacts with a prospective donor’s red cells. Without the ability to correctly identify ABO blood type and rule out incompatibility, the patient cannot receive a transfusion. The case study being presented demonstrates a multiple myeloma patient whose laboratory results correlate with a cross-match discrepancy. Recognition of such discrepancies can facilitate the effectiveness and efficiency in future laboratory testing of multiple myeloma patients.
