Rare ABO Discrepancy in Multiple Myeloma: An Immunohematologic Challenge with Critical Transfusion Implications : Case report

2026-05-26

Abstract excerpt

<title>Abstract</title> <p>INTRODUCTION: Multiple myeloma is a malignant hematologic disorder characterized by clonal proliferation of plasma cells, leading to excessive production of monoclonal protein and humoral immunodeficiency due to decreased normal immunoglobulins. This condition may interfere with ABO blood grouping and result in discrepancies between forward (cellular) and reverse (serum) typing. We repo...
