Red-cell alloimmunization profile in multi transfused patients: Findings and insights of a blood transfusion service.

Objectives: Blood transfusion is a key intervention for decreasing morbidity and mortality in many cases and, besides its importance, potentially fatal consequences of incompatible transfusion are a great risk to patients. This study evaluated the incidence and specificity of erythrocyte alloantibodies in multi-transfused patients enrolled at an important Regional Blood Center.

Materials/methods: This was a single-center retrospective cohort study that eveluated patients enrolled at a Regional Blood Center in a period of four years.
