Red cell alloimmunisation in oncology patients: A study from eastern India

Our overall red cell alloimmunisation rate was 2.5%. Alloimmunisation rate among HSCT transplant patients was 1.6% as compared to the 2.4% in patients with solid organ malignancies. Keeping in view the low alloimmunisation rate, the justification of repeating antibody screening 72 hours post transfusion in this category of patients needs to be re-assessed.
