Red Cell Alloimmunization in Repeatedly Transfused Sudanese Patients with leukemia in Northern Sudan.

Background: Leukemia frequently causes anemia; thus patients need products containing normal blood or RBCs for treatment. Anti-red blood cell alloantibody formation is still a critical challenge in transfusion.

Objectives: The current study aimed to investigate RBC alloantibodies in Sudanese leukemia patients who receive multiple blood transfusions at the cancer center in Dongola and Maroyee, Northern Sudan.
