ABSTRACT

Objective: To determine Rhesus antigens (D, C, c, E, e) distribution among Sudanese blood donors attending Central Blood Bank in Wad Madani, Gezira State, Sudan and to minimize Rhesus allo-immunization among blood recipients. Material and Methods: 2.5 ml of blood was collected from 132 blood donors under a septic condition in Ethylenediamine tetra-acetic acid (EDTA) containers, mixed well and labeled, ABO and Rhesus typing were performed using the classical slide method. Results: The study revealed that frequency percentage of ABO blood phenotypes in the total samples were as follows: O (55%), A (23%), B (20%) and AB (2%); whereas the frequency percentage of Rh antigens were e (100%), c (93%), D (92%), C(43%), E (16%). Conclusion: The study revealed that Rh e antigen had highest prevalence in all the study population while Rh E antigen is the lowest one.
