The Rhesus (Rh) blood group system is one of the most polymorphic and immunogenic systems known in humans, because of its immunogenicity along with ABO grouping, This is a cross-sectional study was conducted at national blood transfusion center at Khartoum State to determine the frequency of various Rhesus antigens among Sudanese blood donors in order to minimize Rhesus allo-immunization among Blood recipients. It included 200 donors males from different tribes.The blood were collected from volunteers. ABO grouping was performed by slide method and Rhesus grouping was done by tube method using commercially available standard antisera tested (anti-D, anti-C, anti-c, anti-E,and anti-e). Among the participants (86%) of donors are Rh D positive and (14%)Rh D negative, The percentage of Rh Antigens were e (79.5%), c (68.5%), C (27%), and E (18.5%) respectively .The study shows that the frequencies of the Rhesus antigens were similar to studies in other countries.
