The frequency of ABO , Rhesus(D) and kell (K1&k2) Blood Group Antigens & phenotypes among Halfaween Sudanese tribe

Abstract

This is a prospective and analytical study, aimed to determine the frequency of ABO, Rh(D) and kell antigens, and phenotypes, among Al halfaween Sudanese tribe. Also aimed at establish ABO, Rh(D) and Kell blood group baseline data for this Sudanese tribe to determine the interaction between this tribe and other Sudanese tribes which will be useful in blood transfusion. The study was conducted during three months (April to July, 2007), Following informed consent, a total of hundred venous blood samples were collected 2.5 ml into EDTA containers from unrelated individual. All samples were tested for ABO and Rh(D) antigenes using the slide agglutination techniques, and kell antigenes were tested by immune-diffusion gel technique. The results obtained showed that, The O group was most common frequently occurred ( 45% ) , followed by group A ( 31%), group B was found ( 21% ) and the least common was group AB ( 3%). The Rh(D) antigen was (87%). K2 was (100%) and K1 was (4%). There was a marked similarities between the Sudanese tribes that lived in the same geographical area, this could be due to intermarriage , while the difference that seen in some tribes could be most probably due to the wandering nature of these tribes.
