Determination of the Frequencies of ABO, A subgroup & Rhesus Blood group among AL Kawahla Sudanese Ethnic Group in Al Jaziera State

Abstract

There are differences in the distribution of ABO, subgroup ABO and Rh (D) blood groups in different populations of the world. Relatively little information was available about blood group distributions in AL Kwahla Sudanese population. Research on ABO group system has been of immense interest, due to its medical importance in different diseases. The ABO blood group system is not only important in blood transfusions, cardiovascular diseases, organ transplantation, erythroblastosis in neonates, but also one of the strongest predictors of national suicide rate and a genetic marker of obesity. This study was carried out to estimate the frequencies of ABO blood group, ABO sub group & Rh phenotype among AL- Kwahla Sudanese ethnic group in the period between February to May 2012, in AL Jazeira State. One Hundred (61male & 39 female) samples were collected as venous blood and the direct blood group was estimated by slide method, and Rhesus blood grouping was performed by using tube technique. The population selected was from village (e.g. Wad shama, Gesm alla, Wad AL Amrabi) The result was analysed by using SPSS computer program count the frequencies of each blood group antigen. Results show as follows: the frequency of O% was found to be 56%, A% was found 23%, B% was found 21% and AB% was found 0%. Sub group of A was mainly A1% was found to be 23%. Frequency of Rh system followed as D% antigen was 91%, C% was 37%, c was 89%, E% was 47%, and e% was 74% .The highest frequency of Rh phenotype was CDe% (29%) and the lowest frequency was Cde% and CD% both was (1%).
