The Frequency of ABO , Rh (D) & Kell (KPa & KPb) Blood Group Antigens & Phenotypes among ALShaigia Sudanese Tribe

Abstract

Objective: This is adescriptive, prospective and analytical study aimed to determine the frequency of ABO, Rhesus (D) and Kell (Kpa&Kpb) antigens and phenotypes. Methods:The study was carried out during the period of three months (Marsh to June 2007) in Alshaigia Sudanese tribe .Following informed consent, a total of hundred venous blood samples were collected into 2.5 ml EDTA containers from unrelated individuals. All samples were tested for ABO and Rhesus (D) antigens using slide method whereas the modern technique called the gel particle immunodiffusion was used for determination of Kell (Kpa&Kpb) antigens. Result: Regarding to ABO blood group antigens the result revealed that: The O antigens was the most common (48%) followed by A antigens (26%) and B antigens (23) whereas the AB antigen was least common (3%). Rhesus (D) was most frequent, with the frequency of (96%). Concerning Kell (Kpa&Kpb) antigens, the Kpb was the highly frequent (100%), while the KPa was least common (2%). Method analyzed:The results were analyzed by the SSPS computer program and to compare between study tribe and other Sudanese tribes and other countries determined by Jaccard's coefficient of similarities. In conclusion there were similarities between state them (due to intermarriage) and differences with the others (may explained by the differences in geographical locations).
