Determination of The Frequencies of ABO And Kell Phenotypes In Al- Bani Amer Tribe

Abstract

These study was carried out among Bani Amer tribe in eastern Sudan to determine the frequency of ABO and Kell phenotypes. Hundered samples were collected from unrelated donors of Bani Amer individuals,investigated by direct agglutination technique for ABO system screening and by gel immunodifusion technique to detect Kell phenotypes. Data were analysed by computer using SPSS program. The frequency of group A blood was 33%, B 17%, O 47%, and group AB blood was 3%. The frequency of Kell-1 (K1) was found to be 7% and Cellano (K2) was 100%. The study showed that there is no statistical significant association between the occurance of Kell phenotypes ( K1 , K2 ) and gender, as well as phenotype of ABO blood group. It was concluded all Bani Amer patients and donors should be screened for Kell blood group phenotypes as a part of compatibility testing before transfusion.
