Abstract:
This was descriptive, prospective and analytical study conducted in
Khartoum State in the period of March to June 2007 to determine ABO
and Rh phenotype frequencies among Alnuba Sudanese population, this
study was included hundred (100) unrelated volunteers from (Aluoba)
tribe, in different ages and both sexes (Males and Females), the consent
of the selected individuals to the study was taken after being informed
with all detailed objectives of the study and its health emphasis in the
future.
The questionnaire was specifically designed to obtain in formations
about name, sex, tribe, age, living place, origin place, telephone and
present of pathological condition.
The laboratory method used to demonstrate ABO Ags was manual
slide method by use convention ABO anti sera ,where manual tube
method was used for Rh Ages in addition to automated techniques ( Gel
Immune Diffusion ).
The percentage of ABO Blood group among Alnuba Tribe were found
to be 60 % of them were group O , 29 % group A, 10 % group B, and 1
% group AB . The result showed high frequency of group O and Low
frequency in group AB, the percentage of (positive – negative) Rh Fisher
classification antigens demonstrated as 92 % of the study groups were
positive D antigen, while 8% of them were negative. C antigen positive
in 6% and 94 % of them were negative. 97% of Alnuba tribe was positive
c antigen while 3 % of them were negative. E antigen positive was found
in 9 % and negative was in 91% of them. e antigen positive in 92 %, and
8 % of them were negative ,the most common ABO blood group was
group O while AB was the less common ,but the most common Rhesus
phenotype was c,D, e in contrast C,E found with low
frequencies among the study group.
The collected data analyzed using SPSS computerized programmed to
calculate the percentage and frequencies of these Ags.
The results of ABO and Rh (D) Ags in this study showed similarity
With others studies included distribution of blood groups among city
Mashhad in North East of Iran and frequencies among Yoxuba and
Hausa in Nigeria.
