Our latest addition to Blood Type Frequencies by Country including the Rh Factor is the Democratic Republic of the Congo.
The determination of blood groups appears to be very useful in transfusion
medicine, genetics, forensic medicine, organ transplantation and maternal alloimmunization.
In Moba, blood transfusion is indicated in several anemias of
the children. The present study aimed to determine the frequency of ABO and
Rhesus blood groups in our environment. This is a descriptive cross-sectional
study. Blood donors registered at the Moba General Reference Hospital for the
period 2015 to 2016 were selected for this study (n = 2292). The Beth-Vincent
test was used to determine blood group phenotypes from the monoclonal test
sera. Blood groups O (60.5%) and AB (2.5%) were respectively the most frequent
and the least encountered. In our series of studies, the numerical frequency
order of the phenotypes of the ABO and Rhesus (D) blood groups included
in order of importance: O+ (n = 1364 or 59.5%); A+ (n = 488 or 21.3%);
B+ (n = 348 or 15.2%); AB+ (n = 55 or 2.4%); O− (n = 22 or 1.0%); A− (n = 7 or
0.3%); B− (n = 5 or 0.2%); and AB− (n = 3 or 0.1%). This observed difference
between the different ABO and Rhesus groups is significant. Sex does not significantly
affect the type of blood group. The distribution of ABO and rhesus
groups follows the same Negroid distribution as in many countries. The results
should be capitalized for proper priority management of the blood to be
stored in the blood bank.
