Geographical distribution of ABO and RHD antigens is important for blood transfusion
services and population genetics studies. There are few data on this topic in
Burkina Faso, a multi‐ethnic country. Our study aims at reporting phenotypic and
allelic frequencies of ABO and RHD blood groups among voluntary blood donors
from various ethnical regions of Burkina Faso. We conducted a cross‐sectional study
including 81,486 blood donors. ABO allelic frequencies were determined using the
Bernstein method. Differences in phenotypic distribution of blood groups were assessed
using the chi‐square test; a p value B+A+AB+O‐B‐A‐AB‐ in our population.
Phenotypic frequencies of blood groups A, B, O and AB were respectively 22.54%,
28.56%, 43.30% and 5.60%. RHD+was 92.24%. The allelic frequencies of A, B, O and
D were respectively 0.1524; 0.1887; 0.6590 and 0.7214. We noticed statistical differences
