title: [ABO polymorphism in blood donors in Morocco].
abstract: Blood grouping were improved since the advent of monoclonal antibodies and the automation of the tests. No comparative study has been done before in Morocco concerning ABO regional genetic frequencies. Hence, the aim of this work is to actualize and to precise them. The ABO blood grouping has been carried out on 344 954 blood donors by micro method in several regional blood transfusion centers. Genetic frequencies were calculated according to the Bernstein's method. The national mean values are A: 0.2141, B: 0.105, O: 0.6777. The regional frequencies show gradients between the north and the south of Morocco.
