Research regarding the frequency of AB0 blood groups in a population of pupils from Piatra Neamt, Neamt County

Part of a larger study regarding the genetic polymorphisms present in the human population of Romania, we have studied the frequency of AB0 blood groups in Piatra Neam , Neam county, at a population of 320 pupils, born between 1992-1997. As controle were used data obtained from Blood Transfusion Centre from Neam county, determination made between 2008-2009. The obtained frequencies were concordant with values obtained at Blood Transfusion Centre, which are normal for the romanian population and for Europe. We are discussing various reasons for the slight regional differences of the AB0 blood group frequencies registered between different romanian regions.
