Blood Type Frequencies in Argentina

Note: Frequencies of 0 negative blood types can be extraordinarily high due to blood banks spending more efforts to recruit them

Se analizaron los grupos sanguíneos de 73875 dadores de sangre que concurrieron al Banco de Sangre del Policlínico Ferroviario Central, en relación a la provincia o país de nacimiento. Se estudiaron los grupos ABO, el genotipi cde y los fenotipos Cde, cdE y CdE. Se confeccionaron mapas de la Republica Argentina en los que se describe la frecuencia relativa de los grupos sanguíneos estudiados. En base a estos resultados y a los datos del último censo, se estimó la prevalencia probable de los grupos sanguíneos en la población total de la Republica Argentina. Los porcentajes obtenidos para los distintos grupos son: O = 53,8%; A = 34,7%; B = 8,8%; AB = 2,7%; cde = 8,4%; Cde = 0,44%; cdE = 0,21%; CdE = 0,06% y total Rh negativo = 9,11%. Se observó a lo largo del período de estudio, la disminución progresiva en la prevalencia del grupo cde/cde (p+0,047). Se calculó la proporción de los componentes génicos europeo y aborigen de la población argentina, usando como marcadores al grupo 0 y al factor Rh negativo. Los porcentajes encontrados en la población nativa fueron: componente europeo 81,77% y 81,47% y componente aborigen 18,23% y 18,57% (AU)

We analyzed 73,875 blood group of blood donors who attended the Polyclinic Blood Bank Central Railway, in relation to the province or country of birth. ABO groups were studied, the genotypic and phenotypes Cde cde, cde and CoE. Were made maps of Argentina in describing the relative frequency of blood groups studied. Based on these results and census data, we estimated the likely prevalence of blood groups in the total population of Argentina. The percentages for the different groups are: O = 53.8%, A = 34.7%, B = 8.8%, AB = 2.7%; cde = 8.4%; Cde = 0.44% , CDE = 0.21% = 0.06% and CoE Total = 9.11% Rh negative. Was observed throughout the study period, the progressive decrease in the prevalence of group cde / cde (p +0,047). We calculated the proportion of Aboriginal and European gene components of Argentina's population, using as markers to Group 0 and Rh negative. The percentages found in the native population were European component 81.77% and 81.47% and 18.23% Aboriginal component and 18.57% (AU)
