Introduction: ABO and Rh-blood groups vary among different populations in the world. Also, this variability of blood groups has been observed in different geographical regions and populations within a country. Determination of ABO and Rh-blood group distribution in a country plays an important role in blood transfusion and many fields of medicine.
Aim: To determine distribution of ABO and Rh-blood groups among patients admitted to gynaecology, obstetrics and children Hospital in Konya, Turkey.
Materials and Methods: A total of 30291 patients were included to this retrospective study between September 2015-December 2017 for a period of 27 months. Patients were divided into two major groups according to age. There were 29548 (97.5%) women in the age group of 17-75 and they admitted to gynaecology and obstetrics departments. The number of children in the age group of 0-16 were 743 (2.5%) and they were admitted to paediatrics departments. ABO and Rh-blood group tests were performed by gel centrifugation method on fully automated immunohematology analyser. Data analyses were performed by using chi-Square and Monte Carlo exact test.
Results: A Rh-positive had the highest rates (37% and 35.4%) among women and children, respectively and was followed by O Rh-positive (28.4%, 29.8%), B Rh-positive (16.1%, 16.9%) and AB Rh-positive (7.3%, 6.8%). AB Rh-negative had the lowest frequency as its rate was under 1%. The rate of Rh positivity was 89% and that of Rh negativity was found to be 11% in both study groups. Distribution of blood groups according to gender among children population was not found statistically significant (p>0.05).
Conclusion: The present results were similar to data obtained from previous studies in Turkey, but indicated a different ABO and Rh-blood group profile compared to many studies worldwide because of genetic and ethnic factors. Authors think the present study will contribute to literature by reporting the knowledge of blood group distribution in different populations and creating a database for blood banks in our country.
