ABO and Rhesus Blood Group Distribution in Mogadishu, Somalia.

Purpose: Our aim in this study is to reveal the blood group distribution by investigating retrospectively the blood types of around 60 thousand patients and donors who applied to Mogadishu Somalia Turkey Recep Tayyip Erdogan Training and Research Hospital between 2018 and 2021.

Patients And Methods: The blood group data of 59,442 people were included in this study. 20,414 (34.35%) of the study's participants were female, 39,023 (65.65%) were male. The blood groups of participants were determined using the slide method and the gel column technique. The frequencies and percentages of O, A, B, AB and Rh blood groups were calculated.

Results: The frequencies of ABO blood group distribution indicated that blood group O and Rh+ were predominant in Mogadishu O group: 60.30%, A group: 26.50%, B group: 11.27%, AB group: 1.93%, Rh+ group: 96.49%, Rh- group: 3.43%.

Conclusion: This is the first study about blood group distribution in Mogadishu based on a large number of blood type tests and hospital data. The findings of our study can guide the blood center administrators make decisions concerning blood stocking and supply. This study can give an idea about how much fluctuations may occur in the frequency of blood group types in emigrant populations over many years.
