Prevalence and Distribution of ABO and Rh (D) Factor among Blood Donors in the United Arab of Emirates

Abstract Introduction/Objective Karl Landsteiner discovered the ABO blood group system in 1900, which was the first human blood group system. The Rh blood group system was found forty years later. The antigens on the surface of red blood cells are used to classify people into ABO blood groups. In the ABO system, there are four types: A, B, AB, and O; in the rhesus system, there are two types: Rh-positive and Rh-negative. Blood group identification is critical for efficiently managing blood banks and blood transfusion services to avoid serious transfusion reactions. Methods/Case Report The study was performed on a total of 5996 healthy blood donors in the United Arab of Emirates (UAE). ABO and Rh (D) groupings were performed on all donors' samples by the gel electrophoresis technique. Data on the frequency of ABO and Rh(D) blood groups were reported in numbers and percentages. Results (if a Case Study enter NA) The study revealed that type O is the most prevalent blood group in the United Arab Emirates (43.83%), followed by A at 26.68% and B at 23.90%, with AB having the lowest prevalence at 5.58%; O > A > B > AB. Our study found that 92.57% of the donor population was Rh-positive, whereas 7.43% was Rh- negative. The IA, IB, and IO allele frequencies were determined using the Hardy-Weinberg rule of equilibrium. The gene frequencies are calculated to be 0.1942 for IA (p), 0.1438 for IB (q), and 0.6620 for IO (r). O (r) has the most value in UAE, followed by A (p) and B (q); O > A > B. OO constituted 43.83% of the homozygous types, AA 3.77%, and BB 2.06%. The heterozygous types were 25.71% for AO, 19.03% for BO, and 5.58% for AB. Conclusion The study gives reliable ABO gene frequency statistics and information on the distribution of ABO blood group Rh groups of various alleles in the United Arab Emirates. This knowledge aids in the efficient management of the blood bank's inventory. It will aid transfusion services in anticipating future health issues and improving blood transfusion practice.
