A Study To Assess The Abo Blood Group Antigen Phenotype And Gene Distribution Among Blood Donors At A Tertiary Care Research Institute In South India

ABO blood group antigens form the basis of current blood transfusion practice and their prevalence among blood donors can provide a glimpse into the population distribution of ABO genes and hence this study was undertaken to assess the ABO antigen phenotype prevalence and ABO gene prevalence among blood donors at a tertiary care teaching research Institute in South India. A total of 49,279 donors have been checked for their ABO blood group. The O, A, B, AB blood group prevalence were 42, 20, 32, 6 percent respectively while the O, A, B gene frequencies were 65, 14, 21 percent respectively.
