Abstract :

Introduction: At present 36 blood group system genes have been identified and sequenced. Each blood group system represents either a single gene or a cluster of closely linked homologous genes. Materials and methods: A retrospective study was carried out at the tertiary care teaching hospital blood bank from January 2012 to December 2017. The blood groups of donors and other relevant data were accessed from the archived records. Results: Of the total 11,615 donors B group was most prevalent (31.63%) followed by A group (30.54%), O group (26.01%) and AB group (11.81%). 93.51% were Rh positive with the remainder (6.49%) being Rh negative. Of the total donors 7.69% were females. Discussion: In our study B group (31.68%) was the most prevalent followed by A group. AB group was the least prevalent. Similar studies in India show prevalence of B group in Rajasthan, Gujurat, West Bengal, Chattisgarh, Orissa and Tripura. Rest of the studies show prevalence of O group. Sikkim was the only state that showed a prevalence of A group. Conclusion: B group was the dominant blood group in our study (31.63%) and Rh negative type constituted 6.65% of the donors. Females made up only 7.68% of donors.
