Journal Title: Journal of Evolution of Medical and Dental Sciences - Year 2018, Vol 7, Issue 31
Abstract
BACKGROUND The ABO blood group and Rh type is unique to every single individual. Prevalence of blood groups of all four types is different in various regions of this world. Aim: The present study is intended to detect the prevalence of blood group among blood donors in West Bengal, the eastern state of India. MATERIALS AND METHODS Blood donors donating blood to Institute of Blood Transfusion Medicine and Immunohaematology (IBTMI), Kolkata, West Bengal are studied. Over 2 lac blood donors for more than 2 years are tested for blood group and Rh type. Donors are categorised according to sex and the prevalence of blood group is tested. Data collected by IBTMI is used as secondary data. RESULTS The study results show the prevalence of blood group in this region as B > O > A > AB. The percentages of B +ve, O +ve, A +ve and AB +ve are 35.6%, 30.7%, 21.84% and 8.82%. The prevalence of Rh negative type is 2.96% (average). These are found to be similar in both sexes. CONCLUSION As different parts of the world have different distribution of blood group, the distribution of blood group in this particular part of the country is determined. This improves our knowledge on prevalence of blood group in the region of the country we live in.
