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 prospective study was carried out at the North Bengal Medical College, Siliguri, West Bengal from 2013 to 2018. The blood groups and Rh type of medical students were recorded. Haemoglobin concentration was obtained using cyanomethmoglobin method. RESULTS: Of the total 590 students B group was most prevalent (44.6%) followed by O group (30.5%). Prevalence of Rh positive type was 94.1% and Rh negative was 5.9%. Rh negative type amongst males was 3.0% and females it was 2.9%. In the study 35.9% were 19 years of age and 28.6% were 18 years. In the study 62.0% were male students and 38% were females. 16.3% of the female students had haemoglobin levels of 11 – 13 gms/dL compared to 11.2% male students. 14.4% of the female students had 13 – 15 gms/dL compared to 25.8% of male students. 11.7% of students were from the district of Coochbehar followed by Darjeeling (9.2%) followed by Kolkatta (8.8%). No students were from Bankura and Jhargram districts, and 1.5% were from Alipurduar and 1.7% were from Paschim Mednapur and North Dinajpur. DISCUSSION AND CONCLUSION: B group was the most prevalent followed by O group. 94.1% were Rh positive and 5.9% were Rh negative. 20.9% of the students were from Coochbehar and Darjeeling districts, combined, due to their proximity to Siliguri and students from districts far distance were found in increasingly less numbers.
