AN OBSERVATIONAL STUDY: ASSOCIATION OF BLOOD GROUPS WITH BLEEDING TIME AND CLOTTING TIME

Abstract

Objectives: The objective of the present study was to assess the relationship between bleeding time (BT) and clotting time (CT) among various blood groups and also to identify gender differences if any. Methods: The study was conducted in a tertiary care center. The study included 108 MBBS students, 68 were males and 40 were females. BT was obtained by the Duke method and CT was estimated by Wright’s capillary glass tube method. Standard antisera were used to know the blood groups. Blood group and its relation to BT, CT, and gender were analyzed by Chi-square analysis. Results: Blood Group B (33.33%) was predominant followed by O (32.4%), A (21.29%), and AB (12.96%). CT was found to be more than 6 min in Group O followed by B, A, and AB, and BT was found to be more than 4 min in Group O followed by A, B, and AB. Both were statistically not significant (p>0.05). CT more than 6 min was greater in males (52.17%) as compared to females (47.82%), but the variation was insignificant (p=0.227). BT was more than 4 min in 68.96% of females as compared to 31.03% of males. The variation was statistically significant (p=0.0085*). Conclusion: In our study, blood Group B was more common followed by O, A, and AB. CT and BT were prolonged in the O group. BT was more in females than males, whereas CT was more in males than males.
