Abstract

Background: Blood group and its relation to bleeding time (BT) and clotting time (CT) is important in clinical conditions like epistaxis, thrombosis, and surgery. Earlier studies depicted O group having prolonged BT and CT. Objectives: The aim of this study was to assess the relationship of BT and CT with ABO groups. Material and Methods: This cross-sectional study was conducted in the Department of Physiology, Veer Surendra Sai Institute of Medical Sciences and Research. The study included 150 students. Blood grouping was determined with the standard antisera; BT and CT were estimated by the Duke method and Wright’s capillary glass tube method, respectively. Blood group and its relation to BT, CT were analyzed by Chi-square analysis.
Results: Blood group O (40.7%) was predominant in both genders followed by B (32.7%), A (18%), AB (8.7%). CT was found to be more than 6 min in group O (31.57%) followed by group AB (26.31%), A and B (21.05%). The difference was statistically significant ( p = 0.02). BT was found to be more than 4 min in group O (82.35%) followed by A (11.76%), B (5.88%), and AB (0%). That was statistically significant ( p = 0.01). CT was more than 6 min in 57.89% in females as compared to 42.10% in males, variation was statistically significant ( p = 0.01). BT was more than 4 min in 58.82% females as compared to 41.17% in males. The variation was statistically significant ( p = 0.03). Conclusion: In our study blood group O was more common followed by B, A, and AB. CT and BT were prolonged in O group. BT and CT were more in females than males.
