Background: Blood group status is essential for blood grouping, crossmatching, and medicolegal aspects. The ABO system and the Rhesus system (Rh) both influence blood group distribution. Blood coagulation tests, such as bleeding time (BT) and clotting time (CT), are crucial for surgery planning and assessing anticoagulant responses. BT is affected by platelet function, while CT is influenced by clotting factors.
Objectives: To determine undergraduate students’ blood groups; to investigate the effect of the Rhesus factor on BT and CT.
Methods: Institution-based cross-sectional observational study at Tripura Medical College and Dr BRAM Teaching Hospital. BT and CT assessed using Duke's method and capillary glass tube method, respectively. Blood groups determined based on agglutination presence or absence. Qualitative data expressed as percentages, quantitative data with mean and standard deviations. Analysis of variance (ANOVA) and Chi-squared tests used.
Results: A total of 61 females (58%) and 44 males (42%) participated. Blood group B+ (31.4%) and O+ (30.5%) were the most predominant, followed by A+ (21.9%) and AB+ (9.5%). Differences in BT and CT across blood groups were observed but not significant.
Conclusion: Blood group B+ and O+ were most common. Coagulation tests, BT and CT, varied across blood groups but were not significantly different.
