ASSOCIATION OF BLEEDING TIME (BT) AND CLOTTING TIME (CT) WITH ABO BLOOD GROUPS IN MBBS STUDENTS OF RANI DURGAVATI MEDICAL COLLEGE, BANDA: A CROSS SECTIONAL STUDY

Abstract

Background: Blood group is not only a part of identity but also has a crucial role in the field of transfusion medicine. The relationship between bleeding time, clotting time and blood group is especially relevant in certain clinical conditions like surgery, thrombosis, and epistaxis. Several studies have found variations in bleeding tendencies among different ABO blood groups.Hence this study was done to find the association of bleeding time and clotting time with ABO blood groups.
Objective: To compare the bleeding time and clotting time among various ABO blood groups.
Materials and Methods: 192 MBBS students, between the age group of 17-22years, of Rani Duragavati Medical College, Banda, Uttar Pradesh, were enrolled after taking written informed consent. Bleeding time was estimated using Duke’s method, clotting time using capillary tube method and blood group using standard antisera.
Results: Among 192 students, the most common blood group was B (35%), followed by O (31%), A (21%) and AB (13%).The significance of association of bleeding time and clotting time with ABO blood groups was determined using Kruskal-Wallis test. The test revealed that the distribution of bleeding time and clotting time is same across different ABO blood groups. So, there is no significant association of bleeding time and clotting time with ABO blood groups (p=0.087 for BT; p=0.112 for CT).
Conclusion: There was no significant association between bleeding time, clotting time and ABO blood groups.
