Difference of Clotting Time and Bleeding Time in the ABO Blood Groups

Introduction: Blood group, clotting time (CT) and bleeding (BT) are vital haematological parameters that tested prior to any surgery. groups associated with various diseases blood group "O" linked nose bleeds. The aim of this study is evaluate the association between CT BT find differences in gender among these parameters. Study Design: A cross-sectional observational study. Place Duration: In department Physiology Medicine, MTI LRH, Peshawar Pakistan for one-year duration from March 2021 February 2022. Methods: This was held amongst 200 healthy individuals. agglutination method used grouping, capillary tube Dukes BT. Mean times (in seconds) were compared. Results: conducted individuals (120 men, 80 women) aged 20-25 years. Although changes not statistically significant, values higher O, less type B AB grouping had lowest (p> 0.17). Women greater than men (p <0.001). There also a significant (Pearson's correlation coefficient, p = 0.512, Conclusion: analysis showed propensity jeopardy haemorrhagic conditions lesser risk thrombotic events ‘’O’’ comparison AB, or B. multicentre, bigger population an importance on determining plasma vWF levels may be useful confirming results, identifying taking preventive measures early.
