Haemostasis is stoppage of bleeding from damaged blood vessels. Evaluation of haemostasis is an essential factor for surgeons and anaesthetists before undertaking any surgical procedure. Hence it is a routine pre-operative test for hospitals. The objective of the present study is to assess the distribution of blood groups and to find out if there is any relationship of gender with bleeding time and clotting time. In the present study it is found that O blood group is more prevalent in both the sexes (25% in males and 14.5% in females) than A, B and AB.Clotting time is found to be more in O and AB blood groups in females, whereas bleeding time in different blood groups did not show any change in both the sexes. https://biomedpharmajournal.org/vol7no2/gender-based-blood-group-distribution-and-its-relationship-with-bleeding-time-and-clotting-time-in-medical-students/ Blood Group Clotting time and Bleeding time
