Correlation of blood groups, Bleeding time and Clotting time in male and female students; an observational study

Stoppage of bleeding from damaged blood vessels is hemostasis, an essential factor to be checked before any surgical process. Hence blood test is a routine test for hospital prior to surgeries. The study was aimed to assess the distribution of blood groups and to check gender-based relationship among the blood groups, bleeding and clotting time. The study was conducted in the department of pharmacy, BZU. The available data of 122 students of 1st year of Pharm. D was analysed in every required aspects i.e. sex, age, ABO and Rh blood groups, bleeding and clotting times. The standard antisera (A, B, & D) were used to determine the blood group, Duke Method and Capillary tube method were used to find out bleeding and clotting time respectively. Finally, all the parameters were compared and analysed statistically. In the present study, it is found that B blood group is more prevalent in both the sexes than O, A and AB. Clotting time is found to be significantly higher in O and B blood groups in females and males respectively, whereas Bleeding time was found to be greater than others in AB blood group in females and ‘O' blood group in males but the values are not significantly different from each other. In females, the values of bleeding and clotting time are slightly greater than in males, may be because of hormonal differences. Various cardiovascular and gastrointestinal diseases are associated with the blood groups, so people can take preventive measures according to their blood groups.
