Blood group, bleeding time and clotting time play very important role before any surgical procedure. ABO blood group system is an important factor in the field of transfusion medicine. The study was aimed to observe the abundance of specific ABO blood groups and its coordination with bleeding and clotting time of individuals of different ethnicity in Quetta, Balochistan, and also some other variables were taken under consideration such as gender, age, weight and blood pressure. Blood group was determined by antisera, bleeding time by duke’s filter paper method and clotting time by Wright’s capillary tube method. Chi-square test was applied and the P value of <0.05 was taken as statistically significant. As a result of study, B blood group was found to be most common whereas AB was least common and they had no significance with bleeding time and clotting time but bleeding time was observed to be significant with ethnicity and clotting time significant with ethnicity and gender. Bleeding time had negative correlation with clotting time, age, weight and systolic blood pressure. While clotting time had positive correlation with age and weight but it was also negatively correlated with systolic blood pressure. Finally, no exact abundance of ABO blood groups occurred based on four mentioned ethnic groups but bleeding time and clotting time differ among them and also bleeding time and clotting time increase with decreasing age. Females and low aged individuals lie in the normal range of blood pressure as compared to males and high aged individuals.
