Purpose. The main purpose of blood transfusion centers is the provision appropriate blood components that the patient needs by preparing certain blood components. Therefore, the blood group is at the top among the routine work of blood transfusion centers. The present study was conducted to evaluate the distribution of blood groups in student as well as general population of different categories of Gujranwala Punjab Pakistan. Material method Study was conducted by retrospectively examining voluntary donor data sets between from January 2018 and December 2018. ABO and Rh Blood groups obtained by tube agglutination & slide agglutination methods ABO and Rh typing was done by antigen antibody agglutination test by commercially available standard anti-sera i.e. anti A, anti B and Anti D after validation at blood bank. Results Study duration is only one year this study is conducted at Sundas foundation blood bank and hematological center Gujranwala. ABO and Rh blood groups are studied, which are O, A, B, AB, the frequency for these blood groups are, respectively. O (30%), A (24%), B (35%) and AB (11%).Under Rhesus (Rh) system in which Rh –ve are (6%) and Rh + ve are (94%).. Conclusion The study has a significant implication regarding the management of blood bank and transfusion services in this area. Knowledge of blood group distribution is also important for clinical studies. Besides, these studies will help a lot in reducing the maternal mortality rate, as access to safe and sufficient supply of blood will help significantly in reducing the preventable deaths. Such studies need to be carried out at all the regional level of Pakistan. From this we concluded that the highest frequency is noted in blood group B and lowest frequency is noted in blood group AB. The totals Number of male and female donor are 2603 in which The female donors are 291. The total % of Rh+ve 94% and Rh -ve is 6%. Knowledge of the blood group distribution is also important for clinical trials to be reliable geographical information and forensic studies in the population. Such studies must be carried out on all regional levels of Pakistan. Key words; Frequency of ABO blood groups, rhesus.
