Blood types are inherited & represent contribution from both parents. Any one with antigen A in all his RBCs is classified as belonging to blood group A. Those with agglutinogen B is classified as type B. While those with A & B antigens belong to group AB. However, those with neither A nor B are belong to group O. The aim of the study is to determine the physiological & epidemiological characteristics & distribution of ABO blood group in blood donors & recipient in Tikrit city. A total of 4309 subjects were investigated in this study. 2411 blood donors (2357 men & 54 women) & 1898 blood recipient patients (759 men & 1139 women).

The highest frequency of blood group in blood donors subjects was blood group 0+ (41.5%) & the lowest frequency of blood group was blood group AB- (0.29%). Also, the highest frequency of blood group in blood recipient subjects was blood group 0+, (35.8%), and the lowest frequency of blood group was blood group AB- (l%)
