It is very clear that ABO blood group system is the most clinically significant blood group system. The study was done in University Medical Centre in Southeastern part of Nigeria. A total of 200 subjects were recruited for the study comprising 5o subjects each blood group who were apparently healthy individuals drawn from the institution. About 2mls of venous blood was collected from the subjects into anticoagulant containers for haematological parameters determination. The haematological parameters were determined using Mindray BC-5300. The results were expressed as mean± standard deviation. The data were analysed with the statistical package for social science (SPSS) version 20 using t-test, ANOVA and the level of significance was set at P<0.05. The study showed significant difference (P=0.001) in WBC of Blood group O subjects compared to blood group A subjects (5.5 ±0.8 X 109/L; 4.0±0.5 X 109/L ) and no significant difference in Neutrophils (40.0±8.2%; 41.0±6.5%, P=0.562), Lymphocytes (56.0 ±6.2%; 53.0±4.7%, P=0.836), Monocytes (1.0 ±0.1%;1.0±0.1%, P= 0.952), Red blood cells(4.6±0.3 X 1012/L; 4.8±0.5 X 1012/L, P=1.000), haemoglobin (13.7±2.4 g/dl; 14.3±3.1 g/dl, P= 0.869), packed cell volume(41.0±6.4%; 43.04.6%, P= 0.752), MCV(89.1±10.6fl; 89.6±7.5fl, P=1.000) , MCH(29.8±2.3pg; 29.8±1.9pg, P=1.000) and MCHC(334.0±15.2g/l; 333.0±10.8g/l, P=0.998) respectively. The study showed significant difference (P=0.001) in WBC of Blood group O subjects compared to blood group A subjects (5.5 ±0.8 X 109/L; 2.4±0.3 X 109/L, P=0.000), Monocytes (1.0 ±0.1%;2.0±0.2%, P= 0.001), and no significant difference in Neutrophils (40.0±8.2%; 40.0±7.3%, P=1.000), Lymphocytes (56.0 ±6.2%; 58.0±5.2%, P=0.724), Red blood cells(4.6±0.3 X 1012/L; 4.6±0.2 X 1012/L, P=1.000), haemoglobin (13.7±2.4 g/dl; 13.6±2.2 g/dl, P= 0.978), packed cell volume(41.0±6.4%; 41.0±3.5%, P= 1.000), MCV(89.1±10.6fl; 89.1±8.2fl, P=1.000), MCH(29.8±2.3pg; 29.6±2.0pg, P=1.000) and MCHC(334.0±15.2g/l; 332.0±13.6g/l,
