The coagulation factor activity compared two groups of the lower 10% (29.1∼30.9 sec) and the upper 10% (38.0∼41.9 sec) of the normal reference range of aPTT. The aim of this study was to investigate the influence of sex, age, and ABO blood type on coagulation factor activity. There was significant difference in the activity of the coagulation factor assay based on age. The VIII (p<0.0001) and IX (p=0.0050) in the lower group of samples from those over sixty years of age is higher than from those under sixty. In contrast, XII (p=0.0285) for samples over sixty was lower than for samples under sixty. While in the upper group V (p=0.0219), VIII (p=0.0005), and IX (p=0.0014) for samples from the over sixty group was higher than those under sixty. In the case of activity of coagulation factor between O and non-O blood type, VIII (p<0.001) activity of the non-O blood type was higher than that of the O blood type in the both groups. The XII (p=0.016) activity of non-O blood type was lower than that of O blood type in the upper group. According to the multiple logistic regression analysis, when other variables are under the same conditions between lower and upper groups, there is a strong possibility for the lower group when activity of V (p=0.001), VIII (p<0.001), X (p<0.001) and XII (p<0.001) is increased. Furthermore, there is also a strong possibility of upper group when activity of II (p=0.004) and IX (p=0.012) is increased. However, no significant difference in between sex, age and XI was observed.
