This study aimed to evaluate the relationship between the results of blood test and Sasang constitution. We performed blood test of 2,387 university students in Health examination. Sasang constitution was diagnosed by using the Questionnaire of Sasang Constitution Class II(QSCC II). All the data were analysed statistically by descriptive statistics, ANOVA and logistic regression analysis. The Taeeumin group showed significantly higher AST, ALT, GGT, LDH, CPK, creatinine, uric acid, total cholesterol, TG, and LDL levels than other groups, while having a lower HDL level. According to logistic regression analysis, Hb, RBC, uric acid, creatinine were effective common factors for classifying each constitution groups. In the results of this study, there were significant differences in the results of blood test between the three constitutions. But the blood test was insufficient as an objective indicator for discriminating Sasang constitutions.
