Abstract
Serum LDL-cholesterol (LDL-C) of 929 Peoples who received a medical checkup was analyzed using the homogeneous assay method by a reagent; Cholestest LDL (Daiichi Pure Chemicals Ltd) . This system showed reliable sensitivity regarding several functional activities. Obesity, hypertension, and smoking were significantly correlated with high LDL-C value (p<0.05) . Therefore, these results suggested that (1) obesity, hypertension, and smoking are risk factors for arteriosclerosis, and (2) serum LDL-C is valuable as one of the screening methods for detection of arteriosclerosis during a medical checkup.
