The seven items of blood lipids include total cholesterol (TC), triglycerides (TG), etc. The reference values are total cholesterol (TC) for adults: 2.9-6.0mmol/L, and 3.1-5.2mmol/L for children. 1. Total cholesterol (TC): the sum of all cholesterol in the serum, the reference value is 2.9-6.0mmol/L for adults and 3.1-5.2mmol/L for children. 2. Triglyceride (TG): a kind of blood lipid, the reference value is 0.45～1.69mmol/L. 3. High-density lipoprotein cholesterol (HDL-C): a kind of lipoprotein, the reference value is >1.04mmol/L (>40mg/dL). 4. Low-density lipoprotein cholesterol (LDL-C): a kind of lipoprotein, the reference value is 2.07~3.37mmol/L (80~130mg/d). 5. Lipoprotein (a): the reference value is 10-140mmol/L (0-300mg/L). 6. apolipoprotein A1 (apoA1): reference value for men: 0.96-1.76g/L, women: 1.03-2.03g/L. 7. apolipoprotein B (apoB): reference value for men: 0.43-1.28g/L, women: 0.42-1.12g/L. After testing the seven items of blood lipids, it is necessary to consult a doctor in time for diagnosis by a specialized doctor.
