Serum total cholesterol of 5.82 mmol/L is slightly elevated. The normal range of serum total cholesterol should be less than 5.20mmol/L. Total cholesterol is the sum of cholesterol loaded by all lipoproteins in the blood, including free cholesterol and total cholesterol esters, and the liver is the main organ for synthesizing and storing cholesterol. Hypercholesterolemia is one of the major risk factors for coronary heart disease, and the results of a large number of studies at home and abroad indicate that elevated cholesterol is closely related to atherosclerotic disease. If you have high serum total cholesterol, you need to go to the hospital and be evaluated by the doctor in conjunction with your past history, and actively receive lipid-regulating treatment.
