Cholesterol is checked through a blood test, which generally requires fasting for 8 to 10 hours prior to the blood draw and a light diet for a week prior to the blood draw for relatively accurate results.
A morning fasting venous blood test is recommended for cholesterol levels. When checking cholesterol, it is recommended that a complete set of lipids be checked. The lipid profile can be used to determine the level of lipids in the body by using total cholesterol, triglycerides, LDL cholesterol, HDL cholesterol, and very-low-density lipoprotein (VLDL) cholesterol.
Elevated cholesterol levels are one of the major risk factors for increased mortality from coronary heart disease (CHD), therefore, effective control of cholesterol levels is important in the prevention and treatment of CHD.
If you eat high-calorie food before the blood draw, it will affect the changes of lipid cholesterol in the body to a certain extent, and in severe cases, celiac disease will occur. If abnormal cholesterol data are found in the test, further examination is recommended for a clear diagnosis and active treatment.
