You should not eat a lot of high-fat meat a few days before the blood lipid check. Three days before the blood lipid check should try to avoid high fat diet, if the blood is drawn before the input of excessive high fat, high cholesterol and high sugar food, the blood test results can not reflect the normal level of the body. Fatty meat contains a large amount of triglycerides and cholesterol, if patients eat meat before the blood test, cholesterol and proteins in the body are difficult to be metabolized in a timely manner, which will easily lead to high blood lipids, affecting the test results and interfering with the doctor’s normal diagnosis. It is recommended that patients should not consume too much high-fat food and drink too much alcohol 3 days before the blood lipid test, maintain their usual dietary habits the day before the blood draw, avoid strenuous exercise, and preferably fast for 10~12 hours before taking the venous blood for the test. If you find any abnormality after the test, please consult your doctor in time and take relevant treatment under the doctor’s guidance.
