Hello! Welcome to Beijing Hospital of Integrated Traditional Chinese and Western Medicine!
With the improvement of people's living standards, more and more people have elevated blood lipids or suffer from hyperlipidemia. To understand their own blood lipids, blood lipids must be tested. At present, it is medically advocated that people over the age of 20 should check their blood lipids every 2 years; people over the age of 40 should check their blood lipids at least once a year; they have a family history of heart disease, obesity, long-term excessive sugar consumption, smoking, and alcoholism, People who are used to sitting quietly, life is irregular, emotional, and are often in a state of tension, especially those who have already suffered from cardiovascular and cerebrovascular diseases, such as coronary heart disease, hypertension, diabetes, cerebral infarction and patients with hyperlipidemia, or friends with xanthoma on the skin, blood lipids should be checked regularly under the guidance of a doctor.
According to the diagnostic criteria formulated by our country in 1997, the total cholesterol (TC) per liter of blood exceeds 5.7 mmol, which is an increase in cholesterol level. Triglyceride (TG) exceeding 1.7mmol (I .e.> 1.7mmol/L) is an increase in triglyceride level. High density lipoprotein cholesterol (HDL-C) less than 0.91mmol (I .e. <0.91mmol/L,<35mg/dL) per liter of blood is also dyslipidemia. Since this standard is more suitable for China's national conditions, it has been widely adopted in China. However, medical experts at home and abroad generally agree that the ideal blood cholesterol level for each person should be less than 5.2mmol/L (I. e. <5.2mmol/L).
Blood lipids will fluctuate under the influence of various factors, so the following questions should be paid attention to before the examination:
1. When testing fasting blood lipids, be sure to extract venous blood on an empty stomach for more than 12 hours. Fasting after 8 o'clock in the evening the day before the examination can not help but water.
2. Before blood collection, the original regular diet should be maintained and the weight should be kept constant. Do not attend a banquet or have a midnight snack the night before the examination.
3. Tests should be carried out when the physiological and pathological conditions are relatively stable, and there should be no acute attack within 4-6 weeks.
4. Do not take drugs that can affect the blood lipid level and lead to the error of the test, such as contraceptives, some blood pressure lowering drugs, etc.
5. The night before the inspection to ensure a good rest, to avoid staying up late and other factors affecting the inspection results.
Blood lipid examination is easily affected by many factors. Please pay attention to the above-mentioned conditions before you go to the hospital for laboratory tests to ensure that the test results are as accurate as possible.
