VLDL测试

定义

VLDL stands for very low density lipoprotein. Lipoproteins are made up of 胆固醇, triglycerides, and proteins. They move 胆固醇, triglycerides, and other lipids (fats) around the body.

VLDL is one of the three main types of lipoproteins. VLDL contains the highest amount of triglycerides. VLDL is a type of "bad 胆固醇" because it helps 胆固醇 build up on the walls of arteries.

A lab test is used to measure the amount of VLDL in your blood.

选择的名字

Very low density lipoprotein test

How the Test is Performed

A blood sample is needed. Most of the time blood is 从静脉中抽出 located on the inside of the elbow or the back of the hand.

How the Test will Feel

You may feel slight pain or a sting when the needle is inserted. You may also feel some throbbing at the site after the blood is drawn.

Why the Test is Performed

You may have this test to help assess your risk for heart disease. Increased levels of VLDL are linked to 动脉粥样硬化. This condition can lead to coronary heart disease.

This test may be included in a coronary risk profile.

正常的结果

Normal VLDL 胆固醇 level is between 2 and 30 mg/dL.

Normal value ranges may vary slightly among different laboratories. Talk to your doctor about the meaning of your specific test results.

The examples above show the common measurements for results for these tests. Some laboratories use different measurements or may test different specimens.

What Abnormal Results Mean

A high VLDL 胆固醇 level may be associated with a higher risk for heart disease and stroke. However, VLDL 胆固醇 level is rarely targeted when treatment for high 胆固醇 is done. 相反, LDL 胆固醇 level is more often the main target of therapy.

风险

Veins and arteries vary in size from one person to another and from one side of the body to the other. Obtaining a blood sample from some people may be more difficult than from others.

The risks associated with having blood drawn are slight, but may include:

• 大出血
• Fainting or feeling lightheaded
• Hematoma (blood accumulating under the skin)
• Infection (a slight risk any time the skin is broken)

注意事项

There is no direct way of measuring VLDL. Most labs estimate your VLDL based on your triglycerides level. It is about one fifth of your triglycerides level. This estimate is less accurate if your triglycerides level is above 400 mg/dL.
