VLDL stands for very low density lipoprotein. Lipoproteins are made up of cholesterol, triglycerides, and proteins. They move cholesterol, triglycerides, and other lipids (fats) to around the body.
There are three main types of lipoproteins. VLDL contains the highest amount of triglycerides. VLDL is a type of "bad cholesterol" because it helps cholesterol build up on the walls of arteries.
A lab test is used to measure the amount of VLDL in your blood.
Very low density lipoprotein test
How the Test is Performed
A blood sample is needed. Most of the time blood is drawn from a vein 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
This test may be included in a coronary risk profile.
Normal VLDL cholesterol level is between 2 and 30 mg/dL.
Note: 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
High levels may be associated linked to a higher risk for heart disease and stroke.
There is no direct way of measuring VLDL. Most labs estimate your VLDL based on your triglyceride level. It is about one fifth of your triglycerides level. This estimate is less accurate if your triglyceride level is above 400 mg/dL.
