It is also called a low-density lipoprotein cholesterol test.

This test measures the amount of very low-density lipoprotein (VLDL) in your blood.

VLDL cholesterol is a type of blood fat. It's considered one of the "bad" forms of cholesterol, along with LDL cholesterol and triglycerides. This is because high levels of cholesterol can clog your arteries and lead to a heart attack. Sixty percent of a VLDL particle is a triglyceride.

This test is often used along with a series of other tests in a general lipid profile to screen for cardiovascular disease (CVD). High levels of VLDL cholesterol and triglycerides in your blood may mean you are at risk for CVD. People who have obesity also have higher levels of VLDL cholesterol.

You may need this test if you are at risk for CVD. Risk factors for CVD include:

• Older age.
• Being biologically male.
• Family history.
• High blood pressure.
• Having obesity or being overweight.
• Sedentary lifestyle.
• Diabetes.

You may also need these other tests at the same time to check your cholesterol levels:

• Total cholesterol
• LDL (bad) cholesterol
• HDL (good) cholesterol
• Triglycerides

You may also need these tests:

• Coronary artery calcium scan (CAC scan)
• Electrocardiogram
• Stress test
• Echocardiogram
• Cardiac catheterization

Test results may vary depending on your age, sex, health history, and other things. Your test results may be different depending on the lab used. They may not mean you have a problem. Ask your doctor what your test results mean for you.

Results are given in milligrams per deciliter (mg/dL). Normal levels of VLDL are less than or equal to 30 mg/dL. If you have higher levels of VLDL cholesterol, you may have CVD.

The test is done with a blood sample. A needle is used to draw blood from a vein in your arm or hand.

Having a blood test with a needle carries some risks. These include bleeding, infection, bruising, and feeling lightheaded. When the needle pricks your arm or hand, you may feel a slight sting or pain. Afterward, the site may be sore.

No other factors affect your test results.

You may need to fast for 9 to 12 hours before this test. Be sure your doctor knows about all medicines, herbs, vitamins, and supplements you are taking. This includes medicines that don't need a prescription and any drugs you may use.
