VLDL test

• Alternative Names

  Very low density lipoprotein test

• How the test is performed

  Blood is drawn from a vein, usually from the inside of the elbow or the back of the hand. The site is cleaned with germ-killing medicine (antiseptic). The health care provider wraps an elastic band around the upper arm to apply pressure to the area and make the vein swell with blood.

  Next, the health care provider gently inserts a needle into the vein. The blood collects into an airtight vial or tube attached to the needle. The elastic band is removed from your arm.

  Once the blood has been collected, the needle is removed, and the puncture site is covered to stop any bleeding.

  In infants or young children, a sharp tool called a lancet may be used to puncture the skin and make it bleed. The blood collects into a small glass tube called a pipette, or onto a slide or test strip. A bandage may be placed over the area if there is any bleeding.

• How the test will feel

  When the needle is inserted to draw blood, some people feel moderate pain, while others feel only a prick or stinging sensation. Afterward, there may be some throbbing.

• Why the test is performed

  Your doctor may order this test to determine your risk of heart disease. Increased levels of VLDL are linked to atherosclerosis, which can lead to coronary heart disease.

  This test may be included in a coronary risk profile.

• Normal Values

  Normal VLDL cholesterol level is between 5 and 40 mg/dL.

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

• What abnormal results mean

  High levels may be associated with a higher risk for heart disease and stroke.

• What the risks are

  There is very little risk involved with having your blood taken. Veins and arteries vary in size from one patient to another and from one side of the body to the other. Taking blood from some people may be more difficult than from others.

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

  • Excessive bleeding
  • Fainting or feeling light-headed
  • Hematoma (blood accumulating under the skin)
  • Infection (a slight risk any time the skin is broken)
• Special considerations

  There is no simple, direct way of measuring VLDL. Most labs estimate your VLDL based on your triglyceride level. It is approximately one fifth of your triglycerides level, although this is less accurate if your triglyceride level is above 400 mg/dL.
