What Does This Test Measure?

VLDL triglycerides are a component of VLDL, which carries triglycerides (a type of fat) from your liver to other parts of your body. High levels of VLDL triglycerides can contribute to elevated overall cholesterol and increase the risk of cardiovascular issues.

Why Might You Need This Test?

Your healthcare provider may order this test if you have risk factors for high cholesterol, such as a family history of heart disease, obesity, or diabetes. It may also be part of a routine lipid panel to monitor cholesterol levels.

What to Expect Before the Test

No special preparation is needed for this test. You may have a blood draw, typically from a vein in your arm, and the sample will be sent to a lab for analysis.

What Are Common Results?

Results are usually reported as a numerical value for triglycerides in VLDL, though specific reference ranges can vary by lab. Your provider will interpret the results in relation to your overall health and medical history.

Reference range

Optimal: <100 mg/dLN/A

Specimen: serum

Fasting for 12-14 hours preferred. Water is permitted. Avoid alcohol for 24 hours before the test.

Clinical interpretation

Frequently asked questions

What does a high or low VLDL triglyceride level mean?
A high VLDL triglyceride level may suggest poor lipid metabolism or increased risk for heart disease. A low level may be less concerning but could still be part of a broader lipid assessment.
How can I lower my VLDL triglyceride levels?
Lifestyle changes such as a heart-healthy diet (low in saturated fats and sugars), regular physical activity, and avoiding excessive alcohol can help lower VLDL triglycerides. Your healthcare provider may also recommend medications if needed.
Is this test the same as checking total cholesterol?
No, this test specifically measures triglycerides in VLDL particles. Total cholesterol includes triglycerides, HDL, LDL, and other fats, so it’s often measured separately as part of a comprehensive lipid profile.
