The VLDL Cholesterol test measures a specific type of "bad" cholesterol that is the primary carrier of triglycerides in your blood. High VLDL levels are strongly associated with plaque buildup in your arteries (atherosclerosis) and an increased risk of heart attack and stroke. This value is a key part of our comprehensive Lipid Profile and is essential for a complete cardiovascular risk assessment. This is a crucial, actionable number. Knowing your VLDL level gives your doctor a more targeted way to protect your arteries.
