LDL Subfractions Test

$299.00

This test breaks down your LDL (“bad”) cholesterol into its different particle sizes and types, giving a deeper insight into your heart health than a standard cholesterol test. Small, dense LDL particles are more likely to penetrate artery walls and contribute to plaque buildup, while larger, buoyant LDL particles are considered less harmful. By measuring the number and size of LDL subfractions, this test helps identify hidden cardiovascular risk — even if your overall LDL cholesterol appears normal. It’s especially useful for people with diabetes, metabolic syndrome, or a family history of heart disease.

Why choose this test?

This test breaks down your LDL (“bad”) cholesterol into its different particle sizes and types, giving a deeper insight into your heart health than a standard cholesterol test. Small, dense LDL particles are more likely to penetrate artery walls and contribute to plaque buildup, while larger, buoyant LDL particles are considered less harmful.

About these tests

The LDL Subfractions Test provides a detailed analysis of your low-density lipoprotein (LDL) particles — the “bad” cholesterol that can build up in your arteries. Unlike a standard cholesterol test, which only measures total LDL cholesterol, this test separates LDL into its individual particle sizes and densities. Smaller, denser LDL particles are more likely to cause arterial plaque and increase the risk of heart disease, while larger LDL particles are less harmful. Understanding your LDL particle pattern helps uncover hidden cardiovascular risks that may be missed by routine lipid testing and can guide more targeted treatment or lifestyle changes.
