LDL Peak Size
LDL peak size reports the diameter of the most common LDL particle in a sample, measured in angstroms. A peak size above roughly 263 Å indicates predominantly large buoyant LDL (Pattern A, lower risk), while smaller peak sizes signify small dense LDL (Pattern B, higher risk). It refines cardiovascular risk beyond standard LDL cholesterol.

What is LDL Peak Size?
LDL peak size reports the diameter of the most common LDL particle in a sample, measured in angstroms. A peak size above roughly 263 Å indicates predominantly large buoyant LDL (Pattern A, lower risk), while smaller peak sizes signify small dense LDL (Pattern B, higher risk). It refines cardiovascular risk beyond standard LDL cholesterol.
Why It Matters
Larger peak size (>263 Å) indicates predominantly large buoyant LDL (Pattern A, lower risk). Smaller peak size indicates small dense LDL (Pattern B, higher risk). Useful for advanced cardiovascular risk stratification.
