LDL Peak Size Unit Converter

LDL peak size measures the diameter of your most common LDL (low-density lipoprotein) particles. LDL particles vary in size, and this test identifies whether your predominant LDL particles are large and buoyant or small and dense.

Results are typically classified into two patterns: Pattern A (large, buoyant particles with diameter ≥25 nm or ≥220 angstroms) and Pattern B (small, dense particles with diameter ≤20.5 nm or ≤218 angstroms). Pattern B is associated with higher cardiovascular risk.

While standard lipid panels measure how much LDL cholesterol you have, LDL peak size tells you about the quality and characteristics of your LDL particles.

LDL particles are produced in the liver and formed from the metabolism of triglyceride-rich VLDL particles. The size of LDL particles is determined by triglyceride metabolism, genetic factors, and the activity of enzymes like hepatic lipase and cholesteryl ester transfer protein (CETP).
