What is LDL Size?
LDL particle size refers to the physical diameter of low-density lipoprotein particles in your blood. LDL particles exist in a range of sizes, typically classified as large and buoyant (Pattern A) or small and dense (Pattern B).
Large LDL particles typically measure greater than 25.5 nm in diameter, while small dense LDL particles are smaller than 25.5 nm. The size and density of your LDL particles can affect how they interact with your arterial walls.
This measurement provides additional information beyond standard LDL cholesterol levels and may help refine cardiovascular risk assessment in certain individuals.
Where Does LDL Size Come From?
LDL particles are formed in the bloodstream from very-low-density lipoproteins (VLDL) produced by the liver. The size of LDL particles is determined by the triglyceride content of precursor VLDL particles and the activity of enzymes such as hepatic lipase and cholesteryl ester transfer protein (CETP).
