LDL Particle Size Analysis
LDL particle size analysis characterizes whether LDL in blood is mainly large buoyant (Pattern A) or small dense (Pattern B). Small dense LDL is more atherogenic because it penetrates the arterial wall more easily and oxidizes faster, and it often accompanies high triglycerides, low HDL, and insulin resistance. Knowing particle size helps refine cardiovascular risk.

What is LDL Particle Size Analysis?
LDL particle size analysis characterizes whether LDL in blood is mainly large buoyant (Pattern A) or small dense (Pattern B). Small dense LDL is more atherogenic because it penetrates the arterial wall more easily and oxidizes faster, and it often accompanies high triglycerides, low HDL, and insulin resistance. Knowing particle size helps refine cardiovascular risk.
Why It Matters
Small dense LDL more atherogenic than large buoyant particles. Pattern B (small particles) increases cardiovascular risk independent of LDL-C.
