LDL-P (LDL Particle Number)
LDL-P counts the total number of LDL particles in blood using NMR spectroscopy and is independent of the cholesterol carried by each particle. Because each LDL particle can enter the arterial wall, LDL-P often predicts cardiovascular events better than LDL-C, especially when the two are discordant. It is useful for refining risk in metabolic syndrome and insulin resistance.

What is LDL-P (LDL Particle Number)?
LDL-P counts the total number of LDL particles in blood using NMR spectroscopy and is independent of the cholesterol carried by each particle. Because each LDL particle can enter the arterial wall, LDL-P often predicts cardiovascular events better than LDL-C, especially when the two are discordant. It is useful for refining risk in metabolic syndrome and insulin resistance.
Why It Matters
More predictive of cardiovascular events than LDL cholesterol. Particle number matters more than cholesterol content. Guides aggressive lipid therapy.
