LDL-P

Meaning

LDL-P, or Low-Density Lipoprotein Particle Number, is a sophisticated clinical biomarker that quantifies the total number of atherogenic low-density lipoprotein particles circulating in the bloodstream. Unlike the traditional LDL-C metric, which measures the mass of cholesterol within the particles, LDL-P measures the count of the particles themselves. This distinction is clinically significant because the particle number, rather than the cholesterol mass, is considered a more accurate predictor of cardiovascular risk, especially in cases of metabolic syndrome or insulin resistance.
