LDL-P details

LDL particle number (LDL-P) counts the actual number of LDL ('bad' cholesterol) particles in your blood, rather than measuring the total amount of cholesterol they're carrying, which is what a standard LDL cholesterol test does. Because each LDL particle carries some risk of contributing to artery plaque regardless of how much cholesterol it happens to be carrying, particle number is considered by many experts to be a more accurate cardiovascular risk marker than LDL cholesterol alone — particularly useful when the two numbers don't agree, which can happen with insulin resistance, diabetes, or metabolic syndrome, where particles tend to be smaller and more numerous relative to their cholesterol content.
