Cardiovascular
LDL-P
LDL particle number — counts the actual number of LDL particles, regardless of the cholesterol they carry.
Optimal Range
< 1000 nmol/L (optimal) · < 1300 nmol/L (normal)
Why It Matters
Two people with the same LDL-C can have vastly different particle counts. Higher particle numbers mean more chances for arterial wall penetration, making LDL-P a better risk discriminator than LDL-C alone.
