LDL Medium measures the count of medium-sized LDL particles, a subfraction with intermediate atherogenic risk between small-dense and large-buoyant LDL.
The medium fraction contributes to cardiovascular risk proportionally to its count, though it's less atherogenic than small LDL per particle. Changes in the medium fraction alongside small-LDL shifts help track whether metabolic interventions are successfully migrating particles toward healthier sizes.
Optimal LDL Medium (ION): 0-400 nmol/L.
Typically re-tested every 12 weeks.
