OxLDL
Also known as: Oxidized low-density lipoprotein, Oxidized LDL
Use
OxLDL (“oxidized LDL”) measures damage of the ApoB protein subunit on the surface of LDL due to oxidative modification. Oxidation of ApoB is an initiating factor in macrophage recruitment, foam cell formation, and vascular inflammation within the arterial wall. Elevated OxLDL levels indicate a 4.3× increased risk of having a coronary heart disease (CHD) event and a 3.5× increased risk of developing metabolic syndrome (MetS).
