Lp-PLA2 (lipoprotein-associated phospholipase A2) is an enzyme associated with vascular inflammation. It is produced by inflammatory cells and is a marker of arterial plaque instability.
Category: lipids
Also known as: lp-pla2, lp pla2, lipoprotein-associated phospholipase a2, plac test
Reference range: 0–200 ng/mL (Source: ABIM)
Standard unit: ng/mL
High values may indicate
High Lp-PLA2 levels may indicate increased risk of coronary heart disease, stroke, and unstable arterial plaques prone to rupture.
Low values may indicate
Low Lp-PLA2 levels are generally favorable and suggest lower vascular inflammation and reduced cardiovascular risk.
