Lp-PLA2
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, Platelet-activating factor acetylhydrolase
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.
Frequently asked questions
- What is a normal Lp-PLA2 level?
- A typical reference range for Lp-PLA2 is 0–200 ng/mL (source: ABIM). Reference ranges vary by laboratory, age, and sex, so always compare against the range on your own lab report.
- What units is Lp-PLA2 measured in?
- Lp-PLA2 is most commonly reported in ng/mL. Labs in different countries may use other units — you can convert between them with BloodId's blood test unit converter.
- Where do Lp-PLA2 reference ranges come from?
- BloodId uses ABIM standard reference ranges and educational information from MedlinePlus (see our methodology). Reference ranges still vary by lab, age, and sex, so always compare against your own report.
- Can I track Lp-PLA2 over time?
- Yes. Upload results from any lab and BloodId charts your Lp-PLA2 over time against its reference range, so you can see whether the trend is rising, falling, or stable.
