Lipoprotein-associated phospholipase A2 (Lp-PLA2), also known as platelet activating factor Acetylhydrolase, is an inflammatory enzyme that circulates bound mainly to low density lipoproteins and has been found to be localized and enriched in atherosclerotic plaques. In multiple clinical trials, Lp-PLA2 activity has been shown to be an independent predictor of coronary heart disease and stroke in the general population. Measurement of Lp-PLA2 may be used along with traditional cardiovascular risk factor measures for identifying individuals at higher risk of cardiovascular disease events. Clinical management may include beginning or intensifying risk reduction strategies. The activity assay is an enzyme assay run on an automated chemistry platform.

Patient Preparation:
Fasting is preferred but not required

Process samples by removing or separating serum from red blood cells
using standard separation procedures. Recommend to centrifuge and
separate samples within four hours of venipuncture as per good
laboratory practices.
