This test looks for a specific lipoprotein, Lp-PLA2, in your blood. The test is used to help predict your risk for cardiovascular disease and stroke.

Lipids are fats in your blood. Lipoproteins are combinations of fats and proteins that carry the fats in your bloodstream. If you have Lp-PLA2 in your blood, you may have fatty deposits in your arteries that are at risk of rupturing and causing heart disease or stroke.
