Lipoprotein-Associated Phospholipase A2 (PLAC) Blood Test

Order a lipoprotein-associated phospholipase A2 (PLAC) blood test to measure an enzyme in a blood sample. The PLAC Test is a blood test that measures an enzyme associated with the inflammation of your arteries. Having increased levels of Lp-PLA2 increase your risk of having a heart attack or stroke. In many adults, cholesterol causes a fatty deposit called plaque to build up in the arteries walls. Once arterial walls become inflamed, your body produces the enzyme Lp-PLA2. When the amount of Lp-PLA2 is high, this can indicate that the plaque is more likely to rupture through the inside lining of your artery into your bloodstream, where it may cause a clot that could result in a heart attack or stroke.
