About the PLAC® Test for Lp-PLA2 Activity

The PLAC® Test for Lp-PLA2 Activity, cleared by the U.S. FDA in December 2014, is to be used in conjunction with clinical evaluation and patient risk assessment as an aid in predicting risk of coronary heart disease (CHD) in patients with no prior history of cardiovascular events, which represents approximately 75% of the U.S. population. Lp-PLA2 (lipoprotein-associated phospholipase A2) is a cardiovascular risk marker supported by a decade of peer-reviewed literature. Lp-PLA2 provides important new information about blood vessel inflammation, over and above the traditional risk factors measured on a lipid panel.
