The PLAC^® Test 

diaDexus has received FDA clearance to market the PLAC Test as an aid in the prediction of risk for coronary heart disease (CHD) and ischemic stroke associated with atherosclerosis. The PLAC Test determines levels of Lp-PLA₂ (lipoprotein-associated phospholipase A₂) in the blood; individuals with elevated levels of Lp-PLA₂ have been shown to have an increased risk of ischemic stroke and coronary heart disease.
