Lipoprotein-Associated Phospholipase A2(Lp-PLA2) Determination Kit (Fluorescence Immunochromatographic Assay) is an in vitro diagnostic test kit. Lp-PLA2 is a calcium-independent phospholipase A2 enzyme that is associated with both low-density lipoprotein (LDL) and, to a lesser extent, high-density lipoprotein (HDL) in human plasma and serum. Lp-PLA2 activity 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.
