Characterization of PLAC® tests in the quantization of lipoprotein associated phospholipase A2 for assessment of cardiovascular diseases

Both PLAC® mass and PLAC® activity tests are effective but the CHAPS modified PLAC® mass test has no or less utility in the risk assessment of CVD. The ratio of Lp-PLA2 by either PLAC® mass or PLAC® activity over ApoA1 or (Apo A1 + Apo B) synergistically enhance the risk assessment power for ischemic stroke.
