APOA1 and cardiovascular disorder: The National Heart Blood and Lung Institute Working Group on Future Research Directions on Lipoprotein(a) and Cardiovascular Disease therefore recently recommended the development of a standardized measurement of Lp(a), in which apo(a) values should be quantified in nmol/L.41 Here too, MS seems to be an excellent technology to achieve this, as selection of a non-kringle IV-2 peptide would allow for quantitation of apo(a) at the molar level.
