B-300 Validation of the Lp(a) Ultra Assay on Beckman Coulter AU680: Overcoming Isoform Heterogeneity Challenges in Lipoprotein(a) Measurement
Lipoprotein(a) [Lp(a)] is an established independent risk factor for atherosclerotic cardiovascular disease (ASCVD). Accurate quantification of Lp(a) is historically challenged by the size heterogeneity of apolipoprotein(a) isoforms, which range from 275 to 800 kDa. Traditional mass-based measurements (mg/dL) suf...
