Testing for apolipoprotein(a) phenotype using isoelectric focusing and immunoblotting technique.

Increased levels of lipoprotein(a) are known as an independent risk factor for atherosclerosis, heart disease, and stroke in man. Even in children it could show that elevated levels of Lp(a) are an independent thromboembolic risk factor. Levels of Lp(a) are influenced by several factors like nutrition, kidney or liver function, or acute-phase reaction.

Testing for lipoprotein(a) concentration and apolipoprotein(a) phenotypes: method standardization and pediatric reference values.

Increased levels of lipoprotein(a) (Lp[a])are known independent risk factor for atherosclerosis, heart disease, and stroke in adults. Even in children it could be shown that elevated levels of Lp(a) are an independent risk factor for symptomatic thromboembolism. The aim of this work was to describe the methods used for evaluating Lp(a) phenotypes, to link them to Lp(a) plasma concentrations, and to establish age-dependent reference values in children.
