Current research suggests an important relationship between apolipoprotein serum concentrations and risk factors for athlerosclerosis. Apolipoproteins Apo A1 and Apo B 100 serum levels along with traditional lipid serum screening (cholesterol) are of primary focus when accessing cardiac health. Various isoforms of Apolipoproteins are also suggestive for renal impairment, Alzheimer’s disease, and vascular disease development. AlerCHEK, Inc. provides highly sensitive ELISA tests for the quantitation of serum Apolipoprotein A1 and Apolipoprotein B-48/100 levels as well as Lp(a) and C-Reactive Protein serum levels.
