Celebrating Lp(a) Awareness Day 2022 today!
Randox are raising awareness for Lipoprotein(a), we want to drive awareness on tests that are available to you to decrease the risk of stroke, heart attack or other heart diseases.
Lp(a) is a risk factor for atherosclerosis and related diseases including CHD and stroke. It is increasingly recognised as the strongest known genetic risk factor for premature coronary artery disease. The biggest challenge that exists surrounding Lp(a) measurement is the heterogeneity of the apolipoprotein(a) isoforms, resulting in the underestimation or overestimation of Lp(a) concentrations.
Benefits of the Randox Lp(a) assay
WHO/IFCC reference material – The Randox Lp(a) assay is calibrated in nmol/l and traceable to the WHO/IFCC reference material (IFCC SRM 2B) and provides an acceptable bias compared with the Northwest Lipid Metabolism Diabetes Research Laboratory (NLMDRKL) gold standard method.
Dedicated calibrator & control available – Five point calibrator with accuracy-based assigned target values (in nmol/l) is available, accurately reflecting the heterogeneity of the apo(a) isoforms. Dedicated Lp(a) control is available offering a complete testing package.
Excellent correlation – A correlation coefficient of r=0.995 was displayed when the Randox method was compared against other commercially available methods.
Excellent precision – The Randox Lp(a) assay displayed a within run precision of <2.54%.
Liquid ready-to-use – The Randox Lp(a) assay is available in a liquid ready-to-use format for convenience and ease-of-use.
Applications available – Instrument-specific settings can be provided for a wide range of clinical chemistry analysers.
The biggest challenge that exists surrounding Lp(a) measurement is the heterogeneity of the apo(a) isoforms, resulting in the underestimation or overestimation of Lp(a) concentrations. In immunoassays, the variable numbers of repeated KIV-2 units in Lp(a) act as multiple epitopes. This is where standardisation across calibrators is vital. Unless the calibrants do have the same range of isoforms as test samples, those with higher numbers of the KIV-2 repeat, will represent with an overestimation in Lp(a) concentrations and those with smaller numbers of the KIV-2 repeat, will represent with an underestimation. The smaller isoforms are strongly associated with higher Lp(a) concentrations. Lack of standardisation of the calibrant would result in an underestimation of Lp(a) associated CVD risk. It is important to note that an Lp(a) immunoassay employing isoform insensitive antibodies does not exist.
DID YOU KNOW?
Lp(a) has been identified to be a key risk factor for cardiovascular complications in individuals with COVID-19!
It is well documented that pre-existing comorbidities such as diabetes and CVD are associated with greater severity and higher fatality rates in those with COVID-19. Those with either baseline elevated Lp(a) or those whose Lp(a) levels increased following infection from COVID-19, or both, maybe at a significantly increased risk of developing thromboses. Elevated Lp(a) levels may cause acute destabilisation of pre-existing but quiescent, atherosclerotic plaques, which could induce an acute myocardial infarction or stroke.
Identifying any possible health conditions that would relate to early signs of stroke, heart attack or other heart diseases will allow you to make any decisions on an appropriate diet, lifestyle changes and early treatment to reduce your risk of further problems.
