FAQ
Frequently Asked Questions
No, they are different particles. Lipoprotein(a) is structurally similar to LDL but has an additional protein called apolipoprotein(a) attached, which gives it distinct properties.
Lipoprotein(a) levels are largely genetically determined and are not significantly influenced by typical lifestyle changes like diet or standard exercise. Specific medications are being developed to lower it.
It is usually measured once in a lifetime as levels are genetically stable, unless monitoring the effect of a specific treatment. It may be tested if there is a personal or strong family history of premature cardiovascular disease.
Levels above 50 mg/dL (or approximately 125 nmol/L, depending on the assay) are generally considered to confer an increased cardiovascular risk.
