Lipoprotein(a) Blood Test (Lp(a))

Lipoprotein(a), commonly abbreviated as Lp(a), is a genetically determined lipoprotein particle that circulates in the blood and contributes to cardiovascular risk. Unlike LDL cholesterol, Lp(a) levels are largely fixed by your genes and remain relatively stable throughout life, so a single measurement can provide lifelong insight. This test is suitable for adults who have a personal or family history of premature cardiovascular disease, those with elevated LDL cholesterol despite lifestyle measures, and anyone seeking a more complete picture of their inherited heart risk.

The test measures the concentration of Lp(a) in a simple blood sample. Elevated Lp(a) is recognised as an independent risk factor for atherosclerosis, heart attack, stroke, and aortic valve disease. Because standard lipid profiles do not include Lp(a), this test adds information that can help you and your doctor refine your overall cardiovascular risk assessment and decide whether more intensive risk management is appropriate.

Why it matters

Lp(a) is not routinely measured in standard cholesterol checks, yet it can be a major hidden contributor to heart disease. Knowing your Lp(a) level allows you and your clinician to identify an inherited risk that might otherwise go unnoticed, enabling earlier and more personalised cardiovascular risk management.
