Do I need a Lipoprotein (a) test?
Worried about heart disease even though your cholesterol looks normal? Could an invisible genetic risk factor be putting your heart at risk without you knowing?
Lipoprotein (a) is a unique cholesterol particle largely determined by your genes. Elevated levels significantly increase your risk of heart attack and stroke, regardless of your lifestyle.
Testing your Lp(a) gives you a vital snapshot of your inherited cardiovascular risk, empowering you to personalize prevention strategies and protect your heart health proactively. This one-time test could be the missing piece in understanding your true heart disease risk.
Get tested with Superpower
If you’ve been postponing blood testing for years or feel frustrated by doctor appointments and limited lab panels, you are not alone. Standard healthcare is often reactive, focusing on testing only after symptoms appear or leaving patients in the dark.
Superpower flips that approach. We give you full insight into your body with over 100 biomarkers, personalized action plans, long-term tracking, and answers to your questions, so you can stay ahead of any health issues.
With physician-reviewed results, CLIA-certified labs, and the option for at-home blood draws, Superpower is designed for people who want clarity, convenience, and real accountability - all in one place.
Key benefits of Lipoprotein (a) testing
- Reveals your inherited heart disease risk independent of cholesterol or lifestyle.
- Flags elevated Lp(a) that silently accelerates plaque buildup in arteries.
- Explains early heart attacks or strokes despite normal LDL cholesterol levels.
- Guides aggressive prevention strategies when levels are high (statins, aspirin, lifestyle).
- Clarifies familial risk so relatives can be screened and protected early.
- Tracks whether targeted therapies (emerging drugs) may benefit you long-term.
- Best interpreted once in adulthood; Lp(a) stays stable over time.
What is Lipoprotein (a)?
Lipoprotein (a), often written as Lp(a), is a particle in your blood that carries cholesterol and fats. It's made in the liver and looks similar to LDL cholesterol, but with an extra protein called apolipoprotein (a) attached to its surface. This extra protein makes Lp(a) unique and gives it properties that go beyond simple fat transport.
Your genes decide how much you make
Unlike other cholesterol particles, your Lp(a) level is almost entirely determined by the genes you inherit from your parents. Diet, exercise, and most medications have little effect on it. Once your liver starts producing Lp(a) at a certain level, it tends to stay stable throughout your life.
It may protect wounds but can harm arteries
Scientists believe Lp(a) originally evolved to help with wound healing and tissue repair. But when levels are elevated, Lp(a) can promote inflammation and encourage plaque buildup inside artery walls. This makes it a marker of cardiovascular risk that operates independently of traditional cholesterol measures.
Why is Lipoprotein (a) important?
Lipoprotein (a), or Lp(a), is a cholesterol-carrying particle that behaves more like a genetic fingerprint than a lifestyle marker. Unlike LDL cholesterol, which responds to diet and exercise, Lp(a) levels are largely determined at birth and remain stable throughout life. Elevated Lp(a) promotes inflammation in artery walls and accelerates plaque formation, raising the risk of heart attack and stroke independent of other cardiovascular risk factors.
Your Lp(a) level is written in your DNA
Most people have Lp(a) levels below 30 mg/dL, and lower is better. There is no "low" threshold that causes harm. Values remain consistent from childhood through adulthood, and they don't differ meaningfully between men and women outside of pregnancy, when levels may temporarily rise.
High levels silently accelerate artery damage
When Lp(a) exceeds 50 mg/dL, cardiovascular risk climbs steeply, even in people with otherwise healthy cholesterol profiles. The particle infiltrates artery walls, triggers clotting, and stiffens blood vessels. This process is silent. Most people feel nothing until a cardiac event occurs.
It connects cholesterol, clotting, and inflammation
Lp(a) links lipid metabolism to thrombosis and vascular inflammation, making it a bridge between multiple disease pathways. Elevated levels increase the likelihood of aortic valve stenosis, peripheral artery disease, and recurrent cardiovascular events. Testing once in adulthood reveals inherited risk that standard cholesterol panels miss entirely.
What do my Lipoprotein (a) results mean?
Low lipoprotein (a) levels
Low values usually reflect favorable genetic inheritance. Lipoprotein (a), or Lp(a), is a cholesterol-carrying particle whose blood concentration is largely determined at birth by your genes and remains stable throughout life. Lower levels confer less cardiovascular risk, as Lp(a) promotes both atherosclerosis and clot formation when elevated.
Optimal lipoprotein (a) levels
Being in range suggests your genetically determined Lp(a) level falls within population norms, though optimal truly means lower rather than mid-range. Many labs define normal as below 30 milligrams per deciliter or below 75 nanomoles per liter, but cardiovascular risk begins rising well before these thresholds. The lower your Lp(a), the better for long-term arterial health.
High lipoprotein (a) levels
High values usually reflect inherited genetic variants that increase production of this particle. Elevated Lp(a) independently raises risk for heart attack, stroke, and aortic valve disease by accelerating plaque buildup and enhancing blood clotting. Unlike other lipids, Lp(a) does not respond meaningfully to diet or most standard cholesterol medications.
Factors that influence lipoprotein (a)
Lp(a) levels are remarkably stable across the lifespan and unaffected by fasting, exercise, or typical lifestyle factors. Pregnancy, kidney disease, and thyroid disorders can cause modest changes. Measurement methods vary between labs, so consistency in testing platform matters when tracking over time.
