Do I need a Lp(a) test?

Worried about heart disease running in your family, or wondering why your cholesterol stays high despite doing everything right?

Lp(a) is a genetic cholesterol particle that significantly raises your risk for heart attack and stroke. Unlike other cholesterol types, diet and exercise won't lower it.

Testing your Lp(a) gives you a vital snapshot of your inherited heart risk, empowering you to personalize prevention strategies with your doctor and address those family history concerns head-on. Knowledge is power.

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 Lp(a) testing

  • Reveals your inherited heart disease risk that diet and exercise can't change.
  • Flags elevated cardiovascular risk even when standard cholesterol levels look normal.
  • Guides aggressive prevention strategies if Lp(a) is high: statins, aspirin, or newer therapies.
  • Explains early heart attacks or strokes in families with no obvious risk factors.
  • Identifies candidates for emerging Lp(a)-lowering treatments now entering clinical use.
  • Protects relatives by prompting family screening when elevated levels are found.
  • Measured once in adulthood; levels stay stable and don't require repeat testing.

What is Lp(a)?

Lipoprotein(a), or Lp(a), is a particle in your blood that carries cholesterol and fats. It's made in the liver and consists of an LDL cholesterol core attached to a unique protein called apolipoprotein(a). Unlike other cholesterol carriers, your Lp(a) level is largely determined by your genes and stays relatively stable throughout life.

A cholesterol particle with a sticky personality

Lp(a) behaves differently from standard LDL cholesterol. Its structure allows it to promote inflammation and encourage clot formation in blood vessel walls. This makes it particularly prone to contributing to plaque buildup in arteries.

Your genes write the script

Because Lp(a) levels are inherited, they don't respond much to diet, exercise, or most cholesterol medications. Some people naturally produce very little, while others make high amounts from birth.

A hidden driver of heart risk

Elevated Lp(a) is an independent risk factor for heart disease and stroke, even when other cholesterol numbers look normal. It represents a distinct cardiovascular threat that standard lipid panels don't always capture.

Why is Lp(a) important?

Lipoprotein(a), or Lp(a), is a cholesterol-carrying particle that behaves differently from standard LDL cholesterol because it also promotes inflammation and blood clotting. Your Lp(a) level is largely determined by genetics and remains stable throughout life, making it an independent risk factor for heart attack, stroke, and aortic valve disease. Unlike other lipids, it doesn't respond much to diet or most medications, so knowing your level helps identify inherited cardiovascular risk that standard cholesterol panels miss.

When Lp(a) stays in the safe zone

Values below 30 mg/dL (or 75 nmol/L) are considered low risk and reflect a genetic advantage. People in this range face no added cardiovascular threat from Lp(a) itself. There are no symptoms associated with low levels, and no organ systems are negatively affected.

When Lp(a) climbs into the danger zone

Elevated Lp(a) - above 50 mg/dL or 125 nmol/L - significantly raises the risk of early heart disease, stroke, and calcific aortic stenosis, even when other cholesterol numbers look normal. High levels accelerate plaque buildup in arteries and increase clot formation. Women may face heightened risk during and after menopause when estrogen's protective effects wane.

The long view on inherited cardiovascular risk

Because Lp(a) is genetically fixed, a single measurement informs lifelong risk stratification. It connects lipid metabolism, inflammation, and thrombosis into one marker, guiding decisions about imaging, family screening, and intensity of preventive care across decades.

What do my Lp(a) results mean?

Low Lp(a) levels

Low values usually reflect favorable genetic inheritance. Lipoprotein(a) is largely determined by the LPA gene, and lower concentrations indicate reduced baseline cardiovascular risk related to this specific particle. There is no known physiological disadvantage to having low Lp(a), and no threshold below which harm occurs.

Optimal Lp(a) levels

Being in range suggests your genetically determined Lp(a) level does not add significant cardiovascular risk. Most guidelines consider values below 30 mg/dL or 75 nmol/L as desirable, though optimal is generally at the lower end. Lp(a) remains stable throughout adult life in most people, so a single measurement is often sufficient for long-term risk assessment.

High Lp(a) levels

High values usually reflect inherited elevation of this cholesterol-carrying particle, which behaves similarly to LDL but also promotes clotting and inflammation. Elevated Lp(a) independently increases risk for atherosclerotic cardiovascular disease, aortic stenosis, and thrombotic events. Levels above 50 mg/dL or 125 nmol/L are considered high risk. Unlike other lipids, Lp(a) does not respond meaningfully to diet or most standard lipid-lowering therapies.

Factors that influence Lp(a)

Lp(a) is minimally affected by lifestyle, fasting status, or most medications. It can rise modestly during acute inflammation, kidney disease, or menopause, and may fall slightly during estrogen therapy. Different assays report results in different units, so consistency in testing method aids interpretation over time.

Method: Laboratory-developed test (LDT) validated under CLIA; not cleared or approved by the FDA. Results are interpreted by clinicians in context and are not a stand-alone diagnosis.

Frequently Asked Questions about Lp(a) Testing

What is Lp(a) and how is it different from LDL cholesterol?

Lipoprotein(a), or Lp(a), is a cholesterol- and fat-carrying particle made in the liver. It has an LDL cholesterol “core” attached to a unique protein called apolipoprotein(a). Unlike standard LDL, Lp(a) is more likely to promote inflammation and blood clotting, which helps drive plaque buildup in artery walls. Because Lp(a) behaves differently than LDL, it can increase cardiovascular risk even when a standard lipid panel looks normal.

Why is Lp(a) testing important if my cholesterol levels are normal?

Lp(a) is an independent risk factor for heart attack, ischemic stroke, and aortic valve disease, even when LDL cholesterol and other lipid numbers are in range. Standard cholesterol tests often don’t capture this inherited risk. Testing Lp(a) can reveal a “hidden driver” of cardiovascular disease, explain early events in families without obvious risk factors, and help guide a more personalized prevention plan focused on lifelong vascular risk.

How do genetics affect Lp(a) levels, and can lifestyle change them?

Lp(a) levels are largely determined by your genes (the LPA gene) and typically stay relatively stable throughout life. Unlike many cholesterol markers, Lp(a) doesn’t respond much to diet, exercise, or other lifestyle changes, and it is not significantly lowered by most standard cholesterol medications. That’s why Lp(a) testing is useful: it identifies inherited cardiovascular risk that can’t be “fixed” by lifestyle alone.

What do Lp(a) results mean in mg/dL and nmol/L, and what ranges are considered low or high?

Many labs report Lp(a) as mg/dL or nmol/L. In this context, values below 30 mg/dL (or 75 nmol/L) are considered low and favorable. Levels above 50 mg/dL significantly raise risk for coronary artery disease, stroke, and calcific aortic stenosis. “Normal” ranges vary by lab, and optimal is generally considered the lowest measurable value because Lp(a) is a lifelong, genetically fixed risk factor.

How does high Lp(a) increase the risk of heart attack, stroke, and aortic valve disease?

High Lp(a) contributes to atherosclerosis by depositing oxidized lipids in artery walls and accelerating plaque buildup. Its structure also promotes inflammation and increases the tendency for clot formation (thrombosis), raising the risk of ischemic stroke and coronary events. Over decades, these effects can silently compound, and high Lp(a) is also linked to calcific aortic stenosis, a form of aortic valve disease.

Can high Lp(a) explain early heart attacks or strokes in families with no obvious risk factors?

Yes. Elevated Lp(a) is inherited and can drive cardiovascular disease even when traditional risk factors - like high LDL cholesterol - aren’t present. Because high Lp(a) has no symptoms and isn’t always detected on standard lipid panels, it can be a missing explanation for early heart attacks or strokes in families. Identifying high Lp(a) can clarify family history and help guide aggressive prevention strategies earlier in life.

How often should Lp(a) be measured, and do I need repeat testing?

Lp(a) is usually measured once in adulthood because levels are genetically determined and remain stable for most people. Repeat testing is generally not required. Interpretation can be affected by lab assay differences, so if serial monitoring is ever needed, using the same laboratory helps consistency. Lp(a) is minimally affected by fasting status or time of day, making testing convenient and reliable for establishing baseline lifetime cardiovascular risk.

Does fasting, time of day, illness, menopause, or pregnancy affect Lp(a) test results?

Lp(a) is minimally affected by fasting status, time of day, or acute illness, so timing is less critical than with some lipid tests. However, levels may rise modestly during menopause and fall slightly during pregnancy. Another key factor is that assay methods can vary between laboratories, which can affect reported values. If you ever compare results over time, using the same lab method improves accuracy and interpretation.

What prevention steps are recommended when Lp(a) is high even though it doesn’t respond to diet and exercise?

When Lp(a) is high, the goal is aggressive cardiovascular prevention since the inherited level is hard to change. This may include tighter control of other modifiable risks (like LDL cholesterol, blood pressure, and inflammation) and clinician-directed strategies such as statins or aspirin when appropriate. High Lp(a) can also identify people who may benefit from newer therapies designed specifically to lower Lp(a) as they enter clinical use.

Should my relatives get screened if I have elevated Lp(a), and who can inherit it?

Yes. Because Lp(a) is inherited and can be elevated from birth, finding a high level in one person can prompt family screening to protect relatives. Women, men, and children can all inherit high Lp(a), and it affects all ages and both sexes equally. Family screening is especially relevant when there’s a history of early heart disease or stroke, or when events occur despite normal standard cholesterol results.
