Lipoprotein-A (Lp-A)

Inherited Heart Risk Marker

Lipoprotein(a) is a genetically determined lipid particle that independently increases the risk of heart attack and stroke. Testing is recommended once in a lifetime since levels are largely inherited.

About This Test

What the Lipoprotein-A (Lp-A) test tells you

Lipoprotein(a) is an unusual cholesterol-carrying particle. At its core it resembles LDL, the particle most people know as harmful cholesterol, but it carries an extra protein wrapped around it called apolipoprotein(a). That extra protein happens to look very much like plasminogen, one of the body's clot-dissolving proteins, and it appears to interfere with that system. The result is a particle that both deposits cholesterol in the artery wall and makes clots a little harder to break down.

What sets this marker apart from the rest of a lipid panel is that its level is set almost entirely by the genes you inherit. It settles at its adult level in childhood and stays broadly stable for the rest of life, barely moved by diet, weight or exercise. That is why it is usually measured once rather than repeatedly. A raised level is an independent contributor to narrowing of the coronary and brain arteries and to stiffening of the aortic valve, adding risk over and above whatever LDL cholesterol is doing.

Knowing your level does not lead to treatment of the particle itself, because no widely available medicine specifically lowers it, though several are being studied. What it changes is the intensity with which everything else is managed: a doctor aware of a high level will usually push harder on LDL cholesterol, blood pressure, smoking, weight and blood sugar, because the background risk being added cannot be removed. It also carries information for the family, since parents, siblings and children may share the same inherited level and can be tested themselves.

Why Get Tested?

Recommended at least once for cardiovascular risk assessment, especially with a family history of premature heart disease or when cardiovascular events occur despite optimal LDL control.

  • A once-in-a-lifetime measurement

    Because the level is inherited and stays stable, a single test usually answers the question for good rather than needing yearly repetition.

  • Risk a lipid panel misses

    Standard cholesterol testing does not capture this particle, so someone with reassuring lipid results can still carry a meaningful extra risk.

  • Explaining early family heart disease

    When heart attacks or strokes have happened young in a family, an inherited high level is one of the explanations worth checking for.

  • Sharpening prevention decisions

    A raised level often prompts a doctor to treat other modifiable risk factors more firmly, since this one cannot be lowered directly.

When This Test Is Ordered

Reasons your doctor may request the Lipoprotein-A (Lp-A) test

Your doctor may order this test for any of the reasons below. Some are routine checks, others follow specific symptoms or an earlier result.

  • Family history

    • A parent, brother or sister developed heart disease or had a stroke at a young age.
    • A close relative is already known to have a high level of this particle.

  • Events despite good control & valve disease

    • You have had a cardiovascular event despite well-controlled cholesterol and blood pressure.
    • Narrowing of the aortic valve has been found, particularly at a younger age than expected.

  • Deciding treatment intensity

    • Your doctor is deciding how aggressively to treat borderline cholesterol or blood pressure.

Prep note
Physician reviewed

No fasting is needed and the test can be taken at any time of day, although it is often collected together with a lipid profile, in which case follow the fasting instruction given for that panel.

Take your usual medicines. Because the level is genetically set, there is no benefit in changing diet, exercise or alcohol intake beforehand.

Postpone the test if you have an acute illness or have recently had a heart attack or major surgery, since the level can shift temporarily during those periods. Tell the team about thyroid disease, kidney disease, pregnancy or hormone therapy, all of which can influence the result.

Understanding Your Results

An Optimal result, reported in mg/dL, means this particle is not adding to your cardiovascular risk, though that is not an assurance that your arteries are healthy. A Borderline value is weighed against your overall risk: family history, LDL cholesterol, blood pressure, smoking and blood sugar. A High result adds risk on top of whatever LDL cholesterol is doing, contributing to narrowing of the arteries and stiffening of the aortic valve. The level is set almost entirely by the genes you inherit, settles in childhood and barely moves with diet, weight or exercise, so one measurement is normally enough and a raised result is a reason to manage every other risk factor more firmly. An untreated underactive thyroid, kidney disease with heavy protein loss, the menopause or a recent acute illness can shift it. Your doctor interprets it alongside your symptoms and family history.

Ranges are a guide: your physician interprets your result alongside your symptoms and history.

Reading a High or Low Result

  • What a higher result can point to

    • Inherited variation in the gene that codes for the particle's extra protein, which is by far the dominant reason.
    • Family and ancestral background, since typical levels differ between populations.
    • Kidney disease with heavy protein loss in the urine, and some forms of chronic kidney impairment.
    • An untreated underactive thyroid, which is associated with higher levels that fall once the thyroid is corrected.
    • The menopause and the fall in oestrogen that accompanies it, which nudges levels modestly upward.

These are possibilities, not diagnoses. A single value outside the reference range is interpreted alongside your symptoms, history and other tests: your doctor decides what it means for you.

Limitations & Safety

What this test cannot tell you

  • A high level cannot be lowered directly by any widely approved medicine at present, so the result guides overall risk management rather than a specific treatment.
  • Different laboratory methods report the particle in different ways, so results from separate laboratories are not always directly comparable.
  • A level that is not raised removes one risk factor but says nothing about the rest, and does not mean the arteries are healthy.

Risks of the blood draw

  • Mild bruising or brief soreness where the needle went in.
  • Occasional lightheadedness, which settles after a few minutes of rest.
  • Bleeding or infection at the site, which is rare with sterile single-use equipment.
Key Points
  • 1The level is largely inherited, settles in childhood and stays stable, so one measurement is normally enough.
  • 2It adds cardiovascular risk on top of LDL cholesterol rather than duplicating it.
  • 3Diet, exercise and weight loss have very little effect on it, which is not a sign that those efforts are wasted.
  • 4A raised result is a reason to manage every other risk factor more firmly, not a reason to assume an event is coming.
  • 5Because it runs in families, a high result is worth discussing with close relatives.

A standard lipid panel measures cholesterol carried in broad categories of particle and does not identify this one separately. Because its level is genetically fixed rather than something that changes with lifestyle, it is treated as a separate, usually one-off assessment.
