Understanding Lipoprotein A What It Is and Who Should Be TestedLipoprotein A, often abbreviated as Lp(a), is a type of lipoprotein found in the blood. It plays a significant role in cardiovascular health, yet many people are unaware of its existence and potential impact. This blog post aims to shed light on what Lipoprotein A is, why it matters, and who should consider getting tested.

What is Lipoprotein A?

Lipoprotein A is a particle made up of an LDL (low-density lipoprotein) cholesterol core and a protein called apolipoprotein(a). LDL cholesterol is commonly known as “bad cholesterol” because high levels can lead to plaque buildup in arteries and result in cardiovascular diseases. Lp(a) is similar to LDL but is distinct due to the presence of apolipoprotein(a).

Why is Lipoprotein A Important?

Elevated levels of Lp(a) are associated with an increased risk of cardiovascular diseases, including heart attacks, strokes, and aortic valve stenosis. Unlike other cholesterol measures, Lp(a) levels are primarily determined by genetics and are less influenced by lifestyle factors such as diet and exercise. This makes it a critical factor in assessing cardiovascular risk, particularly in individuals who might not otherwise be identified as high-risk through standard cholesterol testing.

Who Should Be Tested for Lipoprotein A?

Given the genetic nature of Lp(a), testing is particularly important for individuals with certain risk factors. The following groups should consider getting tested:

  1. Family History of Cardiovascular Disease: If you have close relatives who have experienced heart attacks, strokes, or other cardiovascular events, especially at a young age, testing for Lp(a) is advisable.
  2. Personal History of Cardiovascular Events: Individuals who have had heart attacks, strokes, or other cardiovascular events should be tested to better understand their risk factors.
  3. High Cholesterol Despite Treatment: If you have high cholesterol that does not respond well to traditional treatments such as statins, Lp(a) testing might provide additional insights.
  4. Diagnosed with Certain Conditions: People diagnosed with conditions such as familial hypercholesterolemia or other lipid disorders should consider Lp(a) testing.
  5. Ethnic and Genetic Predispositions: Certain ethnic groups, such as those of South Asian, African, and European descent, may have higher average levels of Lp(a).

Comprehensive Q&A Section

Q1: How is Lipoprotein A measured?

A1: Lipoprotein A is measured through a blood test. The test is similar to other cholesterol tests and involves drawing a blood sample, which is then analyzed in a laboratory to determine the Lp(a) level.

Q2: What is considered a high level of Lipoprotein A?

A2: Lp(a) levels are measured in milligrams per deciliter (mg/dL). A level above 30 mg/dL is generally considered elevated, but specific thresholds can vary. It’s best to consult with your healthcare provider for interpretation based on your overall health and risk factors.

Q3: Can lifestyle changes lower Lipoprotein A levels?

A3: Unlike other cholesterol types, Lp(a) levels are not significantly affected by lifestyle changes such as diet and exercise. They are largely determined by genetics. However, maintaining a healthy lifestyle is still crucial for managing overall cardiovascular risk.

Q4: Are there treatments available to lower Lipoprotein A levels?

A4: Currently, there are no medications specifically approved to lower Lp(a) levels. However, ongoing research and clinical trials are exploring potential treatments. In the meantime, managing other cardiovascular risk factors, such as high blood pressure and LDL cholesterol, is essential.

Q5: How often should Lipoprotein A be tested?

A5: Lp(a) levels are relatively stable over a person’s lifetime, so repeated testing is typically not necessary unless there are significant changes in health status or new cardiovascular events. Your healthcare provider can offer guidance on the need for follow-up testing.

Q6: Can children be tested for Lipoprotein A?

A6: Yes, children can be tested for Lp(a), especially if there is a strong family history of cardiovascular diseases. Early detection can help in managing risk factors from a young age.

Q7: How can I get tested for Lipoprotein A?

A7: If you believe you are at risk or have the conditions mentioned, discuss with your healthcare provider. They can order the Lp(a) test as part of a routine blood panel or a more comprehensive lipid profile.


Understanding and testing for Lipoprotein A is a crucial step in assessing and managing cardiovascular risk. While Lp(a) is primarily influenced by genetics and less so by lifestyle, knowing your levels can help you and your healthcare provider take appropriate measures to protect your heart health. If you fall into one of the high-risk categories, consider discussing Lp(a) testing with your healthcare provider.
