What Is Lipoprotein(a)?

Lipoprotein(a) is a unique lipoprotein particle that combines cholesterol with a protein called apolipoprotein(a). Unlike other cholesterol particles, lipoprotein(a) has a strong genetic component and may contribute to plaque buildup in arteries over time.

Why Is This Test Done?

Your healthcare provider may order this test if you have a family history of heart disease, stroke, or early-onset coronary artery disease, or if you have other risk factors like high blood pressure or diabetes.

How Is the Test Performed?

A blood sample is drawn from a vein, usually in your arm. The sample is sent to a lab where it is analyzed using an immunoassay method to measure lipoprotein(a) levels.

What Do Results Mean?

Higher levels of lipoprotein(a) may increase your risk of cardiovascular events, but individual results depend on other health factors. Your provider will interpret results in the context of your overall health.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions

Why might my doctor ask for this test?
Your doctor may recommend this test to evaluate your risk for heart disease, especially if you have a family history of cardiovascular issues or other risk factors like high cholesterol or hypertension.
How often should I get this test?
There’s no standard frequency for this test, as it depends on your risk profile. Your healthcare provider will determine if and when to repeat it based on your medical history and current health status.
Can lifestyle changes affect lipoprotein(a) levels?
While lifestyle factors like diet and exercise can influence overall cholesterol levels, lipoprotein(a) levels are largely determined by genetics. However, managing other cardiovascular risk factors (like blood pressure and diabetes) can still benefit heart health.
