What Is Lipoprotein(a)?

Lipoprotein(a) is a unique lipoprotein particle that combines cholesterol with a protein called apolipoprotein(a). While it shares similarities with LDL (low-density lipoprotein), it behaves differently in the body and is associated with higher risks of atherosclerosis and arterial blockages.

Why Might You Need This Test?

Your doctor may order this test if you have a family history of heart disease, stroke, or blood clots, or if you have conditions like high cholesterol, hypertension, or diabetes. It may also be used to monitor risk in people with known cardiovascular concerns.

How Is the Test Performed?

A blood sample is drawn from a vein, typically in your arm. The sample is sent to a lab for analysis using an immunoassay method to measure lipoprotein(a) concentration.

What Do Results Mean?

Results are reported in milligrams per deciliter (mg/dL). Higher levels may indicate an increased risk of cardiovascular events, though individual risk depends on other factors like lifestyle and overall health.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions

Why was this test ordered?
Your doctor may have recommended this test to assess your risk for heart disease or blood clots, especially if you have a family history of these conditions or other risk factors.
What does a high or low result mean?
High lipoprotein(a) levels may suggest a greater risk of cardiovascular problems, but they don’t replace other risk assessments. Your doctor will consider your overall health and other test results to guide treatment.
Can lifestyle changes affect this test?
Yes, managing cholesterol, blood pressure, and quitting smoking can help lower lipoprotein(a) levels and reduce cardiovascular risk. Some medications may also be prescribed to target this specific risk factor.
