What Is Lipoprotein(a)?

Lipoprotein(a) is a unique lipoprotein particle that combines cholesterol with a protein called apolipoprotein(a). Unlike other cholesterol types, it’s not fully broken down by the body, which may contribute to plaque buildup in arteries over time.

Why Might You Need This Test?

Doctors may order this test if you have a family history of heart disease, stroke, or high cholesterol, or if you’re at higher risk for vascular complications. It’s also used in some genetic testing or monitoring for conditions like aortic aneurysms.

How Is the Test Done?

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

What Does the Result Mean?

Results are reported in milligrams per deciliter (mg/dL) or other units, but exact values depend on the lab. Higher levels may signal increased risk for cardiovascular events, though results alone don’t diagnose disease.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions

Why was I asked to have this test?
Your doctor may have recommended it to evaluate your risk for heart disease, especially if you have a family history of cardiovascular issues or other risk factors like high blood pressure or diabetes.
What does a high or low result mean?
Higher levels of lipoprotein(a) are associated with an increased risk of artery-related problems, such as heart attacks or strokes. However, results should be interpreted in the context of your overall health and other risk factors. Low levels don’t necessarily mean you’re at low risk.
Can I lower my lipoprotein(a) level?
While lifestyle changes like diet and exercise can help manage other cholesterol levels, there’s no specific medication to lower lipoprotein(a) levels. Some medications may be explored based on your doctor’s assessment of your risk profile.
