Lipoprotein(a) [Lp(a)] concentration

What Is Lipoprotein(a)?

Lipoprotein(a) is a unique lipoprotein particle that combines cholesterol with a protein called apolipoprotein(a). While it shares some traits with regular cholesterol, it behaves differently in the body and may contribute to plaque buildup in arteries more than other fats. This test helps assess your risk for conditions like heart attack or stroke, especially if you have a history of high cholesterol or family history of cardiovascular disease.

Why Might You Need This Test?

Your doctor may order this test if you have a higher risk of heart disease, such as if you have: - A family history of heart disease or stroke - High cholesterol or other risk factors for cardiovascular issues - Conditions like diabetes or high blood pressure It may also be used to monitor treatment progress if you’re already at higher risk.

How Is the Test Performed?

A small blood sample is taken from a vein in your arm. The sample is sent to a lab where it is analyzed to measure the exact amount of lipoprotein(a) in your blood.

What Do the Results Mean?

Results show your lipoprotein(a) level in milligrams per deciliter (mg/dL). Higher levels may indicate an increased risk of heart disease, but this depends on other health factors. Your doctor will discuss the results in the context of your overall health and medical history.
