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 similarities with LDL (low-density lipoprotein), it behaves differently in the body and is associated with a higher risk of clotting and heart disease. Elevated levels may be detected even if your overall cholesterol is normal.

Why Might You Need This Test?

Your doctor may order this test if you have a family history of heart disease, stroke, or early-onset cardiovascular issues, or if you have other risk factors like high blood pressure or diabetes. It’s also sometimes checked in people with certain genetic conditions or those undergoing preventive screening.

How Is the Test Performed?

A small blood sample is drawn from your arm, typically in a clinic or lab. The sample is processed and analyzed to measure the concentration of lipoprotein(a) in your blood.

What Do Results Mean?

Results are reported as a numerical value representing the concentration of lipoprotein(a) in milligrams per deciliter (mg/dL). While there are no universally accepted reference ranges for everyone, higher levels may indicate increased cardiovascular risk, prompting further evaluation or lifestyle changes.
