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 LDL (low-density lipoprotein), or 'bad' cholesterol, it behaves differently in the body. Elevated levels may contribute to artery plaque buildup, increasing the risk of heart attacks or strokes.

Why Might You Need This Test?

Your healthcare provider may order this test if you have a family history of early heart disease, certain genetic conditions, or if you’re at higher risk for cardiovascular issues. It’s also sometimes checked in people with known heart disease to monitor progression or guide treatment decisions.

How Is the Test Performed?

A small blood sample is drawn from a vein, usually in your arm. The sample is sent to a lab where it’s analyzed to measure lipoprotein(a) levels. Results are typically available within 1–3 business days.

What Do the Results Mean?

There’s no single 'normal' range for lipoprotein(a) because levels vary widely among individuals. Your results will be compared to your personal baseline and clinical context (e.g., age, family history, other health conditions) to determine significance. High levels may prompt further evaluation or lifestyle/medication adjustments.
