Lipoprotein(a) mass concentration in serum/plasma

What Is Lipoprotein(a)?

Lipoprotein(a) is a unique lipoprotein particle that combines cholesterol with a protein called apolipoprotein(a). While it shares some similarities with LDL (low-density lipoprotein), it behaves differently in the body and is linked to higher risks of blood clots and heart disease. Elevated levels may indicate a genetic predisposition to cardiovascular issues.

Why Might You Need This Test?

Your healthcare provider may order this test if you have a family history of heart disease, stroke, or blood clots, or if you have other risk factors like high blood pressure or diabetes. It may also be used to monitor patients with known cardiovascular conditions.

How Is the Test Performed?

A blood sample is drawn from a vein, typically in your arm. The blood is then processed to separate the serum or plasma, where the lipoprotein(a) concentration is measured using a specialized laboratory technique.

What Do Results Mean?

Results are expressed in mass concentration units (e.g., grams per liter). While there are no universally accepted reference ranges, higher levels are generally associated with increased cardiovascular risk. Your provider will interpret results in the context of your overall health and medical history.
