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 (bad cholesterol), it behaves differently in the body and is associated with a higher risk of clotting and cardiovascular events.
Why Is This Test Done?
Your doctor may order this test if you have a family history of early heart disease, certain genetic conditions, or if you’ve had a stroke or heart attack. It can also be part of routine cardiovascular risk assessment.
How Is the Test Performed?
A blood sample is drawn from a vein, usually in your arm. The test measures the concentration of lipoprotein(a) using a specialized immunoassay method to detect its presence in serum or plasma.
What Do Results Mean?
Higher levels of lipoprotein(a) may increase your risk of heart disease or stroke. While there’s no single reference range, elevated levels often warrant further evaluation or lifestyle/medication adjustments to manage risk.
