What is this test?

Lipoprotein(a), or Lp(a), is a cholesterol-carrying particle made partly from a protein called apolipoprotein(a). This qualitative serum or plasma test checks for the presence of Lp(a)-associated cholesterol rather than measuring its exact amount.

Why might I need this test?

A clinician may order this test when assessing cardiovascular risk or investigating a family history of high cholesterol or early heart disease. It may also be used as part of a broader evaluation of lipid-related health.

How is the test performed?

A blood sample is collected, usually from a vein, and the serum or plasma is analyzed by the laboratory. Because this is a qualitative test, the result is reported as present or absent, or with a similar positive or negative interpretation.

How do I prepare for the test?

Fasting is usually not required, but you should follow any instructions from your clinician or testing laboratory. Tell the healthcare team about medicines, supplements, or health conditions that could affect your cholesterol results.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions

Does a present result mean I have heart disease?
No. The result indicates the presence of Lp(a)-associated cholesterol, not the presence of heart disease. Cardiovascular risk depends on this finding together with your other cholesterol levels, medical history, and other risk factors.
Is this the same as an LDL cholesterol test?
No. LDL cholesterol and Lp(a) are different cholesterol-related particles. Your clinician may order both to understand your cardiovascular risk more completely.
Do I need to fast before this test?
Fasting is usually unnecessary unless your clinician specifically requests it. Follow the preparation instructions provided with your test order.
