Lipoprotein(a) Blood Test
The Lp(a) Test measures lipoprotein(a), a genetic form of cholesterol-carrying particle. Higher levels can add to cardiovascular risk, and the test helps refine risk assessment when standard lipids are not enough.

Quick answer
The Lp(a) Test measures lipoprotein(a), a particle that carries cholesterol in the blood. The level is largely determined by genetics and stays fairly stable over a person's life. Higher values are associated with an increased risk of cardiovascular disease, including heart attack and stroke. The test is often used when a clinician wants extra information beyond a standard lipid panel, especially with a family history of early heart disease.
What this test measures
Lipoprotein(a) is a type of LDL-like particle with an additional protein attached. The amount in the blood is mostly inherited and differs widely between people. It remains relatively stable, so it usually does not need repeated testing in most situations.
The test requires a blood sample, and fasting is often not necessary. Because levels are genetically set, a single measurement is usually enough. Results are interpreted alongside standard cholesterol values and the person's overall risk profile and family health history.
Testing may be considered when someone has early cardiovascular disease, a strong family history, or risk factors that are not fully explained by standard lipids. A qualified healthcare provider should interpret the result and discuss what it means for prevention and monitoring.
- Lipoprotein(a) level
- Total cholesterol when ordered together
- LDL cholesterol when ordered together
- HDL cholesterol when ordered together
- Triglycerides when ordered together
- Apolipoprotein B when included
- Inflammatory markers when included
Why people order this test
- Refine cardiovascular risk assessment beyond standard lipids
- Evaluate risk when early heart disease runs in the family
- Add information for people with unexplained cardiovascular events
- Provide a stable inherited marker that usually needs one measurement
- Help a clinician decide whether prevention should be intensified
- Interpret alongside cholesterol and other risk factors
How to prepare
No fasting is usually required for an Lp(a) test, but follow the instructions provided with the test order. If a standard lipid panel is drawn at the same time, fasting may be requested for that portion.
Understanding your results
Results are usually available within one to three business days. Lp(a) is interpreted with standard cholesterol values, family history, and other risk factors. A qualified healthcare provider should explain what the level means.

Frequently Asked Questions
What is lipoprotein(a)?
It is an LDL-like particle with an extra protein attached. Levels are mostly inherited and can contribute to cardiovascular risk.
Why is Lp(a) tested?
It adds risk information beyond a standard lipid panel, especially when there is a family history of early heart disease.
Is Lp(a) inherited?
Yes. The level is largely determined by genetics, which is why it can run in families and stay stable over time.
Does Lp(a) change over time?
It is relatively stable compared with other lipids, so repeat testing is often unnecessary. A clinician can advise if retesting is needed.
Do I need to fast for an Lp(a) test?
Fasting is usually not required, unless other tests drawn at the same time call for it. Follow the instructions provided with your test order.
Can treatment lower Lp(a)?
Some approaches may have a limited effect on Lp(a). A qualified healthcare provider can discuss whether any option is appropriate.
