This page explains the lp(a) test, what it measures, and how to arrange it. The Lp(a) test measures the amount of lipoprotein(a), a type of cholesterol-carrying particle in your blood. It is usually ordered when a person has a personal or family history of early heart disease, or when standard cholesterol tests do not fully explain their risk. Across Louisiana, part of South, the lp(a) test can be ordered directly and collected at a certified site — no referral required.

The Lp(a) test measures the amount of lipoprotein(a), a type of cholesterol-carrying particle in your blood. It is usually ordered when a person has a personal or family history of early heart disease, or when standard cholesterol tests do not fully explain their risk.

What it measures

  • Lipoprotein(a) mass or particle number — The main result, reported in mg/dL or nmol/L, showing how much Lp(a) is in your blood.
  • LDL cholesterol (sometimes) — Often checked at the same time to see your overall cholesterol picture.
  • Total cholesterol — A sum of all cholesterol types in your blood.
  • HDL cholesterol — The 'good' cholesterol that helps remove excess cholesterol.
  • Triglycerides — Another type of blood fat that can affect heart risk.

Who it is for

A clinician may order this test if you have a family history of early heart attacks or strokes, or if your standard cholesterol results seem unusual for your risk level.

Preparation

No fasting is usually required for the Lp(a) test alone. However, if other cholesterol tests are done at the same time, you may be asked to fast for 9 to 12 hours.

Results and what they mean

Results are reported as a number, often in mg/dL or nmol/L, and may be flagged as normal, borderline, or high based on lab-specific ranges. A clinician interprets your Lp(a) level along with your other risk factors. This is general information, not medical advice; discuss your results with a healthcare professional.

Frequently asked questions

Is this test covered by insurance?

Coverage varies by plan. Some insurers cover it when there is a family history of early heart disease; check with your provider.

Can I eat before the test?

Yes, unless your clinician also orders other cholesterol tests that require fasting. Follow the instructions you are given.

How often should I get an Lp(a) test?

Lp(a) levels are mostly genetic and stable over life, so most people only need it once. Your clinician will decide if repeat testing is needed.

What if my result is high?

A high level can mean higher heart risk, but it is not a diagnosis. Your clinician will consider your full health picture and discuss next steps.
