What is this test?

A lipid panel measures the amounts of cholesterol and triglycerides in your blood. It may include total cholesterol and cholesterol carried by LDL and VLDL, with some results calculated from other measurements.

Why might I need this test?

Clinicians use this test to help assess cardiovascular risk, evaluate conditions that can affect blood fats, and monitor cholesterol-lowering treatment or changes in diet and lifestyle.

How is the test performed?

A blood sample is collected and analyzed in a laboratory. The laboratory may measure the lipid components directly or calculate certain cholesterol values using the other results.

How do I prepare for the test?

Fasting may be requested, commonly for 8 to 12 hours, while water is usually allowed. Follow your clinician's instructions and tell the laboratory if you recently ate, exercised intensely, or consumed alcohol.

Frequently asked questions

Do I need to fast before this test?
It depends on your clinician's instructions and the laboratory's testing method. If fasting is requested, it is commonly 8 to 12 hours with water allowed.
What does a high LDL cholesterol result mean?
High LDL cholesterol can contribute to fatty buildup in artery walls and increase the risk of heart disease and stroke. A single result should be discussed with your clinician, who may recommend repeat testing or treatment.
Can medications or supplements affect the results?
Yes. Cholesterol medicines, some other medicines, supplements, and recent dietary or exercise changes can affect lipid levels. Do not stop prescribed treatment without medical advice.
