Cholesterol results, explained

What do LDL, HDL, and triglycerides mean on a lipid panel?

A lipid panel can be hard to read when the abbreviations are unfamiliar. Start by identifying what each result measures, then ask how the full panel fits your health history and what your care team recommends next.

Read the parts of a lipid panel

A lipid panel reports total cholesterol, LDL cholesterol, HDL cholesterol, and triglycerides. Total cholesterol is the overall cholesterol measure. LDL and HDL are lipoproteins, which carry cholesterol through the blood. Triglycerides are another type of blood fat, not a type of cholesterol.

LDL stands for low-density lipoprotein. High LDL levels can contribute to plaque buildup in artery walls and raise the risk of heart disease and stroke. People sometimes call LDL “bad cholesterol,” but that label does not explain what your result means on its own.

HDL, or high-density lipoprotein, carries cholesterol back to the liver, which removes it from the body. It is often called “good cholesterol.” Consider the HDL result alongside the rest of the panel. A higher HDL result does not, by itself, cancel the concern associated with high LDL.

Triglycerides are a type of fat in the blood that your body uses for energy. High triglycerides together with low HDL or high LDL can raise the risk of health problems. They belong in the discussion even though they measure something different from cholesterol.

If you have seen only a summary or a flagged result, ask for the full panel. With all the results in front of you, you can ask which ones your care team wants to discuss.

Ask what the results mean for you

A clinician considers cholesterol test results alongside your medical and family history, a physical exam, and other risk factors. Eating habits, physical activity, and medicines may also come up in the discussion. Ask how your own history affects the interpretation and what goal, if any, applies to you.

You might ask:

  • Which result or combination of results needs attention?
  • What cholesterol level are we aiming for in my situation?
  • How do my medical history, family history, or other risk factors affect that goal?
  • Is there a term or result in the report you can explain?

A number on a report does not by itself establish that you have an artery blockage or show what treatment you need. Ask your care team to explain the concern behind any recommended next step. If you have earlier results, bring them or note their dates so you can ask whether the change affects the plan. If you do not know your family history, say so rather than guessing.

Leave with a plan you understand

If you have high LDL cholesterol and triglyceride levels, your care team may recommend lifestyle changes, medicine, or both. Choosing foods with less saturated fat and quitting smoking are examples of lifestyle changes that may be discussed. Ask which changes fit your situation and what support is available. If medicine is recommended, ask what it is intended to address and how to take it.

Before another lipid panel, ask whether you need to fast and follow the directions given for that test. Ask when your next panel should be done and what you should know before arranging it.

Before you finish the visit or call, write down the agreed next step, any question that still needs an answer, and whom to contact about the plan. You can use that note when you follow up.
