What is a lipid panel? A lipid panel (or lipid profile) is the standard blood test for cholesterol and other blood fats. It is one of the most common tests for assessing heart-disease risk. It reports four core numbers - total cholesterol, HDL, LDL, and triglycerides - and your doctor reads them together, alongside your age, blood pressure, and other risk factors.
What each number means
- Total cholesterol - the overall amount of cholesterol in your blood.
- HDL ("good") - helps carry cholesterol away from arteries; higher is generally better.
- LDL ("bad") - can contribute to plaque in arteries; usually the main treatment target.
- Triglycerides - a blood fat tied to diet, weight, alcohol, and metabolism.
Optimal and reference range
The figures below are typical lab reference ranges, which vary by lab and individual, and your personal targets depend on your overall heart risk. Discuss your results with your doctor or clinician.
| Marker | Often-cited desirable value | Units |
|---|---|---|
| Total cholesterol | below about 200 | mg/dL |
| HDL (good) | higher is generally better; often about 40 or more | mg/dL |
| LDL (bad) | lower is generally better; target set by clinician | mg/dL |
| Triglycerides | below about 150 | mg/dL |
Ranges vary by lab and individual; discuss your results with your doctor.
What helps
- A heart-healthy diet - more vegetables, fruit, whole grains, and fiber; less saturated and trans fat.
- Regular physical activity and a healthy weight.
- Limiting alcohol and not smoking - both affect blood fats.
- Taking any medication your doctor prescribes when lifestyle alone is not enough.
When to talk to your doctor
Go over your full lipid panel with your doctor, especially if any value is outside your lab's range or you have other heart-risk factors. Your clinician decides whether lifestyle changes are enough or whether medication is warranted, and how often to retest.

Do I need to fast before a lipid panel?
Some lipid panels ask for fasting, others do not. Follow the instructions your doctor or lab gives for your specific test.
Which number matters most?
It depends on your risk profile. LDL is often the main target, but HDL, triglycerides, and non-HDL all add context. Your doctor reads them together.
What if my numbers are slightly off?
Being a little outside a range is not automatically a problem. These are typical lab reference ranges, which vary by lab and individual - discuss the full picture with your clinician.
