A normal lipid panel shows total cholesterol under 200 mg/dL, LDL under 100 mg/dL, HDL at 60 mg/dL or above, and triglycerides below 150 mg/dL. These are the targets for adults age 20 and older, though the numbers shift slightly for children and differ between men and women when it comes to HDL.
What a Lipid Panel Measures
A standard lipid panel reports four or five values from a single blood draw. Each one captures a different piece of your cholesterol and fat picture.
- Total cholesterol: The combined amount of all cholesterol in your blood, including both protective and harmful types.
- LDL (low-density lipoprotein): Often called “bad” cholesterol because it deposits fat inside artery walls, narrowing them over time.
- HDL (high-density lipoprotein): The “good” cholesterol. It works like a cleanup crew, carrying excess cholesterol back to the liver for removal.
- Triglycerides: The most common type of fat in your blood. Your body converts extra calories, sugar, and alcohol into triglycerides and stores them in fat cells.
- Non-HDL cholesterol: Your total cholesterol minus your HDL. This single number captures all the cholesterol types that can damage arteries, making it a useful summary figure. A healthy non-HDL level is under 130 mg/dL for adults.
Some labs also estimate VLDL (very-low-density lipoprotein), which mainly carries triglycerides through the bloodstream. There’s no direct test for it. Instead, the lab divides your triglyceride number by five. A normal VLDL is under 30 mg/dL.
Normal Ranges for Adults
For men and women age 20 and older, the healthy targets are mostly the same, with one exception: the floor for HDL is lower in men.
- Total cholesterol: Less than 200 mg/dL
- LDL: Less than 100 mg/dL
- HDL: 60 mg/dL or higher is ideal. For men, anything below 40 mg/dL is considered low. For women, the low threshold is 50 mg/dL.
- Non-HDL: Less than 130 mg/dL
- Triglycerides: Less than 150 mg/dL
These numbers represent optimal levels. A total cholesterol of 210 mg/dL or an LDL of 115 mg/dL doesn’t mean you’re in immediate danger, but it does signal that your risk is trending upward. The further above the cutoffs you go, the more seriously you and your provider should discuss next steps.
Normal Ranges for Children and Teens
For anyone age 19 or younger, the targets are tighter than adult ranges because lipid levels naturally rise with age. Healthy levels for children and adolescents are:
- Total cholesterol: Less than 170 mg/dL
- LDL: Less than 110 mg/dL
- HDL: More than 45 mg/dL
- Non-HDL: Less than 120 mg/dL
There is no universal consensus on when every child should be screened. The U.S. Preventive Services Task Force currently says the evidence is insufficient to recommend routine lipid screening for everyone under 20. Children with a family history of early heart disease or very high cholesterol are typically tested earlier.
How Triglyceride Levels Are Classified
Triglycerides get their own severity scale because the risks escalate sharply at higher levels. Below 150 mg/dL is normal. Above that, the Cleveland Clinic breaks it down as follows:
- Mild: 150 to 199 mg/dL
- Moderate: 200 to 499 mg/dL
- Severe: 500 mg/dL or higher
Mildly elevated triglycerides are common and often respond to changes in diet, exercise, and alcohol intake. Once levels climb above 500 mg/dL, the concern shifts beyond heart disease: severely high triglycerides increase the risk of pancreatitis, a painful and potentially life-threatening inflammation of the pancreas. At any elevated level, high triglycerides also contribute to coronary artery disease, stroke, and peripheral artery disease.
Why HDL Matters as Much as LDL
Most people focus on getting LDL down, but HDL that’s too low is an independent risk factor for heart disease. HDL particles pull cholesterol out of artery walls and transport it to the liver, so having more of them provides a protective effect. That’s why the goal isn’t just “not low” but ideally 60 mg/dL or above.
Your non-HDL number puts this in context. Because it equals total cholesterol minus HDL, it captures everything working against your arteries in a single figure. An optimal non-HDL is under 130 mg/dL for most people. If you’ve already had a heart attack or have established cardiovascular disease, the target is typically even lower.
Do You Need to Fast Before the Test?
For years, a 9- to 12-hour fast was standard before any lipid panel. Updated guidance from the Association for Diagnostics and Laboratory Medicine has relaxed that rule. Most adults can now have their blood drawn without fasting, and the results are considered reliable for total cholesterol, LDL, and HDL.
Fasting is still recommended in two situations: if you have known high triglycerides (since a recent meal can temporarily spike triglyceride levels by hundreds of points) or if you’re a child with elevated non-HDL cholesterol on a previous test. If your provider hasn’t specifically asked you to fast, a non-fasting draw is generally fine.
Reading Your Results in Context
A lipid panel is a snapshot, not a verdict. A single borderline result can reflect what you ate the week before, a recent illness, or normal biological variation. When a number comes back outside the healthy range, providers often retest after a few weeks before drawing conclusions.
Your numbers also don’t exist in isolation. Someone with an LDL of 110 mg/dL, no family history of heart disease, normal blood pressure, and no diabetes is in a very different position from someone with the same LDL who smokes and has high blood pressure. That’s why lipid panels are interpreted alongside your full risk profile, not as standalone pass-or-fail scores. The numbers give you a starting point for understanding where you stand and what, if anything, needs to change.
