For most adults, a desirable total cholesterol level is under 200 mg/dL, with LDL (“bad”) cholesterol below 100 mg/dL, HDL (“good”) cholesterol above 40 mg/dL for men or 50 mg/dL for women, and triglycerides below 150 mg/dL. These are the standard benchmarks you’ll see on a lipid panel, but the numbers that matter most for you depend on your age, sex, and overall heart disease risk.
Standard Adult Cholesterol Ranges
A routine lipid panel measures four things. Here’s how each one breaks down:
- Total cholesterol: Under 200 mg/dL is desirable. Between 200 and 239 is borderline high. At 240 or above, it’s considered high.
- LDL cholesterol: Under 100 mg/dL is optimal for most adults. Between 100 and 129 is near optimal, 130 to 159 is borderline high, 160 to 189 is high, and 190 or above is very high.
- HDL cholesterol: For men, anything below 40 mg/dL is considered low. For women, the threshold is higher: below 50 mg/dL is low. In both cases, higher is better, with levels between 40 and 80 (men) or 50 and 80 (women) being a healthy range.
- Triglycerides: Under 150 mg/dL is normal. Between 150 and 199 is borderline high, 200 to 499 is high, and 500 or above is very high.
The reason HDL thresholds differ by sex is that women generally produce more HDL, partly due to the influence of estrogen. So a number that looks acceptable for a man may actually signal increased risk for a woman.
Why LDL Targets Vary by Risk Level
The “under 100” LDL target applies to the general adult population, but your ideal number may be lower if you have elevated heart disease risk. Updated guidelines from the American Heart Association and American College of Cardiology, published in 2026, reintroduced specific LDL goals tied to a person’s risk profile:
- Borderline or intermediate risk: LDL below 100 mg/dL
- High risk (10% or greater chance of a heart event in the next 10 years): LDL below 70 mg/dL
- Very high risk (people who already have heart disease): LDL below 55 mg/dL
Your 10-year risk is calculated using factors like age, sex, race, total and HDL cholesterol, blood pressure, whether you take blood pressure medication, diabetes status, and smoking status. If you’ve had a heart attack, stroke, or stent placement, you fall into the very high risk category automatically, and the target drops significantly.
Non-HDL Cholesterol: A More Complete Picture
You may notice a value called non-HDL cholesterol on your results. This is simply your total cholesterol minus your HDL, and it captures all the cholesterol carried by particles that can contribute to artery buildup, not just LDL. For most adults, non-HDL should be below 130 mg/dL. That threshold drops for higher-risk individuals: below 100 mg/dL for those at high risk and below 85 mg/dL for those at very high risk.
Non-HDL cholesterol is increasingly considered a better predictor of cardiovascular disease than LDL alone. It picks up cholesterol from triglyceride-rich particles and other remnants that a standard LDL number misses. The Mayo Clinic notes that many healthcare professionals now prefer non-HDL over older measures like the total-to-HDL cholesterol ratio for gauging risk. If your LDL looks fine but your non-HDL is elevated, it can signal that other harmful particles are in play.
Normal Levels for Children and Teens
For anyone 19 or younger, the thresholds are lower across the board:
- Total cholesterol: Under 170 mg/dL
- LDL: Under 110 mg/dL
- Non-HDL: Under 120 mg/dL
- HDL: Above 45 mg/dL
Children don’t have separate cutoffs by sex the way adults do. Screening is typically recommended once between ages 9 and 11 and again between 17 and 21, though children with a family history of early heart disease or high cholesterol may be tested sooner.
Triglycerides and What High Levels Mean
Triglycerides are the most common type of fat in your blood, and they respond strongly to what you eat. After a meal, levels rise and typically peak three to four hours later. A level of 150 mg/dL or higher is a risk factor for metabolic syndrome, a cluster of conditions that also includes high blood pressure, high blood sugar, and excess abdominal fat. At 200 mg/dL and above, your risk for coronary artery disease increases. Levels at 500 or above carry an additional danger: they can trigger pancreatitis, a painful and potentially serious inflammation of the pancreas.
Do You Need to Fast Before the Test?
The traditional advice was to fast for 9 to 12 hours before a lipid panel, but this is changing. Medical societies across North America, Europe, and elsewhere now endorse nonfasting lipid panels as equally useful for most people. Eating before the test has a modest effect on results: triglycerides rise by an average of about 26 mg/dL after a meal, while total cholesterol and LDL each drop by roughly 8 mg/dL. HDL stays essentially the same whether you fast or not.
For routine screening, a nonfasting draw is fine. If your nonfasting triglycerides come back above 400 mg/dL, your doctor may ask you to repeat the test after fasting to get a more precise reading. Otherwise, the convenience of skipping the fast makes it more likely you’ll actually get tested, which matters more than a small shift in numbers.
How to Read Your Results in Context
A single number on your lab report doesn’t tell the whole story. Two people with the same LDL of 130 mg/dL can have very different risk profiles depending on their age, blood pressure, and whether they smoke or have diabetes. That’s why the newer guidelines emphasize looking at your full cardiovascular picture rather than treating cholesterol in isolation.
When reviewing your results, compare each value against the ranges above, but pay special attention to non-HDL cholesterol and your overall risk factors. A “normal” LDL of 95 mg/dL is perfectly fine for a healthy 35-year-old but may be too high for a 60-year-old with diabetes and high blood pressure, where the goal would be under 70 or even under 55. Your numbers are only meaningful in the context of your health as a whole.
