A healthy total cholesterol level for adults is below 200 mg/dL, with LDL (“bad”) cholesterol under 100 mg/dL, HDL (“good”) cholesterol above 40 mg/dL for men or above 50 mg/dL for women, and triglycerides under 150 mg/dL. But these headline numbers only tell part of the story. Your overall cardiovascular risk depends on how these values relate to each other and to your personal health profile.
The Full Lipid Panel, Number by Number
When you get a cholesterol test, the results come back as a lipid panel with four or five values. Here’s what each one means and where you want it to land:
- Total cholesterol: Below 200 mg/dL is desirable. Between 200 and 239 is borderline high. At 240 or above, it’s considered high.
- LDL cholesterol: Below 100 mg/dL is optimal. Between 100 and 129 is near-optimal. From 130 to 159 is borderline high, 160 to 189 is high, and 190 or above is very high.
- HDL cholesterol: Below 40 mg/dL for men or below 50 mg/dL for women is considered low and increases heart disease risk. An HDL of 60 mg/dL or higher is protective.
- Triglycerides: Below 150 mg/dL is normal. Between 150 and 199 is borderline high. From 200 to 499 is high, and 500 or above is very high.
- Non-HDL cholesterol: This is your total cholesterol minus your HDL. It captures all the harmful types of cholesterol in one number. For most adults, the optimal level is below 130 mg/dL.
Many cardiologists now consider non-HDL cholesterol a better predictor of heart disease risk than either total cholesterol or LDL alone. It’s simple to calculate from your existing panel and gives a more complete picture of the cholesterol particles that damage arteries.
Why HDL Targets Differ for Men and Women
Women naturally tend to have higher HDL levels than men, largely due to estrogen’s effect on cholesterol metabolism. That’s why the low-HDL threshold is set 10 points higher for women (below 50 mg/dL) compared to men (below 40 mg/dL). If you’re a woman with an HDL of 45 mg/dL, that number might look adequate at first glance, but it actually falls into the increased-risk category. After menopause, HDL levels often drop and LDL levels rise, which is one reason cardiovascular risk climbs for women in their 50s and 60s.
Healthy Ranges for Children and Teens
Children and adolescents have different targets than adults. For anyone 19 or younger, healthy levels are:
- Total cholesterol: Below 170 mg/dL
- LDL: Below 110 mg/dL
- HDL: Above 45 mg/dL
- Non-HDL: Below 120 mg/dL
The CDC recommends that children get their cholesterol checked at least once between ages 9 and 11, then again between ages 17 and 21. Kids with obesity, diabetes, or a family history of high cholesterol may need more frequent screening.
What Your Risk Category Actually Means
The latest guidelines from the American Heart Association and American College of Cardiology don’t just look at your cholesterol numbers in isolation. Doctors now use a risk calculator that factors in your age, blood pressure, cholesterol, diabetes status, and other variables to estimate your 10-year risk of a cardiovascular event like a heart attack or stroke. For adults aged 30 to 79, that risk falls into four categories: low (under 3%), borderline (3% to just under 5%), intermediate (5% to just under 10%), or high (10% or above).
This matters because two people with the same LDL number can have very different treatment plans. Someone at low risk with an LDL of 140 mg/dL might focus entirely on diet and exercise. Someone at high risk with the same LDL may benefit from medication, with a target of getting LDL below 70 mg/dL and non-HDL below 100 mg/dL. The numbers on your lab report are a starting point, not the whole picture.
Do You Need to Fast Before a Cholesterol Test?
For most people, no. The American College of Cardiology’s consensus position is that nonfasting lipid profiles are appropriate for the majority of patients, including initial screenings, routine risk assessments, children, older adults, and people with diabetes who risk low blood sugar from skipping meals. Large observational studies found that the maximum difference between fasting and nonfasting results is clinically small: about 26 mg/dL for triglycerides and roughly 8 mg/dL for total cholesterol, LDL, and non-HDL. HDL doesn’t change at all.
Fasting tests (typically 9 to 12 hours without food) are still needed in certain situations: when triglycerides come back above 400 mg/dL, when you’re being evaluated for a specific lipid disorder, or when recovering from pancreatitis caused by very high triglycerides. If your doctor doesn’t specify fasting, a nonfasting draw is perfectly reliable.
How Often to Get Tested
Most healthy adults should have their cholesterol checked every 4 to 6 years. If you have heart disease, diabetes, or a family history of high cholesterol, you’ll need testing more frequently, often annually or as your doctor recommends based on your treatment plan. People who’ve recently started a cholesterol-lowering medication typically get rechecked within a few months to see how well it’s working.
Non-HDL and ApoB: The Numbers That May Matter Most
If you’ve seen mentions of apolipoprotein B (ApoB) testing, it’s a marker that counts the actual number of harmful cholesterol particles in your blood rather than just the amount of cholesterol they carry. Levels above 130 mg/dL indicate higher risk for heart and blood vessel disease. For people on medication, some cardiology guidelines recommend a target below 65 to 80 mg/dL. Normal ranges run from 66 to 133 mg/dL for men and 60 to 117 mg/dL for women.
ApoB testing isn’t part of a standard lipid panel and not everyone needs it. But it can be useful when your standard numbers look borderline or conflicting. For example, if your LDL is technically normal but your triglycerides are elevated, your particle count could still be high. Non-HDL cholesterol captures some of this same information without an extra test, which is why many clinicians have started paying more attention to it as a single, easy-to-calculate number that tells more than LDL alone.
