For most adults, a healthy total cholesterol level is below 200 mg/dL, with LDL (often called “bad” cholesterol) below 100 mg/dL and HDL (“good” cholesterol) at 60 mg/dL or higher. But those numbers aren’t one-size-fits-all. Your ideal targets depend on your age, sex, and whether you have risk factors like diabetes or existing heart disease.
The Numbers on Your Lipid Panel
A standard cholesterol test measures four things. Here’s what healthy levels look like for most adults age 20 and older:
- Total cholesterol: Below 200 mg/dL
- LDL cholesterol: Below 100 mg/dL
- HDL cholesterol: 60 mg/dL or higher is ideal
- Triglycerides: Below 150 mg/dL
Your results will also include non-HDL cholesterol, which is simply your total cholesterol minus your HDL. This number captures all the cholesterol types that can build up in your arteries. A healthy non-HDL level is below 130 mg/dL.
Total cholesterol between 200 and 239 is considered borderline high, and 240 or above is high. For LDL specifically, anything from 100 to 159 is elevated, and 160 or higher is considered dangerous for most people. These categories matter because the higher your LDL climbs, the more cholesterol gets deposited in artery walls, gradually narrowing them.
HDL Targets Differ by Sex
HDL is the one number where higher is better. It works like a cleanup crew, carrying excess cholesterol from your bloodstream back to the liver for disposal. The minimum healthy HDL floor is different for men and women: men should stay above 40 mg/dL, while women should stay above 50 mg/dL. For both, 60 mg/dL or higher offers the most protection.
This sex-based difference is the only one in the standard adult lipid panel. Total cholesterol, LDL, and triglyceride targets are the same for men and women.
Targets for Children and Teens
Children and adolescents (age 19 and younger) have tighter thresholds than adults:
- Total cholesterol: Below 170 mg/dL is acceptable; 170 to 199 is borderline; above 200 is high
- LDL cholesterol: Below 110 mg/dL is acceptable; 110 to 129 is borderline; above 130 is high
- HDL cholesterol: Above 45 mg/dL
The American Academy of Pediatrics recommends a first cholesterol screening between ages 9 and 11, with follow-up testing every five years. Earlier screening may be recommended if a child has a family history of high cholesterol or early heart disease.
When Your Target LDL Should Be Lower
The general goal of LDL below 100 mg/dL applies to people at low cardiovascular risk. If your risk is higher, your target drops significantly.
Doctors now estimate your 10-year risk of a heart attack or stroke using a calculation that factors in your age, blood pressure, cholesterol, kidney function, and other variables. Based on that score, targets shift:
- Borderline or intermediate risk (3% to under 10%): LDL below 100 mg/dL
- High risk (10% or greater): LDL below 70 mg/dL
- Existing heart disease: LDL below 55 mg/dL
That lowest target of 55 mg/dL may sound extreme, but it reflects strong clinical trial evidence. The 2026 guidelines from the American Heart Association and American College of Cardiology now recommend this goal for anyone with established cardiovascular disease, whether they’ve had a heart attack, stroke, or have significant artery blockages. People with very high LDL (190 mg/dL or above) who also have inherited cholesterol disorders or coronary artery calcification are held to a target of below 70 mg/dL even if they haven’t had an event yet.
Conditions like diabetes and high blood pressure push your risk category higher, which in turn pushes your LDL goal lower. If you have one or more of these risk factors, your doctor will likely set a more aggressive target than the standard 100 mg/dL.
What Your Cholesterol Ratio Tells You
You can get a rough sense of your cardiovascular risk by dividing your total cholesterol by your HDL. If your total is 200 and your HDL is 50, your ratio is 4 to 1. A lower ratio is better because it means a larger share of your cholesterol is the protective HDL type. Most doctors consider a ratio above 5 to 1 concerning, though the individual numbers on your panel are generally more useful for guiding treatment decisions than the ratio alone.
Beyond Standard LDL Testing
Standard LDL measurement has a blind spot. It estimates the amount of cholesterol inside LDL particles, but it doesn’t count the particles themselves. Two people with the same LDL number can have very different numbers of particles floating in their blood, and it’s the particle count that drives artery damage.
A blood test called apolipoprotein B (apoB) measures something closer to that particle count, since each artery-clogging particle carries exactly one apoB protein on its surface. It also captures risk from other harmful particles that standard LDL testing misses entirely. ApoB doesn’t require fasting, and it’s more accurate at lower cholesterol levels, which matters if you’re already on treatment and trying to confirm you’ve hit your target.
ApoB targets generally mirror LDL targets: below 100 mg/dL for moderate-risk individuals, below 70 mg/dL for high-risk, and below 55 mg/dL for very-high-risk patients. An apoB level of 130 mg/dL or above is considered a risk-enhancing factor that may tip the scales toward starting cholesterol-lowering treatment. Not every doctor orders this test routinely, but it can be especially informative if your triglycerides are high, you have diabetes, or your standard LDL seems low yet your risk profile suggests otherwise.
How Often to Get Tested
Screening frequency depends on your age and sex. After an initial test in childhood, adults between 20 and 44 (men) or 20 and 54 (women) generally need testing every five years if their levels are normal. The schedule tightens to every one to two years for men aged 45 to 65 and women aged 55 to 65. After 65, annual testing is recommended for everyone.
More frequent testing makes sense if your numbers are borderline, you’ve recently started medication, or you have risk factors like a family history of early heart disease. Your doctor may also want to recheck sooner after major lifestyle changes to see whether diet and exercise have moved your numbers.
Preparing for a Cholesterol Test
You may need to fast for 8 to 12 hours before your blood draw, depending on what your doctor orders. Fasting primarily affects triglyceride accuracy, since eating a meal can temporarily spike triglyceride levels and throw off related calculations. Some newer guidelines allow non-fasting panels for initial screening, but if your triglycerides come back elevated on a non-fasting test, you’ll likely be asked to repeat it fasted. Water is fine during the fasting window.
