Total and non-HDL cholesterol: normal and optimal levels

Total cholesterol is all the cholesterol in your blood. Non-HDL cholesterol is that total minus your HDL ("good") cholesterol: the cholesterol carried by LDL and the other particles that can build plaque in your arteries. Your lab gets it by simple subtraction. It tracks heart risk better than total cholesterol, and in people on statins it tracked risk slightly better than LDL did.¹²³

The short version

• Normal: for adults, the U.S. desirable levels are total cholesterol under 200 mg/dL and non-HDL under 130 mg/dL. For people 19 and younger they're under 170 and under 120.⁴⁵
• High is common. A total of 240 or more counts as high, and about 1 in 9 U.S. adults is there.⁵⁶ The usual reasons are diet, extra weight, insulin resistance and the genes you inherited; less often an underactive thyroid, kidney disease or a medicine.⁴⁵
• Very high (non-HDL 220 or more, or LDL 190 or more) often means an inherited condition such as familial hypercholesterolemia. See a clinician soon, and your close relatives should get tested too.¹⁵
• Read the two together. A high total with a normal non-HDL usually means your HDL is high. A high non-HDL is the number linked to heart attacks and strokes.⁴⁷

What total and non-HDL cholesterol are

Cholesterol is a waxy fat your body uses to build cell walls and hormones. It travels through your blood inside particles called lipoproteins, and your lipid panel sorts them into two families.⁴

• HDL (high-density lipoprotein) picks up extra cholesterol and carries it back to your liver. That's why it's called "good" cholesterol.⁹
• Everything else carries cholesterol out into the body: LDL, VLDL, IDL, the leftover "remnants" of triglyceride-rich particles, and Lp(a). Each of these particles carries exactly one ApoB protein, and each can push cholesterol into an artery wall.⁸⁹

Total cholesterol adds up both families. Non-HDL cholesterol keeps only the second one:

non-HDL = total cholesterol − HDL

Labs measure total cholesterol, HDL and triglycerides directly, so non-HDL costs nothing extra.¹ It's the same as LDL cholesterol plus the cholesterol in remnants and Lp(a).¹ That's its advantage: when triglycerides run high, extra cholesterol rides in VLDL and remnants that the LDL number misses. U.S. guidelines made non-HDL a second treatment target for exactly that reason, in people with triglycerides of 200 mg/dL or more.⁵

What's a normal total and non-HDL cholesterol?

Start with the flag on your own report. Then know this: for cholesterol, "normal" means healthy, not typical. Most lab tests are flagged when they fall outside the middle 95% of a reference group. Lipid experts ask labs to flag cholesterol at the "desirable" levels set by heart guidelines instead, and in much of Europe a typical level is already past that line.¹

• U.S. desirable levels for adults are a total under 200 mg/dL and a non-HDL under 130 mg/dL. For people 19 and younger they're under 170 and under 120.⁴ The National Cholesterol Education Program calls a total of 200–239 borderline high and 240 or more high.⁵ In 2021–2023, 11.3% of U.S. adults had a total of 240 or more.⁶
• European lab flags draw the lines a little differently: a total of 190 mg/dL or more and a non-HDL of 150 or more on a non-fasting test. In a typical Western or Northern European country, 72% of adults would get a flag on total cholesterol and 50% on non-HDL.¹

Men and women differ over a lifetime. Cholesterol tends to rise with age. Between 20 and 39, men are more likely than women to have a high total; after menopause, a woman's risk goes up.⁴

"Optimal" total and non-HDL cholesterol: what health optimizers aim for

For non-HDL, optimizers and cardiologists agree on the direction: lower is better. They differ on how low to go. Here's the ladder, from strictest to loosest non-HDL target. The targets are the same for men and women.

Your own goal depends on your risk. For people already at high risk, such as those with heart disease or diabetes, U.S. guidelines as summarized by the National Lipid Association act on a non-HDL above 100 mg/dL, and above 85 at very high risk.⁸

Why the low targets hold up:

• In 398,846 people from 38 cohorts, followed for up to 43 years, the 30-year rate of a coronary event or ischemic stroke climbed from 7.7% to 33.7% in women and from 12.8% to 43.6% in men between a non-HDL under 100 and one of 220 or more. Only 5.1% of the participants were under 100.⁷
• In almost 900,000 adults, each 39 mg/dL (1 mmol/L) lower total cholesterol went with about half the risk of dying of heart disease at ages 40–49, a third less at 50–69 and a sixth less at 70–89, with no threshold where the benefit stopped.²
• Worldwide, high non-HDL cholesterol caused an estimated 3.9 million deaths in 2017, a third of all deaths from coronary heart disease and ischemic stroke.¹⁰

Enlarge

Keep "optimal" in perspective: these are targets, not diagnoses. A non-HDL of 145 is a reason to look at your diet, weight, blood sugar and family history. The app's functional band for total cholesterol has a floor: a total under 160 shows as in range, not optimal.¹² Lower isn't better for everything, either. In the same 900,000 adults, at ages 70–89 and in people with a systolic blood pressure over about 145, a higher total went with fewer deaths from bleeding strokes.²

What a high total or non-HDL usually means

The size of the rise is the first clue. U.S. guidelines set a non-HDL goal 30 mg/dL above each LDL goal, on the premise that up to 30 mg/dL of VLDL cholesterol is normal. Adding that 30 to the LDL categories gives a scale for non-HDL.⁵

The usual suspects

• Diet. Saturated fat is the main driver. It's high in red meat, full-fat dairy, some baked goods, and fried and processed foods.⁴
• Extra weight, too little activity and insulin resistance. Weight tends to push cholesterol up. High triglycerides show up most often with the metabolic syndrome, and that pattern raises non-HDL more than it raises LDL.⁴⁵⁸
• Genes. High cholesterol runs in families.⁴ The strongest inherited form, familial hypercholesterolemia, affects about 1 in 311 people.¹³
• Age and menopause. Levels rise with age, and a woman's go up after menopause.⁴
• Smoking raises non-HDL.⁹

Less common: other conditions and medicines

Guidelines ask clinicians to check for these before treating a high result: diabetes, an underactive thyroid, liver disease that blocks bile flow, chronic kidney disease, and medicines such as corticosteroids, anabolic steroids and progestins. Estrogens, retinoids and higher doses of beta-blockers mainly raise triglycerides.⁵ An underactive thyroid slows the liver's LDL clearance. In one study of 8,795 patients, about 1 in 20 of those with high cholesterol had a high TSH.¹⁴ Don't stop a prescribed medicine on your own. Bring your full list to your clinician.

Very high (non-HDL 220 or more): think inherited

People with an LDL of 190 mg/dL or more usually have a genetic form of high cholesterol, and family testing is important.⁵ European lab experts ask labs to refer these results on, and a non-HDL of 220 or more is a clue to an inherited or secondary cause.¹

Get care now for chest pain or pressure, shortness of breath, or pain spreading to your arm, back, neck or jaw: call 911, even if you're unsure it's a heart attack.¹⁵ See a clinician soon for a non-HDL of 220 or more, an LDL of 190 or more, or triglycerides over 880 mg/dL, which raise the risk of pancreatitis.¹

Is a low result a problem?

Usually not, at least for your arteries. The large cohort data found no threshold below which lower total cholesterol stopped tracking lower heart-disease death.² The one known trade-off is the bleeding-stroke finding in older adults with high blood pressure, above.²

Total and non-HDL read best next to their neighbors

The pattern across your lipid panel usually says more than either number alone:⁵⁸

When LDL and non-HDL disagree, heart risk usually follows the non-HDL or an ApoB test, which counts the plaque-building particles directly.⁸

How fast cholesterol changes

Cholesterol moves on three clocks: hours, days and weeks.

Enlarge

• Hours: a meal barely moves it. In large population studies, total and non-HDL were at most about 8 mg/dL lower 1–6 hours after a normal meal, and triglycerides about 26 higher. The small drop comes from the fluid you drink. Most people can be tested without fasting.¹
• Days: medicines work fast. In a small study of 10 men who stopped their statin, total cholesterol was 18% higher by day 4 and 48% higher by days 7–15. It was back to baseline within 20 days of restarting.¹⁶ Don't stop a statin to "test" this.
• Weeks: the recheck window. U.S. guidelines recheck lipids 4 to 12 weeks after starting or changing a statin, then every 3 to 12 months as needed.¹⁷
• Trends beat snapshots. Note whether each test was fasting: a meal moves triglycerides about three times as much as it moves cholesterol.¹

Going deeper: the arithmetic inside your lipid panel

Enlarge

Your lab measures three things (total cholesterol, HDL and triglycerides) and calculates the rest:¹

non-HDL = total − HDL

LDL (Friedewald) = total − HDL − triglycerides ÷ 5

The triglycerides ÷ 5 term estimates the cholesterol in VLDL. Newer LDL formulas handle high triglycerides better, because the cholesterol load of VLDL varies.⁸ Non-HDL skips that estimate entirely.

Remnant cholesterol is total − HDL − LDL: the cholesterol in the triglyceride-rich particles.¹ Lp(a) cholesterol (about 30% of Lp(a)'s mass) is counted inside total, non-HDL and LDL alike.¹

The total-to-HDL ratio was the single strongest cholesterol predictor of heart-disease death in the 900,000-adult analysis: 40% more informative than non-HDL and more than twice as informative as total cholesterol.² The Libby app shows it with an optimal band of 3.5 or less.¹²

ApoB versus non-HDL. Each plaque-building particle carries one ApoB, so ApoB counts particles while non-HDL weighs their cholesterol. With high triglycerides, extra weight or insulin resistance, LDL particles get smaller and carry less cholesterol. Then LDL can look fine while ApoB stays high.⁸

Questions worth asking

• What is my non-HDL goal, given my own heart risk?
• Is my total high because of my HDL or because of my non-HDL?
• What do my triglycerides and LDL show next to it, and would an ApoB test help?
• Should I be checked for diabetes, thyroid or kidney problems?
• Could this be inherited, and should my family be tested?
• When should we recheck it, and does it need to be fasting?

FAQ

What is a normal non-HDL cholesterol? Under 130 mg/dL for adults and under 120 for people 19 and younger. People at high heart risk usually aim lower.⁴⁸

Is non-HDL cholesterol better than total cholesterol? For heart risk, yes. Total includes HDL, and in a study of about 900,000 adults, non-HDL and the total-to-HDL ratio both predicted heart-disease death better than total cholesterol did.²

Do I need to fast for a cholesterol test? Usually no. A normal meal lowers total and non-HDL by at most about 8 mg/dL on average. Your clinician may still ask you to fast, for example after a triglyceride result over 440.¹

Can my total cholesterol be high while my non-HDL is normal? Yes. Total includes HDL, so a high HDL can push the total over 200 while the plaque-building part stays in range.⁴
