Quick Answer
A lipid panel reports several numbers at once — see the general reference ranges for total cholesterol, LDL, HDL, and triglycerides, and why your personal target can differ.
In this article
A lipid panel reports several numbers together — total cholesterol, LDL, HDL, and triglycerides — and a "normal" result depends on looking at the full picture rather than any single value in isolation.
Quick Answer
For most adults, general reference points are: total cholesterol below 200 mg/dL (5.2 mmol/L), LDL ("bad") cholesterol below 100 mg/dL (2.6 mmol/L), HDL ("good") cholesterol of 60 mg/dL (1.6 mmol/L) or higher, and triglycerides below 150 mg/dL (1.7 mmol/L). These are general population reference ranges, not personal treatment targets — the LDL level that's actually right for you depends on your overall cardiovascular risk, which only a doctor can assess using your full history.
Cholesterol Levels Chart
| Marker | General interpretation | Notes |
|---|---|---|
| Total cholesterol: below 200 mg/dL (below 5.2 mmol/L) | Desirable | General population reference |
| Total cholesterol: 200–239 mg/dL (5.2–6.2 mmol/L) | Borderline high | |
| Total cholesterol: 240 mg/dL or above (6.2 mmol/L or above) | High | |
| LDL ("bad") cholesterol: below 100 mg/dL (below 2.6 mmol/L) | Optimal for many adults | A personal LDL goal may be lower if you're at higher cardiovascular risk |
| LDL cholesterol: 100–129 mg/dL (2.6–3.3 mmol/L) | Near optimal | |
| LDL cholesterol: 130–159 mg/dL (3.4–4.1 mmol/L) | Borderline high | |
| LDL cholesterol: 160–189 mg/dL (4.1–4.9 mmol/L) | High | |
| LDL cholesterol: 190 mg/dL or above (4.9 mmol/L or above) | Very high | |
| HDL ("good") cholesterol: 60 mg/dL or above (1.6 mmol/L or above) | Protective | Unlike the other markers, higher HDL is generally better |
| HDL cholesterol: below 40 mg/dL for men / below 50 mg/dL for women (below 1.0 / 1.3 mmol/L) | Low — a risk factor | |
| Triglycerides: below 150 mg/dL (below 1.7 mmol/L) | Normal | |
| Triglycerides: 150–199 mg/dL (1.7–2.2 mmol/L) | Borderline high | |
| Triglycerides: 200–499 mg/dL (2.3–5.6 mmol/L) | High | |
| Triglycerides: 500 mg/dL or above (5.6 mmol/L or above) | Very high | Also carries a risk of pancreatitis, separate from cardiovascular risk |
| Non-HDL cholesterol: below 130 mg/dL (below 3.4 mmol/L) | General reference goal | A secondary number some clinicians track alongside LDL |
These are general reference values, not a universal pass/fail test — the sections below explain what they mean together.
What Do the Different Cholesterol Numbers Mean?
- Total cholesterol adds up LDL, HDL, and a portion of triglycerides into one number. It's a starting point, not the full picture.
- LDL ("bad") cholesterol — see our LDL cholesterol guide for the normal range in detail. Too much LDL contributes to plaque buildup inside artery walls.
- HDL ("good") cholesterol — see our HDL cholesterol guide. HDL helps clear excess cholesterol from the bloodstream.
- Triglycerides — a different type of blood fat, not cholesterol itself. Our triglycerides guide covers what raises them.
- Non-HDL cholesterol (total cholesterol minus HDL) captures LDL plus other potentially harmful particles in one number; some clinicians use it alongside or instead of LDL.
- Cholesterol ratio (total cholesterol divided by HDL) is sometimes reported, but most current guidance focuses on the individual numbers — LDL, HDL, triglycerides, and non-HDL — rather than a single ratio.
What Is a Normal LDL Level?
A general reference range: below 100 mg/dL (2.6 mmol/L) is considered optimal for many adults. But this one number isn't the same for everyone:
- General reference range — below 100 mg/dL is a commonly used starting point for the general population.
- Treatment targets — current cardiology guidance has moved away from a single universal "normal" LDL number toward individualized treatment targets based on risk.
- Individual risk-based targets — your personal LDL goal depends on factors such as age, existing heart disease, a prior heart attack or stroke, diabetes, kidney disease, and other risk factors. For some people at very high cardiovascular risk, a doctor may set a goal below 70 mg/dL, or even below 55 mg/dL — well below the general population reference range.
This is why two people can have the identical LDL number and receive different advice from their doctors — the number alone doesn't determine the target; your overall risk does.
What Is a Normal HDL Level?
An HDL of 60 mg/dL (1.6 mmol/L) or higher is generally considered protective, while below 40 mg/dL for men or below 50 mg/dL for women — roughly 1.0 or 1.3 mmol/L — is considered a risk factor. Unlike LDL, higher HDL is usually favorable rather than something to stay under.
That said, HDL isn't interpreted alone. A high HDL doesn't cancel out a high LDL, and HDL is only one part of the overall cardiovascular risk picture alongside LDL, triglycerides, and non-HDL cholesterol. See our HDL cholesterol guide for what influences it.
What Is a Normal Triglyceride Level?
Below 150 mg/dL (1.7 mmol/L) is generally considered normal, 150–199 mg/dL (1.7–2.2 mmol/L) borderline high, 200–499 mg/dL (2.3–5.6 mmol/L) high, and 500 mg/dL (5.6 mmol/L) or above very high. Very high triglycerides also carry a risk of pancreatitis, separate from cardiovascular risk. Our triglycerides guide covers what typically raises them and how they're managed.
Normal Cholesterol Levels by Age and Sex
Cholesterol naturally changes over a lifetime. LDL in particular tends to rise gradually through adulthood for many people, and women often see a rise in LDL after menopause as estrogen — which has a protective effect on lipid levels — declines. Sex also factors into the HDL reference ranges above, which use a different threshold for men and women.
MedlinePlus, the US National Library of Medicine's consumer health service, gives these healthy levels by age group and sex:
| Group | Total cholesterol | Non-HDL cholesterol | LDL cholesterol | HDL cholesterol |
|---|---|---|---|---|
| Anyone age 19 or younger | Less than 170 mg/dL | Less than 120 mg/dL | Less than 110 mg/dL | More than 45 mg/dL |
| Men age 20 or older | Less than 200 mg/dL | Less than 130 mg/dL | Less than 100 mg/dL | 60 mg/dL or higher is best; below 40 mg/dL is low |
| Women age 20 or older | Less than 200 mg/dL | Less than 130 mg/dL | Less than 100 mg/dL | 60 mg/dL or higher is best; below 50 mg/dL is low |
For adults, these healthy targets don't change from one decade to the next — there is no separate "normal" number for a 40-year-old and a 60-year-old. What changes with age is how your results are interpreted: your overall cardiovascular risk, family history, and other conditions all matter, and a doctor may set a lower LDL goal if your risk is higher. A normal triglyceride level is below 150 mg/dL.
How Often Should You Have Your Cholesterol Checked?
General recommendations from MedlinePlus, which a doctor may adjust for your risk factors and family history:
- Children: at least once between ages 9 and 11, and again between 17 and 21 — some children are tested from age 2 if there is a family history of high cholesterol, heart attack, or stroke
- Adults aged 21 to 65: every 5 years
- Men aged 45 to 65 and women aged 55 to 65: every 1 to 2 years
- Over 65: every year
What Can Change Your Cholesterol Levels?
Many factors influence cholesterol and triglyceride levels, including:
- Diet — particularly saturated and trans fat intake, and added sugar for triglycerides specifically
- Body weight — excess weight, especially around the abdomen, is linked to higher LDL and triglycerides and lower HDL
- Physical activity — regular aerobic exercise tends to raise HDL and can help lower triglycerides
- Genetics — some people have a strong genetic tendency toward high cholesterol (familial hypercholesterolemia) regardless of lifestyle
- Age — see above
- Smoking — lowers HDL and damages blood vessel walls
- Alcohol — excess alcohol can raise triglycerides significantly
- Diabetes and metabolic conditions — often raise triglycerides and lower HDL
- Thyroid disease — an underactive thyroid can raise LDL
- Medications — certain medications can affect lipid levels as a side effect
- Other medical conditions — including kidney and liver disease
Our how to lower cholesterol guide covers which of these changes have the strongest evidence behind them.
Do You Need to Fast Before a Cholesterol Test?
Most routine lipid panels today don't require fasting beforehand — non-fasting testing is now considered a valid option for general cardiovascular risk screening in adults by major cardiology guidance. Fasting is still sometimes requested for specific situations, such as very high triglycerides, a history of pancreatitis, or when a doctor wants the most precise triglyceride reading, since triglycerides specifically are affected by recent food intake in a way LDL and HDL are not. If your doctor asks you to fast, that's usually about getting the most accurate triglyceride number, not because a non-fasting test is inaccurate for the other markers.
How to Read a Cholesterol Test
A practical way to look at your results:
1. Look at LDL — your "bad" cholesterol number 2. Look at HDL — your "good" cholesterol number 3. Look at triglycerides — a different type of blood fat, checked at the same time 4. Consider non-HDL and total cholesterol — the combined picture 5. Consider your overall cardiovascular risk — age, blood pressure, diabetes, smoking, family history, and prior cardiovascular events all factor in alongside the numbers themselves 6. Discuss abnormal or concerning results with a clinician rather than interpreting them in isolation — this guide can't diagnose your individual results or tell you what they specifically mean for you
When Is Cholesterol Considered High?
"High cholesterol" usually isn't about one number alone. A high total cholesterol driven mainly by a high HDL is a different situation from the same total driven by a high LDL. Doctors look at the full lipid panel — LDL, HDL, triglycerides, and non-HDL — together with your broader cardiovascular risk factors, rather than treating any single number as the whole story.
What If Your Cholesterol Is Abnormal?
An abnormal result typically leads to some combination of the following, rather than an immediate prescription:
- Repeat testing when appropriate, since a single result can be affected by recent illness, food, or lab variation
- A review of lifestyle and medical history, including diet, activity, weight, smoking, and alcohol use
- An overall cardiovascular risk assessment, not just the cholesterol numbers alone
- Looking for secondary causes where appropriate, such as thyroid or kidney disease, diabetes, or certain medications
- A discussion of treatment options if indicated, which may include lifestyle changes alone or alongside medication — see our high cholesterol symptoms guide for why most people don't notice anything and only find out through testing

Frequently Asked Questions
What is a healthy total cholesterol level?
Generally, below 200 mg/dL (5.2 mmol/L) is considered desirable for adults, though the breakdown of LDL, HDL, and triglycerides matters more for assessing cardiovascular risk than the total number alone.
What is a normal LDL level?
Below 100 mg/dL (2.6 mmol/L) is a commonly used general reference point, but your personal LDL target depends on your overall cardiovascular risk — people at higher risk are often given a lower goal by their doctor.
What is a healthy HDL level?
60 mg/dL (1.6 mmol/L) or higher is generally considered protective, while below 40 mg/dL for men or below 50 mg/dL for women is considered a risk factor. Unlike LDL, higher HDL is usually favorable.
What is a normal triglyceride level?
Below 150 mg/dL (1.7 mmol/L) is considered normal, 150–199 mg/dL borderline high, and 200 mg/dL or above high. Very high levels (500 mg/dL or above) also carry a risk of pancreatitis.
Is a cholesterol level of 250 mg/dL high?
A total cholesterol of 250 mg/dL falls in the range generally classified as high (240 mg/dL and above). But what this means for you depends on the LDL, HDL, and triglyceride breakdown behind that number, not the total alone — a doctor can interpret it properly alongside your other results.
Do I need to fast before a cholesterol test?
Usually not — non-fasting testing is now considered valid for general cholesterol screening in adults. A doctor may still ask you to fast in specific situations, such as to get the most accurate triglyceride reading.
Can my cholesterol be normal while my LDL is high?
Yes — total cholesterol combines LDL, HDL, and a portion of triglycerides, so a high HDL can keep the total number in a range that looks normal even while LDL itself is elevated. This is exactly why doctors look at the full breakdown, not just the total.
What matters more, total cholesterol or LDL?
LDL and the other individual numbers (HDL, triglycerides, non-HDL) generally give more useful information than total cholesterol alone, since total cholesterol can look similar in very different underlying situations.
Does age affect cholesterol levels?
Yes — LDL in particular tends to rise gradually with age, and women often see a rise after menopause. Healthy targets differ between young people (19 or younger: total cholesterol below 170 mg/dL, LDL below 110 mg/dL) and adults (20 or older: total below 200 mg/dL, LDL below 100 mg/dL), but they don't change from one adult decade to the next. A doctor interprets your results alongside your age, sex, and overall cardiovascular risk.
Can high cholesterol cause symptoms?
Almost never on its own — high cholesterol is typically silent and found through a blood test, not by how you feel. Rare visible signs can occur with very high, long-standing cholesterol, but a blood test remains the only reliable way to know your levels.
When should I talk to a doctor about my cholesterol results?
Whenever your results fall outside the general reference ranges, when your doctor recommends it based on your personal risk factors, or whenever you have questions about what your specific numbers mean for you — a lipid panel is only useful once it's interpreted alongside your full health picture.
