Cholesterol: Normal Ranges, LDL, HDL, Triglycerides, and When to See a Doctor

Quick Answer
Cholesterol isn't one number. Here are the normal ranges for LDL, HDL, triglycerides and non-HDL, what high or low results actually mean, and when it's worth talking to a doctor.

Cholesterol is a waxy, fat-like substance the body needs to build cells and produce certain hormones. The liver makes all the cholesterol the body actually needs — the rest comes from diet, and having too much of the wrong type circulating in the blood is what raises health risk.
Quick Answer
Cholesterol isn't one single number. A standard lipid panel reports total cholesterol, LDL ("bad"), HDL ("good"), and triglycerides together, and sometimes non-HDL cholesterol as well. For most adults, general reference points are total cholesterol below 200 mg/dL, LDL below 100 mg/dL, HDL of 60 mg/dL or higher, and triglycerides below 150 mg/dL — but these are general population reference ranges, not personal treatment targets. High cholesterol itself has no symptoms, so a blood test is the only way to know. It's worth discussing any result outside these ranges with a doctor, who interprets your numbers alongside your overall cardiovascular risk.
LDL, HDL, Triglycerides, and Non-HDL: Not All Cholesterol Is the Same
A lipid panel reports several related but different numbers:
- LDL (low-density lipoprotein) — often called "bad" cholesterol, since too much contributes to plaque buildup in artery walls. Our LDL cholesterol guide covers the normal range and why your personal target may differ from the general reference.
- HDL (high-density lipoprotein) — often called "good" cholesterol, since it helps remove excess cholesterol from the bloodstream. Our HDL cholesterol guide covers what a high or low HDL actually means.
- Triglycerides — a different type of blood fat, not cholesterol itself, measured on the same panel. 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 track it alongside or instead of LDL.
- Total cholesterol adds LDL, HDL, and a portion of triglycerides into one number — a starting point, not the full picture on its own.
Normal Cholesterol Ranges
| Marker | General reference | Notes |
|---|---|---|
| Total cholesterol | Below 200 mg/dL (5.2 mmol/L) desirable; 200–239 mg/dL borderline high; 240 mg/dL or above high | General population reference |
| LDL ("bad") | Below 100 mg/dL (2.6 mmol/L) optimal for many adults; 190 mg/dL or above very high | A personal LDL goal may be lower if you're at higher cardiovascular risk |
| HDL ("good") | 60 mg/dL (1.6 mmol/L) or higher protective; below 40 mg/dL (men) or below 50 mg/dL (women) a risk factor | Unlike the other markers, higher HDL is generally better |
| Triglycerides | Below 150 mg/dL (1.7 mmol/L) normal; 500 mg/dL or above very high | Very high levels also carry a risk of pancreatitis |
| Non-HDL cholesterol | Below 130 mg/dL (3.4 mmol/L) general reference goal | A secondary number some clinicians track alongside LDL |
These are general reference values for the population, not a universal pass/fail test or a personal treatment target. Our normal cholesterol levels guide has the complete chart, including the borderline and intermediate ranges, and explains how the numbers fit together.
What High or Low Results Mean
A result outside the general range doesn't have one single meaning on its own:
- High LDL or total cholesterol contributes to plaque buildup in artery walls over time (atherosclerosis), raising the risk of heart attack and stroke. How much it matters for you depends on your overall cardiovascular risk, not the number alone.
- Low HDL is an independent cardiovascular risk factor, separate from LDL. A high HDL, on the other hand, isn't automatically more protective past a certain point — current evidence doesn't support treating a very high HDL as extra protection.
- High triglycerides are often linked to diet, weight, alcohol use, or poorly controlled diabetes, and very high levels carry a risk of pancreatitis in addition to cardiovascular risk.
- A single abnormal result can sometimes reflect recent illness, food, or lab variation rather than your usual level, which is why doctors often repeat an abnormal test before acting on it.
See our high cholesterol symptoms guide for why most people don't notice anything at all, whatever their results show.
Why It's Called Silent
Like high blood pressure, high cholesterol typically causes no symptoms at all — it's discovered through a blood test, not by how you feel. Left unaddressed over years, it contributes to atherosclerosis (plaque buildup in arteries), raising the risk of heart attack and stroke.
Testing: The Lipid Panel
A lipid profile blood test — measuring total cholesterol, LDL, HDL, and triglycerides together — is the standard way cholesterol is checked. Most routine lipid panels today don't require fasting beforehand; fasting is mainly requested when the most accurate triglyceride reading is needed, since triglycerides (unlike LDL and HDL) are affected by recent food intake.
When to Discuss Your Results with a Doctor
It's worth discussing your lipid panel with a doctor whenever:
- Any result falls outside the general reference ranges above
- You have other cardiovascular risk factors, such as high blood pressure, diabetes, smoking, or a family history of early heart disease
- A result is unexpectedly abnormal and your doctor recommends repeating the test
- You have questions about what your specific numbers mean for you, since the general ranges aren't the same as a personal treatment target
A lipid panel is most useful interpreted alongside your overall health picture, not read in isolation. Our how to lower cholesterol guide covers the lifestyle changes with the strongest evidence behind them once you've discussed your results.

HDL Cholesterol: Normal Levels, Low and High HDL, and What Your Results Mean
HDL is often called "good" cholesterol, but it's not as simple as "the higher, the better" — here's what a normal level actually means.
How to Lower Cholesterol
Diet and lifestyle changes can meaningfully improve cholesterol levels — here's what has the strongest evidence behind it.
LDL Cholesterol: Normal Range
LDL cholesterol is the type most directly linked to artery plaque buildup — here's what counts as a healthy level and why targets vary by individual risk.
Normal Cholesterol Levels: LDL, HDL, Total Cholesterol, and Triglycerides
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.
Symptoms of High Cholesterol
High cholesterol is almost always symptomless — which is exactly why testing, not how you feel, is how it's found. Here's what rare visible signs can look like.
Triglycerides: Normal Range and Causes of High Levels
Triglycerides are a different type of blood fat from cholesterol, but they're checked together — here's what a normal level looks like and what raises it.
Frequently Asked Questions
What is a normal cholesterol level?
For most adults, general reference points are total cholesterol below 200 mg/dL, LDL below 100 mg/dL, HDL of 60 mg/dL or higher, and triglycerides below 150 mg/dL. These are general population reference ranges; your personal target depends on your overall cardiovascular risk, which a doctor assesses individually.
What is the difference between LDL and HDL?
LDL ("bad" cholesterol) carries cholesterol to tissues, and too much contributes to plaque buildup in artery walls. HDL ("good" cholesterol) helps move excess cholesterol out of the bloodstream back to the liver for removal. Both are measured because each gives separate information about cardiovascular risk.
What are triglycerides, and are they the same as cholesterol?
Triglycerides are a different type of blood fat, not cholesterol itself, but they're measured on the same lipid panel. Excess calories the body doesn't use immediately are converted to triglycerides and stored in fat cells.
What is non-HDL cholesterol?
Non-HDL cholesterol is your total cholesterol minus your HDL. It captures LDL plus other potentially harmful particles in a single number, and some clinicians use it alongside or instead of LDL when assessing risk.
Can high cholesterol cause symptoms?
Almost never. High cholesterol is typically silent and is found through a blood test, not by how you feel. It's one of the most important things to understand about it.
When should I discuss my cholesterol results with a doctor?
Discuss your lipid panel with a doctor whenever a result falls outside the general reference ranges, you have other cardiovascular risk factors such as high blood pressure or diabetes, a result is unexpectedly abnormal, or you have questions about what your specific numbers mean for you.
