On This Page – Quick Medical Summary
Your results are open, and the chart you just found gives a different range than the one printed on your own report. Both are right, and that is the part nobody explains.
There is no single set of normal lipid panel results. Three kinds of number are in play: the range your lab printed beside your result, the desirable level published by health authorities, and the goal your clinician may be working toward for you.
Where to start. For the published levels for all five values, read on; if your report’s range disagrees with what you found online, that is section four. If you have a cholesterol diagnosis or take medication for it, the section on goals applies.
Reading a parent’s report? The same distinctions hold, and how the panel is assembled covers which values were measured.

The five levels most reports are read against
A standard lipid panel reports five values — total cholesterol, LDL, triglycerides, HDL and non-HDL cholesterol — according to the 2026 dyslipidemia guideline summarised on the NIH Bookshelf. Below are the healthy levels the National Library of Medicine publishes for each.
| Value | Adults 20 and older | Age 19 and younger | Source |
|---|---|---|---|
| Total cholesterol | Less than 200 mg/dL | Less than 170 mg/dL | MedlinePlus, Oct 2024 |
| LDL cholesterol | Less than 100 mg/dL | Less than 110 mg/dL | MedlinePlus, Oct 2024 |
| Non-HDL cholesterol | Less than 130 mg/dL | Less than 120 mg/dL | MedlinePlus, Oct 2024 |
| HDL cholesterol | Above 60 mg/dL desired; under 40 listed as low for men | Above 45 mg/dL | MedlinePlus, Oct 2024, Jan 2025 |
| Triglycerides | Less than 150 mg/dL | Differs — ask the child’s provider | MedlinePlus, Dec 2024 |

What the published tables leave out
Two gaps are worth naming, because you will notice them and assume the fault is yours. The MedlinePlus results tables carry no triglyceride row — that value has its own page and scale — and the table for women aged 20 and older carries no HDL row.
The line that says “calculated”
Your LDL may be labelled calculated, meaning it was estimated from your total cholesterol, HDL and triglycerides rather than measured. That is standard, and your LDL was estimated rather than measured explains what the estimate rests on.
If the non-HDL line is unfamiliar, the number most reports print without explaining covers it, and what each value actually is covers the rest.
The three standards behind the word normal
The levels above are one kind of number. Your report carries a second, and your clinician may be working from a third. Telling them apart is the whole job.
| Kind of number | Where it comes from | Who it applies to | Can you compare it? |
|---|---|---|---|
| Reference range | Your lab, from large groups of healthy people, using its own method | Anyone tested at that lab | No — not across labs, not against a chart |
| Desirable level | Health authorities, as a risk threshold | Everyone in the published age or sex group | Yes — published nationally |
| Treatment goal | The 2026 guideline, set by risk category | One person, with their clinician | No — written for a situation |

Why a reference range is not a target
🔬 How It Works: A reference range is built by testing large groups of healthy people and describing where most results fall. It is a picture of a population, not a statement about what is good for you. MedlinePlus puts it plainly: because these ranges vary, the word normal can be misleading.
Why cholesterol behaves differently from your other results
This next part is our reading of two federal pages, not a statement either makes alone. MedlinePlus says it cannot publish reference ranges for most tests, because ranges depend on each lab’s method — yet it publishes cholesterol tables anyway. Read together, those statements mean the levels everyone quotes are not reference ranges at all; they are risk thresholds set by guideline, which is why they can be printed for everyone.
Why your report’s range does not match the chart
Because your lab and the chart answer different questions. Labs often use different testing methods, so they use different reference ranges — which is why MedlinePlus advises checking the range printed on your own report rather than one found elsewhere, including the table above.
Different labs, different ranges
🔬 How It Works: Two labs can test the same blood and report the same result against different ranges, because each range was built from that lab’s own method and sample. Results from two labs therefore cannot be compared directly, and tracking a trend works best when the same lab tests each time.
The principle governs every panel you have had — what a normal range means on a basic metabolic panel walks through it on different values. Sample conditions matter too: whether you had eaten before the draw moves one of these numbers most.
An H beside a value is not a diagnosis
A result outside the range may or may not signal a problem, and healthy people commonly have results outside it. A result inside it is no guarantee either. MedlinePlus also states that ideal cholesterol values depend on your own risk factors — including existing heart disease or diabetes — so a flag is a prompt for a conversation, not a finding.
The two values that do not behave like the others
Three of the five follow one logic: lower is better, and one published level covers adults. HDL and triglycerides do not.
HDL: the value where high is the good direction
HDL cholesterol is the number you want high. MedlinePlus states that levels above 60 mg/dL are desired, and its results table adds that for men aged 20 and older, under 40 mg/dL is listed as low — while publishing no HDL row for women. For a low-end cut-off, read the range on your own report and ask your clinician which they use.
Triglycerides: a separate page and a separate scale
Triglycerides are graded in four bands, not against one level. MedlinePlus calls these the commonly used guidelines for adults:
- Healthy: less than 150 mg/dL
- Borderline high: 150 to 199 mg/dL
- High: 200 to 499 mg/dL
- Very high: 500 mg/dL and higher
Guidelines for children and teenagers differ, and levels that are too low are very uncommon. It is also read alongside others — why triglycerides are looked at with the rest of your panel covers that.
⚠️ Clinical Warning: MedlinePlus states that very high triglyceride levels increase the risk of sudden pancreatitis. A result in that band is not one to read off a chart or leave until a routine appointment — contact the clinician who ordered the test and ask how soon they want to see you.
✅ Patient Action: If your triglycerides are 500 mg/dL or above, ask your primary care physician: “Given this triglyceride level, do you want to repeat the test fasting, and does it change how you read the rest of my panel?”
Some reports carry a sixth line; MedlinePlus gives a normal VLDL as under 30 mg/dL. A very high triglyceride result can also stop the lab producing an LDL number at all — why some reports show no LDL line explains that.
Your goal is a different number from normal
Since March 2026 a third kind of number has circulated — the one most likely to be quoted at you in an appointment.
What changed in the 2026 guideline
The 2026 dyslipidemia guideline replaced the 2018 blood cholesterol guideline and restored explicit LDL and non-HDL treatment goals, after years in which guidance emphasised percentage reductions. Goals are set by risk category, not by one population level — which is why a goal and a desirable level are now visibly different numbers.
Why two people with the same LDL get different answers
For people who have already had a cardiovascular event and are assessed as very high risk, the guideline sets a goal of LDL below 55 mg/dL and non-HDL below 85 mg/dL. For the smaller group with established disease not at very high risk, it is LDL below 70 and non-HDL below 100 mg/dL. Neither is the published adult level of 100 mg/dL, and neither is wrong — a desirable level and a treatment goal answer different questions.
📊 Clinical Data Point: Approximately 25% of adults have an LDL cholesterol above 130 mg/dL — Source: the 2026 guideline summary on dyslipidemia management, NIH Bookshelf, updated May 2026.
What this means if you are already being treated
MedlinePlus notes that an LDL of 190 mg/dL or higher is always considered too high, and that levels from 70 to 189 mg/dL are most often considered too high for people in specific situations — including those with diabetes aged 40 to 75, and those with a history of heart disease or stroke. Which situation applies decides whether a number is at goal, and no chart can make that call.
✅ Patient Action: Ask your primary care physician or cardiologist: “Given my risk factors, is there a number you want my LDL and non-HDL under, or are we watching the trend instead?”
What to check on your own report first
Three checks turn a page of numbers into something usable, and none requires deciding anything.
The three things worth writing down
- The range printed beside each result — your lab’s range, and the one your result was flagged against.
- Whether the LDL line says calculated — an estimated value and a measured one are not read the same way.
- Which lab ran the test — comparing a trend works best when the same lab does the testing each time.
The one question to bring to the appointment
Ask the clinician who ordered the test: “Which of these five numbers are you actually watching for me, and what would make you want to recheck?” That resolves the confusion in your own case, which is the only case that matters to you.
If a value came back outside its range, what to do about a high cholesterol result picks up there.
Common questions about normal lipid panel results
1. Why do different sources give different cholesterol numbers?
Because they answer different questions — a lab reports a reference range, health authorities publish desirable levels, and the 2026 guideline sets goals by risk category. None of the three is wrong; they simply describe different things. Why sources count and report the panel differently covers the same problem one level up.
2. Is my LDL goal the same as the normal LDL level?
Not necessarily. The published level for adults 20 and older is an LDL below 100 mg/dL, while the 2026 guideline sets a goal below 55 mg/dL for people who have already had a cardiovascular event and are at very high risk. Which one applies depends on your risk category, so ask your clinician which number they are using for you.
3. Does one out-of-range value mean something is wrong?
Not on its own. MedlinePlus states that a result outside the reference range may or may not indicate a health problem, and that healthy people commonly have results outside it. A result inside the range is not a guarantee of good health either, which is why a flagged value is a reason to ask a question rather than a finding.
The short version
Your lab’s range describes a population. The published level describes a risk threshold. A treatment goal describes one person’s situation — and only the third was written with anyone in particular in mind.
Bring the report, ask which of the five they are watching for you, and let the chart go.
