Total cholesterol test: normal range explained
Also printed as: Cholesterol Total, Serum Cholesterol, Cholesterol, Total
Total cholesterol is the overall amount of cholesterol in your blood, including the cholesterol carried by LDL and HDL particles. The adult range commonly printed is <200 mg/dL, the level the NHLBI calls desirable and MedlinePlus calls healthy, with 200 to 239 borderline high, but the range printed on your own report is the one that applies.

What is the normal range for total cholesterol?
| Printed for | Range |
|---|---|
| Adults | <200mg/dL |
| In mmol/L | <5mmol/L |
Reference ranges vary between laboratories. Always use the range printed on your own report. Why ranges differ between labs
| Label | Range |
|---|---|
| Desirable | <200 mg/dL |
| Borderline high | 200–239 mg/dL |
| High | ≥240 mg/dL |
These labels are the source's own, not Amara's. Your doctor reads your result with your history and other tests.

What does total cholesterol measure?
A total cholesterol test measures all the cholesterol in your blood. Cholesterol is a waxy, fat-like substance found in every cell; your body needs some of it to make hormones, vitamin D and substances that help digest food, and the liver makes all it needs. The total adds together the cholesterol carried by LDL, HDL and VLDL particles, and it is usually reported as part of a lipid profile with LDL, HDL and triglycerides.

Why do doctors order the total cholesterol test?
Doctors order a cholesterol test to understand the risk of heart disease and stroke, often as part of a routine check-up. MedlinePlus suggests adults aged 20 to 65 are tested every five years, men aged 45 to 65 and women aged 55 to 65 every one to two years, and people over 65 every year, with more frequent tests for people with risk factors. The total is read with LDL, HDL and triglycerides, not alone.

What can change your total cholesterol result?
Several everyday things can move a cholesterol result, besides the genes you were born with.
- A diet high in saturated fat raises blood cholesterol.
- Carrying extra weight and getting little physical activity tend to push total cholesterol up.
- Smoking lowers HDL and raises LDL, which changes the total.
- Cholesterol tends to rise with age, and a woman's risk of high cholesterol rises after the menopause.
- Recent illness, some medicines and having recently had a baby can make the level lower or higher than usual.
- Stress hormones such as corticosteroids can make the body produce more cholesterol, and heavy alcohol use raises the total.
- Genes partly decide how much cholesterol your body makes, so high cholesterol can run in families.

How do you read total cholesterol on your lab report?
Indian reports print total cholesterol in mg/dL; UK-style reports use mmol/L, where the NHS puts the healthy level below 5 mmol/L. Some reports print the NCEP ATP III categories published by the NHLBI as a legend rather than one range: desirable below 200, borderline high 200 to 239 and high 240 or above.
Fasting matters less than it once did: the NHS says eating before the test makes little difference to total, HDL and non-HDL cholesterol, while MedlinePlus says you may be asked to fast for 9 to 12 hours when triglycerides are measured too. Note on each report whether you fasted, and read the value against the range or legend beside it.
Amara reads total cholesterol with the range printed beside it on each report, flags a value outside that range, and shows what changed since your last report. Try it with two sample reports
A sample Amara row for Total Cholesterol: 214 mg/dL on 6 Oct 2025 at Lab A (sample), then 188 mg/dL on 14 May 2026 at Lab B (sample), each with its lab's printed range.

Questions people ask about total cholesterol
Do I need to fast for a lipid profile?
Fasting for a lipid profile depends on the lab and on which values are measured. MedlinePlus says you may need to fast for 9 to 12 hours before a cholesterol test, while the NHS says eating makes little difference to total, HDL and non-HDL cholesterol. Follow the instructions your lab gives you.
Why does my report print three cholesterol ranges?
Three ranges on a cholesterol report are usually the NCEP ATP III categories published by the NHLBI: desirable below 200 mg/dL, borderline high 200 to 239 and high 240 or above. They are a legend, not three separate tests. Read your value against whichever row it falls in, and let your doctor read it with your LDL, HDL and history.
What is a normal total cholesterol level in mmol/L?
The NHS lists a healthy total cholesterol as below 5 mmol/L for healthy adults, and says the target depends on age, health conditions and cardiovascular risk. Reports in mg/dL follow a different scale, where MedlinePlus lists below 200 mg/dL as healthy for adults aged 20 or older. The range printed on your own report applies.
Is total cholesterol more important than LDL?
Total cholesterol is read together with LDL, HDL and triglycerides, because it adds up cholesterol from particles that behave differently. MedlinePlus describes LDL as the main source of artery blockages and a higher HDL as protective, so two people with the same total can carry different risk. Your doctor reads the full profile with your history.
