Non-HDL cholesterol is a calculated value, total cholesterol minus HDL cholesterol, not a separate substance measured in blood. It captures cholesterol in all atherogenic particles, so practitioners use it as one atherogenic load figure that stays valid when triglycerides are high or the client has not fasted. Lab flags differ, and treatment targets depend on absolute risk, so read it with other risk factors.
| Test type | Calculated value |
|---|---|
| Measurements required | Total cholesterol and HDL cholesterol |
| Sample and collection | Blood draw at a collection centre |
| Preparation | Non-HDL cholesterol is accurate without fasting, so you can eat as usual if this is your only test. |
| Turnaround | 3 to 5 business days |
| Available through | Lipid Studies, part of the Baseline Health Check. Also in: Full Body Health Check, Weight Management Test. |
| Pricing | Included in the $99 Baseline Health Check |
| Results | Returned in the Vively practitioner platform, beside your client's other markers |
What are the Non-HDL Cholesterol reference and optimal ranges?
| Typical lab reference | Vively optimal | |
|---|---|---|
| Adults | Below 3.4 mmol/L | Below 3.0 mmol/L |
Labs differ, and many Australian labs use a higher flag of about 4.0 mmol/L, so read the result against the range on the client's report (RCPA). The optimal cut-off is a long-term health target; treatment targets depend on absolute risk and are set by the client's doctor.
Calculate non-HDL cholesterol
Enter both values from the same lipid panel. The result is worked out in your browser. Nothing you enter is stored or sent.
Formula. Non-HDL cholesterol = total cholesterol (mmol/L) − HDL cholesterol (mmol/L)
Most labs already print non-HDL cholesterol on the lipid report. Use this to check it or to work it out when it is missing.
Limits. Treatment targets depend on absolute cardiovascular risk, so read the result with the client's other risk factors.
A guide only, not a diagnosis. One result is a starting point: read it with symptoms, history and a repeat test, and check it against the range on your client's report.
How do you arrange Non-HDL Cholesterol testing through Vively?
- Get verified. Practitioners with a recognised qualification or membership (ATMS, NHAA, ANTA, Dietitians Australia, NSA, CMA or Ahpra registration) can request free practitioner access.
- Choose a panel. Log in to the practitioner platform and pick a panel that includes Non-HDL Cholesterol, or build your own. It is included in the $99 Baseline Health Check.
- Client collects. Your client collects at a partner collection centre, with their request on their phone or printed.
- Review results. Results come back to you in the practitioner platform, beside your client's other markers, ready for the follow-up consult.

Why does the optimal range sit there?
Our optimal cut-off of below 3.0 mmol/L sits under the 3.4 mmol/L lab cut-off to flag rising atherogenic load before it reaches a lab flag.
Non-HDL includes the VLDL and remnant load LDL misses when triglycerides are raised. In a meta-analysis of statin-treated patients, on-treatment non-HDL was more strongly associated with cardiovascular events than LDL or ApoB (Boekholdt and colleagues, JAMA, 2012).
That makes non-HDL the steadiest lipid figure to track between tests.
ApoB counts particles directly, so it is the better tiebreaker where non-HDL and ApoB disagree.
What should Non-HDL Cholesterol be read with?
- ContextNon-HDL raised, LDL in range
Possible excess VLDL and remnant cholesterol, usually with raised triglycerides.
- ContextNon-HDL raised with high fasting insulin or triglyceride to HDL ratio
Often seen with insulin resistance and fatty liver.
- ContextNon-HDL in range, ApoB above range
Possibly more, smaller particles than the cholesterol figure suggests.
- ContextNon-HDL above 3.4 mmol/L with high Lp(a) or a family history
Adds to absolute cardiovascular risk and is worth GP review.
- ContextNon-HDL raised with high TSH
Possible hypothyroidism.
What can affect a Non-HDL Cholesterol result?
- Hypothyroidism, nephrotic syndrome and cholestasis, which raise it.
- Pregnancy and menopause, which raise it.
- Acute illness, surgery or a recent heart attack, which lower it for several weeks.
- Statins, ezetimibe and plant sterols lower it; corticosteroids, retinoids and some antiretrovirals raise it.
- Alcohol and high refined carbohydrate intake, which raise it through VLDL.
When should you refer the client to their GP?
- Non-HDL persistently above 3.4 mmol/L with diabetes, kidney disease, high blood pressure or smoking, for absolute risk assessment.
- LDL 5.0 mmol/L or above, or total cholesterol above 7.5 mmol/L.
- A family history of heart disease before 55 in men or 60 in women.
- Triglycerides above 5.6 mmol/L.

Preparing for your Non-HDL Cholesterol test
- Non-HDL cholesterol is accurate without fasting, so you can eat as usual if this is your only test.
- If your practitioner has requested the Baseline Health Check, fast for 8 to 12 hours before a morning collection (water is fine).
- Take your pathology request to any of 4,000+ collection centres. Bring it printed or on your phone.
- Keep taking prescribed medicines as usual unless your doctor tells you otherwise.
- Results usually take 3 to 5 business days and come to your practitioner. Book your results appointment for after that.
How do practitioners use Non-HDL Cholesterol with clients?
Non-HDL is a good single number to track with clients because it moves with both LDL and triglyceride-rich particles. A Mediterranean-style diet, regular activity, weight management and stress reduction can lower it; a persistently high result in a client with other risk factors needs the GP.
Non-HDL Cholesterol FAQs
Can a naturopath, nutritionist or dietitian order non-HDL cholesterol through Vively?
Yes. Add it to a client panel on the Vively practitioner platform. It is part of Lipid Studies in the $99 Baseline Health Check, and is also in Full Body Health Check and Weight Management Test. No account yet? Request free access.
Is non-HDL cholesterol better than LDL?
Often, yes. Non-HDL includes the cholesterol in VLDL and remnant particles that LDL leaves out, so it gives a truer picture when triglycerides are high or the sample is non-fasting, and it needs no equation. LDL is still the figure most treatment targets use, so report both when you refer a client to their GP.
Should I order ApoB if I already have non-HDL?
Consider it when non-HDL and LDL disagree, triglycerides are raised or there is a strong family history. Non-HDL estimates atherogenic cholesterol, and ApoB counts atherogenic particles, one ApoB per particle. The two usually agree; when they do not, ApoB is the better guide to particle number and risk.
How do I calculate non-HDL cholesterol from a lipid report?
Subtract HDL from total cholesterol, both in mmol/L. A total of 5.2 mmol/L with HDL of 1.4 mmol/L gives a non-HDL of 3.8 mmol/L, above the reference below 3.4 mmol/L. No fasting or equation is needed, so you can calculate it from any standard lipid profile.
What besides saturated fat can raise non-HDL cholesterol?
Alcohol and high refined carbohydrate intake raise it through VLDL. Hypothyroidism, nephrotic syndrome, cholestasis, pregnancy, menopause, corticosteroids and retinoids also raise it. If non-HDL is high with normal LDL, think VLDL and remnants first, and check triglycerides, TSH and fasting insulin before changing the dietary approach.
