VLDL Cholesterol
The cholesterol carried in VLDL particles, which move triglycerides through your blood. Most labs estimate it by dividing triglycerides by 5.

What it is
VLDL (very low-density lipoprotein) particles are made by the liver to carry triglycerides, plus some cholesterol, to your tissues. As they drop off their triglycerides they shrink into leftover (remnant) particles and eventually become LDL. Most labs do not measure VLDL cholesterol directly. They estimate it as triglycerides divided by 5 (in mg/dL), so the number moves in step with your triglycerides and adds no new information. Some labs use a different divisor or measure it directly with special methods.
Why it matters
VLDL cholesterol is one part of non-HDL cholesterol, the cholesterol in all the particles that can build up in artery walls. The NCEP ATP III guideline called VLDL cholesterol the most readily available measure of leftover (remnant) fat particles, and, for people with high triglycerides, set non-HDL goals 30 mg/dL above LDL goals on the premise that a VLDL cholesterol up to 30 mg/dL is normal. In everyday practice the estimate mostly serves as a step in calculating LDL cholesterol, so clinicians usually follow triglycerides, LDL or non-HDL cholesterol instead.
If it’s high
A higher VLDL cholesterol (above about 30 mg/dL) mostly reflects higher triglycerides, since the number is calculated from them. A recent meal is a common and harmless reason. Because the estimate gets less accurate as triglycerides climb, a very high number may not be exact. Your clinician can put it in context with your other lipid results.
Common causes
- Eating shortly before the blood draw
- Extra body weight or low physical activity
- Prediabetes or diabetes
- Regular alcohol intake
- Some medicines that raise triglycerides
- Inherited lipid conditions
What can help
- Ask your clinician whether your triglycerides, LDL or non-HDL cholesterol is the better number to follow
- Ask whether to fast before your next lipid panel
- Ask about lifestyle steps linked to lower triglycerides, such as regular physical activity, less alcohol and sugary drinks, and a healthy weight
Usual ranges
What labs print as the reference range, by who was tested. Ranges differ a little between labs, so the range on your own report is the one your result is judged against.

What can affect your result
- Eating before the test: triglycerides rise after meals, and the estimate rises with them
- How your lab gets the number: triglycerides divided by 5, a different divisor, or direct measurement
- Triglycerides above 400 mg/dL, where the estimate is unreliable
- Alcohol, body weight and blood sugar
- Medicines that change triglycerides
- The usual estimate is triglycerides divided by 5, so anything that changes triglycerides changes it. Eating before the test raises triglycerides, and on average random non-fasting triglycerides run about 20% to 25% higher than fasting values.
- The estimate becomes unreliable as triglycerides rise and should not be used above 400 mg/dL.
- In people with a rare inherited condition called familial dysbetalipoproteinemia, VLDL carries more cholesterol than the estimate assumes, so the estimate runs low.
- Some labs use newer equations with a variable divisor instead of 5, or measure VLDL cholesterol directly, so values can differ between labs.
It follows your triglycerides, which can shift within days to weeks after changes in diet, alcohol, weight or medicines.
When to talk to a clinician
VLDL cholesterol itself rarely needs action, but the triglycerides behind it can. If your triglycerides are 500 mg/dL or higher, talk with your clinician soon, because very high triglycerides can lead to inflammation of the pancreas (acute pancreatitis). Call 911 or your local emergency number for severe belly pain, especially with nausea or vomiting.
Questions you could ask
- Does my lab estimate VLDL cholesterol or measure it directly?
- Is my VLDL high only because my triglycerides are high?
- Should I fast before my next lipid panel?
- Which number do you use to track my heart risk: LDL, non-HDL cholesterol, triglycerides or apoB?
Questions people ask
Why is my VLDL cholesterol always my triglycerides divided by 5?
Most labs do not measure VLDL cholesterol. They estimate it by dividing triglycerides (in mg/dL) by 5, so the two numbers always move together. For example, triglycerides of 150 mg/dL give a VLDL cholesterol of 30 mg/dL.
Is VLDL cholesterol the same as LDL cholesterol?
No. VLDL particles carry mostly triglycerides, and they shrink into LDL particles as they deliver their fat. Both are counted in non-HDL cholesterol. Clinicians usually follow LDL, non-HDL cholesterol or triglycerides rather than VLDL.
Why is my VLDL missing or marked as not calculated?
The triglycerides-divided-by-5 estimate is not reliable when triglycerides are above 400 mg/dL, so many labs leave it out, along with the calculated LDL. Your clinician may order a direct LDL test or repeat the panel after fasting.

Is a change real?
VLDL-C naturally varies about 27.6% from test to test in the same healthy person. Between two results from the same lab, a rise of 132% or more, or a fall of 57% or more, is unlikely to be day-to-day noise or lab variation (95% reference change value).

For clinicians and researchers
VLDL-C is conventionally estimated by the Friedewald approach as triglycerides divided by 5 (mg/dL), based on an approximate 5:1 ratio of triglyceride to cholesterol in VLDL; in SI units the divisor is 2.2 (mmol/L). The estimate becomes increasingly unreliable as triglycerides rise, which is why Friedewald LDL-C is not reported above 400 mg/dL. In familial dysbetalipoproteinemia, VLDL is cholesterol-enriched, so TG/5 underestimates it. The Martin-Hopkins method replaces the fixed 5 with an adjustable factor, which improves VLDL-C and LDL-C accuracy. VLDL-C can also be measured directly by ultracentrifugation, electrophoresis or VAP, which gives the same marker by a different method. NCEP ATP III (2001) took VLDL cholesterol of 30 mg/dL or less as normal, calling it the most readily available measure of atherogenic remnant lipoproteins and using it to set non-HDL goals 30 mg/dL above LDL goals. Remnant cholesterol (non-HDL-C minus LDL-C) includes VLDL-C plus IDL-C and, in non-fasting samples, chylomicron remnants. Because the usual VLDL-C is a fixed transform of triglycerides, it adds no independent information beyond the triglyceride result.
