Can this result diagnose a condition on its own?

No. Laboratory results are interpreted with symptoms, medical history, sampling conditions, and related tests.

Which reference range or cutoff should I use?

Start with the performing laboratory's report and the purpose of testing; diagnostic cutoffs are separate sourced clinical thresholds.

When should I discuss the result with a healthcare professional?

Results that are clearly outside range, persistent, symptomatic, or unexpected should be reviewed by a healthcare professional.

Information about a laboratory test

High Non-HDL Cholesterol: What Does It Mean?

High non-HDL can indicate a greater combined burden of LDL and other atherogenic particles.

Test summary

Test name: Non-HDL Cholesterol
Abbreviations: Non-HDL-C, non-HDL
Category: Cardiometabolic / Lipids
Panel: Lipid Panel / Calculated Lipids
Specimen: Calculated from lipid panel
Common units: mg/dL, mmol/L

What does the test measure?

Calculated as total cholesterol minus HDL cholesterol and reflects cholesterol carried by atherogenic lipoproteins as a group.

Why is the test ordered?

Can complement LDL for risk assessment, particularly when triglycerides are high or cardiometabolic risk is increased.

Information about a low result

Lower non-HDL is generally favorable in risk contexts; clinical goals depend on the person's risk level.

Information about a high result

High non-HDL can indicate a greater combined burden of LDL and other atherogenic particles.

Reference and clinical context

Use the laboratory report as context, but treatment goals and risk thresholds vary with age, cardiovascular risk, diabetes, kidney disease, and current therapy.

Reference context 1

< 130 mg/dL

Population: Adults
Age range: 20
Specimen: Calculated

Healthy adult level

The source uses <130 mg/dL as the threshold for this context. Individual risk and laboratory context still matter.

Reference context 2

< 120 mg/dL

Population: Children / adolescents
Age range: 0 – 19
Specimen: Calculated

Acceptable pediatric level

This <120 mg/dL threshold is pediatric and should be applied with the stated age range and clinical context.

Reference ranges may vary by laboratory, method used, age, sex, pregnancy status, and clinical context. The reference range on your own laboratory report takes precedence.

Interpretation notes

It is a calculated marker and targets vary by cardiovascular risk. ApoB can provide complementary particle information.
