Lipid Panel Reference Tool
Enter your lipid panel results to see where each component — Total Cholesterol, LDL, HDL, Triglycerides, and Non-HDL — sits versus general reference ranges. This is a wellness reference, not a diagnostic tool.
Reference bands shown reflect commonly cited NCEP ATP III educational ranges and may vary across laboratories. This tool shows each lipid component against its own reference range only and does not calculate cardiovascular risk. Always discuss your lipid panel results with a qualified healthcare provider.
How to Read a Lipid Panel
A standard lipid panel reports four numbers — Total Cholesterol, HDL, LDL, and Triglycerides — plus typically a calculated Non-HDL. Each one describes something different about lipid biology. Educational reference bands published by NCEP ATP III in 2001 are still broadly used to frame what a result means in general terms, while subsequent guidelines such as the ACC/AHA 2018 cholesterol guideline and the ESC/EAS 2019 European dyslipidaemia guidelines describe how clinicians may approach lipid management in different contexts. This tool shows each component against its own reference range; it does not calculate risk and is not a substitute for clinical evaluation.

Why Different Components Are Discussed
Educational literature describes how the focus among lipid components varies depending on someone's broader health context. These are general descriptions; how they apply to any individual is a conversation for a qualified healthcare provider.
- General context: LDL and non-HDL are commonly highlighted in lifestyle and educational discussions of lipid biology.
- Metabolic context: In metabolic syndrome, pre-diabetes, or type 2 diabetes, references describe triglycerides, the TG/HDL ratio, non-HDL, and apoB as informative because LDL particles can become small and dense. apoB counts the number of particles other than HDL rather than the cholesterol mass within them.
- Very elevated LDL (above 190 mg/dL / 4.9 mmol/L): Educational references discuss familial hypercholesterolaemia as a possibility worth investigating with a clinician. Values in this range warrant follow-up with your healthcare provider.
- Very elevated triglycerides (above 500 mg/dL / 5.6 mmol/L): Values in this range warrant follow-up with your healthcare provider. Discussion of management belongs with a clinician.
- People with a cardiovascular history: Educational references describe lower LDL ranges discussed by clinicians for people with prior cardiovascular events. Whether and how this applies to any individual is a clinical conversation, not a calculator output.
Beyond the Basic Panel
Educational literature describes several additional measurements that clinicians sometimes discuss alongside the standard four numbers:
- Apolipoprotein B (apoB) — counts non-HDL lipoprotein particles directly. Often discussed in metabolic syndrome, diabetes, and mixed dyslipidaemia where LDL cholesterol and LDL particle number can diverge.
- Lipoprotein(a), or Lp(a) — a genetically determined LDL-like particle. Educational references describe it as informative in selected contexts and typically measured once in a lifetime.
- High-sensitivity CRP (hs-CRP) — a marker of low-grade inflammation discussed in educational cardiology references; the JUPITER trial is often cited in this context.
- Lipoprotein subfractions (LDL particle number, size) — research-oriented measurements that are sometimes discussed in specific contexts.
- Coronary artery calcium (CAC) score — a CT-based imaging test discussed in educational references about atherosclerotic burden, ordered and interpreted by clinicians.
Whether any of these are appropriate for an individual is a clinical decision. This tool does not order, interpret, or recommend additional testing.
Fasting vs Non-Fasting
Both the 2016 EAS/EFLM consensus and the 2019 ESC/EAS guidelines describe non-fasting lipid panels as suitable for most routine assessment. HDL, Total, and Non-HDL change minimally after a meal; triglycerides rise modestly. Fasting may still be requested when the specific focus is triglyceride evaluation, when using Friedewald's LDL calculation, or when following an established monitoring protocol. Always follow your lab's specific instructions and discuss any questions with your healthcare provider.
What This Tool Doesn't Do
This tool shows where each component sits versus a general reference range. It does not calculate any risk score, does not assess cardiovascular risk, and does not recommend any treatment. This tool does not calculate risk; that requires the Pooled Cohort Equation or similar tool plus a clinician. For any questions about what your lipid panel means in your context, please speak with a qualified healthcare provider.
