Indicator Explainer
LDL Cholesterol
Low-density lipoprotein cholesterol — the primary lipid target in cardiovascular prevention.
This page explains what the indicator is and how results are interpreted in general terms. Reference ranges depend on the laboratory, the method, and your own situation — no single “normal value” applies to everyone. This page is health information, not a diagnosis. For symptoms, treatment, or urgent concerns, contact a healthcare professional.
When it is tested
Measured in cardiovascular risk assessment, before and during lipid-lowering therapy, and in monitoring metabolic and endocrine conditions.
Reading results
Reported values may be calculated or directly measured; calculation assumptions break down when triglycerides are high. Non-fasting sampling is acceptable in many guidelines but shifts values slightly, and acute illness can temporarily lower LDL. Risk interpretation belongs in validated risk frameworks — the number alone is not a diagnosis, and targets differ by overall risk category and guideline.
Questions to ask a professional
- Was this value calculated or directly measured, and were triglycerides normal?
- Was the sample fasting or non-fasting, and which guideline’s target applies?
- How does the value change the overall risk estimate?
