What is LDL Cholesterol?
The "bad" cholesterol that contributes to plaque in arteries. Lower is generally better.
LDL Cholesterol Reference Range
These are the typical adult reference ranges used by major US labs. Your report will include the specific range used by the lab that processed your sample.
| Population | Range |
|---|---|
| age 18+ | 0.000 – 100 mg/dL |
Reference ranges are educational. Always interpret your result with the specific range printed on your lab report and discuss anything outside the range with a clinician.
What your LDL Cholesterol result may mean
Above 100 mg/dL is considered above optimal; targets vary by individual cardiovascular risk.
Educational only — not a diagnosis. Many factors can influence a single result. Discuss anything that concerns you with a healthcare provider.
