A lipid panel is a set of results, not a diagnosis from one number. Read total cholesterol, LDL, HDL and triglycerides together, then place them in the contextof cardiovascular risk. In Korea’s national screening program, lipid tests may be included at particular ages and intervals; confirm what your own report actually contains.
Four values on the report
| Term | What it measures | What to check |
|---|---|---|
| Total cholesterol (TC) | Total cholesterol in blood | It does not show the LDL and HDL components by itself. |
| LDL-C | Low-density lipoprotein cholesterol | Check whether it was calculated or measured directly. |
| HDL-C | High-density lipoprotein cholesterol | Consider it alongside other risks, rather than alone. |
| Triglycerides (TG) | Another type of fat in blood | Note food, alcohol and any preparation instructions. |
How to read the numbers
- Check the unit, often mg/dL, and compare the same test and unit with any prior report.
- If LDL is marked as calculated, ask which method the laboratory used and whether the triglyceride result affects that estimate. A direct LDL result is a different measurement.
- Consider age, smoking, blood pressure, diabetes, kidney disease, family history, established cardiovascular disease and medicines. An individual management goal depends on overall risk.
- A general reference range is not an instruction to start or stop medication. Ask your clinician what follow-up is appropriate for you.
What if I did not fast?
Whether another test is needed depends on the purpose of testing and the results, including triglycerides. Note whether you followed the provider’s instructions and ask about repeat testing if the conditions are unclear. This guide does not set an individual testing interval.
Questions for a visit
- Was my LDL calculated or measured directly?
- Is the change from my previous report meaningful, and were the units and preparation comparable?
- What goal and next check make sense given my other risk factors?
Use the LDL and non-HDL cholesterol calculator to select units, review methods and limits, and prepare a printable summary with an optional blank lipid log.
Use the blood pressure and lab log for dates and conditions, or return to the lab results guide.
