What is LDL cholesterol?
The cholesterol carried by LDL particles, either measured directly or calculated from other lipid results.
BiomarkerHQ groups LDL cholesterol under Lipids. On lab reports it can also appear as ldl, ldl-c, ldl chol, low density lipoprotein and low density lipoprotein cholesterol.
LDL cholesterol units and conversion
BiomarkerHQ stores each LDL cholesterol result in the unit printed on the report, and charts and compares results in mg/dL.
1 mmol/L = 38.67 mg/dL
1 mg/dL = 0.02586 mmol/L
| mmol/L | mg/dL |
|---|---|
| 1 mmol/L | 38.67 mg/dL |
| 2 mmol/L | 77.34 mg/dL |
| 3 mmol/L | 116 mg/dL |
| 4 mmol/L | 154.7 mg/dL |
| 5 mmol/L | 193.4 mg/dL |
| 6 mmol/L | 232 mg/dL |
| 7 mmol/L | 270.7 mg/dL |
| mg/dL | mmol/L |
|---|---|
| 50 mg/dL | 1.293 mmol/L |
| 75 mg/dL | 1.939 mmol/L |
| 100 mg/dL | 2.586 mmol/L |
| 125 mg/dL | 3.232 mmol/L |
| 150 mg/dL | 3.879 mmol/L |
| 175 mg/dL | 4.525 mmol/L |
| 200 mg/dL | 5.172 mmol/L |

Before comparing LDL cholesterol results
Tracking LDL cholesterol over time
In BiomarkerHQ, each LDL cholesterol result is saved with its collection date, its unit and the reference range printed on that report. The timeline charts the results across your draws against the range from each of your own reports, and any two draws can be compared side by side.
- Keep the unit printed on each report. Convert only to compare.
- Keep each report's own range with its result. See why ranges differ between labs.
- Compare the same lab and conditions where you can. See how to compare two blood tests.
Frequently asked questions
Which units do labs report LDL cholesterol in?
LDL cholesterol is reported in mg/dL and mmol/L. BiomarkerHQ stores each result in the unit printed on the report and uses mg/dL for charts and comparisons.
How do I convert LDL cholesterol from mmol/L to mg/dL?
1 mmol/L = 38.67 mg/dL. For example, 4 mmol/L is 154.7 mg/dL.
How do I convert LDL cholesterol from mg/dL to mmol/L?
1 mg/dL = 0.02586 mmol/L. For example, 125 mg/dL is 3.232 mmol/L.
What should I check before comparing LDL cholesterol results?
Calculated and directly measured LDL can differ; the converter only changes units.
Does BiomarkerHQ interpret my LDL cholesterol result?
No. It compares a result only with the reference range printed on your own lab report, as below, within or above, and does not say what the result means. Talk to a qualified clinician about your results.
