What is HDL cholesterol?
The cholesterol carried by HDL particles.
BiomarkerHQ groups HDL cholesterol under Lipids. On lab reports it can also appear as hdl, hdl-c, hdl chol, high density lipoprotein and high density lipoprotein cholesterol.
HDL cholesterol units and conversion
BiomarkerHQ stores each HDL 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 |
|---|---|
| 0.8 mmol/L | 30.94 mg/dL |
| 1 mmol/L | 38.67 mg/dL |
| 1.2 mmol/L | 46.4 mg/dL |
| 1.4 mmol/L | 54.14 mg/dL |
| 1.6 mmol/L | 61.87 mg/dL |
| 1.8 mmol/L | 69.61 mg/dL |
| 2 mmol/L | 77.34 mg/dL |
| mg/dL | mmol/L |
|---|---|
| 30 mg/dL | 0.7758 mmol/L |
| 40 mg/dL | 1.034 mmol/L |
| 50 mg/dL | 1.293 mmol/L |
| 60 mg/dL | 1.552 mmol/L |
| 70 mg/dL | 1.81 mmol/L |
| 80 mg/dL | 2.069 mmol/L |
| 90 mg/dL | 2.327 mmol/L |

Tracking HDL cholesterol over time
In BiomarkerHQ, each HDL 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 HDL cholesterol in?
HDL 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 HDL cholesterol from mmol/L to mg/dL?
1 mmol/L = 38.67 mg/dL. For example, 1.4 mmol/L is 54.14 mg/dL.
How do I convert HDL cholesterol from mg/dL to mmol/L?
1 mg/dL = 0.02586 mmol/L. For example, 60 mg/dL is 1.552 mmol/L.
