Iron: units, conversion and tracking
Updated
Short answer
Iron is reported in µg/dL and µmol/L. 1 µmol/L = 5.585 µg/dL.

What is iron?
The amount of iron circulating in the blood, which changes through the day.
BiomarkerHQ groups iron under Vitamins and minerals. On lab reports it can also appear as iron total, serum iron, iron serum and fe.
Iron units and conversion
BiomarkerHQ stores each iron result in the unit printed on the report, and charts and compares results in µg/dL.
1 µmol/L = 5.585 µg/dL
1 µg/dL = 0.1791 µmol/L
| µmol/L | µg/dL |
|---|---|
| 5 µmol/L | 27.92 µg/dL |
| 10 µmol/L | 55.84 µg/dL |
| 15 µmol/L | 83.77 µg/dL |
| 20 µmol/L | 111.7 µg/dL |
| 25 µmol/L | 139.6 µg/dL |
| 30 µmol/L | 167.5 µg/dL |
| 35 µmol/L | 195.5 µg/dL |
| µg/dL | µmol/L |
|---|---|
| 30 µg/dL | 5.372 µmol/L |
| 60 µg/dL | 10.74 µmol/L |
| 90 µg/dL | 16.12 µmol/L |
| 120 µg/dL | 21.49 µmol/L |
| 150 µg/dL | 26.86 µmol/L |
| 180 µg/dL | 32.23 µmol/L |
| 200 µg/dL | 35.81 µmol/L |
For another value, use the lab unit converter. It converts units only and does not interpret a result.
Tracking iron over time
In BiomarkerHQ, each iron 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 iron in?
Iron is reported in µg/dL and µmol/L. BiomarkerHQ stores each result in the unit printed on the report and uses µg/dL for charts and comparisons.
How do I convert iron from µmol/L to µg/dL?
1 µmol/L = 5.585 µg/dL. For example, 20 µmol/L is 111.7 µg/dL.
How do I convert iron from µg/dL to µmol/L?
1 µg/dL = 0.1791 µmol/L. For example, 120 µg/dL is 21.49 µmol/L.
Does BiomarkerHQ interpret my iron 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.
