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

What is TIBC?
Total iron-binding capacity measures how much iron the blood protein transferrin can carry.
BiomarkerHQ groups TIBC under Vitamins and minerals. On lab reports it can also appear as total iron binding capacity, iron binding capacity and iron binding capacity total.
TIBC units and conversion
BiomarkerHQ stores each TIBC 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 |
|---|---|
| 30 µmol/L | 167.5 µg/dL |
| 40 µmol/L | 223.4 µg/dL |
| 50 µmol/L | 279.2 µg/dL |
| 60 µmol/L | 335.1 µg/dL |
| 70 µmol/L | 390.9 µg/dL |
| 80 µmol/L | 446.8 µg/dL |
| 90 µmol/L | 502.6 µg/dL |
| µg/dL | µmol/L |
|---|---|
| 250 µg/dL | 44.77 µmol/L |
| 300 µg/dL | 53.72 µmol/L |
| 350 µg/dL | 62.67 µmol/L |
| 400 µg/dL | 71.63 µmol/L |
| 450 µg/dL | 80.58 µmol/L |
| 500 µg/dL | 89.53 µmol/L |
| 550 µg/dL | 98.49 µmol/L |

Tracking TIBC over time
In BiomarkerHQ, each TIBC 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 TIBC in?
TIBC 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 TIBC from µmol/L to µg/dL?
1 µmol/L = 5.585 µg/dL. For example, 60 µmol/L is 335.1 µg/dL.
How do I convert TIBC from µg/dL to µmol/L?
1 µg/dL = 0.1791 µmol/L. For example, 400 µg/dL is 71.63 µmol/L.
Does BiomarkerHQ interpret my TIBC 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.
