IGF-1: units, conversion and tracking
Updated
Short answer
IGF-1 is reported in ng/mL and nmol/L. 1 nmol/L = 7.649 ng/mL.

What is IGF-1?
Insulin-like growth factor 1 is a hormone made mainly by the liver in response to growth hormone.
BiomarkerHQ groups IGF-1 under Hormones. On lab reports it can also appear as igf1, igf-i, insulin like growth factor 1, insulin like growth factor i and somatomedin c.
IGF-1 units and conversion
BiomarkerHQ stores each IGF-1 result in the unit printed on the report, and charts and compares results in ng/mL.
1 nmol/L = 7.649 ng/mL
1 ng/mL = 0.1307 nmol/L
| nmol/L | ng/mL |
|---|---|
| 5 nmol/L | 38.24 ng/mL |
| 10 nmol/L | 76.49 ng/mL |
| 15 nmol/L | 114.7 ng/mL |
| 20 nmol/L | 153 ng/mL |
| 25 nmol/L | 191.2 ng/mL |
| 30 nmol/L | 229.5 ng/mL |
| 35 nmol/L | 267.7 ng/mL |
| ng/mL | nmol/L |
|---|---|
| 50 ng/mL | 6.537 nmol/L |
| 100 ng/mL | 13.07 nmol/L |
| 150 ng/mL | 19.61 nmol/L |
| 200 ng/mL | 26.15 nmol/L |
| 250 ng/mL | 32.68 nmol/L |
| 300 ng/mL | 39.22 nmol/L |
| 400 ng/mL | 52.29 nmol/L |
For another value, use the lab unit converter. It converts units only and does not interpret a result.
Tracking IGF-1 over time
In BiomarkerHQ, each IGF-1 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 IGF-1 in?
IGF-1 is reported in ng/mL and nmol/L. BiomarkerHQ stores each result in the unit printed on the report and uses ng/mL for charts and comparisons.
How do I convert IGF-1 from nmol/L to ng/mL?
1 nmol/L = 7.649 ng/mL. For example, 20 nmol/L is 153 ng/mL.
How do I convert IGF-1 from ng/mL to nmol/L?
1 ng/mL = 0.1307 nmol/L. For example, 200 ng/mL is 26.15 nmol/L.
Does BiomarkerHQ interpret my IGF-1 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.
