- Standard unit
- pmol/L

- pmol/L, µIU/mL, mIU/L
What does high insulin mean?
Higher values may suggest increased insulin demand or resistance patterns. What counts as high depends on the reference range printed on your lab report, because ranges differ between laboratories.
What does low insulin mean?
Lower values may suggest lower insulin production in context. What counts as low depends on the reference range printed on your lab report, because ranges differ between laboratories.
Insulin units and conversion
Mediki shows insulin in pmol/L. Labs may report it in other units; Mediki converts them automatically so results from different labs line up on one chart.
| Unit on your report | Convert to pmol/L | Convert back |
|---|---|---|
| µIU/mL, mIU/L | 1 µIU/mL = 6.944 pmol/L | 1 pmol/L = 0.144 µIU/mL |
Convert a value from your report with the blood test unit converter.
Why track insulin over time?
A single insulin result is a snapshot. Comparing it with your earlier tests shows whether a value is stable, slowly drifting, or responding to a change in treatment or lifestyle, which is often more useful than one number on its own.
