What Insulin measures
Insulin is the hormone that moves glucose into cells. Fasting insulin is often read together with fasting glucose.
If your Insulin is low
Low fasting insulin is typical after a fast and rarely a concern on its own.
Commonly associated with
- Prolonged fasting
- Reduced insulin production
If your Insulin is high
Fasting insulin above the range is commonly associated with insulin resistance, meaning the body needs more insulin to keep glucose typical; a recent meal also raises it.
Commonly associated with
- Non-fasting draw
- Insulin resistance
- Higher body weight
- Polycystic ovary syndrome
Typical reference range
| Group | Typical range |
|---|---|
| Adults | 2.6 – 24.9 uIU/mL |
Typical adult values used by many US labs. Your own report prints the range your lab validated for its method, and that range is the one that counts. Labwise always uses the printed range first.
If it is within range
Your fasting insulin is within the range printed by your lab.
