Fasting Insulin

Insulin measured after an 8-hour fast — a sensitive early marker of insulin resistance.

Definition

Fasting insulin reveals compensatory hypersecretion by the pancreas in the face of insulin resistance — a signal that can show up years before fasting glucose or HbA1c rise. Values under 6 µIU/mL are generally healthy; above 10 suggests insulin resistance.

Reference Range: Values under 6 µIU/mL are generally healthy; above 10 suggests insulin resistance.
