About this biomarker
Insulin is made by the pancreas and helps regulate blood sugar. Blood insulin testing is often used alongside glucose-related markers.
Why it matters
It can help show how strongly the body is responding to blood sugar and may add context to metabolic patterns.
What lower levels may suggest
Low insulin can be seen when the pancreas is producing less insulin than expected.
What higher levels may suggest
High insulin may be seen when the body is producing more insulin to keep blood sugar controlled.
Common tests
Fasting insulin, insulin with glucose testing, insulin during oral glucose tolerance testing
