Years

before glucose rises, insulin can signal metabolic issues

Source: Diabetes Care 2021

Why This Test

Fasting insulin can detect metabolic dysfunction years before glucose changes. Your body can maintain normal blood sugar by producing more insulin—masking developing insulin resistance. By the time glucose rises, you may have been insulin resistant for years.

Common Questions
