Fructosamine
Fructosamine measures glycated serum proteins, mostly albumin, and reflects average blood glucose over the prior two to three weeks. It is useful when HbA1c is unreliable, such as in hemoglobinopathies, hemolysis, or recent transfusion, and for tracking rapid changes in glucose control during pregnancy or medication adjustments.
Optimal range: who says what
No institution or named practitioner we track states an optimal target for Fructosamine. How we verify ranges.
- No stated targetNo separate optimal establishedReflects average glucose over 2-3 weeks; useful when HbA1c is unreliable
- Lab reference interval200-285 μmol/LWhat a lab report flags against. A lab interval is not an optimal target.

Why Fructosamine matters
Reflects shorter-term glucose control than HbA1c. Useful when HbA1c is unreliable (hemoglobin variants, anemia). Helps detect rapid changes in glucose control.
