High Fructosamine: what it means
A Fructosamine result above the normal range is considered high. Here is what a raised Fructosamine can point to, and when it is worth discussing with a doctor.
Reference range: ~200–285 umol/L; reflects average glucose over the past 2–3 weeks — a shorter window than HbA1c, useful when HbA1c is unreliable
Understand your full resultWhat a high Fructosamine can mean
- Higher average blood sugar over the past 2–3 weeks — poorer diabetes control, or newly high glucose.
- Useful where HbA1c is unreliable — haemoglobin disorders, recent blood loss/transfusion, altered red-cell lifespan.
- A rise after a treatment change — shows worsening control sooner than HbA1c would.
When to discuss with a doctor
Fructosamine is a second-line glucose test, not a routine one. It is worth using when HbA1c cannot be trusted — for example with a haemoglobin variant, after recent bleeding or a transfusion, or when red-cell turnover is abnormal — because it gives an average glucose without relying on red cells. It is also useful to judge the effect of a diabetes treatment change over a few weeks rather than waiting three months for HbA1c. Its result must be interpreted with albumin, since a low albumin can falsely lower it. Mediora.AI shows fructosamine alongside HbA1c and glucose so the glucose picture is read with the right test; the diabetes management decision belongs with your doctor.
