What is a high fructosamine level?
A high fructosamine level means that the average blood glucose over the previous 2 to 3 weeks has been elevated. In general, the higher the fructosamine level, the higher the average blood glucose level.
What do fructosamine levels indicate?
Fructosamine levels indicate the average level of blood glucose control over the past 2-3 weeks. In individuals with diabetes mellitus, an increased level of serum fructosamine is associated with prolonged hyperglycemia for 2-3 weeks prior to testing.
Is high fructosamine bad?
Higher fructosamine levels have been reported to be associated with risk of overall mortality in people with cardiovascular disease. There is evidence that fructosamine is a good indicator of hyperglycemia in subjects with and without diabetes.
What is the difference between fructosamine and HbA1C?
The difference in the tests is that the Fructosamine measures the average over a period of 2-3 weeks, while the HbA1C measures the average over a period of 2-3 months. The HbA1C test reveals more long-term glucose control, while the fructosamine test reveals short-term.
What causes elevated fructosamine?

How reliable is fructosamine?
Unlike GA, a large number of clinical trials have reported poor correlations between fructosamine and glycemic control in patients with renal failure. Nunoi et al63 and Morgan and colleagues64 demonstrated that fructosamine is not a reliable marker of medium-term integrated blood glucose in diabetic patients with CKD.
What is a normal range for fructosamine?
For people without diabetes, the fructosamine range should be 175-280 mmol/L. For people with controlled diabetes, the fructosamine range should be 210-421 mmol/L.
How do you lower fructosamine?
Initial studies suggest that drinking herbal and oolong tea may help lower fructosamine levels in diabetics [45, 46]. Exercise regularly. Exercise improves blood sugar control and decreases fructosamine both in people with type 1 and type 2 diabetes [47, 23].
