In practice, fructosamine is rarely measured clinically (even in individuals with hemoglobinopathies or other red cell disorders) due to a number of pragmatic concerns. First, diabetes care is rarely changed in short (1–4 week) intervals, since diabetes medications can take months to reach a

In End Stage Renal Disease (ESRD)

Because glycated albumin (GA) has a shorter half-life than glycated hemoglobin (HbA1c), glycated albumin reflects recent glycemic control more accurately and usefully for monitoring patients with diabetic

Interpretation of results

There is no standard reference range available for this test. The reference values depend upon the factors of patient age, gender, sample population, and test method. Hence, each laboratory report will include the patient's specific reference range for the test. An increase in fructosamine in lab testing results usually means an increase in glucose in the blood.

On average, each change of 3.3 mmol (60 mg/dl) in average blood sugar levels will give rise to changes of 2% HbA1c and 75 µmol fructosamine values.

${\displaystyle {\rm {HbA1c}}={\rm {0.017}}\times {\rm {Fructosamine}}+{\rm {1.61}}}$

Hence:

${\displaystyle {\rm {Fructosamine}}=({\rm {HbA1c}}-1.61)\times {\rm {58.82}}}$
