The evaluation of fructosamine is mainly obsolete. It can still be indicated, if abnormal hemoglobin fractions, hemolysis, kidney- and/or liver insufficiency, anemia or pregnancy restrict the evaluation of HbA1c.

Fructosamines are non-enzymatic glycated plasma proteins; their concentration reflects the blood sugar levels of the previous 8 – 10 days. Around 70 % of fructosamines are made of glycated albumin and approximately 15 % of glycated immunoglobulines. The meaning of evaluation is limited in case of disorders in the blood protein composition, hyperproteinemia and hypoproteinemia, renal or enteral protein loss, paraproteinemia or acute-phase-reactions.
