Blood biochemistry: fructosamine

Contributor(s): David Bruyette, Audrey K Cook, Jane Miller

Overview

  • Glycosylated/glycated protein complexes.
  • Form in blood in non-enzymatic, non-insulin-dependent manner.
  • [Fructosamine] proportional to [glucose] over life span of proteins (1-2 weeks).
  • Provides long term view of average blood glucose Blood biochemistry: glucose.
  • Changes in blood glucose are reflected within 7-10 days by changes in fructosamine concentrations.
  • Less affected by short-term factors: stress, feeding, exercise.
    Very useful in cats to differentiate animals with stress hyperglycemia from true diabetics.
  • Useful in diagnosis of diabetes mellitus Diabetes mellitus and to monitor response to insulin therapy.
