Fructosamines

Serum 1 ml or 0.5 ml in small mammals

Photometry

Reporting of results on the day the sample is received (Mon–Sat)

• Fructosamines are formed by an irreversible binding of glucose to serum proteins (glycosylation).
• Determination is used for the diagnosis and long-term monitoring of patients with diabetes mellitus, as the glucose bound to serum proteins reflects the average glucose level of the past 2–3 weeks. Elevated fructosamine concentrations can also be found in hyperproteinaemia and hypothyroidism.
• Low fructosamine concentrations are associated with protein deficiency, increased protein metabolism or, in cats, also with hyperthyroidism.
• Horse: often increased in case of EMS
