title: Serum fructosamine measurement: a new diagnostic approach to renal glucosuria in dogs.
abstract: Measurement of serum fructosamine, 1-amino-1-deoxyfructose, is commonly used in diagnosing and monitoring hyperglycaemic disorders, such as diabetes mellitus in dogs. Serum fructosamine indicates long-term serum glucose concentrations and replaces serial serum glucose measurements. This study investigates the clinical usefulness of serum fructosamine in differentiating conditions other than diabetes mellitus characterised by glucosuria. Four dogs presented with glucosuria all had serum fructosamine concentrations within or close to the reference range (313 micromol 1(-1), 291 micromol 1(-1), 348 micromol 1(-1), 262 micromol 1(-1) reference range: 250 to 320 micromol 1(-1) indicating that a single serum fructosamine measurement is a simple and efficient way of verifying concurrent persistent normoglycaemia. Therefore, serum fructosamine is a useful parameter not only in diabetic patients, bu also in differentiating conditions in dogs characterised by glucosuria without hyperglycaemia, such as primary renal glucosuria and the Fanconi syndrome. To distinguish between primary renal glucosuria and the Fanconi syndrome, measurement of the amino acid concentration in urine was performed.
