Fructosamine

From Wikipedia, the free encyclopedia

Fructosamine, also known as Glycated Serum Protein (GSP) or Glycated Albumin, is used primarily to identify the plasma glucose concentration over time and so assess diabetic control .

Fructosamine Glucose tolerance test Glycosylated hemoglobin

[edit] Indications

More commonly diabetics have their glucose control assessed with the Glycosylated hemoglobin measurement that assesses average glucose levels over the preceding 6 weeks; as reflected by the permanent glycosylation of a small fraction of the hemoglobin molecules in their blood. However, this is not appropriate where there has been a recent change in diet or treatment within 6 weeks, nor if there are abnormalities of red blood cell aging process or mix of hemaglobin subtypes (predominantly HbA in normal adults). Hence people with recent blood loss or hemolytic anemia, or hemoglobinopathy such as sickle-cell disease are not suitable for some glycosylated hemaglobin methods that do not account for higher-turnover hemoglobin. Fructosamine is used in these circumstances, as it also reflects an average of blood glucose levels, but over a shorter period of 2 to 3 weeks. Fructosamine is also of use in conditions, such as pregnancy, in which hormonal changes cause greater short-term fluctuation in glucose concentrations.

[edit] Interpretation of results

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