Limitations
Patients with low albumin concentrations may exhibit depressed levels of fructosamine.


Reference Range
205-285 umol/L


Clinical Significance
The fructosamine assay is useful in monitoring the degree of glycemia over short-to-intermediate time frames (1-3 weeks). A fructosamine concentration greater than the established normal range is an indication of prolonged hyperglycemia of 1-3 weeks or longer. The higher the fructosamine value, the poorer the degree of glycemia control.
