Fructosamine

Order Code: FRUCT

Test Summary

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.
