Spectrophotometry (SP)

Setup Schedule
Monday - Friday

Report Available
3-6 days (From receipt at performing laboratory)

Limitations
Variations in levels of serum proteins (albumin and immunoglobulins) may affect fructosamine results.

Reference Range
Effective 10-28-2019
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.

Performing Laboratory
Quest Diagnostics
