Fructosamine

CPT Code(s)

82985

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.

Methodology

Spectrophotometry (SP)

Limitations

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

Reference Range(s)

190-270 umol/L
