Fructosamine Test
The Fructosamine test measures the concentration of fructosamine in a serum sample using spectrophotometry. Quest describes it as a marker used to monitor the degree of blood sugar control over a shorter time frame than longer-term glucose markers.
About this test
Fructosamine forms when sugar binds to proteins in the blood, and its level reflects average blood sugar over a more recent window than longer-term markers do. Quest lists this assay as used specifically for monitoring the degree of glycemia over that shorter-to-intermediate time frame, rather than for a one-time diagnostic reading.
Who might consider this test?
- Because the result reflects a shorter recent window, it is often reviewed together with other blood sugar markers a clinician is already following.

Frequently asked questions
What does the fructosamine test measure?
It measures the concentration of fructosamine in a serum sample using spectrophotometry.
How is the sample collected?
The test uses a serum sample from a routine blood draw.
Do I need to prepare for this test?
No preparation instructions are listed for this test, though people follow any instructions their ordering clinician provides.
How is a raised fructosamine level generally understood?
Quest notes a raised level is associated with prolonged elevated blood sugar, with higher values tracking poorer control; a clinician reads it together with other markers and a person's history.
