Fructosamine Blood Test - More Information
The fructosamine test, also known as a fructosamine blood test and fructosamine lab test, measures the fructosamine blood level.
Fructosamine is a special type of molecule found in the blood that results from the combination of a sugar molecule and another molecule known as an amine. Fructosamine levels can be measured using this fructosamine test, and fructosamine blood testing is frequently compared to the hemoglobin A1c test because both assess blood glucose levels over a period of time. In contrast to the A1c test, however, the fructosamine test estimates average blood glucose levels over the past 7-21 days (depending on the person). As a result, the fructosamine lab test is sometimes measures with the glucose test by people with elevated A1c levels who want a more precise measurement of glucose control.
While the A1c test is more widely accepted as a measurement tool for diabetes, the fructosamine test may have greater value in specific situations. In particular, this blood test may help measure average glucose levels in people who may experience rapid changes in their average blood sugar levels from rapid dietary changes, pregnancy, and red blood cell conditions. That being said, the fructosamine test cannot make an assessment of how tightly the blood glucose levels have been controlled over time ("glycemic variability") and requires the assistance of newer tests like the GlycoMark blood test to do that.
To get a fructosamine test at a lab near you, just order online and get your blood drawn at your selected Quest Diagnostics lab. Once your fructosamine lab results are available, they will be available for electronic download. As can be seen on the fructosamine lab report above, the fructosamine blood level is reported as a number and can be compared against the reference range provided by the lab.
