What It Measures

This test checks how much sugar is stuck to proteins in your blood. It helps your doctor see your average blood sugar levels for the last two to three weeks.

Why It's Ordered

Doctors order the fructosamine test to check blood sugar control. This test looks at your sugar levels over the past two to three weeks. It is helpful for people with diabetes. Sometimes, the regular A1c test might not be correct. This can happen because of certain health problems. The fructosamine test gives doctors a better picture in these cases.
