What is a normal level for fructosamine?

A normal fructosamine level for a person without diabetes is 175 to 280 millimoles per liter, according to Johns Hopkins Medicine. The range for someone with controlled diabetes is 210 to 421 millimoles per liter, and for uncontrolled diabetes, it is 268 to 870 millimoles per liter.

The patient’s age and sex can affect fructosamine levels, and watching the long-term trend in the level may be more important than the exact number, states Johns Hopkins Medicine. The fructosamine level indicates the average blood sugar level during the two to three weeks prior to the test, and it can be useful for intermediate-term monitoring of glycemia, including the tracking of changes during pregnancy.
