Of course, a normal hemoglobin A1c test does not mean that your blood sugars have been under control continuously for the past 2-3 months. Yet their treatment plan would need modification. This is why daily blood sugar readings are also important. A fructosamine test has been available through laboratories since the early 1980s. The main advantage of the test is that it can detect overall changes in blood glucose control within a few weeks, rather than months.
Fructosamine levels indicate the level of blood glucose control over the past two or three weeks.
This testing system includes a home blood glucose test and a home fructosamine test in one hand-held meter. This fructosamine test can be potentially helpful for people making changes in their diabetes treatment plan. It can also be helpful to people with diabetes who do not closely monitor their blood sugar levels with multiple daily home tests. Also, a normal fructosamine test doesn't mean that your blood sugars have been normal for the past 2-3 weeks. This would be uncovered by frequent daily home blood sugar monitoring.
