What is fructosamine blood test used for?
Fructosamine testing may be used to help people with diabetes monitor and control their blood glucose levels in cases where the A1c test cannot be used and/or a shorter-term monitoring window is desired. The level of fructosamine in the blood is a reflection of glucose levels over the previous 2-3 weeks.
What is the fructosamine test?
The fructosamine test for diabetes is a blood test that measures average blood glucose levels over the two or three weeks prior to when the test is performed. While similar to the hemoglobin A1C test (HbA1c), which measures average blood sugar over the previous two to four months, it is not as commonly used.

What is fructosamine spectrophotometry?
Fructosamine – The fructosamine assay is useful in monitoring the degree of glycemia over short-to-intermediate time frames (1-3 weeks). A fructosamine concentration greater than the established normal range is an indication of prolonged hyperglycemia of 1-3 weeks or longer.
What do fructosamine levels indicate?
Fructosamine levels indicate the average level of blood glucose control over the past 2-3 weeks. In individuals with diabetes mellitus, an increased level of serum fructosamine is associated with prolonged hyperglycemia for 2-3 weeks prior to testing.
Is high fructosamine bad?
Higher fructosamine levels have been reported to be associated with risk of overall mortality in people with cardiovascular disease. There is evidence that fructosamine is a good indicator of hyperglycemia in subjects with and without diabetes.
Why is my fructosamine high?
The main cause of high fructosamine levels is high blood glucose. Fructosamine will increase with your blood glucose levels in the previous 2-3 weeks [1]. Monitoring the trend of values will give your doctor more information than a single high value.
What is a normal range for fructosamine?
A serum fructosamine (a glycated protein) level, similar to a hemoglobin A1c (HbA1c) level, enables assessment of long-term glycemic control in patients with diabetes mellitus. Normal values vary in relation to the serum albumin concentration and are 200-285 µmol/L, when the serum albumin concentration level is 5 g/dL.
How much does a fructosamine test cost?
No national standards exist for glucose or fructosamine testing. The manufacturer’s suggested retail price for the test is $99, which is on par with the cost of fructosamine testing—the only current standard in veterinary medicine.
Is it possible to test for fructosamine at home?
No. Since the fructosamine levels of people with well-controlled diabetes may overlap with those of people who are not diabetic, the fructosamine test is not useful as a screening test for diabetes. Can I test for fructosamine at home? No. Although a home test was available in the past, it was discontinued in 2002.
What does fructosamine stand for in blood test?
Sugar (glucose) in the blood tends to stick to proteins. Fructosamine is formed when a sugar and a protein (usually albumin, but also globulin, or lipoprotein) are combined [ 1 ]. Similarly to HbA1c (glucose + hemoglobin), fructosamine is a measure of the amount of glucose in the blood.
When to use fructosamine instead of an A1c test?
The fructosamine test may be used when monitoring is required and an A1c test cannot be reliably used, as in cases of a shortened RBC life span or in some cases where the person being tested has an abnormal hemoglobin. What does the test result mean?
When to take fructosamine for glycemia control?
A fructosamine concentration greater than the established normal range is an indication of prolonged hyperglycemia of 1-3 weeks or longer. The higher the fructosamine value, the poorer the degree of glycemia control.
