Instead, the fructosamine test may be used in situations in which the A1C test may not be reliable. For example: You have had blood loss or hemolytic anemia. (The rapid turnover of your red blood cells means a hemoglobin A1C test result will be falsely low.)
How do you interpret fructosamine levels?
What does the test result mean? A high fructosamine level means that the average blood glucose over the previous 2 to 3 weeks has been elevated. In general, the higher the fructosamine level, the higher the average blood glucose level. Monitoring the trend of values may be more important than a single high value.
What is the difference between fructosamine and HbA1c?
Conclusions: In type 2 diabetes, serum fructosamine assay can better reflect average blood glucose concentration over the previous 3 to 6 weeks and HbA1c is better reflective over the previous 8 to 10 weeks.
How do you lower fructosamine?
Initial studies suggest that drinking herbal and oolong tea may help lower fructosamine levels in diabetics [45, 46]. Exercise regularly. Exercise improves blood sugar control and decreases fructosamine both in people with type 1 and type 2 diabetes [47, 23].
Is A1C the same as 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.
How accurate is fructosamine?
In a cross-sectional and longitudinal study including 10 987 subjects, Malmström and colleagues showed that fructosamine was effective in discriminating subjects with and without diabetes (AUC, 0.95), displaying 0.61 sensitivity and 0.97 specificity at a threshold level of 2.5 mmol/L (Table 1).
How accurate is fructosamine test?
Are test results accurate? In general, the fructosamine test gives an accurate assessment of blood glucose levels over the preceding two to three weeks. However, several health conditions can affect a fructosamine test result.
What affects fructosamine?
Fructosamine assays are affected by changes in temperature and by the increased presence of reducing substances in serum, for example, vitamin C and bilirubin.
What is a high fructosamine level?
A high fructosamine level means that the average blood glucose over the previous 2 to 3 weeks has been elevated. In general, the higher the fructosamine level, the higher the average blood glucose level. Monitoring the trend of values may be more important than a single high value.
