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?
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 does fructosamine measure?
Fructosamine is a measure of your 2-3 week average blood sugar levels. It is used in diabetics to help monitor changes in glucose over time. However, many health conditions other than diabetes can affect fructosamine levels. Keep reading to learn more about high and low fructosamine levels and how to improve them.
What is fructosamine level?
Fructosamine levels indicate the average level of blood glucose control over the past 2-3 weeks. [2, 3, 4] In individuals with diabetes mellitus, an increased level of serum fructosamine is associated with prolonged hyperglycemia for 2-3 weeks prior to testing.
How reliable is fructosamine?
Unlike GA, a large number of clinical trials have reported poor correlations between fructosamine and glycemic control in patients with renal failure. Nunoi et al63 and Morgan and colleagues64 demonstrated that fructosamine is not a reliable marker of medium-term integrated blood glucose in diabetic patients with CKD.
Is fructosamine a reliable test?
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. These include: Cirrhosis and other liver diseases.
How do you reduce fructosamine?
Initial studies suggest that drinking herbal and oolong tea may help lower fructosamine levels in diabetics [ 45, 46 ]. Fructosamines are glycated serum proteins that, depending on their life span, reflect glycemic control over the previous 2 to 3 weeks.
Can you use fructosamine to diagnose diabetes?
The fructosamine test is not used to diagnose diabetes. The World Health Organisation recommends a glucose or HbA1c blood test if diabetes is suspected. Although not widely used, the fructosamine test may be of value in the above situations.
What are A1C levels for diabetics?
Diagnosing Prediabetes or Diabetes
A normal A1C level is below 5.7%, a level of 5.7% to 6.4% indicates prediabetes, and a level of 6.5% or more indicates diabetes. Within the 5.7% to 6.4% prediabetes range, the higher your A1C, the greater your risk is for developing type 2 diabetes.
