When do you use fructosamine instead of A1C?
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.) You have sickle cell anemia or other hemoglobin variants3.
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.
Why is fructosamine test ordered?
When is it Ordered? If you’re diabetic, your doctor may test fructosamine to see how well you control your blood sugar levels. This test is especially useful to monitor short-term effects of changes in diet, exercise, or medication, without having to wait a couple of months to test HbA1c.
Can you diagnose diabetes with fructosamine?
The fructosamine test is not used to diagnose diabetes. The World Health Organisation recommends a glucose or HbA1c blood test if diabetes is suspected.
How is fructosamine converted to A1C?
HbA1c and fructosamine are highly correlated. The relationship between the fructosamine level and the HbA1c level can be present as a linear regression analysis, as follows: HbA1c = 0.017 X fructosamine level (µmol/L) + 1.61.
Is fructosamine more accurate than A1c?
The American Diabetes Association (ADA) recognizes the utility of both tests, and says that fructosamine may be a better choice when A1C cannot be reliably measured.
How is fructosamine converted to A1c?
How do you convert fructosamine to HbA1c?
HbA1c = 0.017 X fructosamine level (µmol/L) + 1.61.
Is fructosamine more accurate than A1C?
How does fructosamine test work?
Fructosamine is a compound that is formed when glucose combines with protein. This test measures the total amount of fructosamine (glycated protein) in the blood. Glucose molecules will permanently combine with proteins in the blood in a process called glycation.
What is the relationship between the HbA1c blood test and diabetic control?
The American Diabetes Association has recommended glycated hemoglobin (HbA1c) as a possible substitute to fasting blood glucose for diagnosis of diabetes. HbA1c is an important indicator of long-term glycemic control with the ability to reflect the cumulative glycemic history of the preceding two to three months.
