What is the primary use of the fructosamine test?

The fructosamine test is primarily used to assess long-term glycemic control in individuals with diabetes. It measures the average blood glucose levels over the previous 2 to 3 weeks by assessing the amount of fructosamine, which is formed when glucose binds to proteins in the blood. This is particularly valuable in situations where monitoring HbA1c levels may not be feasible or accurate, such as in patients with certain hemoglobinopathies, recent blood transfusions, or other conditions affecting red blood cell turnover.

This capability makes the fructosamine test a helpful tool for evaluating and adjusting diabetes management strategies, providing a more immediate reflection of glucose levels compared to the HbA1c test, which reflects glucose levels over a longer period of about 3 months. Proper interpretation of fructosamine levels can guide healthcare providers in making timely and effective changes to treatment plans.
