Which test is most widely used to assess short-term glycemic control?

The assessment of short-term glycemic control focuses on evaluating how well an individual has managed their blood glucose levels over a period of days to weeks. The most widely used test for this purpose is fructosamine.

Fructosamine measures the concentration of glycated proteins, primarily albumin, in the blood, reflecting average glucose levels over the preceding 2 to 3 weeks. This time frame allows healthcare providers to monitor changes in glycemic control more rapidly than other tests that represent a longer-term view, such as glycosylated hemoglobin (HbA1c), which reflects average blood sugar levels over the past 2 to 3 months.

This makes fructosamine particularly useful in situations where changes in therapy have been implemented, or there may be a need for more immediate feedback regarding glucose control, such as in patients experiencing fluctuating glucose levels. Thus, fructosamine is considered the more appropriate choice when assessing short-term glycemic control compared to the other testing options provided.
