The Fructosamine test is a specialized tool for monitoring your blood sugar control over the past 2-3 weeks. It measures glucose bound to blood proteins, providing a shorter-term average than the 3-month HbA1c. This is invaluable for monitoring rapid changes in your treatment plan or for situations where HbA1c may be less reliable, such as during pregnancy. This simple blood test provides your doctor with a more immediate, agile picture of your recent glucose control, allowing for faster, more responsive care.
