Fructosamine is a marker of sugar control in the body that reflects the average blood sugar level over the previous two-three weeks. When glucose levels are raised over time, glucose molecules permanently combine with proteins in the blood. These combined molecules remain for the life of the protein and give you an average for the amount of glucose present in the blood.

Our fructosamine test can tell you your average glucose levels over two to three weeks, as serum proteins have a lifespan of around 14 to 21 days.

Both fructosamine and HbA1c tests can monitor sugar levels in the body, which is especially useful for diabetics as a monitoring tool for controlling their sugar levels. HbA1c is more common, but fructosamine may be useful where HbA1c cannot be reliably measured. That may be the case if you have anaemia, sickle cell anaemia, or thalassemia.
