Fructosamine is a biomarker that indicates the average blood sugar level over the past 2 to 3 weeks. It is a complex formed by the reaction of glucose with proteins in the blood.
Testing fructosamine is useful for people who want to monitor their diabetes management and for those who want a quicker view of how effective their glucose management has been in recent weeks. It is especially useful for people who have recently adjusted their diabetes medication or for whom standard longer-term tests, such as HbA1c, are not suitable.
Fructosamine provides an indication of the average blood sugar level over a period of 2 to 3 weeks. It helps in assessing the effectiveness of diabetes treatments and can demonstrate changes in blood glucose control more quickly than the HbA1c test.
A high level of fructosamine may indicate poor blood glucose control and an increased risk of diabetes complications. It suggests that the average blood sugar level has been higher than desired over the measured period.
A low level of fructosamine may indicate good control of the blood sugar level, but can also indicate a risk of hypoglycemia (low blood sugar), particularly in people with diabetes who use insulin.
Answers to what people usually want to know.
After ordering we generate a referral letter and email you the instructions. You pick a collection point yourself and book an appointment there. Blood is drawn at the location, processed at the lab, and your result arrives digitally.
Usually very quickly. Collection points typically have slots within a few days, sometimes even same-day. It depends on how busy the location is. For a few specialist analyses we first ship collection materials, which takes a bit longer.
At most collection points yes. Some accept walk-ins. This is clearly indicated per location. You choose the location that works best for you.

That depends on the test. Whether fasting is required, and from what time, is clearly stated in the instructions you receive after ordering. No surprises at the counter.
It varies per analysis: from same-day to a few working days. Standard values often come back quickly; analyses that go to an external lab can take a bit longer. You get an email with a link to your digital result, including a short explanation per value.
