What does Fructosamine mean?

When we need to have a much tighter control, this test can be of great help to achieve our goals, and maintain an optimal control of our Diabetes.

When we ingest foods, they convert into glucose, protein, and other nutrients that enter our bloodstream. Glucose flows through our blood until it enters the cells to be used as fuel. On the way, some of this glucose, sticks or travels attached to proteins that circulate in the blood, this union of protein-bound glucose is known as glycoprotein or glycated protein.

When glucose attaches to plasma proteins such as albumin and globulins, Fructosamine is produced. Glycated Hemoglobin or Hemoglobin A1c, refers to glucose binding with a different protein called hemoglobin.

The binding of glucose with these proteins gave rise to average protein glycation assessment methods; that way, we are able to know how well controlled glucose levels have been for people with Diabetes, as these tell us the average blood glucose or blood glucose levels over a specific period of time.

The Fructosamine determination is based on measuring glycoproteins of short-medium term life (1-2 weeks), so a fructosamine test will indicate the average blood glucose from the previous 2 weeks. The Hemoglobin A1c test will tell us how the average has been over the last 6 to 8 weeks.

The Fructosamine test doesn’t replace blood glucose checks (blood glucose monitoring), which every person with Diabetes should perform every day.

Fructosamine values are expressed in micromoles/liter, and normal values range between 1.8 and 2.8 mmol/l.

Always remember that maintaining an optimal control of your Diabetes at all times, is the best ally you’ll have to enjoy a better quality of life.


When is a Fructosamine test prescribed?


Unlike the Hemoglobin A1c test (which all people with Diabetes should get done every three months), Fructosamine is a test prescribed by doctors only in special cases, where optimal monitoring of the blood glucose levels control, needs to be verified over shorter periods of time (1-3 weeks).



Your doctor may prescribe this test if:

  • Your treatment for Diabetes is being assigned or modified
  • You have Diabetes and are pregnant
  • You have Gestational Diabetes
  • You have an acute illness and need increased vigilance for a specific amount of time (1-3 weeks)

In any case, Fructosamine is another test that will tell us how our control is, and the importance to always keep our blood glucose levels well-controlled and check or monitor them daily. This will help us prevent the dreaded complications associated with a poorly controlled Diabetes.
