A1C is a simple blood test. It measures your child’s average blood sugar level over
period of 2 to 3 months. This shows how well your child's blood sugar is controlled.
better your child's blood sugar is controlled, the less likely they will have
complications from diabetes. Your child may have other tests such as fasting blood
glucose, glucose tolerance test, or random blood glucose test. But these tests only
blood sugar levels at that moment. They don't show how well your child's blood sugar
controlled over time.
A1C test measures the amount of glucose that sticks to a protein called hemoglobin.
Hemoglobin is in red blood cells. The more glucose stuck to the red blood cells, the
higher your child’s average blood sugar has been over time.
A1C result is given as a percentage. Most people without diabetes have an A1C level
5.7% or lower.
