An HbA1c is a type of blood test which is used to help diagnose and monitor people with diabetes.
Type 2 diabetes
Type 2 diabetes occurs when the body doesn’t make enough insulin or doesn’t use it well. Unlike type 1 diabetes, type 2 diabetes can be prevented or delayed.
Diabetes is a long-term condition where blood glucose levels become too high as the body either produces little or no insulin, or can't use insulin properly.
