Caption

Red blood cells are filled with haemoglobin molecules, all held together by a flexible, mesh-like outer membrane. The glycated haemoglobin (A1C) test measures average blood glucose level during the past 2-3 months by measuring the percentage of glucose attached to haemoglobin, the oxygen-bearing protein molecules carried by red blood cells. The higher the blood sugar levels, the more haemoglobin that will have sugar attached. An A1C level of 6.5% or higher on two separate tests indicates diabetes. A result of 6-6.4% is considered prediabetes, which indicates early insulin resistance and a high risk of developing diabetes.
