Vitamin C or vitamin E: abnormal Hb glycation.Hb structural changes : the presence of Hb S (sickle cell disease) or Hb C will underestimate the HbA1c value.The presence of reticulocytes (relatively immature red blood cells): in the event of haemolysis, acute anemia or chronic liver disease, but also treatment with iron, erythropoietin, vitamin B12 and certain antiviral drugs, or a recent transfusion.However, ask your doctor if other tests will be done at the same time and if you should prepare for them. You don't have to do anything special to prepare for your A1C test(fasting is not necessary). Routinely, the most reliable assay method is high performance liquid chromatography (HPLC) (the reference method is mass spectrometry, an expensive method, reserved for only a few laboratories) The A1C test test is performed in a medical laboratory using a blood sample from a finger or your arm Note : Younger people have more years ahead of them with diabetes, so their goal may be lower to reduce the risk of complications, unless they often suffer from low blood sugar. A person who has had diabetes that has not been treated for a long time may have a rate higher than 8%. High: Levels of 6.5% or higher means you have diabetes.Prediabetes : HbA1c levels between 5.7% and 6.4% mean you have prediabetes and are at a higher risk of developing diabetes.A normal level of glycated hemoglobin : For people without diabetes, the normal range for HbA1c levels is between 4% and 5.6%.The measured Hemoglobin A1c is expressed as a percentage (%), but also in IFCC units (mmol/mol = mmol HbA1c/mol Hb).

Link between average blood sugar and glycated hemoglobin It allows, by a blood test, to evaluate the glycemic balance over a longer period (2 to 3 months).įor most type 2 diabetic patients, the HbA1c target to be achieved is ≤ 7%, and depending on whether or not this target is achieved, the doctor can reassess the patient's management (diet, physical activity and drug treatments). Measuring Hemoglobin A1c is the gold standard for monitoring the progression of diabetes (type 1 and 2 diabetes). It tends to bind to different proteins, including hemoglobin, according to a non-enzymatic process: glycation, hence the name 'glycated hemoglobin'. When the glucose level is high in the blood,

Hemoglobin A1c ( HbA1c, glycated hemoglobin) is the percentage of hemoglobin that has bound sugar (glucose) in the blood. Relationship between blood glucose and glycated hemoglobin
