Hemoglobin is the molecule responsible for carrying oxygen in our blood. When a molecule of a sugar (which can be glucose, galactose and fructose) is attached to it, it is called glycated hemoglobin. The glycated hemoglobin measurement allows you to have a reliable estimate of the blood sugar level in the last 3 months. Physiological values ​​of glycated hemoglobin are 20-42 mmol/mol, which correspond to approximately 4-6% of the total circulating hemoglobin, or an average glycemia of 100-150 mg/dl. We carry out the self-analysis of this parameter, through the use of high precision devices, comparable to those in hospitals.
