HbA1c Glycosylated hemoglobin

Glycosylated hemoglobin (HbA1c) is the part of hemoglobin in erythrocytes combined with glucose. The HbA1c blood test reflects changes in glucose concentration in the body over a 3-month period, and is therefore an indicator of the effectiveness of diabetes mellitus (CD) treatment, measured as a percentage. In healthy individuals, glucose levels return to normal after a tolerance test. Impaired glucose tolerance must be clarified and corrected, as ignoring it can promote vascular complications.
