Hba1c

DefinitionThis section has been translated automatically.
Glycated hemoglobin (glycohaemoglobin), the concentration of which depends on the concentration of blood glucose. Glycosylation is a chemical process (Amadori rearrangement) in which, unlike glycosylation, the coupling of glucose to haemoglobin A takes place without the activity of an enzyme (non-enzymatic glycation).
Corresponding to the mean survival time of the erythrocytes, the value of glycated hemoglobin is increased in the case of prolonged hyperglycaemia during the last 6-8 weeks. The colloquial term "long-term blood sugar or blood sugar memory" aptly describes the valence of an HbA1c blood concentration. The value is reduced if the life of the erythrocytes is shortened.

The stable form of HBA1 (ketoamine form) consists of 3 sub-fraction lakes a,b,c. The essential fraction HBA1c comprises 70% of the total ABA1 fraction and marks the patient's blood glucose metabolism with sufficient accuracy during the last 6-8 weeks.
